Xofo Motor

Ok, I contacted them and they only want to deal with re-seller. Also, they mention there 4.1kg motor can go up to 32km/h max speed only.

So it's not really a good picture I have about the company.

I'll get motor elsewhere. Probably BBS02

you pay a little more for the 48V BBS02, it's a tried and tested formula.
Only need a 52T crank and a BCD adapter to hit your 30mph target.
Woosh will have the gear sensor in the Autumn for these kits.

I currently have 2 spare 36v battery. I was wondering if there I can buy this 36v one and have the same result?

Torque is no problem but you may lose top speed. I thought I remember reading somewhere maximum RPM for the BBS01 is 90 and BBS02 120. How fast can you pedal (on a trainer) ?

I don't mind if it overspin lol.

But I'm just worried the 36V doesn't spin fast enough or doesn't have enough power

which bike are you going to put it on? to can use Sheldon Brown and ebike.ca to simulate the project.

The 48volt 500w and 750w have a bigger motor and more power.

Currently i have a cheap dawe 26" bike because I'm planning to park it outside overnight
