Default Re: Is it possible to Motorize a bike with coaster brake?

I totally agree with Baird, older coasters seem to work much better than modern ones.
Great response on this issue!
On my tandem (85lbs w/o riders)(390lbs w/me & wife) I reverted back to the original HD coaster brake and a front and rear caliper. I can hammer down safely using all 3 from a nominal speed of around 22-24mph nicely and not over use any one system. I did R/R the coaster with cleaning and new grease before reinstalling it. The cost of converting to disks wasn't worth it to me.

These guys are giving you great advise.
