Cheapest option to mount sprocket onto disc hub

mattwilkinson · Mar 1, 2015

Hello,

I'm Matt from Australia

I have a disc brake equipped bike, and am interested in fitting a 49cc motorised kit on it. Now, I don't mind if I don't have the disc brake on the back, and i'm trying to get away cheaply

What's the cheapest way to mount one of these kits onto a 6 bolt disc brake hub

Thanks
Matt

Once your disc off, just set it on your sprocket and center it, mark it's holes, and drill.
A shame to loose a disc brake though, what are going to put on back to replace it?

Won't I have really poor chain alignment then?

Would something like this work? http://www.ebay.com.au/itm/MOTORIZE...429?pt=LH_DefaultDomain_0&hash=item3f462a23bd

Kings sells motor sprockets that are pre-drilled for a disk hub. (Its not KingsMotorBikes - different company). My sprocket worked well. You can see it and the stock sprocket in the pic.

Is it possible to mount the sprocket directly onto the disc hub and still have reasonable chain alignment?

Those sprockets are like $100 once you factor in shipping to Australia ($58 alone)
The only reason i'd get rid of the disc brakes if there was a way to bolt the sprocket cheaper than getting one of the Kings Top Hat Adapters
