Hi
Finished up CEF55 recently. Overall nice frame to build. Done 140km@3050m on single battery charge (about 7h of pedaling). Geometry is up to date, like the bike feels on the trail. There is no bridge in between seat stay's so there is a bit of a flex at the rear wheel (less than in orbea rise, but in similar way), which is not a bad thing.
Decided to make a small PCB for automatic light with a bit higher output, now I can not live without it

A few minor things:
-Max insertion length for seat post in L-arge frame is 295mm !! So be careful when choosing one.
-Lower/rear frame motor mounting have a bit too big clearance, had to prepare 0.7mm thick distance washer to keep the motor tight
-Left side of the frame is rubbing on the motor casing around drive axle, just about 15 mm above, motor housing need to be grinded a bit
-Some of the bolts have 4mm allen key hole which is a bit too small for bigger torque, so be very careful during assembly.

Bike with 1kWh 48V battery, enduro wheels and enduro casing tires weights 21.85kg which I think is OK.

Recommended.

We want a e-mtb with a DJI Avinox motor instead. Please make this design available for us!

For what ? SIM card, GPS tracking, etc. No sense at all.

Only BAFANG all the way = freedom of eMTB.

Cable routing is only headset - I have asked that question already to sales team.
But I think there should not be a problem to DIY it Yourself.

A few fresh pix bellow. I think it is interesting option. Just wondering how about that storage door with attached a full water bottle to it.

Another cef50 build.
12s4p battery, about 22kG, coil shock and coil fork.
Very happy with the build.
