The benefits

Reasons to choose eBike batteries from Bosch

No memory effect

Bosch batteries with lithium-ion cells can always be charged even for a short time if desired, regardless of their charge level. Interruptions in the charging process do not harm the batteries. Complete discharge is not necessary.

 

Very low self-discharge

Start-up is possible without recharging the battery even after prolonged storage, e.g. during the winter. For longer storage, a charge level of approx. 30 to 60% is recommended. Charging is also recommended after an extended storage period.

Long service life

Bosch batteries are designed for many trips, miles and years of service. The intelligent electronic Bosch Battery Management System (BMS) protects against excessive operating temperatures, overloading and deep discharge. The BMS checks every single cell and thus makes the battery even more durable.

Rapid charging

Bosch Chargers are available in various sizes and power levels and allow quick charging as needed.

Easy to remove

A few simple steps are all it takes to remove a Bosch battery. The battery can therefore also be charged or stored away from the eBike. Among other things, this makes use in winter easier. Since the battery delivers less power at low temperatures, it should be stored at room temperature in winter until shortly before the ride.

Competent service

Whether for personal advice, regular software updates, service requests or comprehensive all-round checks: together with the dealer's eBike experts, we make sure you enjoy a special riding sensation.

Safety

With a combination of various technological safety mechanisms, additional tests, and a high degree of automation in production, Bosch sets standards in battery safety.

Operating principle of a lithium-ion battery

A lithium-ion battery generates electromotive force by displacing lithium ions. When riding, the electrons migrate from the negative anode via the drive unit to the positive cathode. The lithium-ions are responsible for balancing. When charging, the reverse process takes place.

Tips and tricks to maximize range

Cadence

Cadence

Cadences above 60 rpm optimize the efficiency of the drive unit. In contrast, very slow pedaling costs the battery more energy, especially in high gears.

Weight

Weight

The weight should be minimized so that the total weight of the bike and load are not unnecessarily high.

Starting & braking

Starting & braking

Just like with a car, frequent starting and braking are less economical than riding long distances at a steady speed.

Gear shifting

Gear shifting

Correct gear shifting also makes riding more efficient: It is best to start and climb hills in low gear, shifting up according to the terrain and speed. The computer provides shift recommendations for this.

Tire pressure

Tire pressure

The rolling resistance can be minimized by the correct tire pressure. Tip: In order to maximize the range, inflate the tires to the maximum permissible tire pressure.

Motor performance indicator

Motor performance indicator

Monitor the motor performance indicator of the Intuvia, Kiox or Nyon computer and adapt your riding style accordingly. A long bar means high power consumption.

Battery & temperature

Battery & temperature

As the temperature falls, the performance and range of a battery is temporarily reduced, as the electrical resistance increases. Therefore, in cold temperatures, a temporary decrease in the usual range is to be expected.

Care and use

Care and use

The service life of a Bosch eBike battery can be optimized with the right handling and care. For this, the instructions for cleaning as well as for storage when not in use for a longer period of time must be taken into account.

Tip: The plug connections should be occasionally cleaned and lightly greased.

Handling, care and transport

Charging on the eBike

PowerPacks and PowerTubes are particularly easy to charge directly on the eBike itself. You just need to plug the charger's charging plug into the charging socket in the battery mount and the power plug into the wall outlet. Done. Charging should be carried out in a dry environment and at room temperature with an installed smoke detector.

Removal and insertion

The Bosch batteries are seated securely in their mounts even when riding on uneven terrain. However, they can be removed quite easily for storage or charging: Simply open the lock and remove the battery from the mount.

Bosch batteries can also be reinserted just as easily and intuitively thanks to their low weight, handy dimensions and the precise fit of the battery and mount. The battery engages positively in its holder and thus sits firmly in the frame or on the eBike.

Handling

The Bosch battery is an important eBike component. Its service life can be optimized with proper handling and care.

