  1. id use a qs165v2 or qs138 90h v3 for the motor
    and a bac 8000 for the controller
    if youre going to run a battery like that theres a lot of power youre not using
    whats the max amp on the bms you're using?

    awesome bike btw

  2. 15/70 gear ratio for 7kw or 9.5hp and you only got 22mph??? You should be getting at least double. Try a 18/65. I have a built Briggs 5hp on a vintage mini bike with a 18/65 gear ratio it goes 65mph and it makes ~7200rpm. I usually use a formula to calculate top speed.(Rpm/ratio x Wheel D x 3.14 /12 /5280 x60) hope that helps.

  3. You should mass produce the kit to convert gas bikes those specs you just threw out are pretty good for speed and range add a second gear to hit 50 and I bet you would sell out

  4. That’s really cool! Could you give me the link to that frame if you still have it, I have some cool ideas I could do with it!

  5. Blessed those living in a country where you are actually allowed to use your skills like that. And not choked by regulations.
