The "HardSeven 6" model from Haibike, released in 2024, is a versatile e-mountain bike characterised by its robust construction and high-performance specifications. The frame is made from 6061 aluminium and is fitted with an X-12 (1.00) x 148 mm thru-axle and a post-mount disc brake. The bike’s maximum load capacity is 120 kg, making it suitable for heavier riders too.
Braking performance is provided by Tektro M275 brakes with 180mm discs, operated by the matching aluminium Tektro M275 brake levers. The drivetrain is a Shimano Deore M4100 10-speed system, controlled by Shimano Deore M4120 trigger shifters. This combination enables precise and reliable gear changes across various types of terrain.
The HardSeven 6’s fork is an SR Suntour XCM34 NLO DS with steel spring/oil damping, 120mm of travel and an aluminium steerer tube that is tapered from 1 1/8 to 1 1/2 inches. The fork is also fitted with a 15 x 110 mm Boost thru-axle, which provides additional stability. The pedals are aluminium freeride pedals and are fitted with reflectors.
The crankset is made of steel with a 38-tooth chainring, whilst the Shimano M4100 cassette, with 11–42 teeth, provides a wide gear range. Power is transmitted via a KMC e10S chain. The handlebars are XLC Topflat with a width of 740 mm, complemented by XLC MTB grips and an XLC aluminium A-Head stem. The headset is A-Head Tapered.
The rims are Rodi Tryp 30, eyeleted and constructed as hollow-section aluminium rims. The tyres are WTB Ranger Comp, sized 65-584. The spokes are Sapim Leader, and both the front and rear hubs are made of aluminium and are supplied by Haibike.
The saddle is an XLC MTB model and sits on an XLC Patent seatpost with a diameter of 31.6 mm, also made of aluminium.
At the heart of the e-mountain bike is the Yamaha PW-ST System motor, delivering 250W of power and 70Nm of torque, which propels the bike to a maximum speed of 25 km/h. The battery is an InTube model with a capacity of 630 Wh, providing sufficient power for extended rides. The display is a Yamaha Side Switch, which clearly shows all relevant information. The battery is charged using a 4A fast charger.
The Haibike HardSeven 6 is priced at €3,099, making it an attractive choice for riders looking for a powerful and well-equipped e-mountain bike.
