Panasonic make a pedelec electric bike that is popular in europe and Japan. Many bicycle brands have opted for the Panasonic bottom bracket drive.
Such well known Eurpean bike brands include Monark from Sweden and Kalkhoff from Germany.
Panasonic have recently purchased their Japanese rival battery maker Sanyo giving them access to their EV (white) cells.
The drive is characterised by a bottom bracked based unit containing the control unit torque sensor and motor.
You can see the unit on this Japanese bike costing approximately £700:
The bulk of the unit is central and positioned to give a low centre of gravity which helps with balance and stability.
Although we have sold bikes containing these systems and the similar Yamaha drive system (Yamaha xpc and Sparta Pharos) in the past, we do not sell them any more.
Although the unit worked nicely parts were expensive and companies such as Giant and Sparta eventually abandoned them in favour of more economically viable hub motors.
If you have a bike using the Panasonic or Yamaha systems and you need a service or repair we are more than happy to help.
If you have a Kalkhoff it is best of you contact 50cycles who currently import these bikes.
