When you're doing a lot of hilly terrain, it is actually better to have a bigger sprocket. Bigger sprockets (more teeth) produce more torque. More torque = less effort to do more elevation changes. Although generally speaking, a _smaller_ sprocket will be better on range if the ride requires you to be flat out the whole time, which this seemed to require.

I think he meant the he had a smaller sprocket on the motor. Since it's a hub motor, the smaller the sprocket you have, the more torque will be produced.

That was a Hub drive motor made into a sprocket drive ? with diy transmission ? WOW Man that thing is Kicking ass. Remember when you first got it, how fast was it stock ? I wonder if you could hook light up to ignition like a car, turn key and the lights go off even if switch is on or off. THAT WAS FUN thanks for sharing.

Enjoyed the video. You should look into upgrading your controller. I bought one from Lone Star Electrek. They will also program it for around 30$ . My RSF650 is running 60v a Kelly controller KVD7212NX ( FROM LSE) , 14 tooth sprocket. I hit 43 - 45 mph . I also out weigh you by around 100lbs. Check out their comments and my bike and review is there. I'm go to upgrade my Mx650 next.

Thank you for this! I've been looking at controller upgrade options because the Kelly controller just seems a bit complicated for me to learn how to program. My buddy Toan (the guy on the 84V long fast e-bike) actually is running a Kelly controller on both his projects, but took over a year to figure out how to get it running that fast and efficient. I'll look at the LSE controller option

You might want to look into getting a Kelly controller with a higher amp because the cheaper controller you have from the Kunray kit might be maxed out at 33A like the one I have. Since your battery is around 50A output your controller bottlenecks the performance. You could get 40+ out of the bike if you get a better controller.
