DEKRA expert opinion MAGURA IBS

DEKRA Testing and Certification GmbH has independently assessed the Integral Braking System (IBS), developed by MAGURA, in an extensive test program. In a realistic blind test with cargo bikes – both with and without IBS – the system demonstrated its strengths. The evaluation was carried out both on the test bench and in realistic road trials with seven test riders of different ages and experience levels.

The result:
IBS increases riding safety, significantly shortens braking distances, and provides greater stability, especially under heavy loads and in demanding situations.

Test bench measurements:
The measurable overall deceleration when applying the rear brake with IBS results in higher total braking force. The distribution not only enables all-wheel braking but also generates greater braking forces at the tire contact patch. Compared to manual two-hand braking, the system proves superior, particularly when a rider’s coordination of hand brake forces might otherwise risk front wheel lock-up.

Field tests with emergency braking:
Seven test riders were evaluated under real-world conditions. With a fully loaded e-cargo bike, IBS achieved an average braking deceleration of 5.8 m/s² and a braking distance of 5.9 m. Without IBS, the deceleration was 3.5 m/s² with a braking distance of 8.8 m.

Downhill tests with experienced riders:
In practical use, the cargo bike equipped with IBS showed a clear advantage in terms of operating comfort and safety. In demanding riding situations – such as downhill sections or sudden braking maneuvers – the system eliminates the need for the rider to actively balance braking force between the front and rear wheel.

All three DEKRA tests consistently confirmed that the system is intuitive to use and reliably supports both one-hand and two-hand braking. It provides measurable safety benefits, particularly for less experienced riders.
