Can I fit a child seat on my Stromer e-bike?

Stromer e-Bike: Child seat

Before fitting a child seat on your Stromer e-bike, bear in mind that children are protected better in a trailer than in a child seat on the carrier. 

Please remember that a child seat affects the road behavior of the Stromer. Ride with caution and adjust your speed and riding style to the conditions. The high center of gravity in particular makes parking the Stromer on the side stand more difficult. The Stromer could tip over with the child still in the seat. Please inquire with the responsible authorities about the legal situation regarding the carriage of children on S-Pedelecs (see also: Differences between Pedelec and S-Pedelec and legal regulations for EU and Switzerland).

Important: When fitting child seats, please note that the Stromer carrier has only been tested for a maximum load of 17 kg/22.5 kg (depending on the model). Therefore, only use child seats that can be mounted directly on the seat tube (ST2 Ø = 42 mm). Especially in the case of comfort frames with a low step-over height, there is not always sufficient space for the bracket. We therefore recommend checking whether it can be fitted before you buy.

Can I have a spare key made for my Stromer s-pedelec?

Stromer ST1 X, ST2, ST2 S: Spare key

All keys for the Stromer ST1 X, ST2 or ST2 S are provided with serial numbers and can be reordered by your Stromer dealer. You will find the key number in the Stromer OMNI app under “Service booklet”/“Camlock”. As each key is a one-off production, delivery can take some time. The key can be ordered by you or your dealer at www.camlock.com/de/ersatzschluessel

Alternatively, you can also have the whole lock mechanism replaced by your dealer.

 

Can I have warranty services carried out by any Stromer dealer, for example after a move?

Stromer ST1, ST1 X, ST2, ST2 S, ST3, ST5: Factory warranty

The factory warranty applies to all Stromer specialist dealers and is independent of where you bought your Stromer Speed Pedelec. Take advantage of our Store locator, to find a specialist dealer near you and contact them directly. For further information on the warranty period, warranty scope and exclusion of warranty, please refer to the Stromer warranty provisions

 

Can I mount a trailer on my Stromer e-bike?

Stromer e-Bike: Mounting a trailer

You can attach a trailer to your Stromer Speed Pedelec. For this you need the Trailer plate kit as a coupling. When buying a new Stromer you can buy the trailer plate kit in the Stromer Bike Configurator directly as an optional accessory. You can obtain it separately from your Stromer specialist dealer. The professional assembly is carried out by the dealer. 

Attention: The legal regulations for the use of trailers and child seats on Speed Pedelecs vary from country to country. Please inquire with the responsible authorities in your country whether driving with a trailer is permitted in your country (see also: Differences between Pedelec and S-Pedelec and legal regulations for EU and Switzerland).

Please remember that a trailer affects the handling of your Stromer e-bike. On tight bends, certain trailers have a tendency to tip over. For this reason, ride with caution and adjust your speed and riding style to the conditions. Some trailers are only approved by their manufacturers for use with bicycles or Pedelecs (pedal assistance up to 25 km/h). Please always observe the advice of the trailer manufacturer. Your Stromer specialist dealer will gladly advise you about the options.

Can I use my access data from the Stromer OMNI app for the Stromer OMNI BT app?

Stromer ST1 (OMNI Interface B): Using access data of the Stromer OMNI app for the Stromer OMNI BT app

The access data for your Stromer OMNI account is valid for both the Stromer OMNI app and the Stromer OMNI BT app. This means that you can use them in both apps.

Can I use the Stromer OMNI app for a Stromer I bought used?

Using OMNI app for used Stromer

To be able to use the Stromer OMNI app for your used Stromer, an authorized Stromer dealer must connect the bike to your Stromer OMNI account.

Please also ask the seller or previous owner of your Stromer s-pedelec to commission the transfer of the Stromer from his or her dealer. This ensures that he or she has actually sold or intends to sell the vehicle.

