Leaked patent images of BMW's upcoming electric motorcycle reveal a compact design that incorporates the battery, motor, and controller within the frame of the G310R model. While the design may be tentative, it suggests that BMW is exploring options for a more affordable electric motorcycle compared to its E-Power Roadster prototype, which has been displayed previously.
A closer look at the images reveals that the components used in the design appear to be borrowed from BMW's CE-04 electric scooter. This would enable BMW to reduce development costs and time. Moreover, BMW appears to have skillfully placed the electric powertrain components to overcome the space constraints of a motorcycle, which is a significant challenge when compared to scooters that have more real estate to accommodate parts.
The battery is positioned where one would typically find the engine, with a slight tilt to maximize space utilization. Behind the battery lies a longitudinally placed electric motor, which facilitates packaging advantages by allowing for the placement of a large-sized motor. The motor appears to drive a bevel gear, which transmits power to the front sprocket that is connected to a larger sprocket on the back wheel via a belt drive.
It is not clear whether the motor in the patent design has the same performance specifications as the CE-04's motor. For reference, the CE-04 motor has a rated output of 15kW (20hp) and a maximum output of 31KW (42hp), which enables the CE-04 to accelerate from 0-50kph in 2.6 seconds and attain a top speed of 120kph. The CE-04's 8.9kWh battery powers the motor and offers a claimed range of 130km.
The control units and charger also appear to be taken from the CE-04, with one set of electronics located at the bottom. The "tank" has a hollow space that should be sufficient to store daily essentials.
Overall, the leaked patent images provide evidence that BMW is developing an electric motorcycle, albeit with an uncertain release date. However, the design suggests that the new motorcycle will be pricier than the BMW G310R, given the associated costs.
