Curious if anyone has any experience with these. They caught my eye when poking around at cheap metal full suspension frames with room in the triangle. I can't find much info on the frame itself, but the same brand of forks seem to be fondly spoken of with respect to budget options.
I want full suspension for an ebike build. My current hard tail rides a bit rough over bumps when I'm at speed. So I'm on the hunt for a sub $600 frame that is not carbon fiber

watching with interest, as looks a half decent frame
-
I stumbled across the odd e-bike build with it, as well as some very close derivative frames. Or at least frames that use some of the same base tubes. While I've not seen anyone openly raving about it, I've also not been able to find any complaints.
I went ahead and ordered one. Will keep everyone updated
-
Very interested to see how this works out as a potential alternative to a used frame for my son... if it can handle the abuse!
I couldn't see what the travel is. Any ideas? The geometry looks OK, and seems to assume a 130mm-150mm ish fork.
-
Frame showed up yesterday
Initial impressions: Feels pretty solid. Seat tube is 1.8" aluminum. Other sections are 1/4"
All pivots are sealed ball bearings like what you would find in a skateboard
no rattles or loose bits in the frame
The frame was tweaked about 2mm in shipping. Unknown if this will cause issue or not. Going to build it this weekend and determine more at that point.
Welds all check out. Some of the finish work regarding the paint isn't perfect, but it's nothing I'm concerned about either, especially in the context of a $300 frame.
Included headset is actually pretty good quality. Sealed bearing variety. Press-fit parts all have good tolerance.
The seller indicated that the fork should be 120-160mm, so I'm guessing it was designed around 140. I'll be putting a 160 on it.
Rear travel measures out at approx 130mm
My largest complaint during assembly was on one of the rear pivot arm for the suspension. There are some included shims for the bearings that are a bit fiddly to install.
Included hardware feels a bit cheap, not certain if it's stainless or just chrome plated. But it's nothing that appears proprietary. Looks like m4/m5 hardware.
I am concerned about the rear derailleur hangar. The positioning of the bolt holes appears that it might have a propensity to snap instead of bending. This isn't inherently a bad thing, however, I've been unable to locate a replacement for it thusfar.

I've had good luck shopping on eBay for RD hangers. I never know what I'm looking for specifically but a few sellers have reference pictures that I just match mine to. I always keep a spare in my tool kit.
-
Well
I never could find any 'locally' available derailleur hangers. I ended up ordering a 5 pack from Ali to keep in the box-o-parts.
Early thoughts on the frame: It's *seriously* impressive for what it is. Couple light jumps, root-stairs (think hiking path), higher speed riding (35+ mph) all feel stable and controlled. Accessories might be difficult to find/fit. There's no center mount for a kickstand. No threaded accessory areas on the rear. And the swing-arms are a bit too large to for most kickstands to fit.
Also of note, the seat post diameter is 30.9mm. The listing indicates as such... But I feel it worth mentioning as the drawings indicate 30.8.
I also go a himalo "180" (actually 160) front fork and a DNM rear shock for it.
The fork: also no complaints. Not quite as free moving as higher end offerings from Fox. Rebound / compression adjustments are pretty limited. There's a little bit of fork flex if you stare at it, but nothing that translates to the riding experience.
The rear shock: Honestly this one's been a gem. Have nothing bad to say about it. The compression adjustment is on-off as opposed to the listing's lightly-implied 3 position switch. I found I had to put the pressure up higher than the included chart indicated. But otherwise, it's all in-spec. I'm 165lbs with a mid-drive motor on it and I'm running it at 200 out of the rated 250psi. If you're over about 190lbs, this might not cut it for you.
-

