p.s you will need to remove the kickstand and the mounting bracket when fitting a bigger motor . I put a 350w 24v and it needed moving .

Plus alway make sure u go over the wiring as its best to get it right the 1st time. I will put the wiring up on how I made it go from 24v to 36v. It best I found to g mo from 24v to 36v as overvoulting with 3 battrys is gave me more room , 4 would give me no room . 48v would be cool but no room. Plus running on a 24v controller meens switching to 36v is not hard . But u run it on a 36v controller and as soon as u go to 24v it will not run as the 36v controller has a cut off at 32v .
