How long can an electric bike remain stationary?

You’ve invested in a beautiful e-bike and are enjoying every kilometer of the smooth ride. But now winter is coming, you’re going on an extended vacation, or you’re simply putting your bike aside for a while. One question I see come up very often is: How long can an e-bike actually sit unused without being damaged?

The short answer? An e-bike can easily sit unused for several months, as long as you take the right precautions. But if you don’t handle it properly, the battery—the beating heart of your bike—risks suffering irreversible damage. At Upway, we give electric bikes a second life every day, and we know batteries inside and out. In this article, I’ll explain exactly how to best protect your electric bike during a long period of inactivity.

Key Points

• A few months of inactivity? No problem: an electric bike can easily go a few months without being used, but if it goes more than 6 months without maintenance, the risk of damage becomes serious.
• Avoid deep discharge: Even when the device is turned off, the battery management system (BMS) consumes a small amount of power. Charge the battery to between 50% and 70% before storing it.
• Don't forget the rest of the bike: make sure to inflate your tires properly tires prevent deformation, and charge the battery to 100% before your first ride to rebalance the cells.

What happens to your battery during prolonged inactivity?

Your e-bike's battery is a marvel of technology. When you don't use it for an extended period, several processes begin to take place. The key thing to remember: a battery discharges even when it's not in use.

This is due in part to the battery management system (BMS). This smart system constantly monitors your battery’s health, but does so by consuming a tiny amount of energy. If you store the battery when it’s empty, or if you don’t check it often enough, the voltage level will eventually drop to a critical threshold—this is known as deep discharge. This can cause lasting damage to the cells, leading to a loss of capacity and a significantly reduced range. Wondering if your bike is already experiencing a malfunction? Our article on troubleshooting battery issues on an e-bike will help you figure it out.

Temperature also plays a huge role. Storing a battery at sub-zero temperatures damages the chemical composition of the cells.

At what point is it "too long"?

You can safely leave an e-bike battery unused for a few months, provided you store it properly. But if your bike remains unused for more than 6 months, you enter a risky zone and risk a significant loss of capacity. Some modern batteries switch to “sleep mode” during prolonged inactivity, but periodic checks are still essential. To help you prepare for this period with peace of mind, our guide to preparing an electric bike for long-term storage details each step.

Best and Worst Practices for Storing Your Electric Bike

Want to get the most out of your battery’s 5- to 8-year lifespan (or 500 to 1,000 charge cycles)? Follow these golden rules. To learn more, find out what else affects the lifespan of an electric bike.

What to Do

• Charge the battery to between 50% and 70%: this is the ideal range for storing a lithium-ion battery over the winter. Some brands, such as Gazelle, recommend a range of 30% to 70%, but around 50% is always a safe bet.
• Store it at room temperature: remove the battery from the bike and keep it indoors in a dry place at a temperature between 10°C and 20°C.
• Unplug and remove the battery: Be sure to do this every time, especially if the bike itself is stored in a cold garage or shed. Our article on removing the battery from an e-bike provides all the tips you need.
• Check every two months: take a look at the charge level. If it gets too low, give it a quick recharge.

What You Should Definitely Avoid Doing

• Storing a battery when it's completely dead is the quickest way to cause severe deep discharge.
• Leaving the charger plugged in all the time: Keeping the battery at 100% all the time is harmful to modern lithium batteries and accelerates wear and tear.
• Leaving it in a damp, cold place: moisture and freezing temperatures are your battery's worst silent enemies.

What most people forget during a long break

There's a lot of talk online about the battery, but what happens to the rest of your e-bike if it sits unused for months? Here are two essential tips that are often overlooked:

1. Avoid "tires "

When a heavy e-bike (often weighing more than 25 kilos) is left in the same spot for months, its entire weight rests on a single small portion of tire. If the tire pressure gradually drops, the rubber can become permanently deformed—this is known as “tires ” or “flat spots.” Inflate your tires the maximum recommended pressure before storing the bike, or better yet, hang it on a wall mount so the tires longer touch the ground.

2. Balancing the BMS to 100% before the first spring outing

We now know that a battery should be stored at a charge level between 50% and 70%. But be careful: when you take your bike out after several months, it’s essential to fully recharge the battery to 100% before your very first ride. During storage, the individual cells in the battery may become slightly out of sync in terms of voltage. The BMS corrects this by rebalancing the cells, but in many systems, this rebalancing doesn’t occur until the very end of the charging cycle. Not sure if the charging process went smoothly? Find out how to reset your e-bike’s battery if necessary.

refurbished durable and reliable

Did you accidentally leave your dead battery out in the winter cold for too long, causing its range to drop significantly? Having the battery reconditioned is often a smart and more cost-effective solution.

Are you looking for a fresh start? Choose a refurbished e-bike refurbished Upway. Our professional mechanics inspect every bike (and its battery!) based on dozens of criteria. That way, you get the quality and peace of mind of a new bike—at up to 60% off.

Frequently asked questions

1. Should I leave my battery plugged in when I'm not using my bike?

No, this is strongly discouraged. Charge the battery to between 50% and 70%, unplug it, and store it at room temperature. Plug it back in briefly every two months for a top-off charge if necessary.

2. What is the average lifespan of an e-bike battery?

With proper use and maintenance, a bike battery lasts an average of 5 to 8 years, or about 500 to 1,000 full charge cycles. After that point, the battery is generally not defective, but you will notice that its range decreases significantly.

3. Can I leave my electric bike outside or in a cold shed during the winter?

The bike itself (frame and mechanical parts) can be stored in a cold or dry shed, as long as it stays dry. The battery, however, must always be removed and stored indoors at room temperature (10°C–20°C).

4. Does a battery also lose capacity when the bike is not in use?

Yes. Even when not in use, the battery management system (BMS) consumes a small amount of power, and natural self-discharge occurs. Without recharging, the battery will eventually drain completely, leading to a damaging deep discharge.

5. What exactly is deep discharge?

Deep discharge occurs when the voltage level of the cells drops too low—for example, after a prolonged period of inactivity without recharging. It almost always results in permanent damage to the battery and a significant loss of capacity. So be sure never to leave your battery at 0% for months on end in some corner!
