The Zebra does everything well - perfect for what we do. On road, off-road, hills, tracks and above all, plenty of range. It has a 20ah battery which regularly gives us 55 km + rides in the hilly countryside around us. It has enough power to pull a trailer and with the Suntour seatpost suspension, gives an exceptionally comfortable ride.
It uses a cadence sensor (as opposed to a torque sensor) and a rear-wheel hub motor. This system essentially means that you can put in as much or as little effort as you want - so when you're tired, there's no need to pedal hard just to get home.
