I'm shorter than you, but weigh nearly 200lbs and a 2 stroke 50cc motor pulls me pretty well.

The moto-bike would fit you OK for short rides and cruising.

If you plan to take 25 mile rides, you will be more comfortable and get fewer cramps on a bicycle with 24" diameter or larger wheels.

There are Schwinn Stingrays and 20" BMX bikes on this sites with motor kits, but they don't travel long distances.
