A little history

Brose is no newcomer to precision engineering. With over 110 years of experience, this German company has positioned itself in recent years as a high-end player in the e-bike market. Today, more than 30 bicycle brands rely on their technology. Their philosophy is simple and ambitious: a quiet, powerful, and compact motor, so that the bike remains a bike in terms of feel.

What makes Brose so special?

The belt drive is remarkably quiet.

While most motors use gears that inevitably produce noise, Brose has chosen a different path. At the heart of their mid-drive motors is a carbon fiber-reinforced belt. The result is a transmission so quiet that you sometimes forget you're riding an electric bike. No buzzing when accelerating, no vibrations in the pedals. Just... silence.

Pedal without resistance, even with an empty battery

You know that feeling: when the battery is empty, your e-bike suddenly feels as heavy as lead. With Brose, this problem disappears. Thanks to Dual Freewheel Technology, the motor and transmission are completely decoupled when the assistance is switched off. The bike then behaves like a conventional bike, light and smooth. A seemingly minor detail, but one that changes everything.

Smart sensors for a natural feel

The difference is in the details. Brose uses an advanced sensor system that continuously measures your pedaling power and cadence. Pedal harder? The assistance increases. The feeling is intuitive, almost telepathic. The sporty models go even further with Flex Power mode, which provides up to 30% more power at high cadences.

Aluminum or magnesium: the choice is yours

Brose offers two platforms. The aluminum version is renowned for its flexibility: the motor can be mounted at 360 degrees around the bottom bracket. For those looking to reduce weight, the magnesium variant (Mag models) is the ideal solution: 500 g lighter and 15% more compact. Perfect for cyclists who are mindful of every gram.

Strengths and weaknesses

Why choose Brose?

• Unmatched quietness: belt drive makes it the quietest motor in its class.

• Natural driving feel: the assistance gives the impression of having ten times the power.

• No resistance when pedaling: even with an empty battery, the bike remains easy to ride.

• Sustainable commitment: Brose is the first manufacturer to offer a reconditioning program, saving 21 kg of CO₂ per motor.

What to look out for

• Dependence on the reseller network: software updates and upgrades must be performed by a certified reseller.

• Upgrade costs: upgrading from 75 Nm to 90 Nm is possible, but incurs an additional charge.

Who is Brose suitable for?

Whether you're looking for a city bike for your daily commuteor a reliable touring bike for long rides, or an powerful e-MTB for demanding terrain, there is a Brose motor to suit your riding style.

Brands such as Hercules (with models offering up to 90 Nm and 720 Wh batteries), as well as many other manufacturers, are deliberately choosing Brose. The reason is simple: this combination of exceptional quietness, natural feel, and compact design remains difficult to match.

Conclusion

Brose demonstrates that German engineering and e-bike technology are a perfect match. An ideal choice for cyclists looking for quality, quietness, and an authentic riding experience.
