Re: MBB: Motorbicycling Blue Book - Request
Get off the computer and go buy that.
I've been looking for one for a friend for quite some time with no luck. They're hard to find here, and when you do, they're either the newer narrow rear, or super expensive, or both. A nice steel frame would be great. (Be sure to thoroughly inspect the frame for unusual wear or cracks)
A bad wheel is a good excuse to upgrade them all, and that's a pretty cheap way to feel safe at 20mph.
Good luck! Start a build thread on your 3-wheel 4-stroke, and post alot of pics if you can.
It's cooler to not fall off your bike.
