Quiet motor for relaxed riding
Glide through city streets with barely a whisper, thanks to the brushless hub motor. It delivers smooth, consistent power without the drone of older designs, so you can enjoy the sounds of the city around you. Perfect for early morning commutes or leisurely weekend rides.
Your everyday city companion
The Aairsk 24" Cruiser CITY is built for the joy of cycling, with pedal assist that makes every journey feel effortless. Feel the wind in your hair as you chase the horizon, whether you're nipping to the shops or exploring new routes. It's about freedom, fresh air, and the simple pleasure of two wheels.
This bike meets UK road regulations, offering three riding modes to suit your mood: pure electric, pedal assist, or a sporty boost when you need it. Ride legally and confidently on UK streets, knowing you're within the 250W limit and 15.5 mph assisted speed.
Ready for the British commute
With a 36V 13Ah lithium battery, you can cover up to 37 miles on a single charge in electric assist mode, making it ideal for daily trips across town. The 24-inch wheels and lightweight aluminium frame keep the ride nimble, while the front suspension fork smooths out potholes and cobbles. Weighing in at 55 lbs, it's manageable to store at home or in the office.
Shimano 7-speed gears and mechanical disc brakes give you control in all weather, and the bright LED front light keeps you visible on dark UK evenings. The LCD display puts key info at your fingertips, and the package includes everything you need: charger, pump, tool kit, pedals, and a lock.
Power that adapts to you
The 250W hub motor offers three distinct modes to match your ride. Choose pure electric for effortless cruising, pedal assist for a natural cycling feel with a helpful boost, or ride unassisted when you want a workout. It's all about flexibility on UK roads, where the motor cuts out at 15.5 mph to keep you legal.
With 45 Nm of torque, it handles gentle hills and headwinds without breaking a sweat. The 7-speed Shimano drivetrain lets you find the perfect cadence, whether you're accelerating from traffic lights or maintaining a steady pace along a canal towpath.
Ride further with a removable 36V battery
Enjoy the freedom to go the distance with a high-capacity 36V 13AH lithium-ion battery, delivering up to 37 miles of pedal-assisted range on a single charge. When you need a boost, the pure electric mode still gives you a handy 19 to 25 miles, perfect for nipping through town. The battery is easily removable, so you can charge it at home, in the office, or anywhere with a standard socket – no need to park your bike near a plug.
Smooth out bumpy British roads with front suspension
Potholes and uneven tarmac are no match for the front suspension fork, which soaks up shocks to keep your ride comfortable and controlled. You’ll notice less fatigue in your hands and arms, even on longer journeys, while the bike feels more stable and predictable. By cushioning the frame and components from jarring impacts, the suspension also helps protect your e-bike over time.
Stay in command with the smart LCD display
Glance at the clear LCD screen to check your speed, battery level, and assist mode, so you’re always in the know. Choose from five levels of pedal assist to match your mood and the road ahead – from a gentle nudge up to the full 15.5 mph allowed under UK regulations. For extra security, simply tap the included NFC card on the display to unlock your bike, and tap again to lock it when you park up.
When you want effortless cruising, the twist throttle lets you glide along without pedalling, ideal for pulling away from traffic lights or tackling a steep hill. The five assist modes give you precise control: from a leisurely 7.5 mph in PAS 1 up to the maximum assisted speed, so you can tailor the ride to your fitness and the conditions.
Stop confidently with dual disc brakes
Whether you’re caught in a sudden downpour or navigating a busy high street, the dual disc brakes deliver reliable stopping power when you need it most. They offer consistent, controlled braking with less effort at the lever, and the design sheds heat quickly to maintain performance on long descents. It’s a reassuring safety net that keeps you in charge, whatever the British weather throws at you.
Ride with less maintenance
Enjoy a smoother journey thanks to the water-resistant chain, which keeps grit and moisture at bay. This design helps you spend more time riding and less on upkeep, even after splashing through typical British rain.
See and be seen clearly
A bright front light cuts through gloomy mornings and dark evenings, making your path ahead sharper and more visible. The rear reflector boosts your presence on busy UK roads, helping other road users spot you sooner.
Stay comfortable on every trip
The saddle is designed for all-day ease, with height adjustment to suit riders of different statures. Whether you're nipping to the shops or commuting across town, you'll arrive feeling fresh.
Choose how you ride
With seven speed modes, you can fine-tune your effort and assistance to match the road ahead. Switch between pure electric for up to 25 miles, pedal-assist for around 37 miles, or use the manual pedal mode for a traditional cycling workout.
Built to fit most riders
The 24-inch wheels suit a wide range of heights, from about 5 feet to 6 feet 3 inches. The bike itself weighs 58.6 lbs and can carry up to 330 lbs, making it a sturdy choice for everyday errands or leisure rides.
