4.General Questions of Uni4
Charging the battery
When the battery is running out, the last grid of the battery indicator would flash, which means the battery needs to be charged immediately. Gently open the rubber cover and insert the charger plug into the charging port. It takes about four hours to complete charging, and when the color of the charger light turns from red to green, the battery is fully charged. Unplug your charger and put the rubber cover back on when your bike is fully charged.
Can I also use Honbike Uni4 when the battery is empty?
Yes, without the battery, you can still pedal your Honbike Uni4 as a regular bicycle with the added benefit of low maintenance and arriving with clean trousers.

Maximum permitted overall weight
HONBIKE Uni4 can carry a maximum load of 120kg. Riding range and speed will be affected by the load carried by it, power assist settings, road conditions, tyre pressure and weather conditions.
NOTE: Exceeding the loading capacity will void all warranties and may result in unsafe operation of the product, which in turn may affect your life safety.
NOTE: Make sure you have good control of the e-bike carrying your luggage and keep it balanced. If you can't control it well, please reduce the weight of the luggage.

How to increase riding mileage?
Many conditions may affect the range of the bicycle, including load, riding speed, rider's pedal power, tire pressure and type, road conditions and weather conditions. Continuous use of motor assist and/or selecting the highest speed mode while riding will reduce the HONBIKE range.
To maximize the range of HONBIKE, you can try the following method:
- Try to pedal as much as possible.
- We recommend you to use the low power assist level to ride the bicycle on flat roads or downhill roads and select the high power assist level when riding against the wind, uphill, and with heavy loads.
- Try to keep the load to a minimum level.
- Inflate the tires properly and keep the tire pressure within the normal range.
- In case of poor road conditions (e.g., bad pavement, potholes or speed bumps), reduce the speed and adjust the riding modes.
How to set the pedal assist level?
Uni4 is equipped with four riding modes.
Bicycle mode: The motor will not offer any assistance, but the display and lights will still function.
