Summary

TEKTONIC - First 3d printable mid drive system on Thingiverse !

PLEASE NOTE: I'm not continuing this project anymore. Currently I'm working on less complicated version 2: https://www.thingiverse.com/thing:3105152

I been working on this bike for past year, I went through 2 prototypes before I designed this one.

This bike has serious punch and is currently running on 3KW brushless motor.
Its capable of reaching up to 40mph, it's my daily commuter and been reliable.

I don't know what's your local regulations about ebikes, better do some research before getting into this build.

Main benefit of having mid drive system is that motor is linked to your rear gears. That allow you to climb steep hills or fast ride downhill without stressing motor, it feels like riding motorbike.
Thanks to freewheel mechanism I'm able to pedal without engaging gearbox.

Obviously bikes have different geometry, It fits Boardman comp large size frame, you will have to design your own brackets for different kind of frame.

Pulley profiles were generated thanks to "droftarts" and his pulley generator:
