Hello, I'm new.
I have a problem with my ebike. One day it worked, the next morning I got on, exited my garage, pushed off, advanced the throttle and Nothing Happened. This was coincidentally the very day I promised to demonstrate it before the Society of Environmental Scientists at the University of Massachusetts, in Lowell MA. I wasn't happy, and neither were they.
checked voltage on bank: 37 volts, "power" light comes on on the twist grip when batteries are plugged in to controller. Pedaled around a bit with the throttle advanced a fair bit: controller got warm, but the bike didn't move under its own power. I built the ebike to replace a gas scooter that was broken and later stolen, and had a distrust of gas kit's reliability.
I dont think I could afford a new hub motor: I am an unemployed college student whose funding for this sort of thing comes from birthday/christmas and parental allowance.
the weather has gotten warmer since this happened, and I want to ride it with a functioning motor; it is a real pain getting those huge SLAs up any hill.
I really hope it can be fixed without a new hub motor.
The bike build is as follows:
Frame: Del Sol 26 inch heavy comfort cruiser
Motor: BMC v1 400 watt geared hub motor, rear wheel kit with internal freewheel.
Controller: stock no name waterproof 36 volt 25 amp; came with kit
Throttle: 48 volt half twist grip.
Battery: 36 volt AGM, 26 AH Powersonic.
Charger: Mastech universal industrial charger. a silicon rectifier smart charger. multichemistry, voltage adjustable from 6 v to 48 v, rate adjudtable from 2 amp to 10 amp.
