The E-STREAM EVO AM 4 e-bike is equipped with a high-quality FOX chassis, a powerful Brose S Mag drive unit, a light carbon frame and a BLOKS 14d display. The E-Stream EVO AM4 e-bike is ready for a wild mountain ride in difficult terrain and for a quiet ride on a bike path. The 150 mm suspension offers a great driving experience on demanding routes, while ensuring excellent stability and comfort. Schwalbe Nobby Nic 27.5 x 2.80 tyres provide perfect adhesion.

Thanks to the central motor, fully integrated battery and great geometry, the e-bike is perfectly and optimally balanced. The shorter wheelbase ensures excellent maneuverability and dexterity even on narrow routes. The combination of an extended upper tube and a shorter handlebar stem also improves the position of the seat. In conjunction with a balanced steering angle and telescopic seatpost, every downhill terrain becomes a unique experience.