whats the above ? .. some kind of electric motor assist ?
-
Correct.
I have a BBSHD kit on it. So, motor + battery adds 20-25lbs of weight in the frame
-
How did this turn out for you? Able to fit a decent size battery? Going to do a bbshd conversion on a nukeproof scout later this year and my biggest worry is frame clearance for battery.
-
I put a 13ah/52v unit from UPP in. There is a LOT of extra space. I reckon you can fit a jumbo shark or similar in there without issue. If you went a triangle style, I reckon you could fit 1.5kwh of battery in there if you were careful with it.
If you need, I could get some measurements of how much space I have in the 'triangle'
https://i.imgur.com/5cWv976.png
-
How are you finding the bbshd kit? Debating between it and the bbs02. And the upp battery, they seem good value, any issues? My only problem with the frame your using is how low the motor sits, other than that it's ideal. What sort of sustained throttle only speeds on flat are you getting and range.
-
With the BBSHD you can reach 60-70km/h... in aero position ;)
Coupled with a 3 speed Sturmey-Archer hub at the highest gear.
-
The motor definitely dangles low. Makes for a bit of a low break-over angle. But with respect to things that have all-tires off the ground like jumps, or general comfort street riding - no issues. Can go up and down curbs just fine. I just can't take it over say..... One of those bumps for car parking, or a log in the middle of the trail.
With my current config, I'll top out around 32-33mph on flat. That's with knobby tires and a relatively upright riding position. With my older (smooth) tires, I'd get 34-35mph. That's with the fenders, rack on it, backpack, street clothes. I'm sure I could get closer to 40 if I was riding tucked in and didn't have the other stuff on. But that's not really my use case - I wanted something comfortable I can commute on as well as have some fun.
It's funny that y'all mentioned the cs-rk3. That's the exact hub I'm running, coupled with an 11-50t wide range. Have a gear for every occasion!
No complaints so far with the UPP battery itself, though the included charger should be thrown in the trash. Long story short, there's a diode isolation setup on the charge port (which is good) that is bypassed when the battery is switched on. The charger's output voltage seems to be designed around plugging the battery in with the unit switched off. It outputs 59.5v - which would charge beyond 4.20v per cell. Lifespan wise, the battery seems to be holding up decent. Last time I checked capacity on charge, it was 11.8ish aH out of a rated 13. It's 8 months old. Take that number with a grain of salt though - the last couple amp hours are going to be really depending on how I discharge it / voltage sag when the motor cuts off. I really need a few more months to plot degradation over time. I know you can get actual battery testers. I just don't have one.
Range wise - honestly that's really difficult to say. It's extremely dependent on how it's ridden and how much I pedal. Really just need to familiarize yourself with your own riding style and just do math from there. I hate to give a nothing-answer, but that's about the most accurate I can give. OEMs generally rate their bikes on low PAS under ideal conditions, but that's not necessarily reflective of the real world. I know from my use, I'll range anywhere from ~5wh/mi just casually on a flat trail (which would be 100+mi range) to 50wh/mi if I'm in traffic or riding it like a dirt-bike(which would be like 10 miles of range). Depends on the terrain and my pedaling.
For the HD / 02 - I've not used the bbs02 so I can't speak to that. But the bbshd has been nothing but reliable for me. I have an egg-rider display, so I've tuned it to my preferences regarding power output, street and offroad settings, and battery settings. The HD PAS is cadence based. The 02 is a torque sensor. Cadence is fine if you're going a relatively constant speed, it hasn't bothered me any. It feels a bit more like cruise control set on your gearing. I keep dogging Luna for their ludicrous controller but they guard it quite closely :P
-
Thanks a million, great information. The bbshd can be run fully with a throttle correct? My use case is going to be 95% commuting to work (20km round trip) with possible trips to the nearest big town and back (50km round trip), and as work has no showering facilities and I'm a sweaty fucker on the best of days pedaling is a no go where at all possible. Most of that will be flat roads with very little elevation btw.
Bike I'm hoping to use is a 2016 nukeproof scout, hopefully will fit a 52v20ah jumbo in the front triangle (if not maybe under the downtube) and then I'll try to fit a clip on rear rack that can hold a battery to use for extended range, probably another 52v20ah.
Are 12sp groupsets strong enough these days? Thinking of using the existing 12sp ltwoo derailleur/shifter with a full steel 11-36 cassette and chain and a 44t chainring up front.
I've heard ap lot about the eggrider display, what's special about it?
-
...It's funny that y'all mentioned the cs-rk3. That's the exact hub I'm running, coupled with an 11-50t wide range. Have a gear for every occasion! ...
Wow... 33 speed :D
I'm just with the bare bones hub.
-
Correct, it can be used with a throttle only
Honestly, not sure about the 12sp groupsets. I run a 9 speed. Parts are cheaper, more available, stronger. I've found the wide steps between gears are a bit more desireable on an ebike so you're not spending all your time shifting when accelerating.
Eggrider: It's small, doesn't draw attention, and is unintrusive to the cockpit. I can also program the bbshd on the fly with my phone, vs having to get a dongle and a laptop.
It has a pretty neat HUD on your smart phone, but I've never used it as I ride with my phone in my pocket.

