Looking for an electric mountain bike without spending £700+? We've compared three Aairsk models in UK stock to help you find the right balance of price, range and capability for 2026.
Aairsk GT900 – Best Value Full-Suspension Pick (£489.99)
The Aairsk GT900 is our top pick for anyone wanting genuine dual suspension without a premium price tag. It pairs a 250W motor with a 36V 13Ah battery, 26-inch wheels and Shimano 21-speed gearing, giving an estimated 30-40km range in throttle mode or 40-60km with pedal assist. Front and rear suspension take the edge off potholes and uneven trails, and the 21-speed drivetrain keeps pedalling efficient on hills.
Aairsk GT300 – Lighter Everyday Alternative (£429.99)
The Aairsk GT300 is the more affordable, city-focused sibling to the GT900. It's built for commuting and leisure riding rather than off-road trails, with a smaller 36V 10Ah battery. If your riding is mostly pavement and towpath rather than bridleway, it's worth comparing against the GT900 before you buy — see our full GT300 vs GT900 comparison for a detailed side-by-side.
Aairsk XT90 – Step Up for Longer Rides (£609.99)
If you want more range and a bigger battery, the Aairsk XT90 moves up to a 48V 20Ah battery for an estimated 45-100km range depending on mode, alongside the same dual suspension and 21-speed Shimano setup as the GT900. Note that the XT90's higher-power configuration is supplied for private-land use rather than public roads — check the product page for the current specification before ordering.
UK E-Bike Law At A Glance
Whichever model you're considering, it's worth checking the current rules before you ride on public roads. Under UK EAPC (Electrically Assisted Pedal Cycle) regulations, a road-legal e-bike needs a continuous motor power no higher than 250W, must stop assisting at 15.5mph (25km/h), and must be pedalled rather than throttle-only to qualify. Full detail is on GOV.UK's electric bike rules page. Configuration can vary between units and suppliers, so always check the specific bike you're buying rather than relying on the model name alone.
