At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Cheaper than most waterproof phone holders, the Triban 900 L Waterproof Bike Smartphone holder will keep your phone dry in a downpour. It's quick and easy to get off the bike, although the see-through plastic isn't completely clear, which can create problems for Face ID.


No hex keys needed here. The holder uses a tool-free mounting system where you tighten up the bolt by hand. It stayed nicely in place on my rides, while the soft blue padding inside the mount prevented any scratches to my handlebar.

The ability to slide your phone in and out while still in the plastic case is pretty handy too. I was expecting it to be a little fiddly, this wasn't the case. You can use one hand to press the release catch on the back of the phone and glide it off.

My only small mount-related annoyance is there's no adjustment dial. Quite a few phone holders have a small dial that sits behind your phone. This lets you adjust the angle of your screen by loosening off the dial without having to unscrew and readjust the whole mount.

Nothing exciting to say here. It's definitely waterproof! I ran it under the tap to simulate a UK monsoon-like deluge, and the paper I'd put in it stayed bone dry.

The double wrapping must help with that; the plastic of the holder rolls up like a dry bag and is secured by Velcro, though this can feel a little fiddly as there's just one small strip of Velcro that you need to line up exactly. The black flap that you see in the picture then wraps over it for added protection.


The touchscreen works as expected, with my phone being as responsive as when it's out of the case. I wasn't having to use more pressure for my clicks or be more deliberate in my actions.

Unlike the Triban 500 phone holder that I was testing at the same time, however, the see-through plastic isn't completely clear. You can see your phone screen fine, but it's ever so slightly murky, as though somebody's breathed a small amount of condensation onto it. I kept feeling like I wanted to wipe it with my sleeve. The result of this is that Face ID doesn't work. If I wanted to close off the screen to conserve battery, then re-open it, I had to pull over and put in my pin code.

The holder provides impact protection from scratches and bumps with a layer of thicker plastic inside, which hugs the back and sides of your phone. Again, this caused some difficulties when it came to locking or unlocking my phone, as I was struggling to press the unlock button on the side through the thicker plastic.

It's durable and you get the sense it will last. The seams are held together with an adhesive, which stayed in place despite me channelling my inner baboon and trying to rip them apart.


If you simply want a phone holder and are not bothered about waterproofing, then the £9.99 Triban 500 that is not only cheaper, it also has a completely clear see-through plastic screen cover. Triban also has the £14.99 cycling smartphone mount, which although we've never reviewed on here, I have on one of my bikes and have found it pretty effective.

If you're looking for something waterproof, then it would be worth also having a look at the Altura Slim Pocket Wallet that Steve reviewed last year. It seems to be out of stock in quite a few places but is still available. There's also the Zefal-Z Console that Matt liked for its simplicity and security, which cost between £17 and £22, depending on the size of your phone.


My phone was kept waterproof and protected from bumps and scrapes, but the case prevented me being able to unlock my phone quickly. The harder plastic protection meant I couldn't press the unlock button on the side of my phone easily. When I did manage it, the murky see-through plastic then prevented Face ID working.
