Start with how and where you plan to ride. Step-through models are designed for easier everyday access and comfortable riding, folding models focus on compact storage and transport, while electric mountain bike models offer suspension and gearing suited to more varied terrain.

Compare the wheel size, frame style, battery design, suspension, gearing and estimated range shown on each product page before choosing.

Wheel size affects fit, handling and overall ride feel. Smaller wheels can make a bike feel more compact and easier to manage, while larger wheels can provide a more familiar full-size riding experience.

Check the size information on the individual product page, as the best fit can also depend on rider height, proportions and personal preference.

Range varies by model, battery configuration and riding conditions. Where an estimated range is shown on a product page, it should be used as a reference rather than a guaranteed riding distance.

Rider weight, terrain, speed, temperature, tyre pressure, riding mode, hills and stop-start riding can all affect real-world range.

Battery design varies by model. Some AAIRSK e-bikes use removable batteries for convenient charging, while others use an integrated battery design.

Please check the battery information on the specific product page before ordering.

E-bike regulations vary by country and region, and requirements can differ depending on motor rating, assisted speed, throttle configuration and where the bike is used.

Please review the specifications of the model you are considering and check the applicable local rules before riding on public roads.

No full bike build is normally required. AAIRSK e-bikes arrive mostly pre-assembled, with only a few final components requiring installation before your first ride.

Follow the supplied instructions carefully and complete all recommended safety checks before riding.

Standard AAIRSK e-bike packages include the electric bike, compatible charger, pedals, bike lock, user manual, installation tool, bike pump and card keys where applicable.

Package contents can vary by model or production version, so please refer to the product page for the most relevant information.

We recommend checking the battery level and following the charging instructions supplied with your e-bike before the first ride. Always use the compatible charger supplied for your AAIRSK e-bike.

Orders are fulfilled from the nearest available regional warehouse where possible. If the nearest warehouse does not have the selected model in stock, the order may be fulfilled from another available warehouse.

AAIRSK normally processes orders within 1–2 business days. After dispatch, carrier transit is typically around 3–10 business days, depending on the destination and carrier.

A typical order may therefore arrive in approximately 4–12 business days. AAIRSK internal processing days are based on Hong Kong Time (HKT, UTC+8), Monday to Friday excluding Hong Kong public holidays. Carrier schedules may follow local operating days.
