Bike Phone Holder B1 with Anti-Shock & Vibration Reduction, Black

Inside the base there are four independent sets of springs arranged in a square around the central axis. This layout absorbs vertical impacts from potholes and cobblestones as well as horizontal oscillation from the motor or the wheels of an e-bike, so less shaking reaches the phone and its camera. Holders with a single spring element mainly damp vertical impacts, while a set of four springs also handles the chaotic vibration that arrives from all directions at once while riding. It shows most on the optical stabilisation of the camera: phone manufacturers warn that long-term strong vibration damages it, and on handlebars it is the most exposed of all.

The gripping surfaces inside the clamp are covered with vulcanised silicone padding 10 mm thick. The silicone has two jobs here: in each of the four corners it works as a micro-damper for the small impacts that get through the springs in the base, and at the same time it stops the phone from shifting during a sharp change of direction or braking. The phone therefore does not rest on hard plastic but on a material that gives way slightly under pressure and springs back. The soft surface will not scratch the back of the phone or its case, so the holder also handles a phone without a case.

The lock and the clamp are among the most stressed parts of the holder, because they are used on every ride. The supplier's internal testing on the YYS-683 model included a lock test over 10,000 open and close cycles and an insertion test over 3,000 insertions and removals of a phone, in both cases with the mechanism staying smooth. A temperature test and a bump test simulating vibration at high riding speed were carried out in addition. The figures given describe the scope of the tests performed, not a guaranteed service life.

The holder weighs 164 g, so it has practically no effect on handling the bike even with a phone in the clamp. Folded it measures 96.3 x 141.6 x 32.5 mm, and with the clamp opened to the maximum phone size 96.3 x 191 x 32.5 mm. On bikes with a handlebar bag or with the front light mounted on top you need to take this height into account. On the cockpit it takes up one spot and leaves room next to it for a cycling computer or an e-bike display.
