Haibikes entry-level Electric Mountain Bike. This 500wh, medium-length Cross Country hardtail will open up the trail and take you places where you never thought you could go. Whether it's your local trail centre, or blasting around the fells and cycle tracks, its light and fast perfect to get you into the e-bike market.

At the heart of the Hardseven 4.0 is the 6061 aluminium frame paired with a 120mm Suntour fork. Simplicity combines with a function means the Hardseven does exactly what it says on the tin. The 27.5 inch (650b) wheels roll fast whilst having a slightly more responsive feel than a 29er.

Brakes and Gears

Simplicity is at the core of the Sduro Hardseven, this fits with the gear choice, Haibike has chosen Shimanos Deore M6000 groupset matched with an 11-42t cassette, perfect for flying around the trails. Once you’ve experienced the pleasures of electric assist, you’ll need something to stop you, in this case, Tektros M275 brakes offer excellent stopping power.

Motor and Battery

The Bosch Performance CX has been specially optimized for sporty use. The motor delivers a constant maximum torque of up to 75 Nm up even to a high-speed range.

The motor offers an impressive maximum torque of 75 Nm. The “Direct Flow” technique also guarantees powerful support in the lower cadence levels. Trail Control offers a dynamic power management system, that allows the rider to choose the optimum support level (50-300%) for the terrain they are riding, their riding style, and the distance they are looking to cover. “Shift detection” protects your chain by cutting off the torque from the motor during shifting for smooth gear changes.

The Intuvia display tells the rider: actual, average and maximum speed, day trip and total distance, the time, trip time and total operating time of the bike, and motor performance. The remote control is located on the left of the handlebars and all display features and support modes can be selected safely while driving without taking your hands off the handlebars. The stable display base ensures a secure fit even under tough conditions.

The battery is a Bosch 500wh battery. Technically the battery has a range of 30-80 assist miles, the latter being a best-case scenario. In our experience, for general use with mixed terrain, you can comfortably expect 30-45miles
