I picked up this motor kit for my first electric kart build, thinking it would be a reasonably economical solution:
It came with a lot of parts I would have had to source elsewhere. The only problem I'm running into now is finding a sprocket hub to match the included 8mm 54T sprocket. It has a strange bolt hole circle of 64-65mm (~2 1/2") with 6mm (1/4") holes. I'm using a 1" live axle and can't find anything to match on the big online outlets that I know of (BMI, GoPowerSports, GoKart Supply, Electric Scooter Parts). The closest solution I found was at Alfa Wheels, but it's a freewheel hub, so that'd kill my motor braking and reverse possibilities:
alfa-wheels.com
That's exactly the sprocket I have, but I can't find a fixed hub to go with it.
Any thoughts on how I could proceed or other sources to try?
I realize I might be able to get whole new sprockets & chain to solve this problem, but I worry it may then be difficult to find a different motor sprocket to match this spindle. Plus, I'd like to save some money and use as much of what I already have as possible.
Thanks!
