A bike phone mount keeps your phone in clear view for navigation, ride-tracking and music while both hands stay where they belong — on the bars. The best hold your phone rock-steady over potholes, kerbs and rough trails, because a phone that shakes loose at speed is an expensive disaster. An extensive test of bike phone mounts sorted the best, and these are the top picks, checked against current UK prices.
What to Look For
Case-based or universal. This is the key split. The most secure systems, like Quad Lock and SP Connect, use a dedicated phone case (or an adaptor) that clips or twists positively onto the mount — utterly solid, but you commit to their case. Universal mounts instead grip any phone with a clamp or ring and need no special case. Beware cheap stick-on adaptors: their adhesive often will not bond to silicone, TPU or leather cases, which rules out most covers.
Locking and security. The mechanism is what stops a costly drop. Quad Lock's quarter-turn twist-lock and the various clamp and ring designs all aim to hold firm through vibration and impacts. Look for a positive, two-stage lock you can feel engage, and test it hard before you trust it with your phone on a bumpy descent.
Fitting your bike. Most mounts clamp to standard 31.8 mm handlebars, with smaller shims for narrower bars, and you can usually choose a stem-top or an "out-front" position that sits ahead of the bars for a clearer view. Check the mount suits where you want the phone and the diameter of your bars.
Phone size and protection. Make sure the mount takes your handset — the best handle large phones up to around 6.8 inches, or roughly 85 mm wide and 14.5 mm thick. On rougher rides, remember that sustained handlebar vibration can, over time, affect a phone's camera, so a mount with some damping is worth having for off-road use.
Weather and ease of use. A good mount shrugs off rain and lets you dock and undock the phone one-handed in seconds. And as ever, set it up for a quick glance at your route — never for tapping away while you ride.
The Winner: Quad Lock Bike Kit
The Quad Lock Bike Kit (around £49.98) is the best bike phone mount for most cyclists, and a genuine favourite of the cycling community. It works on a dedicated Quad Lock phone case that clips onto a mount fixed to your stem or handlebars; to lock the phone you simply push it on and give it a quarter-turn twist, and it is utterly secure. The kit includes a universal adaptor if you would rather not buy the case, and the system is beautifully engineered and endlessly expandable to your car, motorbike and desk. For a rock-solid, do-everything mount, it leads the field. Check the price on Amazon
Best Value: SP Connect

The SP Connect (around £34.47) works on the same clever principle as the winner, with a choice that keeps costs down. You can invest in a dedicated case for your exact phone for the most secure fit, or pick one of the universal modules — including one that simply sticks to the back of your existing case. It is reliable, well made and endlessly customisable across bike, car and more, and it undercuts the Quad Lock while giving away very little. For most riders it is the smart-value pick.

Best Universal: Loop Mount
The Loop Mount (around £74.23) is the choice if you refuse to buy a special case. This British brand set out to make a mount that is both discreet and utterly secure, and it succeeds: it looks like a simple band fixed to your handlebars, and the band springs open in the middle to grip any phone directly — no case, no adaptor, nothing to remember. It is the priciest here and the most minimalist, but for a universal, elegant hold that works with whatever phone you own, it is a lovely thing. Check the price on Amazon

A couple of others came up in the source test. The Decathlon Triban mount is a simple, effective and very cheap universal holder if you have a Decathlon nearby, while budget brands such as Haslaky offer basic clamp mounts for very little. Worth a separate mention is the Beeline Velo 2, which is not a phone mount at all but a tiny handlebar navigation device — a neat alternative if you would rather leave your phone in your pocket.
How to Choose
Decide how committed you are. For the most secure, expandable system and you do not mind a dedicated case, the Quad Lock Bike Kit is the one to buy. If you want almost all of that for less, the SP Connect is the value champion with a case or a stick-on option. And if you insist on using any phone with no special case, the discreet Loop Mount is made for you. Whichever you choose, check it fits your handlebars and phone, test the lock hard before your first proper ride, and use it only for glancing at your route.
Verdict
The Quad Lock Bike Kit is the bike phone mount to buy for most cyclists at around £49.98: supremely secure, superbly engineered and expandable across your whole life. The SP Connect (around £34.47) delivers the same idea for less, while the British Loop Mount (around £74.23) grips any phone with no case at all. Get your phone mounted safely and enjoy the ride with both hands on the bars.
