Maximum Permitted Overall Weight; How To Increase Riding Mileage; Before The First Ride - HONBIKE U4 Benutzerhandbuch

Maximum permitted overall weight

HONBIKE U4 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.
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.
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. Sudden shifts in load while riding
can affect your balance and lead to serious injury or death. We recommend that you practice
how to control the HONBIKE U4 with luggage in a safe area before riding on public roads.

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 U4 range.
To maximize the range of HONBIKE U4, 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
• 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.

Before the first ride

Before riding the bicycle, please read the manual carefully to make sure you understand each
section of the manual. Familiarize yourself with the bicycle and its controls before riding in traffic.
1. Check if the front fender bolts, front wheel nuts, brake lever bolts, saddle
adjustment bolt, and saddle clamp bolt are tightened before riding.
2. Electrical system
• Make sure that you are familiar with the functions of all buttons and the
meanings of the display information by referring to the content in the relevant
sections of the electrical system.
• Before you set off for the first time, check whether the battery is fully charged.
• Check if the front light and rear light can be turned on normally and if the front
and back reflectors are not damaged.
• Check if the display works normally.
3. Transmission system
• Push the bicycle forward and backward, check whether the front and rear
wheels can rotate smoothly to ensure that there is no stalling or unsteadiness
during riding.
• To inspect the belt, rotate the rear wheel and check the inside and outside
4. Tires
• Check tire pressure. Press the tires with your thumbs, which shall be solid and
firm. If the tire pressure is insufficient, inflate to an air pressure of at least 3.4 - 3.6
bar (50 Psi), but over-inflation(4.2 bar) should be avoided.
5. Handlebar
• Check whether the handlebar and front wheel are straight. Make sure the groove
6. Saddle
• Adjust the saddle to a proper height. Check that you can reach the floor with the
tip of your toes when sitting on the saddle.
• Check if the seat post is locked tightly before riding to ensure that the saddle
and seat tube are securely fastened.
7. Brake
• During the assembly at HONBIKE, the right brake lever is used to control the rear
brake and the left brake lever is used to control the front brake. Check if the brake
setting could match with your habit. Try to use the rear brake first when braking.
In the UK, China and Japan, the brake setting is different with the left brake lever for rear brake
and the right brake lever for front brake.