Too bad, they don't have any in stock
-
Still using 'er daily!
Decided to get a cumulative weight.
Me, with clothing, shoes, pocket schmoo: 180lbs
bike: 40-45lbs
Motor+battery: 20lbs
Other accessories - rack, headlights, kickstand, panniers: another 8-10 or so
Backpack: ~5lbs
Lock: ~5lbs
Groceries: 30-40lbs
Total rolling weight? Just shy of 300.
Not the heaviest thing out there. But definitely far from lightweight. Frame and other components have yet to skip a beat. Get shat on by the bike guys for using 'cheap' parts. But ya know what? 300lbs with a motor on it and nothing's showing any fatigue as of yet? I'm pleased as punch.
For the himalo 180 fork: it's not an oil bath system. It's just greased internally. The grease gets wiped away from the moving parts periodically. What I've done to minimize maintenance and labor time after seeing the inside (it's literally just bushings and a dust wiper) is replace the screws on the back of the fork with some low-profile grease fittings. Whenever it starts to feel like it's moving low speed bump sensitivity, I toss a pump or 2 of grease in there and cycle the thing. The stuff I'm using is just what I had on hand, NLGI2 silicone grease. Using a grade 0 semi-fluid grease would probably be better. But meh. Cheap fork = I can't be bothered to split hairs on maintenance. But so far, it's been a champ. I also put about 5ml of motor oil into the air chamber to take up some volume as I found I was hitting my front fender on bottom-out. Only thing I've noticed is that the compression adjust (lockout) seems to spin at the end of the clicks vs. coming to a firm stop. Functionality doesn't seem to be otherwise affected. Happy with it so far!
On the DNM rear shock: Nothing to note there. Haven't paid close enough attention to see if I've needed to add air or not since I tend to adjust it quite a bit depending on the riding I'm doing.
For the frame: Haven't had any issues with the bearings in there, or the pivots loosening up since I did that loctite+retighten operation. The paint on there will chip if it gets smacked by a rock. But the cheapest black satin primer/paint from the local store matches it close enough for my needs.

New member here, long time lurker.
Does anyone have any information on this frame being offered on AliExpress by a few different vendors?
https://www.aliexpress.us/item/3256804479558687
Ideally looking for any first hand experiences, or even an actual vendor website.

Since I have no self control I bought that exact one at the beginning of the 11/11 sale. I feel like the "HIMALO Store" is the official one but if nothing else they have really good ratings. It probably has another 7-10 days before it gets to me since it just landed in Alaska and I'm in eastern Pennsylvania. I'll post some pics when it gets here.
-
I would be super interested to see some pics when they arrive.
On paper, it looks like the frame has modern-ish geo, but the thing that is most intriguing is the facts its the only Al frame Ive seen that has boost wheels.
I think its a bit quirky that it's got a ZS55, rather than 56 on the lower HS cup.
Also be interested to learn how the bike works with short stroking the shock; running the suggested 210X55, but also 52.5 and 50mm strokes - as that's more appropriate for the stated 66deg HA.
...I think the bottom line is that I need to get my hands on one.
-
Showed up today, packaged well and shipped in a box that is about the size of the front triangle.
It came with a super ugly headset (but free is free I guess), rear axle, and even rear shock hardware.
Welds look really good, paint is pretty good, no dents or other issues.
Without a shock - 8.36lbs (3.79kg), this is going to be a heavy build...

