I bought a HummingBike last week. The motor is 36 Volt and the wheels are 26" It gets a million miles per gallon.
I am totally unfamiliar with this type bike, but figured I would make the plunge and learn first hand. This is a low end bike for sure, but it seems to perform well so far.
If anyone here knows about this brand, or has an educated opinion, I would be interested in hearing it.
