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.

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.

The motor of the Uni4 is HONBIKE proprietary to offer our users the best riding experience. It’s a 36V 250W rear hub motor that delivers 45Nm of boost torque.

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. 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 Uni4 with luggage in a safe area before riding on public roads.

Honbike Uni4 supports a maximum range of 100 km* on a single charge.

* Test Conditions: Riding mode: Eco; Wind conditions: Light breeze; Terrain: Mostly flat; Rider’s Weight: 75kg; Temperature: 25 degrees, Tyre Pressure: Maximum.

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.

Uni4 can run at 9-12 mph (15-18 km/h) up an 18% grade hill (load: 85 - 90kg) with maximum power assistance.

Yes, Honbike Uni4 is a single-speed e-bike with a gear ratio of about 2.5. However, you can use electrical power to assist you to tackle different terrain without the need for multiple gears. Besides, Honbike Uni4 has a built-in SmartHON system that adjusts and delivers the power assistance you need based on the terrain and your riding behavior. It gives you adequate power assistance when riding on flat terrain and offers an additional power boost to make your uphill rides a breeze. You don’t have to worry about which gear to switch on when you go uphill and back to flat terrain. Let the Honbike SmartHON system do the job for you and make your riding experience as easy and comfortable as possible.

The US and EU version differs in motor power. The US version is with 350W motor power while the EU version is with 250W motor power.

Thanks to the unique design and engineering confidence, Honbike Uni4 is higly water-resistant, it allows you to clean the bike with a hose directly and you can even store or ride the bike during light showers.

• Clean and lubricate moving parts regularly.
• Check that all hardware is tightened to the torque specifications listed in the Recommended Torque Values section of this manual.
• Check your brake pads for signs of wear. Replace if necessary.
• Check the frame, front fork, kickstand, and belt for any damage, deformation, or cracks.
• Check all wiring harnesses (such as brake wires, front light wires ) of the whole bicycle for any damage or wear.
• Check the charger and its wiring harness for damage and check if the bicycle can be charged normally.

Quarterly (or every 1500kms/ 900miles)

• Check all items on the monthly service list above.

Compared with conventional ebikes, the HONBIKE Uni4 is low maintenance with fewer complicated parts that require less attention for simplicity. After riding for a period of time, like any bicycle, some parts may loosen, wear or become damaged, so inspection and maintenance at regular intervals will extend the service life of your HONBIKE Uni4 and prevent damage and potential accidents. Store your HONBIKE Uni4 in a clean, dry place to avoid rust and corrosion.

The maintenance of HONBIKE Uni4 is generally divided into the following tasks:

• Cleaning: Wipe the whole bicycle and parts with a damp rag and a low residual cleaner. Clean the belt when it’s visibly dirty. Dry thoroughly after cleaning to prevent corrosion and rust.

Remove any oil residue on the brake discs.

• Inspection: Brakes, tires, lights, and belt should be inspected regularly. Please refer to the sections “Before the First Ride” and “Before Every Ride”.
• Tightening: The fasteners of the whole bicycle should be tightened periodically by referring to the section of Recommended torque Values.
• Lubricate: Clean and lubricate the joint between the pedal and the crank.

• Adjustment: Brakes should be adjusted periodically. Ensure front anad rear brakes work properly. Check brake cable tension, replace brake cables if necessary.

• Replacement: If a part is damaged or unusable or has any cracks, scratches or color changes, the part has reached the end of its service life and should be replaced promptly.

• In order to get the maximum life from your battery you should take care to use, store and recharge it correctly.
• The battery is generally not fully charged when the bicycle is stored and transported. So be sure to fully charge the battery before using it. If the battery is used without fully charging, its service life will be compromised.
• Disconnect the battery after it is fully charged, and do not charge it for more than 5 hours each time.
• Do not leave the bicycle unattended when it is being charged.
• Never charge your bicycle in a room that does not have an appropriate smoke detector. Make sure you can hear your smoke detector throughout your house.
• When charging, please place the bicycle in a safe place inaccessible by children.
• Battery charging and discharging conditions: the battery shall be charged at 0°C~45°C and discharged at 0°C~60°C; If the bicycle is used in cold weather, leave it indoors for at least an hour to reach room temperature before charging.
• When the battery is not used for a long time, please charge it for 30 minutes or to 75% every three months, to prevent over-discharging. Over-discharging will lead to permanent damage to the battery.
• The bicycle shall be protected from impacts, rain, water immersion, heat ources, destruction of appearance and short circuit of terminals.
• Please do not disassemble the bicycle and the battery without permission. HONBIKE is not responsible for any problems caused by unauthorized disassembly.

HONBIKE Uni4 has equipped the Gates Carbon Drive™ belt that is extremely durable and offers long life when properly handled.

• Wash with water to remove debris
• Do not twist, backbend, crimp, invert, bundle, or zip tie the belt. Do not use the belt as a strap wrench or chain whip. Do not lubricate, pry on, or roll on the belt.
• Proper belt tension is essential for optimum operation of the Gates Carbon Drive System. Lack of belt tension can lead to “skipping”. Too much tension can damage other components and increase the wear of your Carbon Drive System. The Gates Carbon Drive Mobile App can measure the belt tension in the form of the natural frequency (Hz) of the belt span.
• Replace your belt when it shows these signs of wear and tear.

The frame number of HONBIKE Uni4 can be found on the frame. It consists of 15 digits. You can also find it on the back of your owner's manual.
