Frequently Asked Questions - BRIXXI Busch + Müller

How to turn the BRIXXI rear light on and off?

Press and hold the switch 3 to turn the light on or off. A short press switches between Senso and Permanent modes.

How does Senso mode work?

In Senso mode, the rear light turns on automatically when ambient brightness decreases (e.g., tunnel, dusk). In bright light, it turns off after about 5 minutes. Brake and emergency brake functions remain active. Mode indicator 4 is permanently yellow.

What to do if the rear light does not fit properly in the mount?

This may be due to a stretched or displaced protective cap 1. To correct: unscrew the screw at the back (TX8), remove the counterpart 9, adjust the soft material, reinsert the counterpart and tighten the screw. See the manual for details.

How to charge the BRIXXI battery?

Open the protective cap 1, plug the supplied USB-C cable into a standard USB charger (max. 1000 mA, 5 V) or a computer port. Charging takes about 1.5 hours. The charge indicator LEDs 5 turn off when the battery is fully charged. Do not expose to water during charging.

How long does the rear light battery last?

With a fully charged battery, the battery life is approximately 24 hours, depending on riding style, temperature, and traffic.

How to interpret the charge indicator LEDs?

5 blue LEDs = 100-80%, 4 = 80-60%, 3 = 60-40%, 2 = 40-20%, 1 = 20-10%, 1 blue + 1 orange = 10-5%, 1 orange = <5% (Safe-Way-Home mode). Below 10%, braking functions are disabled.

Is the BRIXXI rear light compatible with a 45 km/h e-bike?

No, the BRIXXI is certified only for e-bikes with assistance up to 25 km/h. Do not use on 45 km/h e-bikes.

How does the light detect braking or emergency braking?

Thanks to an integrated deceleration sensor (BREX technology). When braking, the light becomes 5 times brighter. In case of sudden braking, it switches to pulsating light mode (emergency brake light). No wiring to the brake lever is required.

Can the BRIXXI be mounted on the fork or seat stay?

No, the light must be mounted exclusively on the seat post using the provided mount. Mounting elsewhere may cause it to detach and lead to an accident.

What to do if the rear light gets wet or exposed to rain?

Remove the rear light from its mount to prevent water ingress. It is splash-proof during normal use, but should not be immersed. After heavy rain, dry it before reusing.

BREX-TECHNOLOGY - Sensor brake and emergency brake light function according to StVZO

Running light (normal operation), braking or emergency braking. Thanks to the integrated deceleration sensor, and unlike previous brake tail lights, no wiring to the brake lever is required.

Three abstract geometric diagrams with radiating lines and concentric circles, no text or symbols present.

In normal use, the rear lights with BREX technology offer cyclists the best visibility from behind. The integrated sensor system is active at all times and reacts as soon as braking or emergency braking.

BRAKING

When the braking process is detected by the integrated sensor system, the rear light illuminates very brightly and clearly to signal following road users to slow down. This is more than five times as bright as in normal operation and thus many times brighter than previous tail lights with so-called deceleration light.

EMERGENCY BRAKING

In the event of abrupt braking, the brake light switches up another level to the brightly pulsating emergency brake light function. In this mode, BREX conveys the dangerous situation with an unprecedented signalling effect and prevents accidents.

6. Assembly

Assemble the bracket and tension band to the seat-post (25-32mm diameter) so that it will not move out of position. Tension band 6 should be wrapped around the Seatpost and stretched over the bracket hooks. Then press the rear light into the twist-lock bracket 8, so that this fixes with an audible click. When removing the rear light from the bracket, turn the twist-lock rotator slightly counter-clockwise. To Protect the twist-lock bracket 8 from dirt when unused, please use the protection cap 7. Just push the protective cover 1 into the twist-lock fixation point.

NOTE If the rear light does not attach in the 8 twist lock bracket, or remains loose, this may result from an over-stretched or displaced rear light protection cap.

This can be corrected in a few simple steps:

1. loosen screw at back of the rear light. (TX 8)

2. loosen 9 counter-part bracket

3. Adjust the soft material part to fit back into the intended seating position

4. Press 9 counter-part bracket back on to the rear light

5. Re-tighten screw so that it remains in place

■ Position the rear light so that the light emitting surface is perpendicular to the roadway (see image on page 26). This is imperative for the correct operation of the light. The light is only intended for assembly on the seat post.

WARNING Never assemble on the fork or the seat stay!

To prevent falls, accidents and serious injury, use only the intended mounting bracket from Busch and Müller. If unsuitable or ill-placed brackets are used for the assembly of lights, these can lead to loosened or detaching parts that may trap in wheels or spokes and cause serious injury.

