and is mounting the motor itself generally not a problem, bolts right on nice n easy?
i built one worksman bike. i'm not a big fan of the frames. i mean, they're indestructable, but they look too
industrial for me. i love the wheels, though.
the coaster brake is just a standard shimano CB-E110. the kit sprocket needs some modifying to fit. check out the "coaster brake dust cap mod" thread.
the frame itself has a few minor problems for mounting the motor. you need a smaller chainring. if you're getting the bike from worksman, you can order it with a 36 tooth. also, there's a chainguard bracket welded to the seat tube that you have to grind off.
this was a conversation i had with bairdco after having a conversation with someone else, edited out a few small irrelevant (to you at least) parts, but hopefully this gets you headed in the right direction (and hopefull bairdco doesn't mind me posting this although i don't see any reason why he would have a problem with it).
