Why I have insufficient travel distance and poor endurance with my bike?

1. The travel distance and the endurance is closely related to load, road condition, frequent braking and acceleration and deceleration. Load 60kg, at a flat road, the current speed is about 1~2A at a uniform speed, but the current of acceleration and upslope will reach 12A when the load is 75kg, the constant speed of current on the flat road is about 4~6A, the unit capacity of the battery is mAh, indicating the integral of the current in time, and can also be simply understood as the product of the discharge current and the discharge time.

In conclusion, the different mileage will be different when in different load, road condition, the frequency of acceleration or deceleration and so on.

 

2. Possibly a part of the users see the electricity indicator shows last grid or yellow light, then they think the battery runs out. It is inaccurate to calculate the range of the endurance in this way. The last grid or the yellow light means low battery. According to the different circumstances, the following mileage can continue to be different.

After the test, when the load is 60kg,  battery at the last grid or the bright yellow light is on, and the bike is still, the deluxe version can continue to run 15km, and the standard version can continue to drive 5km. Even a few users saw only one blue light on the meter, and they thought it was no power, doubting that the battery was insufficient or the range was insufficient, it’s not scientific.

The endurance of the bike is strictly tested by the factory. Carrying 60kg, running on a flat road, from full power to full ride, and the milage is the same as DYU official states.

 

3. Full electricity charge condition needs to relate with the charger light, when the bike power dashboard turns bright blue, it only indicates the quantity of electricity is more than 80%.  When the charge turns from red to yellow-green, it is full then.


DYU Bike D1 or DYU Bike D2, which is better?

D1 has no pedal while D2 has. D2 is better for the long trip while D1 has shorter mileage. The best one is the most suitable one for your specific use. Both are good and comfortable for riding.
