Title: Electronic devices
Post by: Zoc on April 15, 2021, 02:31:54 PM
Hi wanted to Start a new topic,
Any recommondation for smart watches, bike Computers or gps Tools.
Title: Re: Electronic devices

Here are my current tools:

Strava(subscriber) has a great route generation tool on mobile.
Strava have their heatmap, all tracks/roads people went to. A gold mine.

But then I send them to Komoot, for review/rework.
Komoot has precises terrain info and types. eg: avoid main roads, cobbles, or maximize single tracks for MTB(but manual), etc.
And start to have many points of interest referenced by the community.
If they had the quick finger mapping of Strava, I would just ditch out Strava.

I then use the Karoo 2 to record my rides and navigation.
After using the Wahoo Bolt for a few years.
Karoo has a neater navigation, touchscreen, real colors.

Unfortunately they just compete with other bike computers.
Same poor in-ride interface, with ungraphical pages with numbers.
They could do real breakthrough interfaces with such hardware.
It is Android below, we are in 2021...
It has only ~7h autonomy, with bluetooth off and minimal lightning to be visible a sunny day.

It has some other quirks:
rerouting is pitiful
the karoo connects to wifi, but you need to go through an odd web page to load a track
the powermeter is lost when you pause

BUT... I love it.
Their support is amazing.
For instance they are currently fixing the power meter issue, and I'm sure it will come soon in one of their regular update.

I'll start.

GPS Bike Computer

Xoss G+
https://www.xoss.co/pages/xoss-g.html
http://aliexpress.com/item/4000971650483.html
For around 35€ a nice simple bike computer with ANT+ and Bluetooth. Supports Speed/Cadence/Heartrate Sensor.
GPS connection is okay, the GPS fix takes sometimes a bit longer (could be the place where I live), and sometimes it loses the connection while riding in the forest.

iGPSport iGS520
https://www.igpsport.com/igs520
https://aliexpress.com/item/1005001338284700.html
I bought it because I was very curious how good/bad the cheapest GPS bike computer with Navigation is. The price was around 70€.
The computer itself works great, you can connect your Powermeter, configure which data you want to see on the pages, both things the Xoss can't do.
Compared to a friends Wahoo it was also pretty accurate. 
Now to the Navigation part. I only tried it with the first Firmware 1.05 (?), the current one is 1.10, which might have some improvements.
The iGS520 has no internal maps, so it only shows you the route and gives you directions when to turn, which is fine for me as I usually ride in my home area.
Route planning is done via the iGPSport app. And it sucks. You can set the waypoints on a Google Maps map, but you can't edit/move the already set waypoints anymore. It's also more road riding orientated, planning a MTB route is even worse. Last time I tried to transfer the route to the iGS520 the App went into a loop where it starts at 0% again after the upload was at 100%.
You can log into the iGPSport Website and import .gpx-Files and also create routes for your Routebook there. But if you try to upload one of these routes the app will give you an error and won't even start uploading then.
-> The navigation feature is absolutely useless. (for now?)

Edit: With Firmware 1.10 (1.20 should be coming soon?) you can at least the routes you created online or in the app, upload to the iGS 520 also works now, but on longer routes it's quite slow.

Edit again: Firmware 1.31 is now available. It has a workout mode if you have a powermeter and also has a indoor cycling feature now. Haven't tried both of them. But, and that's much important: .gpx-Import seems finally to work!

Sensors

Magene Speed/Cadence Sensor
https://www.aliexpress.com/item/4001096008233.html
Xoss Speed/Cadence/Heartrate Sensors
https://www.aliexpress.com/item/4001157509389.html
I have the Xoss Heartrate Sensor, 2 Xoss Speed/Cadence Sensors and 3 Magene Speed/Cadence Sensors.
They all work unremarkable.
The Xoss sensors have the better mounting with 2 1 thicker O-Rings, while the Magene only has one. The smaller one Magane delivers is also too small to use.
The Magene on the other hand has the better battery cap, which needs no coin to open, and is easier to put back in.

