The new eBike/Cafe Racer project is moving forward and I am excited about this new build.
Motor: Transmagnetics 532
Controller: 40A/50A or 80A/100A (race bike)
Cycle Analyst: 2 or 3
Primary Drive: 8mm pitch timing belt
Final Drive: BMX single speed bicycle chain
Bicycle drive on right side - single speed
Motor drive on left side
26" Front wheel
24" Rear wheel
Pedals (not in sketch)
A friend is CNC machining the motor and bearing plates to mount my TransMag 532 brushless permanent magnet motor. I have to make the clamps, to mount the motor/bearing plates to the frame, in the next week or so. Then I will be able to mount the motor onto the frame and start on the final design for the 'body work' and seat, and the final drive.
While I am assembling all the bits and pieces I think it will be a few months before it will be completed.
Batteries I am considering:

Controller I am considering:
I like this controller because it will auto sense my hall configuration...but it does not allow changing any settings - which concerns me. I can get a controller from cell-man or Lyen or go with a Kelly...
The drive unit is designed to slide up and down the seat tube and down tube - to allow for different bike frames and so I can position the final drive sprocket on the jack shaft up or down as needed. The slots allow me to rotate the motor/bearing plates to accommodate the frame and final drive.
