# Best electric mountain bikes in the UK Source: https://pedalandvolt.co.uk/best/best-electric-mountain-bikes Publisher: Pedal and Volt. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://pedalandvolt.co.uk/how-we-pick An electric mountain bike only stays a bicycle in UK law if the motor is rated at 250 W and assistance cuts out at 15.5 mph (25 km/h). Plenty of e-MTBs on Amazon exceed that, so every bike here has a listing that states both figures and mentions no throttle or electric-only mode. For trail use, look at suspension (front only or front and rear, and how much travel), motor torque in Nm for steep climbs, battery size, tyre width, and whether the brakes are hydraulic. Weight matters too, because you will lift the bike over stiles and gates. Most budget e-MTBs do not state fork travel, so we flag that where it is missing. This guide compares five bikes on those facts as each maker lists them. ## Products ### 1. GB1 27.5" Road-Legal Electric Mountain Bike Battery: 374.4 Wh; Brakes: Shimano hydraulic disc; Gears: Shimano Altus 7-speed; Weight: 28.6 kg; Warranty: 1 year A 27.5 inch e-bike certified to EN 15194 with branded Shimano brakes and gears. The clearest choice on compliance and parts in this price band. In its favour: - The listing states EN 15194 certification, plus REACH, RoHS and UN 38.3 compliance. - Named Shimano hydraulic brakes and Altus derailleur are widely stocked parts in UK bike shops. - Five assist levels up to 25 km/h and walk assist up to 6 km/h from a 250 W hub motor. Good to know: - The 374.4 Wh battery is modest and no range figure is given. - 28.6 kg with a high tensile steel frame makes it heavy to carry. ### 2.

A big battery for the money. In its favour: - A 540 Wh battery with a claimed 90 to 120 km range, among the largest in this group. - The listing states 250 W, 50 Nm and the 15.5 mph UK legal limit. - Brake-activated rear light, 3 W front light and a USB port are included. Good to know: - Brakes are mechanical rather than hydraulic, so expect more cable adjustment. - At 29 kg it is heavy, and the listing says the rear is a hardtail despite a dual-suspension title. ### 4.
