I bought my self a new mountain bike about 3 weeks ago fitted my motor to it fitted great but when it came to fitting the chain it rubs on the frame it is an APOLLO bike and the rear part of the frame curves inward just enough to touch the chain with out cutting out the frame can anyone with ideas please help mick29
 
The most common cure for this, as I have read here on this forum, is to use a second tensioner wheel to hold the chain away fron the offending frame tube.
 
You can move the chain tensioner closer to the rear sprocket, or add washers to the rear axle to spread the frame apart.
 
Putting a second chain tensioner is a great idea, you could also go to your local bike shop and purchase a derailer cog with a sealed bearing and make a chain guide to push it away from the tube its rubbing on.. Did that on a friends bike a long long time ago, it worked out pretty well the chain lined up nicely with the cog teeth. Good luck :)
