Throttle and public-road use in Great Britain
A 250W label or 25km/h setting alone does not establish EAPC compliance. The complete cycle must have usable pedals, no more than 250W maximum continuous rated motor power, an assistance cut-off at 15.5mph, and the required markings and safety equipment. Walk assist limited to 3.7mph (about 6km/h) is outside the throttle type-approval requirement. A twist-and-go cycle introduced after 1 January 2016 that can propel itself without pedalling beyond walk-assist speed requires type approval or individual approval, even if it meets the EAPC power and speed limits. An approved twist-and-go EAPC can still be treated as a pedal cycle; a throttle does not automatically make every bike unlawful.
Using pedal assist, avoiding the throttle or choosing a lower display setting does not establish compliance. Department for Transport guidance also treats cycles with a selectable mode capable of motor propulsion above 15.5mph as motor vehicles. Where the supplied configuration or required approval has not been verified, do not use the bike on public roads or cycle paths as an ordinary EAPC. Use only on suitable private land with permission unless the applicable road-use requirements are met. Read the official EAPC and throttle guidance.
The Aairsk GT300 and Aairsk GT900 are both 26-inch electric bikes built for UK commuting and leisure riding, and both are available now from E Bike Market. They share the same 250W motor rating and a similar frame size, which makes it easy to assume they are interchangeable. Once you compare the battery capacity, gearing and suspension, the two bikes are set up for slightly different journeys. This guide compares them feature by feature to help you choose the right one.

Which offers better value for you?
Both bikes share the same 250W motor rating and 25km/h assisted speed limit, so neither has a higher listed assistance limit; road-use classification requires further checks. The difference is in how each one handles the ride.
The GT300 is the simpler, lighter option. With 7-speed gearing and front suspension, it suits mostly flat, paved commuting routes where you want dependable electric assistance without paying for capability you won't use. At £429.99, it's the better-value choice if your riding is mainly road and cycle-path based.
The GT900 costs £60 more but adds a 30% larger battery, dual suspension and 21-speed gearing. That combination is worth the extra cost if your route includes hills, uneven surfaces or longer distances, since the wider gear range makes climbing easier and the rear suspension adds comfort that the GT300 doesn't have.
In short: choose the GT300 for straightforward, lower-cost commuting, and the GT900 if you want more range and a smoother ride over varied terrain.
UK legal information
Both listings state 250W and a 25km/h assistance cut-off, but both also describe throttles. These figures do not establish road-use EAPC status. Obtain confirmation of actual throttle operation and any required approval for the supplied unit before public-road use.
