eBike Batteries
Whether you're a long distance cyclist or enjoy regular shorter rides, understanding the different types of ebike batteries is essential for optimizing your cycling experience. The range of your electric bike depends on several factors, including rider weight, terrain, weather, and, most importantly, the type of battery. Curious about how far you can ride and which battery is right for you? Read on to discover everything you need to know about ebike batteries.
What types of ebike batteries are available?
Batteries for electric bikes come in a variety of shapes and sizes. The Bosch Li-ion batteries we spec are measured in watt-hours or "Wh". Watt-hours are used to describe the amount of power a battery produces in watts over the course of an hour. The battery on a Gazelle ebike can range from 400Wh on the Medeo T9 City up to a 625Wh battery on the Ultimate C380 or T10 Smart System.
Where is the battery of an electric bike located?
On a Gazelle ebike the battery is located on the downtube of the bike, either on the frame or integrated into the frame. Select models manufactured in 2022 feature a rear rack battery located under the rear rack. The battery and motor on an ebike account for much of the overall weight aside from the frame. The location of the battery effects the bikes center of gravity which influences how the bike handles. eBikes with these components centered and low on the frame or balanced well can lend to a more stable riding experience. All Gazelle ebikes can be plugged in to charge or you can remove the battery to charge off the frame.
Different battery locations
)
Under the rear rack
Some ebikes have a battery placed under the rear rack. In North America, you can only find this style on the 2023 models of the Medeo T9 and the Medeo T9 City. Aesthetically, this can be enticing to those who prefer the look of a regular bike. The battery being in the rear rack means it's concealed without adding visual weight to the frame.
With this battery, the weight of the bike is placed a little further back than models with the integrated battery or downtube battery.
)
In the frame
A battery integrated into the frame is a seamless and clean look. The weight placed in the middle of the bike ensures optimal road handling plus an integrated battery can be a theft deterrent as it more difficult to remove from the frame without the key. You can find the integrated battery either on the top or bottom of the frame. This battery can be removed to charge or you can plug in the bike to charge it on frame.
A drawback to this type of battery is in order to properly reinforce the frame extra material is required, meaning the weight and cost of the ebike can increase a little.
)
On the frame
The on tube battery is offered on the 2024 Medeo T9 and Medeo T9 City in North America. With the battery placement low and centered on the frame, ebikes with this battery have great stability.
Visually this battery is more noticeable on the frame than the integrated or rear rack batteries.
Removable batteries
A removable battery is a convenient and useful feature. Don't have an outlet near your bike storage area? Easily remove the battery from the ebike using the same key as the cafe lock to charge the battery elsewhere. Plus, removing the battery from the bicycle can drop 8-9lbs (3-5kgs) off the total weight, helpful for when you need to lift the bike onto a car rack.
How long does it take to charge an ebike battery?
Depending on the size of your battery, it will take up to 4 hours to charge. Most of the charge will come up within the first 1-2 hours then slows down to preserve the battery quality as it reaches a full charge.
What is the lifespan of an ebike battery?
Bosch estimates their batteries last about 10 years or 1,000 charge cycles. They are under warranty for 2 years or 500 charge cycles.
How you use your battery has a huge influence on its lifespan. The correct maintenance of a battery is crucial to getting the most out of this component. Make sure to read the manual of your electric bike carefully. That way you know exactly how to get the most out of your bike's battery!
