Re: Tips for performance and smoothness of ride ??
I balance all builds with solder wrapped around the spokes...you can buy stick on lead weights where finer golf equipment is sold.
If you are riding 1 1/2 miles each way, I'd think a moped would be a waste of money.
Your bike should do 30mph or so with a 44T sprocket once it's got a few hundred miles of break in. The engine will run smoother too.
