Hello, your website has become my go to site for the little projects my wife hates. So I have a new project, without getting too specific, its a type of electric off road vehicle (slow but powerful for my son). I planned on using a SPD-36500R controller, a MOT-36500X2500B motor because I like the mount, a top speed throttle adjuster, and the steel foot pedal throttle. I have most of the little odds and ends figured out but the one thing I can't figure out is a rear sprocket for a #25 chain. I am going to be using a 1" live axle and I am unable to find an axle hub for the sprockets you have or a sprocket for a #25 chain that can attach to a 1" live axle. I noticed you offer different sprockets for the motor but I was also unable to find sprockets for an 8mm chain. I think the #25 chain would be strong enough but I would like to go to a bigger size if possible, plus rear sprockets are more easily available for #35 or 420 chains. I have not purchased anything yet because I am trying to make sure I have all these little conflicts figured out so I am able to move to the left or right with my plans. Any advice or help finding what might work would be greatly appreciated.