Same store link you posted earlier, https://www.aliexpress.us/item/3256804479558687.html Looked official to me.
-
got one recently, took 4 days to get.
It was the 17" 27.5 version, with a 140mm fork the HTA measured 65.5, STA 76.5. I ran a 210x50mm shock and measured the rear travel 133.36mm.
Bike rides good, pedal like any trail bike with a Horst Link suspension.
-
Looks good. My mostly finished 19x29 weighs about 35lbs. Not terrible but not great.
-
forgot to post the weight, mine was just under 33lbs
-
if anyone need a replacement derailleur hanger it's wheel manufacturing #309

Hey, did your frame only come with one cable clip on the drive side rear triangle?
(https://i.imgur.com/KtoOVAv.jpg)
The non drive side has a tapped hole and I'm going to flip it over there since I don't have a shift cable. Curious if it was just me.

mine is missing too

bike stayed compose and didn't loose any traction

Getting ready for the first ride tomorrow and this happened when doing a bolt check. I didn't even get to 8nm.
(https://i.imgur.com/yU6vyJv.jpg)
I had a smilar linkage pivot bolt (steel I think) to use, should do the job for now. Going to look into some stronger replacements.

Looks presentable from the outside.

I was going to post that, I didn't tighten mine until i realized before my second ride and it broke. I contacted the seller and they said they were going to send one out. I has a spare bolt of a ISCG bash kit, so I know that it's M8x1.0 10mm.

Did you buy from the "HIMALO Store" - https://www.aliexpress.com/store/1101259771 ?
Just curious since I asked them about purchasing a replacement and an extra set of the whole bolt kit, I haven't heard anything back yet. I'm looking to grab another 19" soon so if you used a different vendor I'd love to know.
Otherwise first ride was actually much better than I expected. It was quiet, active, relatively stiff rear triangle, pedals extremely well for its girth, and the BB is miles higher than the AM831frame I had before. Perfect for East Coast jank.
-
yup, same store. I seen it for a lot cheaper these days from other vendors but with a 2 month wait period.
I'm currently under forked (140MM), I plan on swapping the air spring to a 160mm soon and will see how much better the bottom bracket height is.
did you see this frame in store? I'm interested in it also

Yeah, another store had one for about half the price but then $130 shipping or something and a long lead time. It was worth it to get it in like 10 days for what was about $50 more.

I have a 140mm Lyrik and it sits really high, A2C is close to 570mm, plus I'm on 29 so it has really good ground clearance.

Interesting. With the bolts and configuration it looks like a predecessor to the frame we have.

Probably. Share a big build thread for the few of us that will grab one.
I havent been able to find the older QR version in a minute. Do they even still make it?
Not from what I believe is the official store, but I did find some aliexpress or ebay sellers with it. With so many similarly priced carbon options an alloy non-boost QR version doesn't really have a chance.

This is the frame I was talking about $320 free shipping
https://www.aliexpress.us/item/3256804485803652.html?gatewayAdapt=glo2usa&_randl_shipto=US
-
$320 with free shipping seems too good to be true. I can wait for delivery no problem if it's legit. I don't want to get scammed, though.
I'm glad I found this thread. I've been thinking about replacing the AM831 I have. I like how it rides but I have terrible creaks I can't seem to get rid of, and I don't want to keep throwing money at it chasing them.
This could be a good cheap replacement. Cyber, where you able to port everything over from your other frame? Besides the bottom bracket of course. The only thing about this frame that is concerning is the short reach. 450mm is rough. Maybe with the slack seat tube it's not bad? How tall are you Cyber? I would be on a 19" 29er also.
Please give more impressions whenever you guys have them. Thanks.

