BULLS Sonic AM-SX 1

The BULLS Sonic AM-SX 1 is a lightweight all-mountain/trail eMTB with a carbon frame

A lightweight full-suspension all-mountain e-bike that combines the natural riding feel of a classic mountain bike with the benefits of a modern, lightweight Bosch drive system. The Sonic E-Power Chassis carbon frame, 140 mm of front travel and 130 mm of rear travel, and 29" wheels create the ideal combination of climbing efficiency, stability on descents, and playful handling on technical trails. Thanks to its low weight, the bike is exceptionally agile and delivers an authentic riding experience.

Power comes from the compact Bosch Performance Line SX motor with 55 Nm of torque, which offers natural and smooth pedaling assistance. The integrated 400 Wh Bosch CompactTube battery helps keep the bike’s weight low and can be expanded with an additional 250 Wh Bosch PowerMore battery for longer rides. The Bosch Smart System allows connection to the eBike Flow app, customization of riding modes, and wireless updates.

Comfort and confidence on the trail are ensured by the BULLS Lytro 34 SL air fork with 140 mm of travel and rear suspension with 130 mm of travel, which effectively absorbs bumps and ensures excellent traction. Precise shifting is handled by the SHIMANO Deore RD-M6100 1×12 with a wide gear range, and hydraulic disc brakes provide reliable stopping power even on challenging descents. The Schwalbe Nobby Nic tires on the 29" wheels offer excellent grip and confidence on both dry and wet surfaces.

The bike also comes equipped with a LIMOTEC dropper seatpost, which allows you to quickly lower the saddle during technical descents and increases control over the bike. Its well-thought-out geometry, high-quality components, and lightweight Bosch SX drive system make the Sonic AM-SX 1 the ideal choice for sporty trail riding and long mountain excursions, where you’ll especially appreciate its natural riding feel and high maneuverability.

The BULLS Sonic AM-SX 1 is ideal for riders looking for a lightweight e-MTB with a modern Bosch Performance Line SX drive, high-quality suspension, and sporty geometry. It offers the perfect balance of performance, low weight, and maneuverability for challenging trails and all-day adventures in the mountains.
