TWENTY9 E FS 3 RSI

DESCRIPTION

120mm of travel combined with the snappy 29” wheels for maximum traction on difficult terrain help the new BULLS Twenty9 E FS RSi dominate any trail. The flatter approach angle of the e29er MTB rolls over obstacles such as rocks and roots with ease. For larger strokes the RockShox Reba RL suspension gets to show off its performance. A remote lockout is placed on the bars to quickly alternate the fork between rigid and an open position. Through the use of a 12mm thru-axle the 29” inch wheels receive even more rigidity, noticeable advantages are better cornering and stiffer handling. The Shimano Deore brakes ensure smooth braking in even the most extreme conditions. An 11-speed rear Shimano XT set-up gives you plenty of gear range no matter where you’re riding.

A mid-engine design with Bosch’s CX Performance Line 350W leaves the motor tucked away in the bottom bracket shell for an ideal center of gravity. With its small drive pinion Bosch engines guarantee the best performance. An innovative chain guide concept is able to reduce the drive influences to the suspension. The design not only helps the kinematics of the rear swing-arm but also prevents the chain from hitting the chainstay.

When going across rocky terrain a Skid Plate is used which to help protect the motor. The exclusive protection prevents all types of damage caused by stone rock chipping and bouncing. The power is supplied with an option of a 400 watt-hour or 500 watt-hour battery that has a performance range of more than 105 miles or 134 miles on one charge. The Twenty9 E FS RSi has a charge time of 3.5 hours making it one of the fastest on the market. You can alternate the power output from 4 different modes, Eco, Tour, Sport and

technology-image Bosch Performance CX line thrills trail enthusiasts with a torque of up to 75Nm and powerful assistance up to 300%
technology-image The 11-speed drivetrain with 11-gear cassette has proved to improve efficiency and ultimately power
technology-image Higher frames require longer chain stays. The results are a much improved climbing capacity, which is relevant in large frames. After all, the center of gravity clearly shifts backwards with a taller rider, specifically during the climb. Taller riders also need more space as they usually have longer feet and for the longer cranks to avoid touching the chain stays with their heels.
technology-image This is semi-integrated headset with an inner diameter of 1 1/8u201d at the top and 1 u00bdu201d at the bottom. This ensures best riding stability and excellent control head stiffness. The biggest shaft results in stiffer fork and frame as riding forces are spread more evenly thanks to a thicker head tube.
technology-image BULLS eBikes are protected by Skid Plate, a shield developed exclusively for Bosch-equipped off-road eBikes which guarantees an action-packed ride on even the most extreme slopes. Like the underbody protection for off-road vehicles, the Skid Plate protects BULLS eBikes from direct impact damage
technology-image Shimanou2019s Shadow Plus clutch mechanism prevents the lower arm of the derailleur from pivoting forward as the chain is kept under considerably more tension. The benefits are many: less chain slap, fewer dropped chains, more stable and accurate shifting over rough terrain and ultimately a much better and quieter ride.
technology-image The main advantages of the thru-axle system are stiffness and strength, which add together to a safer bike. It has a clear advantage on disc brakes over the traditional quick release as it allows for easier and more precise wheel mount/dismount operation.
technology-image Tubeless clearly decreases rolling resistance of the wheels while reducing the overall weight of the bicycle. In addition, there is some extra grip and comfort when riding at a low pressure.
technology-image Sandwich construction and additional cooling fins reduce the heat development and increases the brake performance and results in lower wear.
technology-image Internally routed shifting and braking cables ensure a clean and elegant look while ensuring a better protection to all important cables.
technology-image The travel of front suspension is 120mm.
technology-image Full suspension bike with a rear shock of 120mm travel.
