freewheel sproket

Anyone know if they make a free wheel sprocket for the 24v 900w motor? I have on for my 450w but it will not fit onto th 900w.

Thanks

Re: freewheel sproket

The 900W uses a 10mm motor shaft. The only motor freewheel I know of is the one you have with a shaft adapter to fit a 8mm motor. If you need to maintain freewheeling, you'll need to put a pinned-on 10mm sprocket on the front, and unscrew the stock rear sprocket and replace with a freewheel hub and sprocket of your choice. You'll have a lot more gearing choices with this set-up, and no chain or sprocket movement when you coast.

Re: freewheel sproket

TNC Scooters has the freewheel hub, bolt-on rear sprockets, and a selection of 10mm motor sprockets from 11T to 15T. You currently probably have a gear ratio of 15/90. If you use the bolt-on 80T rear sprocket, a 13T front sprocket would get you very close to the same ratio. Smaller front sprockets will give you more acceleration, but less top speed. Larger front sprockets will increase top speed, but it will take you longer to get there.

Stock Currie scooters come with a closed loop of chain. The new sprockets may both be smaller than stock, so you will need a way (chain break tool) to open a link in the chain(actually two links) and remove some chain, and re-connect with a master link.
