250 Solar Bike mid-drive kit

This is our own 250 watt mid-drive motor electric bike conversion kit. It can be used with any of our 36V battery options. This kit mounts in the crank and is uses a combination of both torque and cadence sensing to active power for an incredibly smooth ride. It’s rather similar to the BOSCH or SHIMANO production line ebikes with the mid-drive motor.  The conversion kit comes with both throttle and pedal assist mode. This kit is compatible with standard bikes with a 68-73mm bottom bracket. It’s a great kit to use and it enables you to run with all of your rear gears. It took a long time to find and improve upon a reliable torque sensing mid-drive kit but we’re happy to be able to provide this one to the market. Please click here to see the installation manual.
