Use tips
This electric bicycle is designed to transport a single person in each use. Condition your bicycle if you want to transport luggage and try not to exceed the maximum load for which it was designed (125 kg). Failure to follow the safety advice, or activities that go beyond its intended use, such as going down steps, performing stunts or making improper repairs, will exempt both the manufacturer and the dealer from all liability. It is recommended to always wear a helmet. In case of driving at night, make sure to turn on the lights, and if possible, also wear a reflective band or vest. Remember to clean your bike regularly. To do this, avoid the use of pressurized water, since the electronic components can get wet, which can cause a malfunction and even personal injury. Carefully clean painted surfaces, plastic parts and electronic components. Never use abrasive products such as seawater, saltpeter, soda, etc.

Before each use
Before each ride, you should check that the brakes are secure and working properly. The handlebar and seat post must be in the correct position and firmly fixed. The wheels must have enough pressure and all the nuts and bolts must be well tightened. The battery must have sufficient charge for the use that we are going to give it.

Regular checkups (every 1-2 months)
These controls guarantee the perfect condition of the e-bike and optimal operation.

1. Check that the welds on the frame and fork are in good condition and show no signs of corrosion.
2.  Check that the front and rear brakes are attached to the chassis and brake effectively.
3.  Check tire pressure and tread depth.
4. Check that the rims are well secured and do not have any loose or broken spokes.
5. Check that the handlebar and the seat post are well inserted and firmly tightened.
6.  Check that the cables are sufficiently greased and that they have no obstacles in their path.
7. Check that the battery is charged enough.

Battery charge When you finish the trip or the battery is running low, charge it immediately. Charging methods can be divided into two types: one is to take out the battery and then charge it, the other is to charge the battery directly on the electric bicycle. Connect the charger plug to the battery charging port and to the power. Connect it to a 220V / 50-60Hz power supply. There is an LED indicator on the power supply. The LED is red when the battery is charging. The LED turns green when the battery is fully charged. Recommended charging time: 4-6 hours.
After charging, please unplug the input plug (from the wall outlet) first, and then unplug the output plug (from the bike). The battery charger must have constant voltage. Fluctuating voltage or fluctuating power supply of any kind can damage the storage cells of the battery.

• Checking the battery before using it for the first time

WARNING

•  The battery is supplied partially charged. To ensure the full capacity of the battery, please fully charge it before using it for the first time.

Battery care

• Even with proper care, rechargeable batteries don’t last forever. Each time the battery is discharged and subsequently recharged, its relative capacity decreases by a few percent. You can maximize the life of your battery by following the instructions in this guide. The battery should be fully charged immediately upon receipt for the full recommended charging time
•  For a full 100% charge, leave the battery on the charger for a full hour after the indicator light on the charger turns green.
•  Lithium-ion batteries have no “memory”. Partial charge/discharge cycles will not harm the batteries capacity or performance.
• The nominal output capacity of a battery is measured at 25ºC. Any variation in this temperature will alter the performance of the battery and shorten its expected life. High temperatures especially reduce the overall battery life and operating time.
•  Always make sure to turn the bike’s ignition switch to “OFF” after each use. If you leave the power switch in the “ON” position, or your electric bike has not been charged for an extended period of time, the battery may reach a point where it will no longer hold a charge.

Recycling Notice
Electrical and electronic equipment and batteries contain materials, components and substances that can be harmful to you and your environment, as long as the waste materials (waste electrical and electronic equipment and batteries) are not managed correctly. Electrical and electronic equipment and batteries are marked with the crossed out bin, as shown below. This symbol means that old electrical and electronic equipment and batteries should not be thrown away; they must be removed separately. As the end user, it is necessary for you to deliver the exhausted batteries to the appropriate collection points.
