- Powerful: 1000W nominal, 1500 peak, tunable pass 2000W. While torque remains constant at 160 Nm in stock form, the nylon gear was replaced with steel to allow DIY’s to overdrive the motor far pass it’s factory specification. In some applications utilising aftermarket controllers from EXCESS, ARCHON X1, Phaserunner from GRIN and higher voltage battery it’s is pushed pass 2000 Watts.
- Integration: Ultra max is quite bulky! It comes with mounting bracket, this allow for better, more sophisticated integration and freedom in bike geometry.
- Weight: Ultra Max motor weighs around 5.3 kg. It is one of the heaviest on the market. Good it’s close to the ground!
- Torque sensor: High speed torque sensor to deliver accurate assistance over a wide cadence range. Sprinting over rocky field or pedalling at an even cadence down the road? You have 9 levels of pedal assist, select the support that feels natural.
- Better design: Bafang frequently updates it’s firmware and hardware to refine the Ultra motor based on feedback and new developments. There are constant and incremental improvements as time goes on.
- Smoother: Not. Poorly refined controller result in lots of power fluctuation, delays and overruns. There is lots to improve here.
- Quiet: unfortunately not. The new motor has some noise issues – especially on full power at 1500W, comparing to Euro market leaders running 250W.
- Narrow: the Q-factor (distance between the cranks) is 175 mm is reasonable and provide natural pedalling sensation. The narrower, the better.
- Greater capacity: There are many battery options depending on the builder of the bike choice.
- Hello tuning: Tuning software, controller replacements, higher voltage battery are most popular. While the motor mechanics are over-engineered and can take far over 2000W, other elements often modified to allow motor to operate beyond OEM specification.
