Why consider the Aairsk S800?
The S800 sits in Aairsk's everyday 26-inch e-bike range. Its removable battery is particularly useful for riders who want to charge away from the bike, while the Shimano 7-speed drivetrain and front suspension give it a familiar bicycle-style specification for commuting and leisure use.
250W motor for everyday riding
The S800 is listed with a 250W motor and a maximum assisted speed of 25km/h. Buyers should still check the bike's exact configuration and throttle operation before public-road use in Great Britain.
Removable 36V 10Ah battery
A removable battery can make charging more convenient, particularly where the bike is stored in a garage, communal area or somewhere without an accessible socket. The S800 uses a 36V 10Ah removable battery.
Range
The supplier estimates approximately 30-35km in throttle mode and 35-55km with pedal assist. These are estimates rather than guaranteed distances. Rider weight, gradients, temperature, wind, tyre pressure and assistance level can materially affect real-world range.
26-inch wheels, Shimano gearing and front suspension
The 26-inch format makes the S800 a conventional full-size everyday e-bike. Shimano 7-speed gearing gives riders a choice of mechanical gears, while the front suspension is intended to improve comfort over uneven surfaces.

S800 vs S600
The closest comparison is the Aairsk S600. Both use a 250W motor, 26-inch wheels, Shimano 7-speed gearing, front suspension and a removable battery. The main listed difference is battery capacity: the S600 has a 36V 13Ah battery versus 36V 10Ah on the S800, and its supplier-estimated pedal-assist range is correspondingly higher.
S800 vs GT300 and Q7
The GT300 and Q7 share several core specifications with the S800: 250W motor, 36V 10Ah battery, 26-inch wheels, Shimano 7-speed gearing and front suspension. The S800's key product-page distinction is its specifically listed removable battery.
S800 vs GT900
The GT900 moves towards a mountain-bike specification with a 36V 13Ah battery, Shimano 21-speed gearing and dual suspension. Buyers prioritising battery capacity, more gears and additional suspension may prefer the GT900; buyers wanting a simpler removable-battery everyday bike may prefer the S800.
S800 vs X5 and XT90
The X5 and XT90 are materially different. They use higher-capacity 48V batteries and supplier-listed selectable 250W/500W configurations. Their 500W or unlocked configurations are not EAPCs for UK public-road use and are intended for appropriate private-land use. The S800 is the more conventional option for shoppers specifically searching for a 250W everyday e-bike.
Is the Aairsk S800 road legal in the UK?
Great Britain has specific rules for electrically assisted pedal cycles (EAPCs). The S800 is listed with a 250W motor and 25km/h maximum assisted speed, but public-road legality can also depend on the exact configuration and how the throttle operates. Buyers should check the current GOV.UK electric bike rules and confirm the configuration before riding on public roads.
