We don't want to lose our disk brake and we were pulling our hair out trying to find a work-a-around.
We came across this, but it's out of stock.

(note we have a 44t)

Can Anybody help is into the right direction?

We have a Mongoose Mack 26" with Mag wheels.

We have an engine kit, but the rear sprocket is for a spoke rim. We need an adapter or an adapter with a new sprocket because this sprocket requires drilling to mount to the wheel.