Ive been using the Bryton Rider 420. Israel Start-Up Nation Pro cycling Team used them last year and there is a great review on them on Youtube.

Ive been using mine for over a year and it's brilliant, cheap and feature packed including linking to my power pedals ( I use Garmin Vector 3 Duals) I use on the track, road and mountain bikes. It is the best bang for buck if you want a pro level computer. Just get the head unit, then get a magene HR Belt and speed/cadence sensors. The App is ok, but only has setups for 2 bikes, but it's simple enough to manage.

Post by: tripleDot on April 27, 2021, 02:17:23 AM
I'm using...

IGPSport IGS50E
https://www.igpsport.com/bike-computers
I've used this for about 2 years now. I'm not exactly someone who uses the data to plot out some scheduling for rides or to monitor my exercise or something. So this is simple and more than sufficient for my use.

And Magene H64 Heart Rate Monitor
Only been using this since Sep or Oct. 2020. I only use it as a warning device not to hit a certain heart rate. If I see I'm approaching that figure, I simply shift down to an easier gear or take a rest.

Both devices connects seamlessly with each other.

How accurate are they? To be honest, I don't know. The IGPSport is consistently recording shorter distances (just a small fraction) compared to my Sony Experia cp running Relive. But viewing all those YouTube videos reviews or bikepackers about their cyclocomputers and cp apps, everyone is saying none of their apps/devices showed the same data. Suppose to be I can choose to connect Relive with a cyclocomputer but I just never tried to. No particular reasons, I just use them simultaneously but independently. My phone (with Relive app) is usually in my pocket. The iGPSport is visible on the handlebar. Here's a sample data of both device, same trip. These are the key differences.

                        iGPSport     Relive
Distance          16.9km      17.3km
Max Speed      29.4kph     38.2kph
Ave. Speed      15.3kph     12.1kph
AST                   52m           283m
Time                 moving      trip duration

Distance: iGPSport always came shorter than Relive. It doesn't bother me much.

Speed: This really bugged me. The difference is quite significant. During rides, I follow iGPSport but when sharing my rides on FB it's the Relive video I use.

Elevation: iGPSport is the right one, I calibrated it but I never did calibrated my cellphone for elevation. So I'm inclined to believe that my Relive Speed might be affected (although unfounded).

I didn't bother with the time as they record it differently. The iGPSport records only moving time, while Relive records the entire trip (from pressing Start to pressing Finish button, I didn't set it to auto-pause). I do like to have both info.

xoss cadence and speed sensor (a single sensor can do speed OR cadence, just need to take battery out and in once (red is speed blue is cadence light iirc) and i have the g+, kind of wish i went the extra $35 and got the gps sensor. would help for my long solo rides.

i have a wahoo tickr heart rate monitor, it was $25 in like new condition off mercari so it was the same price as magene, xoss ect, figured if it is more accurate, same price.

Smart Trainer & Accessorys

Magene ANT+ Receiver
https://de.aliexpress.com/item/4001203907500.html
Works well, but mine looked used.  ???

Thinkrider X5 Neo
http://www.thinkrider.com/?page_id=3471
https://www.alibaba.com/product-detail/Wholesale-Fitness-Equipment-Portable-Direct-Drive_1600166464905.html?spm=a2756.order-detail-ta-bn-b.0.0.32762fc2ouw8pj
I bought mine for around 420€ on AliBaba. From Order to delivery it took a whole 2 months, while shipping alone was 7 weeks. I also got a 10%/42€ AliBaba coupon, because the seller didn't ship it in a week.
Packaging was alright, but some of the polystyrene crumbled, so I had to vacuum the trainer after unboxing it. ;D
The build quality could be a bit better, the plastic of the housing is rather on the cheap side, the metal foot had some scratches/isn't that well polished. The handle is also unclean made.
That are just optical flaws and shouldn't affect riding. And it's afair the cheapest Direct-Mount Smart-Trainer available.
Other negative points:
- No power switch
- Power cable could be longer (1.2m from wall plug to power supply + 1.2m from power supply to the trainer)
- Adapters for Thru-Axles not included (12€ shipped on AliX)
Riding on it is absolutely okay, the foot flexes how it's supposed to do. On really hard out-of-the-saddle one foot might lift sometimes.
I've done around 50 km on it now, and power numbers also seem to be okay.

