Remarks: power, load, tire pressure, road environment, chain and axle lubrication
will affect the maximum speed; The endurance mileage is obtained from the
continuous test with load of 60kg, speed of 15 ~ 25km / h, flat and hardened road
surface, from full charge to complete power consumption; Driving habits,
temperature, load, tire pressure, road environment and other factors will affect the

III Key introduction:
The specific combination positions of keys are as follows:
Introduction to key use
The key operation is divided into short press, long press and long press with
combination keys.
Short press is used for fast / frequent operations, such as:
1. When riding, you need to modify the boost / speed
gear, briefly press it;
2. When riding, switch the multi-function area to display data, and
briefly click

Single key long press is mainly used for mode / switch state switching. The
composite key (long press) is used for parameter setting. Because the operation
is complex, it can reduce misoperation (short press does not make composite key,
because it is easy to trigger by mistake, and the operation is too difficult).
Specific operation explanation
1. Modify the boost ratio / electric gear, assuming that the current mode is boost
mode
Short press , boost + 1;
Short press , boost - 1;
2. Switching speed:
