shortcircuit911 said:Placed an order with QS for the 138 2000w mid drive motor with 12t 428 sprocket. You know what they say "No QS Motor, No super EVs!". I think I'll finally be happy with the bike if I can make it work. Power wheelies should be no problem and hill climbing ability will be insane. Next step is to measure the hub so I can get a custom rear sprocket made. Planning on running the bike 7:1 and see what that gives me. I'm also planning on ordering a 13t sprocket from the same company just so I have a few gearing options. QS says they'll be shipping within 9 days, so we'll see when when it shows up. Until then I have a lot of thinking and experimenting to do in order to try and get this to work and be as balanced as possible. The pic below is what I'm thinking, but that may change, we'll see.
do you have the link for the motor or kit?? how much $$$ ? does it fit standard 428 sprockets or custom to fit the shaft from QS?? what is the shaft diameter and interface?? would it fit standard 420 sprocket instead?? I want one of these motors as well for my other bike..