I'm about to finish my gravel build and my plan is to use a cheap android phone as an ad hoc bike computer. I have no idea if this will work, but if it does, I will have a full featured computer for a fraction of the cost.

Samsung Galaxy phones (generally) have ANT+ antennas, in addition to (of course) GPS and Bluetooth. I picked up a used Galaxy J7 for $50 which has the added bonus of removable batteries. I plan to mount this to a Garmin stem mount using an adhesive-backed adapter on the phone.

My idea is to try various apps that support maps/navigation with sensor overlays for speed, cadence, and heartrate. I'm looking at RideWithGPS and Strava on Android. Both of these seem to support sensors/overlays and even appear to integrate with the Garmin Varia bike radar (haven't pulled the trigger on that but it looks cool AF).

I own an ANT+ heartrate monitor already and have a couple XOSS ANT+ speed/cadence sensors on the way from aliexpress -- these supposedly support Bluetooth and ANT+. I'm hoping to get everything together in the next couple of weeks and will report back if I got it all working, and what the app experience is like.

Unrelated to bike computers, but definitely electronic -- I was considering picking up a new GoPro for my mountain bike, and I came across the CamPark v40.
https://www.campark.net/products/campark-v40-4k-30fps-wifi-action-camera-20mp-touch-screen-40m-waterproof-camera

This is a true 4k waterproof action cam that can be found for around $100 USD. They have other 4k models as well that are even slightly cheaper. I watched a couple reviews on Youtube and its quite impressive. I think the v40 even has optical image stabilization which is ridiculous for the price.

I might just buy one of these to put on my gravel bike, as a kind of "dash cam" for road rides.

What are your thoughts now on the Karoo 2?  There have been a lot of updates, but seemingly still quite a few disgruntled users, and almost universally reported still-poor battery life?

How many of the bugs and spoilers you listed have been patched up?

I tried this with an s5 and it works alright for short rides. My issue was that the battery only lasted an hour and a half to two hours at most if you have the screen on the whole time whilst using GPS and strava. The wahoo app worked better with all the sensors than strava did for me and if I didn't use GPS I'd get another hour out of the battery. This was after swapping in a new battery.

The other big issue I had with the s5 in particular was that the back cover was removable and when the road got bumpy the phone would separate from the cover (which was attached to the garmin mount) and going flying off . I tried fixing this by super gluing the back cover onto the phone but it just ripped apart a couple rides later.

So now I have a cycling computer, igpsport 620

Magene P325 CS: Dual-sided power meter and cadence sensor. It's great!  Does what it says on the tin at a price similar to a one-sided unit.

Magene C406 computer: Its fine. Inexpensive. It does the job.  Syncs to Strava and provides all the major metrics. Allows for multiple pages.  It has GPS, but does not have routes. Pages are not as customizable as the marketing leads on. I'll probably replace this in a year or 2. 

ThinkRider X5 Gen 2: Well, I don't have this yet.  Currently in the middle of the Pacific in a shipping container with 14 other units i bought.   I'm fairly confident that it will perform as well as any other unit twice it's price.

X-Tiger Smart Light: Its the one that has different pulse modes, but turns solid red when stopping.
Has a bracket that lets it hide under the saddle between the rails.  Discrete, lightweight. Claimed 20 hour life.  In reality, it might last you a century ride, but that's it.  At least in my case.

