Don't know what your target top speed / acceleration is but I would want more than 3kw. Your battery will not be able to handle more than 2000w (it might combust). You need a bigger battery and a better controller. I build a 3kw hub motor ebike and I get a top speed of around 40mph.
Also voltage is usually correlated with speed unless you have a controller with field weakening. Upgrading to 72v controller and battery will hopefully give you a speed boost. Usually motors can handle a little extra power, although they will get warm so you will want to make sure that it overheat.
Damn, appreciate all of the info! I think I will be upgrading to a 72V system. I don't really have a top speed preference, just need to make sure it's capable of climbing these Seattle hills. I think I'll stay away from the hub motor on this project though. Thanks for the comment!
From what ive seen those motors arent super impressive. However ive seen them perform better than yours. Maybe settings? Maybe something like a QS138-kit could be better?
The QS138 kit could be the move on this one.. just need to figure out what to do with the battery if I do that. Looking into selling the kit I have now on FB and then upgrading. Thanks for the comment!
@@CatchHellMoto I would do some research ofcourse! I think the QS138 has a version with reduction gear also. There is also the motor from the sur-ron which has alot of aftermarket parts! Controller upgrades etc. Theres also a QS165 which is an upgrade over that maybe?

Did you sell the desert sled?
Nope, it's been in storage for a couple years. Getting it back in a few days though 👌
