Bulls Sonic EVA AM-SX 1 with Bosch PowerMore 250Wh is a lightweight full-suspension e-bike for trail and mountain riding on 29" wheels. It belongs to the performance class of light e-bikes with a mid-drive motor and an emphasis on low weight. In practice, it targets riders who are looking for the right balance of power and handling in technical terrain.
We also add a PowerMore 250 Wh extender to the e-bike at no extra charge, which increases range while preserving 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 a Diamond frame design, intended for all-day trail use. The suspension is built around a fork with 140 mm of travel and a rear shock with 130 mm of travel. The ACROS AIF-531 1.5 headset supports front-end stiffness under braking and through corners. The bike is available in sizes S, M, and L.
Drivetrain: Shifting is handled by a Shimano Deore SL-M6100 12-speed shifter and a Shimano Deore RD-M6100 rear derailleur. The Shimano Deore CS-M6100 cassette has a 10–51T range.
Brakes: The hydraulic disc brakes use a Shimano BR-MT420 caliper up front. The rotors are 203 mm in diameter both front and rear.
Wheels and tires: The wheelset is MAVIC E-Crossride 1 CL MS in 29". Schwalbe Wicked Will Performance and Nobby Nic Performance tires are sized 62-622 and 60-622.
Cockpit: The handlebars are BULLS riserbar, and the Poligon stem is 45 mm long. The Limotec Alpha 1UH dropper post has a 31.6 mm diameter and 150 mm of travel.
The combination of 29" wheels and 140/130 mm travel pushes the bike’s behavior toward trail use, with an emphasis on stability in rough terrain. The Bosch Performance Line SX mid-drive motor with 55 Nm of torque supports smooth power delivery on technical climbs. The wide 10–51T cassette range helps maintain cadence even at slower speeds on steeper ascents. The 203 mm rotors increase braking reserves on longer descents and with the higher weight of an e-bike.
The Bulls Sonic EVA AM-SX 1 is designed for experienced riders who want a lighter full-suspension e-bike for trails, mountain climbs, and longer off-road adventures. Thanks to the dropper post and trail-focused travel, it suits riding in technical sections as well as on natural singletrack. Compared with traditional heavier e-bikes with higher torque, it prioritizes lower weight and a more natural ride feel.
