Electric bicycles

The battery can be charged in two ways: installed on a bicycle or taken out of the bicycle and charged in a suitable place.

The battery does not charge by pedaling while riding the bike. This technology is common in cars.

One of the more common questions when charging batteries is how long it takes for the battery to fully charge. Charging speed is affected by battery capacity and charger power (2A, 4A, 6A). In most cases, the battery does not charge from 0% do 100%, as the battery can usually be charged before it is completely discharged. Li-ion Econo batteries do not have a memory effect, which means that it does not matter at what charge you charge the battery or turn here.

How long is the battery life or how many charge cycles does it carry?

Its lifespan depends on the handling or storage method of the battery, but its average estimated lifespan with normal use is 5-7 years. After 500 full charge cycles, its capacity is expected to drop to 80-90%. Read more about battery life here

The engine is operated by controls on a screen attached to the handlebars. Using on-screen commands, you can set different support modes, monitor speed and other functions.

It usually has 4-6 levels of help.

Legislation for electric bicycles stipulates that motor support of up to 25 km/h is legally permitted.

Yes we have to invest a little more energy in pedaling as the engine shuts down and we only drive the bike with our own energy. The difficulty also depends on the type of engine, because some types of engine brake when we reach a speed of 25 km / h, and some do not.

The range itself depends on the following factors: battery capacity, engine power, level of assistance, outside temperature, slope inclination and the own power we put into turning the pedals. If we take e.g. 500Wh battery, can be reached in the first level of assistance, on flat terrain at an ideal temperature (20 degrees Celsius) approx. 70-80km. If we take the same battery and use it in the highest level of assistance and drive uphill, we can reach approx. 40-50km. Read more about battery range here.

We clean it like an ordinary bicycle with water and detergent, but if we use a high-pressure washer then we must clean it from a suitable distance, so as not to wet the components and destroy the electronics.

The weight of electric bikes ranges between 20kg and 25kg depending on the model. The weight of the battery is approx. 3.5kg.

We transport the electric bike the same as a regular bike with the proviso that we recommend removing the battery to relieve the bike carrier.

It is possible to buy a chip that is built into the bike and thus removes the speed limit at 25km / h. Once this is done, the electric bike becomes a motorcycle and needs to be homologated and registered in order to be used in road traffic. You do not need type-approval and registration if you use it on private land outside of public road transport.

Are there engines that support different driving modes?

Engine power is adapted to the driving style. For trekking, touring and city driving we use engines with lower power, which is approx. 40nm-60nm because we basically don’t need a stronger ones. With less power, we have less consumption and thus more range.For mountain bikes we use engines with higher power, which is approx. 70nm-90nm, as their purpose is to overcome slopes and paths of higher altitudes and easier weight transfer.


For optimal life of Li-ion batteries, it is recommended to use when the battery status is between 30% and 80%. It is recommended that you fully charge the battery the first time you use it (if this has not already been done by the dealer) or when the battery has not been used for a long time.

Yes. However, it is recommended that the charger is removed from the outlet and from the battery after charging is complete.

How much Ah the battery has gives us information about the nominal capacity of the battery or the amount of stored electricity. Example: One 14Ah battery can provide us with 1 A of electricity for 14 hours.

Wh denotes the energy stored in the battery. One watt hour corresponds to the work done by a 1 W consumer in 1 hour. Watt hours can be calculated by multiplying the nominal capacity by the nominal voltage (example: 14 Ah x 36 V = 504 Wh).

If the e-bike or battery is not used for a long time, it is recommended that the battery be charged between 30% and 50%. Before the next use, it is advisable to fully charge the battery.

It is recommended to store e-bike batteries in a dry, cool place, but without the possibility of freezing. The optimum temperature for storing the battery is 10 ⁰C (for example: the battery can be stored in a dry place in the basement).

Yes, but it is important that the battery and charger do not come into contact with moisture and water, and that there is no exposure to the sun. To protect the battery cells, the charger will not charge when the temperature is below 10 ° C.

The average lifespan of Li-ion batteries is between 4-6 years. However, this number may vary depending on the method of maintenance, charging, frequency of use, etc.… If the battery is charged with partial cycles, the service life can be extended.

If you have any questions about removing the battery, you can contact our dealers.

The liquid must never come into contact with the skin, and such batteries must no longer be charged or used.

Damaged batteries should not be charged, and damaged chargers should not be used for recharging. In case of damage, it is best to contact the seller, who will be able to advise you accordingly.

Dirt should be removed from the battery and charger with a dry cloth.

The optimum operating temperature is +20 ⁰C. As a result, the battery should not be stored or charged outside during the winter months.

The electric bike usually operates reliably at a temperature of 0 ⁰C to 45⁰C. Temperatures between 10⁰C and + 50⁰C are allowed during battery discharge.

Self-sufficiency in energy

The lifespan of solar cells is about 30-40 years. During this time, most systems require almost no maintenance other than cleaning (dust, leaves, snow). Their lifespan generally depends on the quality of the solar cells used and the quality of the entire installation. Annually, solar cells lose about half a percent of their total capacity. After 25 years of operation, quality solar cells will still operate with almost 90% efficiency.

The amount of electricity produced by solar cells depends on three factors:

  • efficiency of solar cells,

  • solar cell installations and orientations;

  • amounts of sunlight,

which comes directly to the installed surface of the solar cells. We will help you choose the capacity of the solar system according to your consumption or electricity needs.

How does shadow affect the functioning of the solar system?

It is important to reduce shading because solar cells operate at optimum power when their entire surface is fully exposed to direct sunlight. The system will still produce energy if it is in the shade, but energy production will be reduced.

Is solar system maintenance required?

Once the solar system is installed, it does not need to be maintained. We recommend that you periodically clean the solar cells and visually inspect the system. In this simple way, you will ensure their good functioning.

The solar system works on sunlight, not heat. In winter, there may be less sunlight, so electricity production is lower.

Yes. Solar collectors and converters are designed to withstand exposure to the weather. They tolerate exposure to extreme weather conditions, including rain and strong winds. The solar cells can withstand a certified nominal load of 5400Pa, which is equivalent to a 25mm thick hailstone falling at a speed of 83km / h. However, it is recommended that you protect your solar cells.
