E-bike System

Bosch supplies one of the most reliable and performant E-bike packages available for the Charger4 with a Bosch Performance Line Smart System (Gen 4) motor and on-board computer. 


The Bosch Performance Line Speed (Smart System motor) which is integrated into the bottom bracket of the bike, ensuring plenty of ground clearance and low centre of gravity. A Mid-Drive E-Bike provides a more enjoyable riding experience compared to a hub motor. It’s the difference between feeling like you’re riding a normal bike, as opposed to being pulled by horses.

E-bikes do not use a throttle accelerator like a traditional motorcycle. Instead the driving force is applied as you turn the pedals, contribute to a smooth application of the available power. The harder you push on those pedals, the more power your motor will put out to help you.

Sensors in the motor report to the control unit the power, speed and cadence so that the motor can apply the best power curve to support your riding.

However when you stop pedalling there is a minimal amount of friction due to Bosch’s consistent engineering improvements so you won’t be bogged down when you stop pedalling.

All Riese & Muller bikes come equipped with a walk assist function that enables riders to walk along with their bike at 6km/hr which is perfect if you have to push the loaded bike up a steep hill.

Maximum speed of assistance in Australia is 25km/hr.

The Performance Line (Smart System) motor provides up to 340% of pedal assistance accessed via 4 different modes of assistance ranging from 140-340%.

Light Technology

Seeing in low light and night time conditions is handled by the Supernova M99 Mini Pro headlamp. The rear Supernova M99 Tail Light features a brake light to keep you safe in high traffic areas.

Integrated Cockpit

The display on a Riese & Muller Bosch E-Bike is the control centre, enabling the rider to select between 4 pedal assist modes. The Bosch Smart System allows for configuration of those modes.

The Charger4 typically comes with the Intuvia100 or Kiox 300 display

Bosch Intuvia


The Intuvia Display gives the rider full control of their system as well as an overview at all times. Battery status, range, mileage totals, ride time, current motor power, time, speed and average speed are all displayed on an easy to see screen.

Bosch Kiox Display

For performance driver riders, with optional pairing to a heart rate monitor via bluetooth. The display is scratch resistant and is easily read in sunlight. This model also features map-free navigation in conjunction with a smartphone.
