Robust and reliable, the Haibike HardSeven 4 Electric Mountain Bike is a perfect entrance into the world of assisted cycling. With agile geometry and a powerful Bosch Performance Line motor, it excels on singletrack, cycle paths and more, offering excellent performance for its price point.
The 27.5” wheels are quick to accelerate and easy to manoeuvre, and the reliable Shimano drivetrain provides a wide range of gears and crisp shifting. A Suntour XCM32 suspension fork reduces fatigue on choppy terrain, and the Bosch PowerTube 400Wh battery provides a wide range for mid-length rides.
