Alright, I am trying to build a somewhat lightweight, balance not needed, sort of pedal assisted, vehicle for my 11yr old, with mild cerebral palsy.
Here's my idea-
I already have a pair of motor/wheels from a Gotrax Hoverfly xl, along with the 36v battery pack. I think I can buy a Razor DXT Drift trike (I know they make an electric version, but it is critical that she can pedal, and the electric Razor trike has a front hub motor) and replace the rear wheels with the two hoverboard ones. Then get a 36v controller to run everything, and I already have extra throttles, brake motor cutoffs, displays, etc. This would allow me to build something that is stable, somewhat lightweight, appropriately sized, and she should be able to pedal the front wheel normally while using the throttle to assist with rear wheel power.
What I need help with-
1) Both motors are 350w, what 36v controller can I get to run both at a reasonable (15mph+/-) speed? My daughter weighs 90lbs.
2) How do I connect both motors to the controller. The phase wires can be tied together to keep both motors in sync, right? But then what do I do with the Hall sensor wires coming from the motors? It looks like there are 5wires from each motor and a normal ebike has 6?
3) Anyone know what the single white wire is coming out of the motors?
I am pretty mechanically inclined, but have limited experience with electronics. I've built a couple ebike conversions, but don't have any electrical training or anything.
Thanks in advance,
Bruce
Also, if anyone has a better idea/vehicle, that is reasonably priced and would work better in this application, please let me know.
