This bike obviously is not as fast on the road but still really fast! This is one of the fastest bench tests on the planet for an electric bike vs cost (E.v Performance Kit), with proof! At 5th gear we did 93km/h. We are the first in the world to design and make this dual sprocket freewheel to go on most bicycles adaptable to electric scooter motors with #25sprockets. The speedometer becomes off- the-scale at 6th+ gear. The tire spins over 100 MPH on 8th gear (160km+). The tire spun over 120MPH on our other video where the tire kills the reflector. The other video displays use of a much bigger sprocket than this one and you can hear the wind is much stronger! That ratio needed to be changed as it was not strong enough under load. The Cheapest, highest performing motor and controller is here now!
