Did first ride today.
I manged to fry one of the BMS boards, I'll get a new one tomorrow, costs 14EUR...
So, today, I hooked up temporary wiring and headed to street. It was wet and cold, so I only did couple of Kilometers.
As I suspected 20A @ 48V is not very thrilling ride. So, 50A controller with better motor will be next goal.
Said that, I must admit, that the chassis is success. It handles very nimble, suspension stiffness just the way I like it.
It's quite long frame and seating position is pretty foward leaning. Add very hard saddle, meaning it's not very comfy ride.
