The e-volution of gravel riding

Agility, comfort and durability, the holy trinity of gravel riding. Combined with a powerful Bosch motor, there are now more ways to escape the every day.

Powerful Bosch motor

Range 68.3 miles
Battery capacity 500 Wh
Assist up to 28 MPH
Max torque 85 Nm

The Grail:ON lets you take on the longest rides, steepest climbs, and biggest adventures.

Equipped with Bosch’s proven Performance Line Speed drive, the Grail:ON more than triples (340%) your pedaling force and provides a massive 85 NM of peak torque, for instant power when you need it most.

Rides like a gravel bike

The Grail:ON has the same stable-yet-agile ride as the Grail, due to its similar frame geometry. And by placing the motor low down, you get even more stability.

Most relaxed riding position

The Grail:ON has a more upright riding position than the Grail, reducing back and shoulder pressure for more comfort.

Lower centre of gravity

Positioning the motor low down creates a low centre of gravity. This increases stability on fast descents and steep climbs.

7 sizes, consistent feel

With a huge 2XS-2XL size range, riders from 156-200+ cm can get their perfect fit. Smaller 650B wheels in sizes 2XS and S ensure consistent handling for all riders.

Comfort designed into every touch point

Working with the unique properties of carbon we’ve designed e-gravel touch points that flex with the road, dampening road chatter, and working with your terrain to help you enjoy every aspect of the ride.

The Double Decker Bar

Ergonomic design and shock-absorbing carbon construction unite to create the ultimate in comfort.

The Flex Area uses carbon’s elastic properties to significantly absorb vibrations. 4 distinct hand positions keep your back and shoulders fresh.

E-gravel wheels

DT Swiss HG wheels are designed for the demands of e-gravel.

Stainless-steel spokes and strengthened hubs with steel parts withstand the motor’s increased torque over years of use.

Combined with 50 mm tyres to float over the rough stuff.

Shock-damping seatposts

The Grail:ON's carbon seatpost flexes to absorb vibration while keeping a consistent tilt, so damping is effective yet unobtrusive.

For more comfort, the clamp is located low in the seat tube, increasing the seatpost’s bending length.

Durable, E-gravel specific components

Built to withstand the additional force put out by the Bosch motor, the Grail:ON greater stopping power, powerful hubs and clever extras to keep you clean on your commute and dry on your adventure.

Mess-free riding

We’ve created a custom set of mudguards for the Grail:ON. They require no mechanical skills to fit. To stop the front mudguard brushing against your foot, the frame has extra toe clearance.
