Kunyun 48V 400W Adult Electric Bikes,14" Tires, 20mph, 19-22mi Range, Dual Disc Brakes, Adjustable Seat, Removable Basket, Folding Design.

I'm 5'11 and weigh 200 lbs. I was super surprised at how powerful it is and how quickly it gets me around. It was absolutely worth the money. Please read the instructions and wear a helmet! Avoid wholes in the pavement and curbs! The 3 settings are all electric that increase in speed, so to use it as a regular bike, just turn it off. This avoids you accidentally activating the electricity while simply holding the grip bar. Did it, and learned from it. Please watch your children and make them practice! I'm 28 and still got nervous. Get the protection plan too!
