The Merida eBig Nine 300 SE makes e-biking simple, enjoyable, and accessible. It’s built around a Lite hydroformed 6066 aluminium frame, designed for a stable and comfortable ride whether you’re tackling gravel paths, forest tracks, or daily rides through town. The frame features internal cable routing, a tapered head tube for front-end stiffness, and mounts for mudguards and a kickstand — ready to adapt to commuting or leisure duties.
Power comes from the refined Shimano EP5 motor, delivering up to 60 Nm of torque for smooth, natural assistance. It’s paired with a 504 Wh externally mounted battery, offering a practical setup that’s easy to remove and charge. Together, they provide reliable power and range for everyday riding without unnecessary complexity.
The Suntour XCM34 Boost Air fork gives 100 mm of travel, smoothing out rough terrain and trail chatter, while 29" Merida Comp TK wheels and Kenda Booster tyres add stability and traction across mixed surfaces. The Shimano Altus 8-speed drivetrain offers dependable shifting and a broad gear range to handle hills and open trails alike.
Stopping power is supplied by Shimano MT200 hydraulic disc brakes, providing consistent braking in all weather conditions. Finishing touches like the Merida Expert saddle and aluminium finishing kit complete a bike that feels solid, confidence-inspiring and easy to live with.
Whether you’re new to e-bikes or looking for a reliable electric hardtail to broaden your riding horizons, the eBig Nine 300 SE delivers quality, comfort, and capability in a package that’s built to last.
