Bosch's New 120Nm Motor: Is Rohloff E-14 the Ultimate Transmission for High-Torque eBikes?

Bosch has officially turned up the power on its latest Performance Line CX motor, with selected models now capable of delivering up to 120Nm of torque and 750W of peak power.

As more brands push motor performance to new levels, one question keeps coming up: can traditional drivetrain systems cope with the extra power in the long term?

The additional acceleration is undeniably fun, but higher torque can also mean increased wear on chains, cassettes and drivetrain components. For riders covering serious mileage, carrying heavy loads or simply looking for the most durable setup possible, drivetrain choice has never been more important.

This is where Rohloff comes in.

At Fully Charged, we've long been fans of the Rohloff E-14 electronic hub gear system. With lightning-fast shifting, an enormous gear range, automatic shifting functionality and exceptional durability, it's the transmission we most commonly recommend for heavy-duty cargo bikes and riders who prioritise reliability above all else.

Not Every Bosch Bike Gets 120Nm

It's important to note that simply owning a bike equipped with Bosch's latest Performance Line CX motor does not automatically unlock the new 120Nm torque setting.

Manufacturers must individually approve each model before Bosch allows the higher power setting to be activated through the Bosch Flow App.

At the time of writing, only selected chain-driven models and Rohloff-equipped bikes with Gates Carbon Belt Drive systems have passed Bosch's testing requirements and can access the full 120Nm output.

That makes the Rohloff setup particularly interesting for riders looking to experience Bosch's maximum performance without compromising long-term durability.

Why Rohloff E-14 and Gates Belt Drive Stand Out

If you asked us to choose one drivetrain for a high-mileage cargo bike, year-round commuter or premium touring eBike, we'd pick Rohloff every time.

While derailleur systems have traditionally been the go-to choice for maximum power transfer, increased torque inevitably places greater stress on chains, cassettes and chainrings.

The Rohloff and belt drive combination offers several significant advantages:

• No chain stretch
• Dramatically reduced maintenance requirements
• No oily drivetrain to clean or maintain
• Near-silent operation
• Outstanding longevity in poor weather conditions
• Simple servicing with a recommended annual oil change or every 5,000km

For riders covering high mileage or using their bike daily, these benefits can make a substantial difference to long-term ownership costs.

Electronic Shifting Designed for Bosch Power

The Rohloff E-14 system integrates directly with Bosch's drive system, creating one of the most seamless riding experiences available.

Benefits include:

• Instant electronic gear changes
• Consistent shifting performance every time
• Automatic shifting modes available on selected models
• The ability to shift multiple gears with a single command
• Changing gear while stationary without pedalling
• Smoother shifting under heavy load

For cargo bike riders, commuters and anyone regularly stopping and starting in traffic, the ability to select the correct gear while stationary is a genuine game-changer.

120Nm Makes Climbing Easier Than Ever

Higher torque becomes most noticeable when riding at lower cadences and tackling steep gradients.

Combined with Bosch's latest support modes, the new 120Nm setting delivers exceptional climbing performance, particularly when carrying cargo, touring equipment or passengers.

This makes the system particularly appealing for:

• Steep UK hills
• Loaded touring adventures
• Commercial and family cargo bike applications
• Riders looking to reduce physical strain
• Anyone who prefers riding at a lower cadence

For many riders, it's less about achieving higher speeds and more about making challenging terrain feel effortless.

Why Riese & Müller Leads the Way

When it comes to premium Bosch-powered eBikes, few manufacturers embrace Rohloff technology quite like Riese & Müller.

As one of Germany's most respected eBike brands, Riese & Müller builds its bikes to order, allowing customers to choose from a range of drivetrain options depending on their riding style and priorities.

Depending on the model, options may include:

• Touring models with Shimano derailleur drivetrains
• Vario models with the Enviolo continuously variable transmission