Seriously considering getting a Ticwatch Pro 3 Ultra LTE (when released) for biometrics tracking, routes, and just generally as a good all-rounder smart watch.

They apparently can't fix the lost sensor issue.
It must be a harder problem than it looks like, as they had quite a few updates since then.
Having to re-enable my power meter while riding  in a peloton after a pause, is terribly annoying and dangerous.
Except that problem, everything is fine, but it annoys me enough that I will probably switch back to wahoo at their next iteration.

For the battery life, if I plan a ride longer than 7h, I attach a 18650 based powerbank to the handlebar, for a few hours more.

Is the sensor loss universal, or just some units, or some sensors? 

I still feel like all of the options are crap.  Garmin 'just works' but maps, navigation and rerouting are all crap, and UX is prehistoric.  Wahoo Bolt V2 is laggy, they still haven't fixed their underreporting of power and work done (kJ) on anything other than Favero on any of their products & deny the issue exists, battery drain is insane when stopped or GPS is lost, no sleep mode or screen sleep mode, screen visibility worst in class. Karoo 2 - bad battery life and bugs galore - including by the sound of it a game breaking one with sensor loss.

It looses the powermeters on all my bikes, a p2m-road, sigeyi-mtb and quarq-gravel.
But it doesn't loose my heart rate either magene or a whoop.
Shifting sensors stay as well.

They made an update recently, limiting Ant+ sensors to 15, but that didn't help at all.
They told me on their support to change the priority of sensors depending the bike I ride   ??? That didn't help either.
What is stupid, is when you get to the sensor page, it finds it back instantly.
Would it be possible a smart ass there would call the same function when re-starting a ride ?

I agree with you, all these devices look prehistoric, even the Karoo, compared to other apps we use daily.

But just to be clear, except this powermeter loss. If I train myself, I could think of passing by the sensor page before restarting the ride...
As well as the shortish 7h battery life(last longer if you turn your screen off when not riding).
I'm quite happy with it.

I notice that the when on my road bike with a Stages gen 3 PM the connectivity stays strong with the K2. On my gravel bike that has a Stages gen 2 PM though the connection gets interrupted very frequently when pausing and sometimes mid spin. Connectivity with a di2 Ant+ only dongle seems good. I notice that notifications from my phone also aren't consistent and the device often needs to be connected again. Battery life isn't great. Putting into battery saving mode helps but still behind the Wahoo devices. Aside from this happy with the nav and UI and functionality.

That doesn't augur well at all IMO.

Probably means the person who wrote the call(s) that works has left, the code isn't adequately commented, and nobody there tasked with fixing it knows wtf to do. Or management has its head so far up its ass that they don't consider this a priority fix, so they have the person who knows how to make sensors work doing something else.

Looks like it won't be viable for me then.  Not prepared to fuck around with dropouts.

Have to stick to Garmin when I want accurate power and don't need routing, and Wahoo when I need routing.

carbonazza I'm happy to hear this seems to be resolved for you! but it doesn't appear to be for me :(

I updated to 1.248.1114 the day it came out and then on my ride on Saturday my 2nd gen Stages PM is still seeing drops in connection. I also moved the order of sensor priority for this PM up the list per Support's suggestion. The other gen 3 stages PM on my road bike which is at the top of the priority list doesn't have connection drops. Although connectivity on the different gen PMs is likely different, I didn't have drop in connection when using both with my Wahoo Roam.

So the K2 looks great, but has anyone seen a good, full-featured Chinese option yet?
So far the closest I’ve seen is the igs620, but that one is not without, what I would consider, deal-breaking issues with navigation.

The XOSS, Magene C406, et al are fine for the price and what they do, but are still simple, entry-level computers.

Left side crank arm works fine for over two years. Change the battery from time to time and that's it.
The right side spider sensor stopped working for me after a bit more than 12 months. Seems to be a problem with the integrated rechargeable battery.
Loads very quickly and does not last longer than 10min anymore. I guess the Li-ion battery was damaged or a problem with the charger electronics.

