Testing my buddy's HeyBike Citycruiser

18 MPH max I did @170lbs on a flat smooth bike trail. Perfect cruiser bike, 16MPH steady on slow inclines. The motor pushed way more than I expected. You can use throttle only. Pedaling felt heavy but better at 8 MPH on a comfortable gear, I like gears 4 to get going and 7 once I got to 8mph.
