1. Which GT300 size should I choose?

The GT300 is available in 24″ and 26″ versions.
As a general guide, the 24″ model is suitable for riders around 155–170 cm, while the 26″ model is better suited to riders around 165–185 cm.
If you fall between the two sizes, choose 24″ for a more compact feel or 26″ if you prefer a larger-wheel, full-size riding experience.

2. How far can the GT300 travel on one charge?

The GT300 offers an estimated riding range of up to 40 km.
Actual range varies with rider weight, terrain, riding mode, assistance level, speed, temperature and riding conditions.
Using pedal assist and moderate assistance levels can help make more efficient use of the available battery capacity.

3. What happens when the built-in battery needs replacing?

The GT300 uses a built-in lithium-ion battery rather than a routinely removable battery.
If battery replacement is needed, contact AAIRSK Support for compatible battery information and replacement guidance.
Replacement battery and parts support helps keep the bike serviceable beyond the original battery life.

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

The GT300 is covered by an AAIRSK 2-Year Warranty.
AAIRSK also provides support for compatible replacement batteries, essential parts and product-related after-sales questions.
If you need assistance, contact our support team with your bike model and order information so we can help identify the correct solution.

Great bike I did some upgrades on mine more lights put Kevlar tires on it fatter seat cuz I'm a big boy more lights and if they made a 4-in fat tire version with double hub of this model I would buy it I ride it daily and enjoy it every time I do

I really like this bike I wish they made one with a double hub just like it with the 4-in tires I'd buy one of them too I've made this custom for me did a few upgrades got a fat seat some mirrors added more lights the essential upgrades tires wouldn't that great but I got some cavalar lawn tires from Amazon which was an easy upgrade I enjoy it I ride it daily

A Blast on Any Terrain!

This e-bike is an absolute game-changer for my weekend adventures. I've taken it on paved trails, gravel paths, and even some light mountain biking, and it handles everything beautifully. The front suspension is a lifesaver on bumpy terrain, and the all-terrain tires provide great grip. The three riding modes are perfect—I use pedal assist on long stretches and switch to full motor mode when I need a break. The card key unlock is a cool, modern feature, and the bright headlight has been essential for those late-evening returns. So much fun!"

A Perfect Introduction to E-Biking

This is my first e-bike, and the entire experience has been fantastic. The setup was straightforward, thanks to the 90% pre-assembly. The online video guide was clear, and I had it ready to ride in no time. The instructions clearly explained the Class 2 specifications (throttle and 22 mph limit), which made me feel confident it was legal and safe for my local trails. The three modes (pure electric, pedal assist, and regular bike) let me learn and get comfortable at my own pace. Now, I'm using it for my commute and having a blast. If you're on the fence about your first e-bike, this is a terrific choice

Perfect for My Hilly Commute!

"I was skeptical about an e-bike's ability to handle the hills in my city, but the GT300 makes it feel effortless. The 400W motor is surprisingly powerful and easily gets me up steep inclines without breaking a sweat. The 7-speed Shimano gears are smooth, and I love having the option to use the throttle from a complete stop. The 40-mile range is more than enough for my daily round trip, and the detachable battery makes charging at my desk super convenient. It feels sturdy, safe with the disc brakes, and arrived almost fully assembled. A fantastic value for the price!"
