VM Test Blubrake: This is how the E-Cargobike rides with ABS
Recently, the Italian start-up company Blubrake introduced an anti-lock braking system (ABS) for e-cargo bikes for the first time, significantly increasing the safety of these trendy modes of transportation. We were allowed to take an initial test ride, both unloaded and loaded with three six-pack beverage crates weighing about 50kg. And lo and behold: We've never come to a stop so safely and quickly on a gravel road with a bike. Normally, we would have skidded straight ahead mercilessly with the long basket in front of us; the more weight, the longer and more helpless the slide. And with ABS? All you notice is a dry jerk from the system, which is seamlessly integrated into the hydraulic braking system of the Long John e-bike. Interestingly, it performs even more smoothly when loaded than with an empty front box. It should be noted that, for cost reasons, the test bike was plausibly only equipped with the anti-lock aid on the critical front wheel.
Driving behavior stabilized
Pleasingly, even panic braking loses its terror, because you don't lose control or provoke a locking brake even with a rough grip on the brake levers. This is particularly useful when a vehicle emerges from a driveway or a parking spot. In the past, you would have had to rely on the famous stutter brake. Especially in commercial applications or when "Mom/Dad Taxi" is out with children and groceries, this impressive system should prove its worth quickly. It definitely contributes to the stabilization of driving behavior, while the Douze bike used as the basis for the test is one of the easiest-to-ride representatives of its kind. Incidentally, the brake remains functional even if the ABS, which can be activated by a button, is switched off.
Overdue Feature in the Context of Electrification
From the perspective of Sales & Marketing Manager Herwig Reus, ABS for e-bikes and e-cargo bikes is a long-overdue feature, considering how long it has been standard in cars and now also common in motorcycles, although only mandatory for heavy machines. He sees the new safety feature as a sign of the professionalization of bicycle technology. However, the electronics are already so complex that a retrofit makes little sense from his point of view. They are in talks with several high-end bike OEMs for original equipment. After all, safety is playing an increasingly important role due to the e-bike boom. Such a tech feature can clearly differentiate them from the competition. The ABS is suitable for all types of e-cargo bikes and can be combined as an open system with all standard hydraulic brakes and drive systems from other suppliers. A patented AI system is also expected to prepare the system for different surfaces, such as gravel, cobblestones, leaves, or in rain and snow.
Treacherous Front Wheel Locking is a Thing of the Past
In the system developed by engineer Fabio Todeschini, a sensor measures the speed of the front wheel and transmits the information to a control unit. This unit calculates the bike’s dynamics based on the results from the speed sensor and accelerometers in the frame and is designed to identify potentially dangerous situations. In such hazardous situations, the actuator engages and controls the hydraulic pressure of the front wheel brake, which in turn ensures a smooth braking process and increased stability and maneuverability of the e-cargo bike. According to statistics, 58 percent of e-bike accidents occur during braking, and 24 percent are related to it. 39 percent of falls occur because the front wheel is locked, and 25 percent because the rider loses balance, the Italian bike innovator explains.
