Niner RIP e9

RIP 9 RDO 29 Mountain Bike

As the name implies, or at least infers, Niner was a bike brand founded on the concept of designing 29” wheel specific bikes. Since their introduction in 2005, Niner has set about to perfect the design and performance of their bikes dedicated to the big wheel size design which has helped them stay at the front of the popularity curve as far as 29ers go.

The Colorado-based brand has always prided itself catering to every category of off-road rider. From hardtail and full suspension trail and gravel bikes and now e-bikes. When the demand for e-bikes came along the same mentality of access for all remained. Niner believes if a bike gets you riding off-road it’s a positive thing.

For their initial MTB offering, Niner rolled out two versions of an all-mountain style full suspension e-bike; the RIPe9 with 150mm of travel and the downhill-oriented, $6295 WFO e9 with 180mm of travel and surprisingly, a 29”/27.5” mixed wheel combo.

The aluminum frame has internally routed cables and connects the motor mount with the upper and lower shock mount for maximum rigidity. The grey and black color scheme with multicolored lettering is pretty unique as well. For the tweakers and tuners of the world, you can adjust the frame’s geometry by changing the position of the trunnion mount shock.

One plus to this frame is a water bottle mount which seems to be hit and miss with many of the e-MTBs we have encountered.


The pedal assist system for the RIPe9 is the new 4th generation Bosch Performance CX line with their Purion display. The larger 625wh battery is integrated in the frame with a charge port near the bottom of the frame. Niner rates the parts spec as one of their 3 star builds which means most of the components are in the mid to upper level category.
