Hey guys.
I know you might look down on a thing like this, but I bet you guys would be a good place to start for this.
I'm looking to reduce my gas usage by riding my bike more, but I'm just not really able to do strenuous commute biking on my own in my physical condition. But I'm dedicated to using my bike for the short commutes I have, instead of my car.
Is there anywhere in or around Pittsburgh that will help me install a pedal assist engine?
