There is currently no Bosch e-bike rear drive, but a development is conceivable. A Bosch rear motor can offer many advantages:

Advantages of a rear motor on an e-bike:

1. Better traction: Since the weight of the engine is shifted to the rear wheel, this improves traction, especially on slippery or uneven surfaces.
2. Less wear: The drive train is subjected to less stress because the motor drives the rear wheel directly, which leads to less wear on the chain and sprocket.
3. Free choice of gears: A rear motor allows the use of a hub gear , which is often not possible with mid-engines.
4. Aesthetics and balance: The rear motor allows for a clean and sleek frame design, as there is no large motor in the middle. This can result in a more visually appealing and better balanced bike.

Differences to the mid-engine:

1. Weight distribution: A mid-engine has central weight distribution, resulting in a lower center of gravity and better handling, especially on technical rides and trails. A rear-engine shifts the weight to the rear wheel.
2. Power transmission: Mid-engines transmit power to the rear wheel via the chain, which can lead to greater wear on the chain and cassette. Rear-engines drive the wheel directly, thus avoiding this additional wear.
3. Maintenance: Mid-mounted motors can be more complex to maintain because they are integrated into the frame and put stress on the chain. Rear-mounted motors are often easier to maintain and replace.
4. Efficiency: Mid-drive motors can be more efficient because they can optimally support human power through gear shifting, resulting in better energy utilization. Rear-drive motors provide constant support regardless of gear selection.
5. Ride feel: Mid-engines offer a more natural ride feel because they directly amplify pedal power. Rear-engines can sometimes give a less direct ride feel because the assistance is provided at the rear wheel.

A Bosch rear drive can combine the benefits of a powerful rear drive with the advanced technology and reliability that Bosch is known for, and may represent an attractive option in the future for e-bike riders looking for a powerful and low-maintenance drive solution.
