Bulls Sonic SX 2 with the Bosch PowerMore 250 Wh is a full-suspension lightweight e-bike designed for sporty mountain riding off-road. It is built around the Bosch Performance Line SX system and a low overall weight for punchy acceleration. This model targets the higher sport category, where the key factors are drivetrain performance, suspension, and wheel spec.
We also include the PowerMore 250 Wh extender with the e-bike, which allows you to increase range while keeping what the e-bike does best - low weight. Range increases by more than 60% and weight goes up by 1.6 kg.
The frame is made from a carbon composite in the Diamond design and is engineered for low weight and efficient power transfer when pedaling. The ACROS AIF-531 1.5 headset supports front-end stiffness and precise tracking. Front suspension is handled by a RockShox SID fork with 120 mm of travel, which suits fast trail and marathon use. The integrated Bosch CompactTube 400 battery keeps the look clean and protects the аккумулятор during off-road riding.
Drivetrain: SRAM EC AXS Rocker shifting works with 12 gears and wireless control. The SRAM GX Eagle AXS Transmission rear derailleur uses a SRAM GX Eagle T-Type 10-52T cassette.
Brakes: TRP C2.3RX TRAIL hydraulic disc brakes with SLATE calipers are designed for trail loads. The rotors measure 203 mm up front and 180 mm at the rear.
Wheels and tires: MAVIC Crossmax XL S wheelset is built for 29" off-road use. Schwalbe Nobby Nic Performance Folding tires are sized 29 x 2.40 (62-622).
Cockpit: RUMBLE Altimate handlebars are paired with a Rumble Altimate stem for a sporty riding position. The LIMOTEC Alpha Series A1-UH dropper post has 125 mm of travel, and the saddle is a Prologo Proxim 400 wide.
The combination of the carbon frame and MAVIC wheelset supports stiffness under acceleration and precise line-holding. The Bosch Performance Line SX motor with 55 Nm delivers smooth assistance up to 25 km/h, which fits fast trail riding. The RockShox SID fork with 120 mm of travel stabilizes the front end in rough terrain and under braking. Wide 29 x 2.40 tires increase traction on roots and rocks, especially on climbs.
This bike is intended for experienced riders who want a lighter full-suspension e-bike for sporty trails and mountain rides. It’s well suited to hilly terrain, where you’ll appreciate the quick motor response and low weight. Compared to heavier e-bikes with higher torque, it focuses on pedaling efficiency and handling.
