Product Description

Super heavy duty Busettii mountain bike with center mounted motor, real transmission (auto 3 speed) chain pedal integrated drive train for smooth pedal assist at very high speeds, Comes with both pedal assist and throttle mode,(also see www.biyadii.com) 500 watt motor plus real transmission = 1000 watts of equivalent torque but just using 500 watts of power. Comes with 2 x 38 volt 10ah batteries (= 20 amp hours) with the high efficiency motor and trany can go 86 miles in pedal assis. mode or 60 miles with no Pedaling at all. Unlike most other e-bikes, Vortex Rider can pedal with motor even at 30 mph because of integrated drive pedal train system. Most other E bikes don't have high enough pedal gearing to stay up with motors at high speeds but Vortex solves this problem. Your pedaling always has a big contribution at any speed. Top speed 32 mph.

People who must commute down long straight roads everyday will LOVE the VORTEX because of the High top speed cruising ability and the fact that it uses much less power than other bikes to stay at a high cruising speed. Many high speed bikes we tested at 30 mph will use up the entire battery in just 8 miles ! The Vortex is the only bike under $5000 that can cruise at 30 mph for 32 miles on one battery charge. If you cruise at 15 mph it can run 86 miles on one battery charge.
