Long service life

Bosch batteries are designed for lots of trips, miles and years of service. The intelligent, electronic Bosch battery management system (BMS) protects against excessive operating temperatures, overload and deep discharge. The BMS checks every cell, extending the life of the battery.

Battery level icon

Rapid charging

Bosch chargers are available in a range of different sizes and performance levels, and enable rapid charging according to your needs.

eBike icon with an arrow pointing towards it

Easy to remove

Bosch batteries can be removed in just a few simple hand movements. The battery can therefore be charged and stored away from the eBike. This simplifies use, for example, when using in the winter. As the battery delivers less power at low temperatures, in winter it should be stored at room temperature until shortly before starting the journey.

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. The entire Bosch eBike system is certified to UL 2849, which is a standard covering the electrical system of eBikes powered by a lithium-based, rechargeable battery. 

How a lithium-ion battery works

A lithium-ion battery generates the electromotive force by displacing lithium ions. While the eBike is in motion the electrodes move from the negative anode, via the drive unit, to the positive cathode. The lithium ions provide balance. The reverse process takes place when the battery is charged.

Tips and tricks for longer riding fun with the range calculator

Cadence

Cadence

Cadences above 60 revolutions per minute optimize the efficiency of the drive unit. Very slow pedaling, especially in high gears, on the other hand, costs the battery more energy.

Weight

Weight

Weight should be minimized by keeping the total weight of the bicycle and luggage from being unnecessarily high.

Starting & braking

Starting & braking

As with a car, frequent starting and stopping is less economical than long distances at almost constant speed.

Shifting system

Shifting system

Correct gear shifting also makes eBiking more efficient: A low gear should be used when starting and on inclines, followed by upshifts according to the terrain and speed. The computer provides shift recommendations.

Tire pressure

Tire pressure

Rolling resistance can be minimized by 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 with the motor performance indicator of the Intuvia, Kiox and Nyon computers and adapt your riding style accordingly. A longer bar indicates a higher power consumption.

Battery & temperature

Battery & temperature

With decreasing temperature, 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

With the correct handling and care, the service life of a Bosch eBike battery can be lengthened. Here, 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: Carefully clean the plug poles occasionally and grease them lightly.

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 insert the charging plug on the charger into the charging socket in the battery mount and insert the power plug into the wall outlet. Done! The batteries should be charged at room temperature in a dry location where a smoke detector is installed.

If the battery cannot be charged directly on the eBike, the PowerPack and PowerTube can also be easily removed.

Removal and installation

The Bosch batteries are seated securely in their mounts, even when travelling over rough terrain. However, they are easily removed for storage or charging purposes: Simply open the lock, which serves as an attachment and remove the battery from the mount.

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

Care

The Bosch battery is an important component of the eBike. With the correct handling and care its service life can be lengthened.

Cleaning & care

A damp cloth is recommended for cleaning the battery. The plug poles should be cleaned occasionally and lightly greased. The battery should first be removed before cleaning the eBike. To protect the electronic components, the batteries must never be cleaned with a direct jet of water or high pressure hose.

Storage during winter

Store the batteries in a dry location at room temperature. Fully charging or fully discharging results in higher loading of the battery. The ideal charge status for lengthy periods of storage is
approx. 30% to 60% or two to three LEDs on the battery indicator.

Winter use

During winter use (particularly below 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 cold conditions, it is advisable to use thermal protective covers.

Transporting your eBike

Lithium-ion batteries store large amounts of energy. That's why some precautions are necessary during transport. Ideally, the battery should be set to approx. 30% discharged and only fully charged again at the destination.

By car

If the eBike is being transported with a bike rack, remove the battery first and place it in a safe location inside the car.

Flights

Air transportation organization IATA has forbidden the transportation of eBike batteries on passenger planes. We recommend renting a Bosch eBike battery at your destination. You should check in advance whether the airline will transport eBikes without a battery.

By train

In trains with bicycle compartments, there is usually no issue with carrying eBikes (up to 20 mph). You often need to get an extra bike ticket and make a reservation for the eBike. The eBike battery must remain permanently installed during the journey and must not be charged. Before starting your journey, you should contact the respective service provider for precise information on the transport conditions. It is not always possible to take eBikes on all routes.

On commuter services and long-distance buses

On commuter services, for example on light rail services, it is often permissible to take a bike on board at regional off-peak times, provided you have purchased a bicycle ticket. It is advisable to obtain information from the relevant transport authority before travelling. The policies for transporting eBikes on long-distance buses vary between companies. Therefore you should enquire in advance of 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 rent one at your destination.

Service life

The service life of Bosch batteries is influenced mainly by the type and duration of use. Like every lithium-ion battery, a Bosch battery also ages over time, even if you do not use it. Over time it loses capacity.

Factors that shorten the service life:

  • Heavy-load use

  • Storage at over 86 °F ambient temperature

  •  Prolonged storage in a completely charged or completely discharged state

  •  Parking of the eBike in the blazing sun

  • Regular complete "discharge" of the battery

Factors that extend the service life:

  • Low-load use

  • Storage at moderate temperatures – ideally at room temperature

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

  • Parking the eBike in the shade or a cool location

 

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 by other means of transport 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 properly recycled.
