We have compactly collected the most important questions and answers around the subject of E-bikes for you in our FAQs.
What is the difference between an E-bike and a pedelec?
Colloquially, the term E-bike has become established for all electrically powered or supported bicycles. However, there is a difference between a classical E-bike and the pedelec: Most of the currently trendy bicycles with pedalling support are pedelecs. This drive type is called by an acronym for "Pedal Electric Cycle". The rider must pedal, and the motor will provide the desired support. Initially, only electric bikes with a drive output up to 250 Watt were classified in this category. By now, there also are some faster pedelecs up to 45 km/h, such as the BULLS Green Mover E45, from the S- or Speed-pedelec class. A classical E-bike, in contrast, is a cycle with a drive that does not require pedalling. This really is an electrical moped in which a turning handle controls the electrical thrust.
How does weather affect E-bike operation?
Generally, the technology is cold-resistant. However, low temperatures will limit the performance of the rechargeable battery considerably. The reach will reduce a lot at low temperatures. The ideal storage and charging temperature for rechargeable batteries is between 10 and 20 degrees. Much lower temperatures may damage the rechargeable battery when charging.
How do E-bike and battery get through the winter?
If you do not use your new E-bike year-round, you should remove the rechargeable battery at the end of the season and wash the bike thoroughly. Once it is fully dried, spray it with a wax spray. Ideally, you should put it into a dry room at a constant temperature. Charge the battery to 50 - 70 percent and store it dry and frost-free. Take the charger out of the socket. Make a note in your calendar that you need to recharge the battery to 50 - 70 percent again in the first week of January. Also take that opportunity to pump the tyres on your bike. Wake your E-bike from its hibernation to take it on new adventures in spring.
Is interim charging bad for the battery?
Once, there were concerns about the "memory effect". Incomplete charging of a rechargeable battery would reduce its charging capacity. Thanks to modern lithium ion technology, this problem has, however, long been a thing of the past. Specifically for E-bikes, experts now even recommend interim charging, which can increase your range considerably within just an hour or two. You can use your lunch break during a long E-bike tour this way, for example. Remember that you may need a plug adapter when E-biking abroad.
How can the E-bike be transported?
You can transport your E-bike like any normal bicycle. Since the E-bike is slightly heavier, a rear carrier is much preferable to the roof rack for transporting it by car. Take off the rechargeable battery and keep it separately in the boot of your car.
How expensive is charging the rechargeable battery?
Depending on the electricity price and size of the rechargeable battery, the costs for one charge are about 8 – 10 cent. This amounts to about 10 cent per 100 kilometres.
What values will tell me about the capacity of my rechargeable battery?
First, the voltage (Volt) is decisive. It is either 26 V (older models), 36 V or 48 V. Furthermore, the ampere hours play a role (8 Ah, 10 Ah, 11 Ah, 12 Ah, 15 Ah, 17 Ah, …) The capacity of a rechargeable battery is determined by multiplying the two. The resulting product is the stored energy, which can be considered a comparison value, e.g. 36 V x 11 Ah = 396 Wh.
What factors determine the range per rechargeable battery charge?
There are many factors that play a considerable role for the range. Of course, the topography is decisive, i.e. the share of up- and downhill sections of a tour. The tyre pressure the rider uses affects the maximum range, as does the total weight. The different drive systems usually offer different support intensities. The higher the degree of support, the shorter the range. Other factors include the weather and the chosen gear. Recuperation solutions (energy recovery; NOT for mid-mounted motors) can increase the range as well. The manufacturers' information is generally to be considered reference values only. The average range with current systems amounts to approx. 80-100 kilometres.
How long will my rechargeable battery "live"?
Today, most E-bikes available on the market use lithium-ion-rechargeable batteries. This type of rechargeable battery is more environmentally compatible and lighter in weight than, e.g., lead-based rechargeable batteries. It also has a high storage capacity of up to 180 Wh/kg. The once-feared memory effect is a thing of the past. The rechargeable battery may and should be charged even if it has not been fully depleted yet. The common manufacturers specify that the rechargeable battery can go through approx. 700 to 1000 complete charge cycles before a relevant and noticeable range loss will occur. Observe that charging 50 percent means only half a cycle. Based on an average range of 80 kilometres, the total range will be 56,000 to 80,000 kilometres.
How and where can the rechargeable battery be charged?
It is particularly important that only the original charger is used. Usually, the rechargeable battery can be charged without removing it from the bike. Most models permit removing the rechargeable battery from the bike for separate charging as well. The optimal charging temperature is at 10-20 degrees. It is generally advisable to keep the rechargeable battery in heated residential rooms for charging and storage.
