I have old Mountian bike
I want to convert it to Cheep E- Bike But don't want use Convertion Kit.

I like to use an Elecitic Motor Attached to Roller
This would be put above the Front Wheel.
The Battrey and Speed Control would put in tool Box and attached to a bike Rack.
I use a Turn grip turn on and off the motor .

When Turn the Grip the Motor Touches the wheel and spins iot

Question where do I get the parts .
