Speed
The Q1 model has a absolute top speed of 10 mph, however the normal driving speed is 8 mph. When the speed goes above 8 it will lean slightly backwards to make you slow down, and a warning beep is heard. 8 mph is a very comfortable and safe speed.
Climbing
The Q1 can drive up hills of 15°. People of max 130lbs can climb 18°. (15° is quite steep!)
Battery
Airwheel Q1 has a great performing 260 WH battery from Japan with UN38.3 certificate capable of 1800 recharge cycles
Range
The range of the Q1 is up to about 18 miles. This will vary based on your weight, speed, terrain, temperature and how you drive it. The most efficient way is to drive at a constant medium speed. Frequent stops and accelerations will use more battery. In real life usage tests you can expect 8-10 miles for a 150lbs person.