I bought one today with the 40DEAL $40 off coupon and some other misc discounts ended up being $415 and will be here in 7-10 days. Worth it over the savings to me. This one is actually to specifically replace the AM831 that my son has been riding. The awful creak mine developed was because one of the BB bearings was totally seized while the other was just about there. Made the creaking noise even without pedaling.

As for moving things over you'll need a 30.9 seat post/dropper, BB is threaded BSA, headset is a ZS44/55, and at least a 32mm shock hardware kit or some shims. First frame came with headset and shock hardware which you may be able to use. Everything else slaps right on.
This frame makes a much more compact trail bike. I built it with a 60mm stem and a lower rise bar and it is pretty comfortable. It felt a little weird getting out of the saddle the first time, more like a CX or gravel bike. That said, if they offered an XL along the same size scale that would probably have been absolutely spot on. I'm 6'1" and I'm usually at the cusp of XL but prefer L to throw the bike around.
-
I saw that coupon. I wonder if I can get $40 off the $320 frame. That would be a deal I can't pass up.
I'm also 6'1". I'm guessing I can make it work too. It's really just a back up bike to me anyway. I have another as a main bike. This may make a great second ride for when the other is down for repairs.
If the reach were a bit longer. I'd put an angled headset on there to slacken the fork and steepen the seat tube a little. I still might, but that would lessen the reach a smidge.
-
Well I jumped in and took a chance. It was only $277. How could I pass it up?

That is excellent, kinda wish I had time to wait for it.

$277 is cheap!

I'm looking forward to when I eventually get it. Just gonna switch most of the stuff over from my AM831. I see the seat post length is the same on both, but you guys say the post won't go all the way in? So when I buy the right diameter post I'll need to shorten the travel? How much post do you guys have exposed that won't go in?

Seat post length is fine but it is a 30.9 vs the 31.6 from the AM831.

this is a pic of a 150mm dropper with about 25mm sticking out. I'm 5' - 8.5" with a 29" inseam but I ride higher then most people.
-
MTBKeo- what seatpost are you using?
Cybsrce- were you able to get your seat post in all the way? What brand are you using?
I was just gonna go Brand-X. I have one on my other bike and love it.
Thank you for the replies, guys. It is really helpful.
-
Cybsrce- were you able to get your seat post in all the way? What brand are you using?
I had a 150mm OneUp v2 around so that is what I used. It also has a short insertion depth but I can drop it all the way in to test.
-
I ran a brand X on mine, I have 3 of them and they been great. all my other bikes are 31.6
-
I measured about 275mm to the bend, I can drop this 150mm OneUp down to the collar but I have it installed with 40mm out. I ride with the saddle a little lower in the mountains.
Brand-X is cool, had an external routed Ascend II or two... This OneUp was on a gravel bike that I knew I could fit more than a 120mm drop in but not quite 150mm. The abilityto adjust travel down 10 or 20mm is the selling point for me. PNW stuff is toolless to adjust up to 25mm I think. So if I were buying new I would probably grab the OneUp 210 or 180 depending on insertion depth and adjust 10-20mm to slam it.
I have two of the v1 31.6 OneUp droppers that can be anywhere from 120mm to 170mm down to the mm with a plastic shim, they're brilliant but I have nothing to put them in :(
-
Lol, the 170mm Brand X dropper says it has 274mm insertion. That's cutting it awfully close.
-
I was going to post that, I didn't tighten mine until i realized before my second ride and it broke. I contacted the seller and they said they were going to send one out. I has a spare bolt of a ISCG bash kit, so I know that it's M8x1.0 10mm.
I just realized I post the wrong bolt size. it's a M6x1.0 10mm

Both will work but the SHIMANO XT BB-MT800 is way better

New frame arrived and has different seat stay and seat tube pivot bolts. Looks like stainless steel that was freshly turned right before shipping, still had shavings in the heads. The post side is the same as our current frame. The larger seat tube pivot bolts are painted black with no writing, also have more weight like the seat stay bolts so they're probably stainless as well.
Bottom shock mount hardware is also a "raw" stainless change. I assume anyway, they didn't add the bolt so I only have the post side.
-
Is this a good thing or bad?

