​Whether it’s navigating unfamiliar routes or checking performance data, smartphones are taking on more and more tasks when cycling. A mount that holds the device securely in place is therefore essential. We tested six solutions with different designs and price points to compare them.

Article topics and an initial conclusion

Anyone who uses their smartphone for navigation or as a fitness tracker expects a handlebar mount to provide, above all, a secure hold and straightforward operation. The Fidlock Vacuum takes a different approach to this than its competitors in the test: rather than relying solely on a mechanical locking mechanism, the system combines magnetic force and vacuum technology. This promises ease of use and high compatibility with a wide variety of smartphones.

In practice, the Fidlock proved to be one of the most convenient solutions in the test. The smartphone is attached to the mount via an adhesive pad and, thanks to the magnetic guidance, almost automatically slots into the correct position. The vacuum system then ensures a secure hold. To remove it, you simply need to press the retaining ring downwards, which requires a bit of finesse only if you’re wearing long gloves. Another plus point: unlike with some clamp-style mounts, the side control buttons remain fully accessible.

Weighing just 51 grams, the Fidlock is also the lightest mount in the comparison and is therefore particularly appealing to riders who are conscious of weight. In our test, the connection proved to be slightly less torsionally rigid than the systems from Quad Lock or SP Connect, which rely on a mechanical locking mechanism. However, this impression is based on our test setup using a universal pad. For an additional charge, Fidlock also offers custom-fit smartphone cases that protect the device in everyday use and further optimise the connection to the mount. Due to its low weight, the editorial team also awarded it a ‘recommended buy’ rating.

Here is our test conclusion

​The Fidlock mount Weighs just 50 grams, is very compact and is barely noticeable on the handlebars, which is why it’s our top pick. The universal adhesive pad fits any smartphone, is barely noticeable and doesn’t get in the way even during everyday use of the phone. Installation is straightforward thanks to the two brackets supplied for different handlebar diameters; alternatively, the mount can also be attached to aero handlebars using cable ties. The handling is impressive thanks to the vacuum-magnet technology: the smartphone docks magnetically; to release it, simply press the locking ring. All the buttons on the phone remain accessible. On bumpy sections, the smartphone wobbles slightly.
