How to use the electric bike?

1. Switch on the bike
Turn on the bike by pressing the on/off switch on top of the panel to the left of the handlebars. The bike must be switched on before you start riding. While riding, you can regulate the desired engine power by pressing "+" or "–" on the panel.


2. Ensure that the bike has electricity
You can check that the bike is charged by turning on the bike. The battery percentage is then shown at the top of the display.


3. Charging while the battery is in the bike

The bicycle can be safely charged while the battery is in the bicycle. You then simply plug in the charging cable under the hatch between the pedals. When charging the battery, it is important that you always connect the charger to the battery or e-bike before plugging the charger into the wall. If the charger is in the socket when you connect the battery or electric bike, it may not want to charge.


4. Remove the battery
When you want to take out the battery to charge it inside, do as follows: Insert the key into the battery lock on the front right side of the bike, turn the key clockwise, the battery will fall forward a little, then press the button on the top of the battery to release it completely.


5. Charging the battery outside the bicycle

Once you have removed the battery, it can be charged by plugging the charger directly into the battery. Charging time can vary from two to four hours depending on how full the battery is.

 Your safety is important to us. Here are some reminders regarding battery-safety.

  • Do not start charging the battery if it is visibly damaged.
  • Stop charging immediately if you experience a strange smell or see smoke.
  • Keep an eye on the battery, and do not charge it while you sleep.
  • Avoid damaging the battery by allowing it to fall to the floor of taking hits.
  • Do not place the battery in the sun while charging.
  • Do not cover the battery and charger, or place objects near them. Be vigilant about flammable materials.
  • Do not allow the battery to come in contact with water or open fire.
  • Keep the battery away from children and pets.
  • Do not use the battery or charger for other gadgets.
  • In the unlikely event that the battery catches fire, do not attempt to extinguish the fire with water. Evacuate the area and contact emergency services immediately.
  • When you are at home, store the battery in the bike. When you are out, take the battery with you to avoid theft. 


6. Use of gears
Although this is an electric bike, it is important that you use the gears. This gear is stepless. You shift by turning the handle furthest in on the right side of the handlebars. You use the gears in the same way as when you ride a normal bike without an engine. This means that when you enter a hill, it's a good idea to engage a lighter gear. Avoid shifting while pedaling as this exposes the wire to high wear - especially when shifting to a higher gear.

ATTENTION: Before riding, it is important to ensure that the luggage tie is tightened well so that it does not come off the luggage tray. In the worst case, the rubber band can enter the wheel and damage the gear.

How to park and store the e-bike

In order to be covered by our insurance agreement, it is a prerequisite that you park the bike correctly.

E-bike theft is unfortunately very common, and by following these guidelines you reduce the likelihood of theft considerably. If you have followed our insurance terms and guidelines for parking, you will be covered by the insurance in the event of theft, but we cannot, however, guarantee that you will get a new bike immediately.

Guidelines for parking the bicycle

Bicycle lock: It is important to use the supplied bicycle locks to be covered by our insurance agreement. On the bicycle, there is a wheel lock that locks the rear wheel. This must be used every time. Put the key in the lock on the right, turn a quarter of a turn clockwise and press the lock lever on the left down.

In addition, you have a chain lock located under the seat. This is used as a supplement to the wheel lock to secure the bicycle to a structure. Thread the chain around a structure, insert the locking pin through the ring on the chain, and fasten the locking pin into the wheel lock on the left side. It is the same key that is used for the lock and battery.

Battery: If you park on public property (on the street, in the city and other places without access control) without having the bicycle under supervision, we recommend that the battery be removed immediately. If someone steals the battery while the bike is parked unattended, it is not necessarily covered by the theft insurance for the bike, and you (as the renter) will in these cases be responsible for replacing the battery.

The keys to the battery and bike lock are in the bag when you receive the bike. It can be useful to separate these two keys so that you have a spare if you lose one of the keys. Also remember to take the keys out of the lock when you park the bike.

Parking at night: Parking the bicycle on public land (in the city, street etc.) overnight should be avoided, as the probability of theft increases considerably. We recommend keeping the bike locked up at night if possible (for example in a shed, closed backyard or in an apartment).

If you store the bicycle in a shed, there are requirements for the quality of the lock for the theft insurance to be valid. If you are in doubt, we also recommend locking the e-bike with the bike lock.

The terms of the theft insurance are described in detail under Rental terms and conditions.


How to take care of the electric bike

1. Air in the tires
One of the most important things you do to take good care of your bike is to have enough air in the tires. For frequent use, we recommend checking the tires once a week. On average, you should expect to fill the tires with air around once a month. Recommended pressure for the supplied tires is 3.5 bar and maximum pressure is 5 bar.

2. Belt care
Your e-bike is equipped with a belt drive. Belts are extremely durable and have a long life. The belts are cleaned with water. Do not lubricate with oil or grease (to prevent dirt from sticking).

The e-bike will last longer if it is kept clean. For a normal wash,  water and a cloth is sufficient, and if it is particularly dirty, you can use a little dish-soap and a regular scrubbing brush. The garden hose can also be used, but do not use a high-pressure washer as it can push water into the electronics, ball bearings and motor.