I broke the 7075 aluminum version on the first frame that these bolts replace so that feels like a positive change. Finish makes it feel like they had to throw the prototype replacements in the box to get it out the door.

Hey guys how's it going? I just found a crack in my current frame and need a cheap replacement for the time being. What do people think of how the frame rides so far? What are the differences in the seat stays that has been discussed? Can you post some photos please? Post the link of which vendor you guys are using? I'm thinking of doing a mullet setup with this frame. Thanks in advance

The thru-bolt side is the same as the original so it looks the same on the "outside" of the frame.
I didn't weigh the new seat stay pivot attachment hardware, it may also be aluminum. Original:

Depending on the parts you have available I think this is a great trail frame. If you don't have a 210x55(52.5,50) shock there are a lot of carbon options that are only a little more and are 4-5lbs lighter. I went with this because it was a reasonable price and I had 100% of the components to drop in, I was in the market for a 130-150mm frame that took the hardware I had and this was one of the very few options available.
I grabbed both of my frames from the official store - https://www.aliexpress.com/store/1101259771 and I think we bought all the remaining 29ers :) There are a few other stores that have them cheaper with longer lead times, got both of mine in about 7 days.

is that a bearing mount rockshox? did you use any extra spacer?

Yep, a set of 1mm shims.

I'm having a hard time finding the nylon flat washer kit I have, I couldn't find it in my order history from Amazon so who knows... I'm not finding an M8 x 1mm thick nylon washer on a Google search either. It is just to pick up slack so it doesn't have to be anything great, a stainless or black oxide would also work.
Alternatively, you can get a couple sets of these:
https://www.enduroforkseals.com/products/rear-suspension/shock-eyelet-bearing-kits/6mm-8mm-thru-bolts/SS8x17x0.5.html
The second frame has a Fox DPS with one of their needle bearings which is just as good as the roller bearing on the Super Deluxe. It'll work on anything with a standard eyelet.
https://www.enduroforkseals.com/products/rear-suspension/shock-eyelet-bearing-kits/6mm-8mm-thru-bolts/NEEDLE-BEARING-30.html
I bought that Santa Cruz specific Super Deluxe Ultimate with the roller bearing thinking that Haideli put the right shock specs in for the AM831. Of course, they had the information backward so I couldn't use it. I actually sold it 4 times - 2x on eBay, and 2x on Pinkbike - and because people didn't read the big bolded warnings it was sent back every time :) I'm happy that it works in this frame since replacing the damper is a huge pain and I obviously can't get rid of it...
-
I have the DPX2 on mine right now, I have a spare shock off my Hightower and wanted to used it on this but didn't think about running it upside down and with a shim.
the Rockshox support heavy riders like me better then fox, unless you have a suspension that has great kinetics.
most of my builds are higher end build but I love seeing what these cheaper frames can do!

Then you have a winner! Running this shock upside down is super smooth. I'm 220lbs with a backpack and I can run it with damping, not just air and open. If you know, you know :)

Does anyone know what mounting hardware this frame requires for the rear shock and a Rockshox shock?

32MM top and 22mm bottom

glad i found this forum. Just ordered the black one without stickers. Looks like it will be a little wait to arrive.
Converting frame from this recent build.
-
Received my Himalo frame in 19" for 29" today 8)
Still need to order a few items but will start the build of the bike soon :)
Just for info, the spec of the Hanger are not the same as the one for the Scoot
From what I've seen there (Left Himalo, Right Scott):
(https://ae01.alicdn.com/kf/S6462c78d18194d22bf4c4fdabb0ac0231.jpg)
Our hanger are more close to the " ICAN X-GRAVEL Vitus"
-
Thank you for that info. Would love if there was a modular replacement to allow horizontal dropouts for my Alfine IGH.
-
Marcram, why putting horizontal Drops on a full ?
You will still need a chaine/belt tensioner, but you will have to check if your axe is compatible with the width of more than 148mm (Boost) and the holes of 12mm
-
Rear axle width should be fine, but the axle cant rotate,so need to engineer some way to fix it. Ill post my solution once settled.

after 5 months, Himalo finally sent the replacement parts I need!

