    Thinking of either keeping it bare metal finish it a bit and just clear coat it or go with matte black and bronze. But there is a long time to for that...

    You'll probably need to ventilate your motor very well. I'm running 7.04:1 and I had to do the following:
    - add 12v radial blower to force air into the openings on the shaft side to ventilate rotor
    - add 12v fan underneath the motor to ventilate stator
    - remove the bell shape cover to help the mechanical fan to suck air out of rotor

    The controller also sits on heatsink which are ventilated by two 12v blowers which exhaust is blowing on top of motor.

    Which belt have you used ? The Gates Carbon GT ? It has blue teeth, that's the only one which can handle this power in that width and pitch 8 (I presume).

    Yes i got the Gates Carbon GT 1400mm length 8mm pitch. Here is the latest picture with the battries fit in. I have the batteries mounted but dont have a picture of that yet.

    Still working on the ventilation aspect for the motor and Controller. Will probably have liquid cool for controller since its sitting on a chill plate. I was thinking of a heat sink as well but will decide on that after a trial run.

    The motor's bell shape is outside the bike frame. so it should be good out there.. It might help adding a blower on the shaft side.
