a 12 speed SRAM SX derailleur with a 50t climbing gear and a 1x 36t chainring. The RIPe9 rides on 29” tubeless-ready Stan’s Flow rims with a mixed pair of a 2.5” Maxxis Aggressor tire in the rear, and a Minion DHF in the front. Slowing the 50-pound bike down are a pair of SRAM Guide brakes with 203mm rotors.
Niner couldn’t have picked a more perfect time to get into e-bikes especially when you consider the current e-bike boom which is as much the result of the Covid-19 crisis as well as the ever-growing popularity mass media publicity that e-bikes have been enjoying.
Only helping matters has been the timing of Bosch releasing their new motor and bigger battery. Adding to all that, Niner has made an e-bike that really fits a sweet spot in the market. The ergonomics feel really nice, and the added wheel size of the 29ers make for a really smooth ride all around. The price is right in the ballpark of what you would expect for a bike with this ride quality and component build.
When we first got the RIPe9 out of the box our first thought was that the down tube looked extra square and big. Although we quickly realized the new 625wh battery takes up a bit more room and Niner obviously did their homework making an extremely balanced machine.
One trouble spot is the placement of the charge port which is placed right on the inside of the cranks which could cause damage if the cranks are rotated when charging. Luckily, the Bosch chargers are really sturdy and this shouldn’t be a deal-breaker. The frame comes with a lifetime warranty.

Mountain Bike Action is a monthly magazine devoted to all things mountain biking (yes, that’s 12 times a year because we never take a month off of mountain biking). It has been around since 1986 and we’re still having fun.
