- What is the battery range?
In normal conditions, an electric bike battery at full charge has an average range of 60 km. This of course depends on the motor power, the rider’s weight and the conditions of use of the bike. The range of an electric bike also depends on the quality of the battery.
- Is an electric bike heavier than a conventional bike?
The weight of an electric bike is generally between 20 and 25 kg. The extra weight compared with a conventional bike is about 6 kg. Although the e-bike is heavier than a traditional bike, this does not bother the rider, thanks to the electric assistance that amplifies the energy generated when pedalling.
- Can the e-bike be ridden when the battery is flat?
Electric assistance does not alter the way the bike works. When the battery is flat, the e-bike behaves like a conventional bike: simply pedal to move forward. However, pedalling an electric bike with a flat battery requires more physical effort, since the e-bike is heavier than a conventional bike.
- How do I choose the electric bike battery?
The higher the battery voltage, the more powerful the e-bike. The higher the amperage, the longer the range. To guarantee the durability and performance of your electric bike, choose a battery of at least 36 V and 8 Ah.
- Can a conventional bike be converted into an electric bike?
Yes, provided the bike is sturdy enough to carry the weight of the battery and the electric motor. Electric bike conversion kits are sold on the market and are available in different power ratings. However, fitting an electric kit to a conventional bike requires some knowledge of electricity.