Did you have to remove this plate to install the motor. My BBS02 isn't sliding on, so guess I may have to remove it.
The motor definitely dangles low. Makes for a bit of a low break-over angle. But with respect to things that have all-tires off the ground like jumps, or general comfort street riding - no issues. Can go up and down curbs just fine. I just can't take it over say..... One of those bumps for car parking, or a log in the middle of the trail.
With my current config, I'll top out around 32-33mph on flat. That's with knobby tires and a relatively upright riding position. With my older (smooth) tires, I'd get 34-35mph. That's with the fenders, rack on it, backpack, street clothes. I'm sure I could get closer to 40 if I was riding tucked in and didn't have the other stuff on. But that's not really my use case - I wanted something comfortable I can commute on as well as have some fun.
It's funny that y'all mentioned the cs-rk3. That's the exact hub I'm running, coupled with an 11-50t wide range. Have a gear for every occasion!
No complaints so far with the UPP battery itself, though the included charger should be thrown in the trash. Long story short, there's a diode isolation setup on the charge port (which is good) that is bypassed when the battery is switched on. The charger's output voltage seems to be designed around plugging the battery in with the unit switched off. It outputs 59.5v - which would charge beyond 4.20v per cell. Lifespan wise, the battery seems to be holding up decent. Last time I checked capacity on charge, it was 11.8ish aH out of a rated 13. It's 8 months old. Take that number with a grain of salt though - the last couple amp hours are going to be really depending on how I discharge it / voltage sag when the motor cuts off. I really need a few more months to plot degradation over time. I know you can get actual battery testers. I just don't have one.
Range wise - honestly that's really difficult to say. It's extremely dependent on how it's ridden and how much I pedal. Really just need to familiarize yourself with your own riding style and just do math from there. I hate to give a nothing-answer, but that's about the most accurate I can give. OEMs generally rate their bikes on low PAS under ideal conditions, but that's not necessarily reflective of the real world. I know from my use, I'll range anywhere from ~5wh/mi just casually on a flat trail (which would be 100+mi range) to 50wh/mi if I'm in traffic or riding it like a dirt-bike(which would be like 10 miles of range). Depends on the terrain and my pedaling.
For the HD / 02 - I've not used the bbs02 so I can't speak to that. But the bbshd has been nothing but reliable for me. I have an egg-rider display, so I've tuned it to my preferences regarding power output, street and offroad settings, and battery settings. The HD PAS is cadence based. The 02 is a torque sensor. Cadence is fine if you're going a relatively constant speed, it hasn't bothered me any. It feels a bit more like cruise control set on your gearing. I keep dogging Luna for their ludicrous controller but they guard it quite closely :P

Wow, I'm happy I found this thread! I just got my frame and I'm building it up. I found that the rear of the frame is skinnier than it should be. I try to put my hub in (normal boost hub), and I have to pry the frame apart about a cm to get the hub in. Has anyone else had this issue? I don't think it is the end of the world, but I am a little worried that it will make the derailleur hanger a tad crooked.

I have two of them and neither rear triangle has that issue. Being aluminum it can be "stretched" and the the hanger can be aligned but that does suck that it came that way out of the box.
-
I did not have an issue with my rear Triangle.
-
I got it all put together and took it around the property a few times. First impressions are that its pretty nice. I have to pry the rear triangle apart to get the rear wheel in, but the derailleur is aligned well and shifts perfectly (SRAM GX). I'm so far surprised with the suspension, but I'll have to test it out on a trail before I start praising it. I might have to swap in a longer stem, but that isn't bad at all.