  1. Download the Stromer OMNI app to your smartphone (from the App Store or from the Google Play Store).
  2. Your dealer creates a Stromer OMNI account for you.
  3. Provide your dealer with the following information:
  • First and last name
  • E-mail address
  • Cell phone number
  • VIN of the purchased/sold Stromer

As soon as your dealer has registered you, use the Stromer OMNI app to create a PIN for your Stromer under “Settings”/”Change PIN”. This will automatically be sent to your bike and to your registered cell phone number. You can now make full use of your used Stromer.

Can Stromer OMNI be used free of charge?

Stromer OMNI: Free of charge

Stromer OMNI can be used free of charge. Once you have completed the activation, the OMNI module remains activated for an unlimited period of time and works worldwide. There are no data or roaming charges for use. 

If your Stromer is not switched on for 18 months, the SIM card is automatically switched to inactive. To reactivate it, please contact your dealer, who in turn will get in touch with Stromer Technical Support. Take advantage of our Store locator to find a specialist dealer near you.

 

Do I need a SIM card to use Stromer OMNI?

SIM card for Stromer OMNI

For the operation of the Stromer s-pedelec as well as for the use of Stromer OMNI, the bike communicates via the cell network. A SIM card is permanently installed in the bike for this. The SIM card cannot be removed or swapped.

Good cell network reception is essential for communication. The OMNI functions may therefore be limited to some extent inside buildings.

Stromer OMNI is available for Stromer ST1 X, ST2, ST2 S, ST3 und ST5.

Does my Stromer e-bike offer theft protection?

Stromer e-bikes: Theft protection

Stromer e-bikes offer you an effective theft protection. If you lock your Stromer e-bike, you alone are able to switch it back on. Theft mode is activated if the locked Stromer e-bike is moved or pushed for an extended period of time. The motor is blocked and the position of the Stromer bike is recorded periodically if a cell network connection exists. This makes your Stromer bike an unattractive proposition for pilferers.

E-bike registration: Is there compulsory registration for Stromer Speed Pedelecs?

Stromer ST1, ST1 X, ST2, ST2 S, ST3, ST5: Compulsory registration

Stromer Speed Pedelecs offer motor assistance up to 45 km/h (28 mph) and are therefore legally light motorcycles of class L1e with regard to Directive 2002/2004/EC (USA: Class 3). There is an obligation to register and insure vehicles of this category in most European countries. Before riding your Stromer for the first time, it is essential that you obtain information from your registration authority about the applicable national regulations for this vehicle category.

You can find further information in our Overview of the legal regulations for Pedelecs and Speed Pedelecs in Switzerland and the EU.

The fewer mechanical components allow for less maintenance as well as better shifting quality.

In the Shimano XTR Di2 the control is completely integrated into the display, which shows all important information such as charge status, gear position and shift mode. The battery of the Shimano XTR Di2 shifting system is also charged via the display. The ST2 S is equipped for this with a USB charging socket.

Please observe the following when charging the Shimano XTR Di2 battery via your Stromer:

  • Connect ST2 S charger to Stromer.
  • Switch on Stromer.
  • Connect the Shimano XTR Di2 charger to Stromer USB charging socket and connect to the Shimano XTR Di2 unit.

Depending on the shifting frequency and temperature, one charging cycle of the shifting system can be sufficient for up to 2,500 km. A full charge takes about 90 minutes.

For further information on the rear derailleur, display and switches, please refer to the user manual.

Problem:
After switching on, four zeros (“0000”) appear on the display and the first digit flashes.

Solution:
The system lock was activated when the power was turned off. To deactivate the system lock, see “Locking/unlocking system”.

Problem:
The interface cannot be switched on.

Solution:
Change the interface's battery. This must be removed from the handlebar for this. You require a Phillips head screwdriver and a button battery (CR2032) for this. You can also have this work performed by a Stromer service partner.

Problem:
The control unit switches on but the battery indicator light flashes even though the battery is charged.

How does the electronic shifting system of my Stromer ST2 S work?

