120mm of travel combined with the snappy 29” wheels for maximum traction on difficult terrain help the new BULLS Twenty9 E FS 3 RSi dominate any trail. The flatter approach angle of the e-29er 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 250W 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 by a 36V, 400 watt-hour battery that has a performance range of more than 105 miles on one charge. The Bulls Twenty9 E FS 3 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 turbo.

Motor: It utilize the Bosch 350 Watt Generation 2 Performance center-drive motor. The Bosch Drive Units are fitted with sensors for power, pedal rate and speed with a sampling rate of 1,000 readings per second using a modern 32-Bit processor, the motor seamlessly adjusts to your abilities. The Bosch Generation 2 motor systems are extremely responsive, giving a natural and smooth ride.

Battery: The Bulls Twenty9 E FS 3 RSi comes standard with Bosch’s shockproof PowerPack 400 system, a 400Wh lithium ion battery.

Riding Modes: The Bosch eSystem features a variety of drive modes to meet a wide range of needs, including the option to turn assist modes off. Turbo mode offers maximum power assistance with the motor contributing an additional 300% to the rider’s pedal power. Sport mode will give immediate power assist for sport riding and contributes 210%. Tour mode is optimal for long tours because of its consistent power and adds 120% to the rider’s efforts. Eco mode is the most effective drive mode to get maximum range by contributing 50% power. Lastly, it has the option to turn off all assist modes and the bike will perform as a normal bike would.

Display: The Bosch Intuvia LCD display has two main functions; to allow the rider to control drive parameters, and to display system information, including distance, time and speed. The control pad allows you to access all the computer and drive functions remotely, leaving your hands on the bar to maintain safety and security. To change motor settings while riding, simply push the large, glove friendly keys on the handlebar control pad. This ensures safety and stability, while still allowing you to control the motor for optimal performance.
