New rear motor from Bosch expands the competition in the urban electric bicycle market, with a lighter, quieter, and integrated proposal for daily use models, while manufacturers are already preparing e-bikes equipped with the technology to hit the market starting in 2027.
Bosch eBike Systems presented, in June 2026, the Hub Line, the brand’s first rear hub motor for electric bicycles, aimed at light, discreet urban models connected to the German manufacturer’s Smart System.
With 45 Nm of torque, power of up to 400 W, and an approximate weight of 2.3 kg, the component inaugurates a different front for Bosch, historically associated with central motors used in trekking e-bikes, mountain bikes, and higher-performance models.
Rear hub motor changes Bosch’s strategy
By entering the urban electric bicycle segment with a motor integrated into the rear wheel hub, Bosch expands its portfolio and starts competing in a category already occupied by manufacturers specialized in this type of solution.

The debut of the Hub Line also reinforces the brand’s interest in e-bike projects with a cleaner appearance, less visual interference from the electrical system, and a riding experience closer to that offered by a conventional bicycle.
Urban e-bikes gain focus on lightness and integration
Developed for everyday use, especially in urban commuting, the Hub Line seeks to offer controlled assistance in starts, restarts, and low-speed sections, frequent situations in city traffic and bike paths.
Among the main features is the decoupling of the motor when the bicycle exceeds 25 km/h, a condition in which the electric assistance ceases to operate and the system reduces pedaling resistance.
With this operation, the proposal is to make pedaling more natural when the assistance limit is reached, without the drag sensation that can occur in some electric systems.
According to Bosch, intelligent sensors continuously monitor pedaling to adjust power delivery, maintaining more precise responses during accelerations and restarts without making the ride abrupt.
Smart System brings together motor, battery, and connectivity
Within the Bosch Smart System ecosystem, the Hub Line works integrated with the motor, battery, controls, display, and digital resources, allowing manufacturers to develop urban electric bicycles with interconnected components.
The new platform also includes the PowerTube 360, a more compact battery aimed at frame integration, a feature that favors designs with discreet lines and less visual emphasis on the electric set.
In addition to the battery, Bosch introduced complementary components for this generation of urban e-bikes, including the updated ConnectModule, the LED Controller, and the Intuvia 200 display.
These items were created to enhance connectivity, control, and information reading during use, maintaining the proposal of visual and functional integration of the new electric platform.
Walk Assist helps in the daily use of the electric bicycle
Another feature provided in the system is the Walk Assist, which assists the cyclist in pushing the bicycle in situations such as ramps, garages, inclined sidewalks, or sections where pedaling is not possible.
Although common in urban e-bikes, the function gains relevance in models used daily, especially when the bicycle needs to be moved in tight spaces or on short climbs.
First models with Bosch Hub Line arrive in 2027
Bosch reported that the Hub Line should appear in the first production models starting in 2027, following the initial presentation of the technology to electric bicycle manufacturers.
Brands like Canyon, Gazelle, and Moustache have already introduced urban bicycles equipped with the new system, anticipating how the motor can be applied in different mobility proposals.
With this innovation, the German manufacturer ceases to operate only in its more traditional base of central motors and starts offering an alternative aimed at light, silent, and visually integrated urban e-bikes.
This move reinforces the sector’s pursuit of more discreet and practical electric bicycles for daily commuting, without giving up electric assistance, connectivity, and lower resistance when pedaling exceeds the motor’s operating limit.
