FAQs
What is the maximum range of the Aairsk Q7?
The bike offers a range of up to 64 km depending on rider weight, terrain, and assist level.
Can I ride this bike in the rain?
While the components are water-resistant, it is not waterproof; avoid deep puddles and do not pressure wash the electrical components.
How long does it take to fully charge the battery?
Charging times typically range from 6 to 8 hours depending on the remaining charge level.
Is the bike suitable for off-road trails?
It is designed primarily for city and leisure riding; it can handle light gravel and dirt paths but is not intended for technical mountain biking.
What tire pressure should I use?
Refer to the sidewall of your specific tire, as pressures vary based on terrain, but typically fall between 20-30 PSI for these fat tires.
Troubleshooting
Bike does not power on
Ensure the battery is firmly locked into the cradle and that the battery power switch is toggled to the ON position.
Poor acceleration or hill climbing
Check tire pressure to ensure it meets the recommended PSI; low pressure increases rolling resistance.
Gears skipping during shifts
Adjust the rear derailleur barrel adjuster or visit a local bike shop to align the derailleur hanger.

Setup, Compatibility & Care
Upon receiving the Aairsk Q7, ensure all bolts—especially those connecting the handlebars and pedals—are tightened to the manufacturer's specifications. Before the first ride, fully charge the 48V battery using the provided charger to calibrate the battery management system. For routine maintenance, check the tire pressure weekly, as the fat tires are sensitive to under-inflation which can drastically reduce range. Keep the chain clean and lubricated every 150-200 km to ensure smooth gear shifting. When storing the bike, keep the battery between 40% and 80% charge if it will be unused for more than a week to extend its overall lifespan. Avoid exposing the electrical components to heavy rain or high-pressure water sprays during cleaning.
