Re: New to the motor bicycle world!
I have heard Schwinn is getting back to quality again but don't know for sure, I haven't built on any new ones but I just in took an old classic Schwinn to rebuild with a simple 2-stroke direct drive for a 'down on his luck' guy that lives in my general neighborhood.
I have simple advice for new builders, start with a good bike and go from there.
If you go cheap with poor installation for the motorizing no biggie, pull it off and you still have a good bike.
Go the other way, well, if you start with crap it will always be crap.
