Objective – Build an all mountain/trail E Bike
Criteria
Bike must be light, well balanced, have good suspension and handling, and plenty of torque.
Components.
1 x used Force GT (large)
1 x BPM geared motor with hall sensors (code 12)
1 x 24” rim
1 x Lyen Infineon 6 fet sensored controller
1 x Cycle Analyst V3 Beta
3 x 8AH 22.2v Lipo batteries (18s)
Outcome 8)
Weight – 24.00kg
Top speed - 53 kph
Range – 30 km (no pedalling , speeds 30 – 45 kph)
The bike has plenty of torque, on gradients it will wheel stand if you turn the throttle to fast. It gets up to speed very quickly, and is great off road.
Power Issue
When I first set it up, The controller was limited at 50A in error, because the shunt was modified. It was very twitchy to ride, wheel standing with the slightest touch of the throttle. I had the CA limited to 25A, but it still had the full 50A for the first second of throttle change. Once I corrected the settings in the controller, it now peaks at 34A and is great to ride.
I plan to paint the battery and controller box white.
Here are the build photos.
