An e-bike with front and rear suspension, Shimano shifting, and a battery hidden in the frame—less than €500 isn’t something you see every day. Aairsk GT900 is the younger and cheaper sibling of Aairsk XT90: it has a smaller battery, but the equipment is noticeably similar. It’s mainly for those who want one bike for commuting to work and for weekend rides on forest roads, without paying thousands of euros for it.
You probably won’t even believe the price of €450
You can find the Aairsk GT900 e-bike at the trusted seller MAIRIDE E-Bike Store, which has 94% positive ratings on AliExpress. It’s located directly in a German warehouse, meaning delivery in roughly a week and with no additional charges—VAT is already included in the price, and customs duty doesn’t apply. Shipping is free. Don’t forget to use the coupon from the price box as well—it will take another €60 off the price.

A 45 N·m motor and the legal limit of 25 km/h
In the rear hub there’s a brushless motor with a rated output of 250 W, i.e., exactly as much as an e-bike with pedal assist is allowed to have in Europe. The torque of 45 N·m isn’t record-breaking, but for city traffic and gentle hills it’s more than enough. The manufacturer claims it can handle climbs up to 20 degrees and a maximum assisted speed of 25 km/h.
The 21-speed Shimano drivetrain handles the shifting, so on steeper sections you can rely on the easier gears and on flat roads you don’t need to pedal unnecessarily fast. Just keep in mind when choosing that it’s a hub motor—not a mid-drive motor with a torque sensor like on pricier mountain e-bikes. That’s why the motor support kicks in less smoothly, and the GT900 isn’t meant for demanding off-road terrain.
Removable 468 Wh battery in the frame
The 36 V battery with 13 Ah capacity—that is, 468 Wh—is integrated into the slanted frame tube. It’s removable and swappable, but watch out for one detail: according to the seller’s graphics, you can’t charge the battery while it’s removed from the bike. If you park the bike in a basement without an outlet, don’t count on charging it in your apartment. The battery is protected by a BMS system.
Take range figures with a grain of salt. On the manufacturer’s own graphics they state a real 30–40 km, while the offer parameters list a range from 31 to 60 km. The upper limit applies to the lowest assist level, on flat terrain, and with a lighter rider. If you want more, the sister XT90 has a battery with almost 960 Wh capacity—but it also costs more.
NFC card unlocking and an LCD display
A highlight in this price range is unlocking without a key. Just hold an NFC card to the display and the bike turns on—then with the same motion you lock it again. There’s an LCD display on the handlebars showing speed, assist level, and battery status, plus a front light with a horn.
In the seller’s images, there’s also a thumb-controlled throttle on the handlebar. Keep in mind that a bike with a throttle that lets it go faster than 6 km/h without pedaling no longer meets the EU definition of a normal pedal-assist bicycle. Before your first ride, check how it’s set up, or ask the seller for details.
Front and rear suspension and 26″ Kenda tires
The Aairsk GT900 features a front suspension fork with hydraulic lockout and a rear spring shock. On asphalt, you can lock the fork so it doesn’t bounce unnecessarily; on dirt or forest paths, you unlock it so it can smooth out bumps. The bike comes with 26-inch Kenda tires with a more aggressive tread, and it’s stopped by mechanical disc brakes both front and rear.
The bike weighs 26 kg, which is a typical figure for an e-bike with suspension, but you’ll be carrying it up and down stairs reluctantly. Payload is 150 kg, and the manufacturer recommends riders with heights from 156 to 185 cm. The offer rating is currently 4.4 out of 5, but it’s based on just seven reviews, so it’s still too early for clear conclusions.
