After me previous plan for a compact, light weight mid drive, suffice to say that the synchronous belts and pulley system turns out to be a little more problematic in the way of reliability and torque handling.

This is my new attempt for a even more compact drive by using a planetary system. I have been looking at cycloidal reduction drives as well as strain wave reducers. Both seem very expensive and way beyond the abilities of most DIY'ers
Planetary parts are readily available and relatively cheap. I for one like to use the part available from BaneBots, and I still have some gear-sets available fro previous projects.
My planetary Gear Box has a 16:1 ratio and can handle 160NM of torque.
I have also decided to use the APS (Alien Power Systems) APS8055 50K Sensored. Lower KV means more torque and less noise. This motor has enormous torque of 9.2NM.
Here are some pictures.
