Bosch Upgrades Active Line Plus E-Bike Motor with Enhanced Performance and Reduced Weight







Bosch has introduced the latest iteration of its widely used Active Line Plus electric bicycle motor, which boasts enhanced power, reduced weight, and a significantly smaller form factor. This updated motor is primarily engineered for everyday cyclists, including commuters, recreational riders, and those seeking a comfortable e-bike capable of navigating diverse terrains, from city streets to weekend trails.
Despite not being Bosch's most potent motor, the enhancements are noteworthy. The new Active Line Plus now delivers up to 600 watts of peak power and 60 Nm of torque, alongside a maximum pedal assistance level of 340%. This provides ample assistance for accelerating from stops or conquering inclines, transforming an ordinary commuter bike into a capable companion without overpowering it. In alignment with its predecessor, the motor is designed for Class 1 electric bicycles in the US, offering pedal assistance up to 20 mph (32 km/h) without a throttle.
A notable advancement is Bosch's redesign of the motor's physical structure. The company engineered a new two-stage gearbox, resulting in a 17% reduction in overall motor volume and a weight decrease of approximately 1.1 lb (0.5 kg). Weighing in at around 6 lb (2.7 kg), the new drive unit facilitates easier integration into sleeker, more conventional bicycle frames. Bosch also emphasizes that the refined gearbox employs precision-machined components to render the motor nearly silent, while updated sensors and software ensure a more fluid and natural pedaling sensation. This is crucial for the Active Line Plus motor, where riders often seek an experience that mirrors a standard bicycle, simply with an added boost. Furthermore, the motor supports Bosch's eShift electronic shifting system, which can automate gear changes for riders who prefer to concentrate on pedaling rather than shifting. Bosch has also augmented the motor's sealing and bearings for enhanced all-weather resilience, and its housing incorporates approximately 40% recycled aluminum, contributing to a reduced carbon footprint in its manufacturing.
The upgraded Bosch Active Line Plus motor represents a significant step forward in making electric biking more accessible and enjoyable for a broader audience. By focusing on practical improvements like reduced weight, quieter operation, and enhanced durability, Bosch is empowering everyday riders with technology that genuinely elevates their cycling experience. This thoughtful evolution underscores a commitment to innovation that supports a healthier, more sustainable mode of transportation for communities worldwide.
