The frame size is a good starting point. It has to fit your leg length. For recreational bikes, you should get a lot of stand-over room when you straddle it. For high-performance bikes, you should get 1" clearance for road bikes and 2" clearance for mountain bikes.

The seat height should allow you to bend just a bit when your pedal is at its lowest point in rotation. And as you sit, you should be able to reach the handlebar without difficulty; your elbows should bend slightly.

When you buy a Dahon Folding Bike, you can eliminate a lot of transportation problems. You don't have to worry anymore about looking for a safe and dry space where you can store your bike when not in use.

There is no reason to leave the bicycle outside and run the risk of getting your bike stolen. Your concern with auto parking before you run to your office can also be cancelled. You don't have to be refused every time you take your bike into the elevator since you can fold it to look smaller and put inside a bag to look much nicer.