Please always check the secure assembly of your rear light mounting before riding.

Upside down assembly Incorrect: any assembly of the rear light in an inverted upside-down position is incorrect and the light will not function correctly.

18° Road surface

If the rear light is mounted upside-down, the charge indicator LED's will flash repeatedly once the light is turned on. Only assemble as pictured.

Important: Lighting equipment must not be covered at any time.

7. Charging

The rear light has a 350mAh cache battery that can be charged via the 2 USB-C charging port. The 2 USB-C port is located on the upper end of the light under the 1 light protection cap. To charge, use the USB cable with a standard USB charger block (max 1000mAh, 5V DC) or a computer USB port. During charging, the 5 charge level indicator will alight, showing the charge level of the cache battery. The 5 charge level indicator LED's will switch off when the charging process is finished.

WARNING As a measure of precaution, do not leave the rear light unattended while charging, and always place on a fire resistant surface.

NOTE During charging there is no splash or rain water resistance. Damage resulting from water or humidity entering the light while charging is specifically excluded from warranty.

1 Replace the 1 light protection cap after the charging process is completed to close the 2 USB-C charging port. The rear light cannot attach to the 9 counter-part bracket while the 1 light protection cap is open.

NOTE Open the 1 light protection cap only sufficiently to allow access to the 2 USB-C charging port. Overstretching the 1 light protection cap can lead to a displacement under the 9 counter-part bracket. To correct this, refer to point 6. Assembly.

7.1. Charge level indication

5 blue LEDs = 100 · 80 % | 4 blue LEDs = 80 · 60 % | 3 blue LEDs = 60 · 40 % |

2 blue LEDs = 40 - 20 % | 1 blue LED = 20 - 10 % | 1 blue & 1 orange LED = 10 - 5 % |

1 orange LED = < 5 %

The 5 charge level indicator will be activated by switching, or when the rear light is switched off, then by a short press of the "on" button. When the rear light needs charging (under charge level 10%, or when the rear light is in "safe way home" mode) the 5 charge level indicator LED's will remain on continuously.

Once the orange LED allights together with the blue LED, then the charge level is under 10% and the Brake function and emergency brake function will be de-activated. Please re-charge immediately.

Should the charge level sink below 5%, only the orange LED will alight, and the rear light will automatically go into "safe way home" mode.

7.2. Charging times

Charging with a standard USB charger block or a computer USB port takes appr. 1.5 hrs. While charging, the 5 charge level indicator will alight, showing the current charge level. Once the charging process is finished, the indicator LED's will go out, with a fully charged battery, the run-time is appr. 24 hrs. This will depend on ride style, temperature and traffic situation.

8. Operation / Modes

The rear light is switched on and off with a long press of the 3 switch. A short press of the 3 switch will toggle between senso-and-permanent modes.

Senso-Mode

The 4 mode Indicator LED on the right side of the rear light is continuously yellow. With fading ambient light, the rear light will automatically switch on (e.g. dark tunnel or dusk). With bright ambient light (e.g. Daytime - Sun), the standard ride light will switch off after appr. 5 mins. Brake and emergency brake functions remain active.

Permanent Mode

The 4 mode indicator LED on the right side of the rear light is not alight. Standard ride light remains on continuously. Brake and emergency brake functions are active.

Safe-Way-Home-Mode

The rear light will remain alight for at least 30 minutes with reduced brightness. Brake-and-emergency-

brake functions will be deactivated, as will the senso-mode also. The rear light is now continuously on.

The 5 charge level indicator will show only the orange LED (refer to 7.1 Charge level indication)

Standby-Mode

In order to extend battery run-time and alleviate the user of on / off switching, the rear light will switch itself off into standby mode when it recognises an extended period of inactivity (motionless). When motion recommences, the rear light will automatically then switch back on again into the previously selected mode. Once the standby mode is finished, the light must be reactivated by pressing the 3 switch. An active standby mode is shown through regular flashes of the 4 mode

9. Further Comment

Should the bicycle be sprayed with water, left out in rain or transported on a vehicle in rain, then the rear light should be removed. This is to prevent loss and / or water ingress.

Disposal: Electronic rear lights are not household waste. They are to be disposed of at the intended collection depots.

10. Liability

Damage caused by improper use (e.g. dropped, crash, unsecure assembly and consequences, immersion in water or other liquid) is explicitly excluded from the warranty. The warranty is invalid if the rear light has been opened.

We wish you enjoyment and satisfaction with your new rear light, and always a safe ride.
