    This feels much more natural than a bike with a cadence sensor, the intuitive torque sensor amplifies the cadence of yourpedaling efforts. Pedal hard and you get maximum boost. Reduce the intensity and the boost system will reduce the intensity accordingly, no more ghost pedaling. Torque sensors are also more efficient than cadence sensors because the power provided is based on how hard you're actually pedaling and updates in real time. This efficiency usually means matching your natural rhythm to conserve battery life and extend range.

    The S4 Pro Max Dual Motor is comes with new dual motor technology, which allows you to easily switch between front wheel, rear wheel, or all wheel drive modes with the simple operation of a button. We purposely dialed down the start speed of the front drive so that the bike doesn't drift and slip when it starts.
