Questions and answers about FLYER e-bike batteries
All FLYER e-bikes are equipped with high-performance batteries that contain specially developed cell types for use with e-bikes. They offer an ideal balance between capacity, performance, weight and service life. The special feature of lithium-ion batteries is their particularly high energy density. This means they can store more energy and are relatively low in weight.
FLYER SIB-630 battery
The large FLYER Smart Integrated battery (630 Wh) provides plenty of energy for long tours that cover great differences in altitude.
The SIB-630 battery is partly integrated into the frame and boasts ideal battery handling, with it being exceptionally easy to remove and insert into the frame.
FLYER STB-750 or STB-630 battery
The high-capacity FLYER seat tube batteries with 630 Wh (STB-630) or even 750 Wh (STB-750) are what make our FLYER e-bikes frontrunners when it comes to range and altitude. The battery can be charged on the bike itself or easily removed. The large grip area makes for simple handling.
Some of our FLYER e-bikes are fitted with Bosch eBike Systems drive systems. More information about Bosch eBike Systems batteries.
Charging the e-bike battery
You can charge the battery separately or directly on your FLYER e-bike at any time without shortening the service life. Interrupting the charging process doesn’t damage the battery. FLYER and Bosch batteries are characterised by long energy storage with no memory effect.
The charging time depends on the battery capacity. Our Bosch PowerPack 500 battery can be half charged after 1.5 to 2 hours, for example. You’ll need a maximum of 4.5 hours to fully charge the battery.
A battery management system is integrated into the FLYER battery to protect the battery against overcharging, undervoltage and overheating. Single cell monitoring ensures safe, reliable and gentle charging.
Storing the battery
If the bike is going to be stored for a longer period of time, e.g. over the winter, we recommend that you charge the battery to a charge level of 40-60% and store it in a dry location at room temperature. At this charge level, the battery charge level display will show three full bars. Check the charge level after 6-8 weeks at the latest and charge the battery accordingly if necessary.
Performance and range
No, batteries are only compatible with their product line and should not be used with other models or brands.
In principle a battery loses approximately 10% capacity per year. However, the exact service life cannot be predicted as this depends on the nature and duration of the demands made of it. We recommend switching to a new battery after approximately 4 to 5 years.
Following simple rules for protection, transport and correct storage can have a positive impact on the service life of a battery.
Keep your e-bike battery in a dry environment and protect it from direct sunlight. A room temperature of 15 to 20 degrees Celsius is ideal for storing your battery. The battery should also be charged at room temperature. When transporting your e-bike, it is best to remove the battery and store it safely in your car.
The range depends on a large number of factors so an exact prognosis isn’t possible. The size of the battery, the power of the motor and the assistance level selected have the biggest impact on the range. However, the topography, surface, pedal frequency, tyre pressure, outside temperature and total weight, for example, are also important. The Bosch e-bike system range assistant gives you an overview of the different influences of various factors on the range.
The cold reduces a battery’s performance. You should ideally store your e-bike battery at room temperature in the winter and attach it just before the trip.
If you’d like to test the performance of your e-bike battery, ask your FLYER dealer.
Cleaning and disposing of e-bike batteries
Remove the battery before you clean your e-bike. Try and keep water out of the battery compartment. If needed, you can get protective caps for the battery compartment from your FLYER dealer in order to prevent direct contact with dirt and water.
You can clean the battery with a damp cloth when required. Avoid using strong detergents as these may damage the surface.
Faulty batteries cannot be repaired. If you think that your battery is no longer working, let a FLYER specialist retailer check it. They will establish if the battery really has a defect or if there is some other problem.
Bring your e-bike battery to your FLYER dealer. S/he will check if the battery really has a defect or if there is some other problem. If your battery has a defect, your FLYER dealer will dispose of it properly. You already paid to have the battery disposed of when you bought your battery.