The V2 of the Boost frame is out !!!!
Now compatible UDH (which mean also compatible with Shimano direct mount as the adapter from UDH to Direct mount already exist ;) )
(https://i.postimg.cc/DZMjfTp2/S0ac9b086586541efbe0bddd1e4d89446j.jpg)
And they have also change the way the rear break is mounted, now it's a one piece molded block.
Regarding the geometry, they have also greatly improved and modernized.
Going from 66 to 64.5 for the HA and 74 to 76 for the seat
(https://i.postimg.cc/Kj9MhG0N/Scf121bcbaa264c0d89f01f8211df18f7-C.jpg)

hmm, maybe I can do a side by side comparison
-
shorter seat tube, slightly short top tube, longer reach, smaller rear tire clearance. seems to be better for me

Damn, this new updated geometry pretty much addresses all the complaints I had with the old frame. Looks like I'm going to order a new frame. For as much as I ride and my skill level this frame is perfect. The old frame rides really well. I can only imagine what this will be like.
-
Interesting. I bought one from eBay in May and while the description has 160mm rotors specified, I can tell you it's definitely set for 180mm rotors. I guess maybe it's the "new" frame. Where I ride it's a lot more climbing than descending and the headtube angle is killing me. Just wants to pull up on me. I'm going to try a Wolf Tooth GeoShift headset and see if taking some of the rake out of it helps with the climbs.

For anyone with the 29er frame, I'm wondering what size 27.5 tires could fit in the 29 frame? Could a 27.5x2.6 or 2.8 fit? Thanks.

I doubt it. While the rear triangle is longer on the 29 it gets really narrow between the tire space behind the links until it sharply bows out again for the axle. The widest 27.5 tire I have is a 2.35 but I will check it out for giggles and see how much space is available.
-
I Fitted 27.5x2.8 Maxxis Rekon in the rear of my 27.5 Himalo frame
-
If the Rekon is the tire you're after, you're in good shape since they run narrow. I have a 29x2.4WT and it measures a little over 2.2 on 30id rims.
The 27.5x2.35 Bontrager XR3 on 25id rims also measures a little over 2.2 so there was plenty of room.
As another test I put in a 29x2.8 Teravail Coronado that measures just about 2.7 at the edge of the side knobs - it fits but only just. I think just having weight on it would make it rub.
I also don't believe the reduced circumference of a 27.5 will get you any more space. Anyway, best to google some measured widths of a tire you're considering just in case.

Hi everyone, I wanted to inform you that the Version 3 of the Himalo Fast work 150 is available on the Himalo store (Ali)
Main change are:
* Shorter chainstay for the 29"
* Better tyre clearance, from 2.4 to 2.5 on 29"
* Better cable management
* Reinforced the bottom bracket and other welding
* The seatpost in now 31.6 in place of 30.9
* New screw for the pivot
* Will see when I receive it but the welding or the paint look smoother ?
Only downside I see actually is that it weight 200gr more (3730gr vs 3950gr).
I've ordered one to replace my old V1.
It will be in mint green, if I'm lucky it should be there in 3 weeks ;D
They have also planned another version with bigger travel and trunnion mount for the shock:
Himalo B2 Trunnion (https://www.aliexpress.com/item/1005006470712630.html) https://www.aliexpress.com/item/1005006470712630.html

Very nice

I've received the V3 to replace my previous V1
-
Looks like a new frame from these guys just dropped.
https://www.aliexpress.us/item/3256804479558687.html
Looks like decently modern geo, with a extremely common 210X55mm shock size, and a UDH.
Does anyone happen to know which actual manufacture, makes this frame? Or alternatively if they have a real website that isn't AliExpress?
-
Gonna need impressions when you can

Never seen that frame and I always order via the HIMALO Store
https://a.aliexpress.com/_Eu5js2v
You could ask them on the chat, they are quite responsive.
What's strange with your link is:
1) the video linked on the store page is not for the same frame
2) they only propose the frame in S
It's probably a new frame they released after the new year but it was not yet there when I ordered mine in January. Basically it's the same frame with a new location for the rear shock

Hi, I'm asking to the shop ;)
Even their name is gone :-\
I'm trying to reach them since the 13/03 but no luck... They don't answer to any of my messages and the store is still close
