I am hoping to put together a couple e-assist handcycles for a project I am working on with a non-profit in Ukraine. I recently built a couple handcycles using motors from Grin Tech, which are great and have helped me get to places I never thought I could go, but they are too expensive to be realistic in Ukraine. My goal is to build some demonstration bikes that the growing population of spinal cord injured war survivors could potentially leverage once the war is over.
For those interested, you can find more details on what I built in this video, https://www.youtube.com/watch?v=85ST3CPlG94. If interested more, you can also see what we are building in California at ablebodied.org..
I am looking for a rear motor that can fit a 135mm x 10mm dropouts
I would say a stack ranked list of features
1. Compatibility with BB7 disc brakes (enough clearance for the calipers)
2. Has a torque arm
3. Thumb throttle
4. Will not overheat when going up hills
5. Has regenerative braking
6. Ability to set a top speed in the computer
7. Ease of operation
So far, this is my favorite candidate, https://www.aliexpress.com/item/1005001941512775.html
Beyond any tips, any warnings about using these kits? Naturally in a handcycle that the user cannot get out of and walk, robustness is fairly important..
Thanks a lot for the help!