Stromer ST2 S (OMNI Interface C): Function of the electronic shifting system

The Shimano XTR Di2 is the first electronic mountain bike shifting system. Instead of a mechanical connection between shift lever and rear derailleur, the shifting commands are transmitted electrically. Shimano thus allows a 100 % precise control. The fewer mechanical components allow for less maintenance as well as better shifting quality.

In the Shimano XTR Di2 the control is completely integrated into the display, which shows all important information such as charge status, gear position and shift mode. The battery of the Shimano XTR Di2 shifting system is also charged via the display.

Please observe the following when charging the Shimano XTR Di2 battery via your Stromer:

  • Connect ST2 S charger to Stromer.
  • Switch on Stromer.
  • Connect the Shimano XTR Di2 charger to Stromer USB charging socket and connect to the Shimano XTR Di2 unit.

Depending on the shifting frequency and temperature, one charging cycle of the shifting system can be sufficient for up to 2,500 km. A full charge takes about 90 minutes.

For further information on the rear derailleur, display and switches, please refer to the operating instructions.

How does the electronic shifting system of the Stromer ST5 work and how can I charge it?

Stromer ST5: Electronic shifting system Shimano XTR Di2 11-Speed 11-42

Instead of a mechanical connection between shift lever and rear derailleur, the Stromer ST5 transmits the shifting commands electrically.

How does the theft mode of my Stromer s-pedelec work?

Stromer ST1, ST1 X, ST2, ST2 S, ST3, ST5: Theft mode

Theft mode is activated if the locked Stromer e-bike is moved or pushed for an extended period of time. The theft mode works as follows:

  • The motor is blocked, making the bike virtually impossible to ride.
  • The position of the stolen vehicle is recorded if a cell network connection is available.
  • The lights flash.
  • The owner receives a text message on the cell phone number registered upon activation.

If your Stromer is stolen without the theft mode activated, you can activate it manually via the Stromer OMNI app. The Stromer can only be taken out of theft mode by using the Stromer OMNI app.

Please note that the theft mode is only effective if the battery is in the bike and has a minimum residual charge.

How is my Stromer e-bike protected against overheating?

Stromer e-Bike: Motor temperature regulation and protection against overheating

The motor temperature of your Stromer e-bike increases at a higher rate under heavy load. The load on the motor rises with:

  • Higher total weight
  • Lower individual output
  • Lower speed
  • Steady climb

If the motor reaches excessively high temperatures, this can lead to overheating and consequently to motor failure in conventional systems. The intelligent Stromer system monitors temperature development in the motor. Output is automatically reduced at high temperatures in order to prevent overheating of the e-bike motor. While this may temporarily lead to reduced assistance, it effectively prevents motor failure.

A bar displays the energy flow in the ride screen. The higher the output, the longer the bar. If the output of the e-bike motor is reduced due to the high temperature, this bar is shortened accordingly.

However, the output of the motor is primarily dependent on your own pedaling force and not on the motor temperature. A short bar does not automatically mean that the system is running at its thermal limit. In case of overheating, the assistance switches off automatically. Give the motor time to cool down and then continue riding.

Why does the total distance in the user statistics of the Stromer OMNI app differ from the one on the Stromer bike?

Total distance in user statistics and Stromer OMNI app

The statistics in the Stromer OMNI app provide a quick overview of the use of your Stromer s-pedelec. It is divided into “Bike Statistics” and “User Statistics”.

Bike statistics
Bike statistics shows the trip and total distance of your Stromer and corresponds to the display on the bike. The total distance driven is displayed, including rides of a possible previous owner.

User statistics
User statistics shows the history of your personal Stromer usage and includes all Stromer trips you have made as a registered user. So all your trips are added up, regardless of which of your Stromer bikes you have made them on. Rides that were made on your Stromer before you were registered as an owner on the vehicle are not considered. Therefore, the total distance of the Bike statistics may differ from the total distance of the User Statistics.

Note:
User statistics is automatically created from the status messages sent by the bike on a regular basis. If the bike has no cell network reception for a longer period of time although it is being ridden, there may be deviations in the distances actually covered and the distances shown per day.
