New motor: Brose Drive S Mag – More powerful, lighter, smaller

Motor specialist Brose presents their new high-end motor: magnesium housing, new electronics and special sensors provide more power with less weight and smaller dimensions. Also, there are three new remotes and displays available across the range from minimalist to all the information you could ever need.

So far, the Brose Drive S convinced us above all with its natural riding feel and the non-existent pedalling resistance. However, it’s large dimensions have previously made life difficult for many bike manufacturers. This is set to change with the new Drive S Mag. With the new magnesium housing, the motor has shrunk by 15 % and should also be about 500 g lighter. Despite the diet, the new motor is more powerful than its aluminium equivalent, providing 410% support instead of 380%. The torque remains unchanged at 90 Nm but should now be usable over a wider cadence range. On the trail, this means that the motor’s full power is available even at a lower cadence.

Gone on diet: the magnesium version of the Brose Drive S has slimmed down significantly

New riding mode – Flex Power Mode

Besides the new housing, the Drive S Mag has also been equipped with new boards and chips, making it easier to combine the sensors inside. The result is a new riding mode at the highest support level. In Flex Power Mode, power delivery is controlled according to cadence and pedal force. As a result, Brose promises a significantly faster response from a standing start and thus significantly quicker when pulling away. Due to the hardware requirements, Flex Power Mode is only available in the new Drive S Mag.

New Remotes and Displays

Brose has released three new remote and display options. Specialized has been using Brose motors with a minimalist display-less remote on several of their models for some time now. A similar minimalist remote control is now available directly from Brose. The charge level and speed are indicated by small LEDs. It can also be coupled to a large display mounted centrally on the handlebars. In addition to the power levels, the colour display can show a great deal of additional information simultaneously.

For those who can’t decide between minimalism and full information, there is a combination display with an integrated remote for the left thumb.

Conclusion

The Drive S Mag takes everything we already liked about the “old” aluminium Drive S and makes it even better. It’s smaller, lighter and more powerful. Finally, there is a minimalist remote without a display, we like! Tests will show whether the Drive S Mag keeps what it promises on paper. We can’t wait.

Further information on Brose motors

In addition to high-end eMTB motors, Brose has also turned their attention to the touring and trekking segment. The torque of the Drive T has been reduced from 90 Nm to 70 Nm. Instead it will provide its full torque over a particularly wide cadence range.
The dealer and service network has also been expanded. New diagnostic tools for certified dealers and service centres should make repairs, services and updates a lot easier.
