You don't need to spend a fortune to enjoy the world of e-biking. Our budget-focused eBIG.NINE 300 SE models deliver a quality ride thanks to an aluminium frame and powerful but refined Shimano EP5 drive unit, but with the convenience of an easily removable externally mounted 504 Wh battery. Powerful, all-weather Shimano hydraulic disc brakes are on hand to keep control and the tough, long-lasting CUES drivetrain offers plenty of gearing for off-road adventures or the city streets.
Arguably the most versatile e-bike in our range, the tried and tested eBIG.NINE embodies the perfect balance of day-to-day usability and sporty leisure activity. It's a bike that can handle serious off-road riding but can also handle the commute to work with ease - especially if you want to have some fun on the way. The high-quality aluminium frame integrates a choice of 630 or 750 Wh battery sleekly into the downtube, with a more economical frame featuring semi-integrated 504 Wh battery on some models. All feature powerful and smooth Shimano drive units that will power you up any hill. Ready to be equipped with mudguards and even a side stand (or available as the EQ fully equipped version), the eBIG.NINE will help you make the most of any situation.
