Attach the lock mechanism onto the seat tube of your bicycle using the provided hex key. Once installed, the Rubbee X can be inserted and removed in seconds. Take a look at the video on this page. 

There?s also a small wireless cadence sensor that must be attached to your pedal crank arm before the first ride. But don?t worry ? no wires or magnets go to or from it, just two cable ties to secure it and you?re good to go!

The Rubbee X is controlled by an easy to install PAS (Pedal Assist Sensor), sometimes called a wireless cadence sensor. Once the sensor is mounted on the bicycle pedal crank arm, it provides information about when and how fast the person is pedaling. Combining this information with the speed of the entire vehicle (Rubbee tracks the vehicle speed using the motor as a speed sensor) Rubbee can control the amount of power independently without any user interference. 

When you are pedaling, the Rubbee X provides power. When you stop pedaling, the Rubbee X stops providing power and starts freewheeling. Simple! It?s like your leg movements become an ON/OFF button. When a hill is encountered and your speed is decreasing but the pedaling rate increases, Rubbee enables a higher power output. High speed and slow pedaling will have an opposite effect ? a lower assistance level will be selected. Rubbee X makes these calculations and power modulations multiple times a second.

The power level can be controlled via the main button. Just press it to cycle through different power modes. ECO / CRUISE / POWER modes are available depending on how many batteries are installed. ECO is available with 1 installed module, CRUISE with 2 modules and POWER mode becomes available when all 3 battery modules are installed. These modes can also be changed via the smartphone application.

When the pedals are turned backwards for half a revolution, regenerative braking mode is enabled. When a long downhill section is encountered the regenerative braking can recharge the batteries. Normal operation is resumed once the pedals are turned forward.

The Rubbee X E-bike converter comes with the motor unit including 1 battery unit, wireless cadence sensor, NZ/AU charger, mounting hardware, and user manual.

Additional batteries can be purchased and will be installed and shipped together with your Rubbee X.

With 1 or 2 batteries, the Rubbee X can assist with speeds up to 25 km/h on the open road, this is the legal limit for E-bikes in many countries.

Installing 3 batteries will increase the speed to 32 km/h for off road or private road use.

The weight limit for a Rubbee X is 120 kg (264 lbs).
