More Info

The dedication to exploration is a mission and there’s no better tool for the job than the TrailSport FS. A rear hub electric motor with a massive lithium ion battery and twin air shock suspension turns a regular bike into a journey you’ll never forget. It allows you to tap into 8-speed gears making hills a small hurdle and forge a path through any obstacle, whether it’s roots, rocks, mud or even a mountain. You’ll never know what you can accomplish until you try.

The rugged aluminum alloy frame uses a partially integrated battery pack capable of delivering over 50 miles per charge using pedal assist or around 20 miles on throttle-only mode. The Sport version features fast-rolling mountain bike style tires in the 27.5" x 3" size for improved efficiency on roads, gravel and trails making it a perfect choice for the ultimate commuter. The full suspension frame steps up the comfort and control over our very popular All Terrain HT model and helps give riders the most enjoyment possible out of their experience. Powered by the same 750w Bafang rear hub motor as many of our other best selling bikes, the Sport FS inspires confidence in the rider with it’s incredible stability and more nimble wheel and tire combination.
