Bulls Sonic Eva SX 1 400Wh Bosch E-Bike
The Bulls Sonic Eva SX 1 utilizes a lightweight aluminum hardtail frame designed for female riders seeking a nimble and responsive e-MTB for cross-country use. Powered by the Bosch Performance Line SX motor, it delivers 55Nm of torque in a package that emphasizes low weight and natural pedaling resistance. Suspension hardware consists of a Bulls Lytro 34 Air fork with 120mm of travel, providing plush damping and easy setup. Braking functions via Shimano MT200 hydraulic disc brakes, providing reliable stopping power for light to moderate trail riding. The frame features the characteristic Sonic lateral battery removal for ease of handling.
The Bulls Sonic Eva SX 1 battery provides 400Wh of capacity through the Bosch CompactTube 400, integrated into a slim and elegant downtube. A handlebar-mounted Bosch Purion 200 display visualizes all essential data including speed, range, and battery level in a high-resolution color format. Electronic integration connects the motor with a Shimano CUES U6000 10-speed drivetrain, ensuring smooth and reliable gear changes. The bike is equipped with 29-inch wheels for high-speed stability and better rollover performance on rough paths. Internal cable management maintains the frame’s sleek aesthetic. Integrated sensors monitor torque and cadence hundreds of times per second to ensure intuitive motor assistance.
