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.
What’s not so obvious are the details, starting with our RDO carbon construction. Our engineers wanted the battery to be integrated and yet easily externally removable for the utmost flexibility when recharging. However, this design presents engineering challenges that we solved in elegant fashion.
Designed for Durability and Versatility
Using FEA modeling and extensive testing, lead engineer George Parry built a robust carbon backbone structure to withstand the roughest roads imaginable. In fact, the RLT e9 RDO passes ISO mountain bike test standards. Bonded to a 1-piece alloy motor mount, this machine is ready to go the distance for years to come.
Subtle design features add incredible versatility. Post-mount disc brake fitment makes it easy to change to a flat handlebar with mountain bike brakes. Likewise, our intentional inclusion of Boost hub and crankset spacing allows the rider interchangeability with mountain bike drivetrain parts. And the all-new RLT e9 RDO carbon fork is the same length as a FOX AX suspension fork. There’s even routing for a dropper seatpost.
Ride Locally or Around the Globe
For a dose of rugged utility, Niner’s custom, integrated racks are available to carry supplies for a trip to the office or a ride around the world. Clearance for comfortable 50c tires and fitment for fenders round out this chameleon-like gravel bike.
If you can dream it, the RLT e9 RDO can do it. Gravel roads around the globe beckon this bike, as do social trails through town, bike paths, and even urban alleyways. Adventure waits for you, but don’t keep it waiting
