Gravel Plus E-Bike. We combined our finest carbon gravel bike chassis with the best motor system from Bosch to create a powerful, go-anywhere, do-anything adventure machine with almost unreal riding qualities.
KingPin Suspension. Revolutionary, super-light suspension that lets you ride harder on dirt and more smoothly on pavement. Better control. Better traction. Better comfort. Nothing sacrificed.
Proportional Response Construction. Suspension and overall frame ride-feel is custom tuned by size, using different carbon layup and different tube dimensions, so each size is dialed for the rider. Just get on and go.
Dialed Endurance Fit. Offers a perfectly balanced riding position: upright enough for comfort over the long haul and control when tackling technical off-road terrain, yet still low and forward enough for speedy efficiency.
Multi-Function, Multi-Purpose. The e-gravel bike that has everything. Big clearance for big tires. Tons of gear and storage mounts. Internal dropper post compatibility. Refined geometry and a confident rider position all come together to create a machine that’s stable, composed and laugh-out-loud enjoyable to ride.Occasionally, without notice, manufacturers change product design and/or specifications.
