Niner E-Bike RLT E9 RDO 4-star 59CM Moss Electric Green

Our First E-Gravel, Reimagined

We’re calling it our first e-gravel bike, but it’s more like a pedal-powered SUV. Or an overland expedition vehicle. Or an urban ninja transit device. Our design details make this new bike equally at home across a range of environments, rolling over a broad swath of surfaces. Bosch powered, cargo capable, front suspension-ready, and flat-bar friendly, there’s almost no transportation task this chameleon can’t handle.

Bosch Performance for Speed

• The e-version of our vaunted RLT gravel bike goes far and it goes fast. The Bosch Performance Line Speed drive system propels a rider to 28 miles per hour (Performance Line CX and 25kph in the EU) with a 500wh battery for longer distances.
• Bosch leads the category with reliable motors that deliver smooth, lag-free pedal assist, backed by an unparalleled global service network.
• Our engineers wanted the battery to be integrated and yet easily externally removable. We solved this challenge through elegant RDO carbon construction.

Designed for Durability and Versatility

• FEA modeling and testing helped create a robust carbon structure that passes ISO mountain bike test standards.
• Bonded to a one-piece alloy motor mount for long-term reliability.
• Post-mount disc brake fitment and Boost spacing allow MTB drivetrain and brake compatibility.
• Fork is compatible with a FOX AX suspension fork and offers dropper post routing.
