I don't mind the single speed gear. I was wondering if there is any way of knowing how the fixed gear on that GT Traffic compares to the multi-geared bikes. In fact, I would buy it right now if the fixed gear on that GT Traffic is similar to gear 5 or 6 on the multi-geared folding bike. If I'm getting a single geared bike, I want something that's kind of hard to start up but allows me to go faster once I get the bike rolling. I don't want a bike that is easy to start the pedal but have a lower top speed.

Sorry let me know if this makes any sense; new to cycling and does not know the name of any parts.
