Yesterday I finished up retrofitting my Cyclefab CycleTruck (originally a Kona Smoke) with a Grin Tech 20" geared motor, Phaserunner, CycleAnalyst, Sempu Torque Sensing Bottom Bracket & 846WH Li-ion Battery.
Works great so far and handles better than expected at 20mph which it rarely reached with just my legs providing power.
The front end geometry is low-trail and optimized for large front loads. Having the front load decoupled from the steering also reduces the chances of wheel flop. I was a little worried that adding an electric motor would lead to instability but it did great on the first ride with no speed wobbles.
This is my first post on Endless Sphere, thanks for taking a look. I look forward to learning more about eBikes and tweaking my Cycleanalyst.