Cleaning & care

A damp cloth is suitable for cleaning the battery. Plug connections should be occasionally cleaned and lightly greased. The battery must be removed each time before the eBike is cleaned. To protect the electronic components, the batteries must not be cleaned with direct water jets or even high pressure.

Storage during winter

Store batteries in a dry place at room temperature. Fully charged and fully discharged mean more stress for the battery. The ideal charge level for extended storage periods is
approx. 30 to 60% or two to three illuminated LEDs on the battery display.

Winter use

During winter use (particularly below 0 °C (32 °F)) we recommend charging and storing the battery at room temperature before inserting the battery in the eBike immediately before riding it. For longer journeys in the cold, it is recommended to use thermal protection covers.

Transport

Lithium-ion batteries store large amounts of energy. Therefore, some precautions must be taken during transport. Ideally, the battery should be discharged to approx. 30% before transport and only fully recharged at the destination.

Travel by car

If the eBike is transported with a bike carrier, the battery must be removed beforehand and stowed safely in the car.

Travel by air

The International Air Transport Association (IATA) has banned the transport of eBike batteries on passenger aircraft. We recommend renting a Bosch eBike battery at your destination. Check in advance whether the airline transports eBikes without a battery.

Travel by train

In trains with bicycle compartments, most eBikes can usually be taken along without complications. An extra bike ticket and space reservation for the eBike are often required. The eBike battery must remain securely mounted during the journey and must not be charged. Before starting your trip, you should ask the respective service provider about the exact transport conditions. In some cases, it is not possible to take eBikes on all routes.

Travel by local public transportation and long-distance bus

In local public transportation systems, for example, light rail services, it is often possible to purchase a bicycle ticket to take eBikes on board outside of the regional blocked periods. It is advisable to check with the respective transportation authority before traveling. The transport of eBikes on long-distance buses is regulated differently depending on the provider. Here you should inquire in good time before starting your journey.

Good to know

eBike batteries are hazardous goods and can't be sent in the post. Taking your eBike battery on the plane is also not permitted.

▶ Tip: If you can't take your eBike with you, simply hire one at your destination.

Service life

The service life of Bosch batteries is mainly influenced by the type and duration of use. Like any lithium-ion battery, a Bosch battery ages naturally, even when it is not used. It loses capacity over time.

Factors that shorten the service life:

  • Heavy-load use

  • Storage above 30 °C (86 °F) ambient temperature

  •  Prolonged storage in fully charged or fully discharged state

  •  Parking the eBike in direct sunlight

  • Regular complete emptying of the battery when riding

Factors that extend the service life:

  • Low-load use

  • Store and charge the battery at moderate temperatures – ideally at room temperature

  • The ideal battery charge level is between 30 and 60%

  • Parking the eBike in the shade or a cool location indoors

 

Sustainable use of raw materials

Recycling

The carbon footprint of an eBike is largely determined by the production, use and recycling of the battery. The longer an eBike is used and the more trips with other modes of transportation it replaces, the better for the environment. To ensure that valuable raw materials can be reused at the end of its service life, the battery must be recycled properly.

The BMS protects against excessive operating temperatures, overload and deep discharge. It checks every single cell and thus makes the battery even more durable.

FAQs on rechargeable batteries

Everyone can hand in their old or defective eBike battery free of charge at any bicycle retailer, who will forward it for environmentally friendly recycling. You do not need to purchase a new battery to use this service.

Please note that you should not touch severely damaged batteries with your bare hands, as electrolyte can leak out and cause skin irritation. Please store them in a safe place outdoors with the contacts taped off and take them to an approved bicycle retailer for proper disposal as soon as possible.

The mount is designed in such a way that water can drain off and the contacts can dry. To ensure that this happens, the mount and plug area should be kept clean. The contacts have a coating which protects the surface against corrosion and wear. Terminal greases or technical Vaseline may also be used if required.

Bosch chargers are adapted specifically to the Bosch eBike System and have the correct software for charging and managing the Bosch rechargeable battery efficiently. Using a different charger may reduce the service life of the rechargeable battery or cause other damage or malfunctions in the eBike system.
