Digital speed limiter with push-button double-check and automatic reactivation - Digital calculation and control of speed and RPM.

Function:
The DZB has a powerful microprocessor at its heart, which continuously calculates and evaluates the current speed and RPM. The speed is determined by the DZB via the supplied wheel sensor together with a small self-adhesive magnet for the rim. The RPM is calculated directly via the pickup cable of the CDI ignition with each piston stroke.
The DZB can be operated in KMH mode, RPM mode or combo mode.

KMH mode:
In KMH mode, a speed upper limit is stored in the DZB. When this limit is reached, the DZB throttles the scooter by reducing the RPM. Via a variably adjustable pre-stage, the RPM is reduced stepwise shortly before reaching the maximum speed, in order to achieve a clean transition. If the vehicle is below the set maximum speed, the RPM is not regulated. This has a positive effect on acceleration and on the speed on uphill journeys compared to regular RPM limiters. To operate the DZB in KMH mode, the supplied wheel sensor and wheel magnet must be installed on the front or rear wheel.

RPM mode:
In RPM mode, the wheel sensor is not required. Here, the DZB only throttles the scooter via the adjustable maximum RPM. When the maximum RPM is reached, the DZB regulates the engine down. At an RPM below the set limit, the DZB does not intervene. This results in no loss of performance in the lower RPM range. To make the transition to throttling a little smoother, different-sized pre-stages can also be adjusted here. In these pre-stages, the DZB already throttles every 3rd ignition pulse shortly before reaching the maximum RPM.

Combo mode:
In combo mode, the DZB works simultaneously with the set RPM and KMH limits. This is particularly useful if you want to set a relatively high-revving scooter to a low top speed. So that the scooter does not rev suspiciously high when starting up, the maximum RPM can already be reduced before reaching the top speed.

Programming and Control:
Programming the maximum speed/ maximum RPM is very simple. A simple press on the internal program button is enough to store the current speed or RPM as an upper limit, depending on the operating mode.
To deactivate the throttling, simply pull the brake briefly and operate the button at the same time. To reactivate the throttling, simply turn the ignition off and on again briefly.

Dimensions:
The housing is tiny. The dimensions are 45x45x18mm + mounting lug. The length of the connecting cables is 45-50cm, the button cable is approx. 100cm long. The dimensions of the wheel sensor are only approx. 28x19mm, the cable length is approx. 50cm.
Attention: The original cable length of the wheel sensor is quite short with 50cm, especially if the sensor is to be attached to the front wheel or near the axle hub!
You will also receive 4 quick connectors, with which the installation is child's play and super fast! No more cutting and soldering on the wiring harness!

Installation:
For the installation you need to connect the 4 cables of the DZB. You need +12V (switched via the ignition lock), brake signal, pickup signal and ground/ minus. For KMH mode, you must also install the wheel sensor and wheel magnet on the front or rear wheel of the scooter. The sensor detects the wheel revolutions, similar to a bicycle speedometer. The distance between sensor and magnet on the wheel should be approx. 5-15mm. The wheel sensor can usually be easily attached between wheel and variomatic housing, frame or fork. The magnet has a 3M adhesive layer and can be easily attached to the rim edge or in the interior of the brake disc. Although the magnet is self-adhesive, we recommend permanently fixing the magnet with a 2K adhesive once the optimal position has been found.
Inside the DZB there are two control LEDs, with which you can check the correct installation and function.
