It's right for you if...

You’re sold on the e-bike revolution and want the capability and versatility of a mountain bike at a price that doesn’t resemble the car you’re trying to use less. You want bigger, better off-road adventures, and know that an e-MTB with the latest user-friendly tech is the best way to get them.

The tech you get

A tough yet refined aluminium frame that fully encases a long-range 500 Wh battery for sleek looks, a Bosch Performance CX (250 W, 85 Nm) motor that assists up to 20 mph or 32 km/h, a Bosch Purion controller, a 1×10 Shimano drive train, an SR Suntour fork with lockout and hydraulic disc brakes. Plus, Smart Wheel Sizing means riders of every size get a great fit – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.

The final word

Our most affordable electric mountain bike comes with the same powerful Bosch motor and intuitive controller as our most expensive e-bikes, with a smaller battery and parts chosen to give you great value.

Features

Will my bike have a curved top tube?

Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Bosch Performance Line CX motor

The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

Removable Integrated Battery

RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.

What is the range?

To see how far you can ride your electric mountain bike on a single charge, check out Bosch’s range calculator. We’ve auto-filled the variables for this bike model and the average rider, but you can make adjustments to get your most accurate estimate.
