1. How far can the GT900 travel?

The GT900 offers up to 52 km of estimated riding range under suitable riding conditions. Actual range may vary with rider weight, terrain, gradients, temperature, riding mode, speed, tyre pressure and other conditions.

2. Should I choose the 24″ or 26″ GT900?

The 24″ GT900 offers a more compact and easier-to-manage riding setup, while the 26″ version provides a more full-size riding feel. As a general reference, the 24″ version is suitable for riders around 155–170 cm, while the 26″ version is suitable for riders around 165–190 cm. Individual fit may vary depending on body proportions and riding preference.

3. Do I need a licence or registration to ride the GT900 in Europe?

The EU/UK road-compliant GT900 is a pedal-equipped electric bicycle with fully functional pedals, a 250W continuous-rated motor and electric assistance limited to 25 km/h (15.5 mph). In Great Britain, a compliant EAPC does not require a driving licence, vehicle registration, road tax or motor insurance. In EU countries, standard compliant 250W / 25 km/h pedal-assist e-bikes are generally treated as bicycles, although local classification, age, helmet, insurance and road-use rules may vary by country.

4. What warranty and after-sales support do I get?

The GT900 includes a 2-year warranty for the frame and 1-year coverage for the battery, motor, controller and other eligible original components. AAIRSK also provides after-sales support, with compatible replacement batteries and essential parts available for supported models.

Bought one of these at the beginning of February 2026 and I've been satisfied with its performance so far.(as of the end of march 2026) It's managed to handle riding through Canadian ice and snow just fine for almost two months as I ride year round, the specs are all as advertised,(and quite good for the price) it's fairly light for an ebike, pretty nimble, and not that much bigger than a normal trail bike would be. Though keep in mind, this isn't a high end bike you'd throw down a technical trail as hard as you can, this is much more suitable for casual riding on light trails.

My only complaints are: I haven't found a way to change the computer from Mph to Kph(no big deal,) the brakes were wired up backwards from the factory(I can fix that any time now that the weather is warm,) and the bracket on the front brake that helped hold the pads in place snapped under moderate pressure, that's probably something both the manufacturer and potential buyers should keep an eye on.

Otherwise, it's been a great bike for the price and I would recommend buying it if you want an Ebike that's suitable for street use and light off-road riding.

I purchased this ebike during Black Friday sales from Walmart Canada marketplace seller. I checked everything (tires, electronics, motor, brakes, and derailleur), all good but no ride test due to winter season. Both tires are true enough. No instructions for assembly and change the LCD display to metric unit; how to information is available online. The nice features are NFC tag to power ON/OFF the e-drive system, 21-speed derailleur, rear shock, bright headlight, loud e-horn, quick connect for front wheel and seat position, front and rear fenders, handheld air pump, cable with lock. Speed is controlled by thumb lever rather than twist handle. Despite the inconsistent motor wattage on the description, the maximum wattage is the fully charged battery wattage which is 468W (36V * 13Ah). It is a good looking bike. I wear 29" inseam pant, I can flat feet on the ground while seated.
The following items could improve. The charger is very light and has a fan that is always ON during charging. The charge port access cover is flimsy. The rear shock is plastic; I assume underneath is metal? Wires from all the devices mounted on the handlebar are wrapped in nylon mesh and tie wrapped along the frame rather than hidden inside the frame. No reflectors for front and back, and the 2 wheels. However, both pedals have reflectors and included 2 stick-on rectangular reflectors with curved backing; I could not find any place on the frame that matches the same curvature of the stick-on reflector.
Since I have not ridden it due to weather, cannot comment on the range and speed specs. Assembly was easy even without instruction. A lot of features, great bang of the buck.

Very nice bike! Easy assembly and formatted the P-settings from two short vids. Bike exactly as described! Easy to adjust disk brakes and derailleur. Did a little re-routing on some of the cables and it looks great. Shipping was fast and Bike arrived perfectly safe and sound. Came with a tool kit and a bike pump and a lock. Surprised me. Pretty quick for such a cheap price. Not sure on the mileage claims but so far everything was accurately described. My 5'8 son fits it perfectly and it fits me at 5'11 perfectly fine as well. The Shimano shifter is an older model, but shifting is very smooth. This isn't a $4000 carbon fiber bike-snob bike, but as far as 'starter' bikes go with a 2 inch wide tire and a soft tail? Best bang for the buck out there! Researched a ton of e-bikes before getting this one. A great city/soft trail bike. Would highly recommend. Bought it directly through the manufacturer and am very pleased so far. I DID upgrade the pedals as the ones that came with the bike were a little stiff. Thanks Aairsk!

Aairsk Electric Bike

couldn’t be happier with my purchase of the Aairsk Electric Bike! Right out of the box, this bike impressed me with its sturdy build and sleek design. The peak motor provides plenty of power for both city commuting and off-road trails, and I love how effortlessly it climbs hills. With a top speed of 25MPH and a range of up to 40 miles, it’s ideal for daily use without worrying about frequent recharging.
The tires and shock absorber make the ride incredibly smooth—even on bumpy terrain—and the 7-speed gear system offers great flexibility whether I’m cruising on flat roads or tackling steeper paths.
Overall, this e-bike is an excellent combination of performance, comfort, and value. Whether you’re a commuter or a weekend explorer, the Aairsk is a fantastic choice!

My Car is Now Collecting Dust!

This e-bike has completely changed my daily routine. My 12-mile commute to work is now the best part of my day. The 750W peak motor provides unbelievable power to easily handle the hills on my route without breaking a sweat. I can comfortably cruise at 25 mph on bike paths, cutting my travel time significantly. The 45-mile range is accurate; I can do two full round trips on a single charge. The build quality is solid, and the hydraulic disc brakes are super responsive. If you're thinking about replacing your car for short trips, this is the bike to do it.
