Niner is showing-off its new electric-assist gravel bike called the RLT e9 RDO, the third model in the company’s range of Bosch-powered e-bikes.
In the case of the RLT e9 RDO however, it’s the first such e-gravel bike from Niner, which features Bosch’s fourth-generation Performance Line Speed drive system that’s equipped with a 500Wh battery to deliver 85Nm of torque and a top speed of 28mph with an average range of 30 miles between charges, while the PowerTube battery is mounted externally for easy removal.
The RLT e9 RDO’s frame and fork are made with Niner’s RDO (Race Day Optimized) carbon fiber, housing the electric-drive system in the lower bottom bracket area, while Bosch’s Purion display is mounted in front of the stem to convey essential ride information.
“This design presented structural engineering challenges,” Niner stated. “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 one-piece alloy motor mount, this machine is ready to go the distance for years to come.”
Other features that highlight the RLT e9 RDO are a Shimano GRX 1x groupset, a Praxis aluminum crankset, Stan’s NoTubes Arch tubeless wheelset, dropper seatpost routing, post-mount disc brakes, a Boost hub and the ability to swap out drop bars for a flat handlebar, along with requisite bottom bracket spacing to fit MTB wheels and drivetrain components, as well as accommodations for a 50mm suspension fork.
Additionally, the RLT e9 RDO can accommodate tires up to 50mm for both 700c and 650 size wheels, along with provisions for fenders on the frame and fork, as well as two water bottle mounts inside the front triangle for ample, easy to reach hydration.
All in, Niner says RLT e9 RDO weighs in at 39 pounds (18kkg) in a size 53 that will retail for $5,695 beginning on October 15.
