Haibike Alltrack 4 27.5" Electric Mountain Bike
The Haibike Alltrack 4 27.5" Electric Mountain Bike is an entry-level hardtail eMTB that gives you a powerful boost back up to the top of the hill, so you can have more fun with less effort. Pedalling assistance from the 250W Bosch Performance Line 250-watt motor and 500Wh PowerTube battery is supplied up to 15.5mph/25kph, and the system is neatly stored inside the frame.
The frame itself is constructed from tough aluminium, and this is paired with a 120mm travel SR Suntour fork, which soaks up big hits and bumps for a smoother, more controlled and comfortable ride. A mix of reliable components make up the 9-speed drivetrain and powerful hydraulic disc brakes create consistent stopping power in all conditions.
Haibike's Alltrack uses frame size-specific wheel sizes, and the small and medium offered here are fitted with 27.5" wheels for a good balance of rolling speed and lively handling.