I got them during the kickstarter for the Sub 300 usd price tag, I 100% reccomend them. I really like the. Spot on compared to my elite turbo trainer.  They've been flawless I have to say, follow the instructions and you'll be grand.

So far so good, I didn't get much outdoor time with it before the cold weather came and it got hooked up to the trainer.  Power seems consistent, not a single signal drop so far.

You're right, after a few more rides.
I would say, it just drops less >:(

I don't think I have noticed a drop from my Karoo 2/Sigeyi PM01 on my gravel bike.  Does it just goe missing for a while or is it a sawtooth pattern in power data?  I'll have to poke through Strava.
When my BB bearings go I'll be "upgrading" to the Rival AXS crankset with the spindle mounted left side power meter hoping all that SRAM will add up to better data collection.  Not that I'm good at it or looking for better performance, I just like data...

BREAKING NEWS !

SRAM bought Hammerhead.
Hopefully this will help them to fix the lost powermeter issue  ???

Along with that I am hoping for quick AXS Web integration, only been waiting for a year now :)

I got the Karoo 2 for better mapping (over the Wahoo Roam) and the novelty of having a dedicated sim card.  I'm also not a huge fan of the new settings/drop down menu overhaul, all I want to do is lock the touchscreen and they've made that more difficult to get to now.  Just have to get used to it, I don't like to be the guy that shakes an angry fist to the sky when there are changes.
If Wahoo releases a Roam v2 I may be tempted but I'm a SRAM fan, hope they guide the Hammerhead team in a more cohesive direction in the future.  It may not reap benefits until a new unit is released.

Aside from software stuff, I hope SRAM will dump the shitty mount and use much better batteries in the next revision. 

Bryton just released the S500 with a claimed 30 hour battery life (I'm guessing 20-25 is more realistic) ...meanwhile K2 6h if you're lucky with high screen brightness, 8h otherwise  :-\

.Hey its an android. What gives the Karoo a big potencial is also its biggest downfall. They took a platform that basically allows for everything and stripped it down. Very different from building (Like wahoo for example) something from the ground up. In my view they will face alot of big challenges to keep things under control (more even when it allows for you to load side apps in the karoo).
Dont even want to think when they switch android version.
Hopefully im wrong.... 8)

The power meter is dropped after a pause, sometimes a minute is enough, sometimes it stays.
It looks to be a random issue but frequent, and once it goes, only a click on Sensors' menu gets it back.

Interesting. Web integration to do what ?

...I'm also not a huge fan of the new settings/drop down menu overhaul...
Me neither, but I start to get used to it...

If Wahoo releases a Roam v2 I may be tempted but I'm a SRAM fan, hope they guide the Hammerhead team in a more cohesive direction in the future.  It may not reap benefits until a new unit is released.
I'm looking forward to what both innovative companies will do, in any case, I'm quite happy with the Karoo 2 as long as I don't stop in the middle of a ride  ;D

From the last release note, can't believe it!

Improved Sensor Search

We’ve improved the Karoo’s sensor searching behavior to make connecting to sensors more likely, especially after breaks in the middle of your rides. Now, Karoo will search for any disconnected sensors as soon as you start moving.  :D

 ;D let us know how you make out after the update!

While I thought the issue with the frequent drops to my secondary PM was related to it not being the primary one, I think its more related to the connection between that PM and the K2 itself as I had the same issues with it once I moved it to the top of the priority list. That being said I didn't have the same issue with my Wahoo Roam. Looking forward to testing after the new update.

Looks like SRAM already fixing shit.  Albeit the note doesn't inspire much confidence "more likely".

Little post about electronic devices from me:

Thinkrider X7 Pro V3 - version with up to 8% grade, already did 3000km+ on Zwift - works flawlessly :)
