Over 60% of Strava sessions are tracked on smartphones rather than dedicated bike computers. If you're one of the millions of UK cyclists who relies on your phone for navigation, ride tracking, or just keeping an eye on the time, you need a decent bike phone mount. The question is: which type?
From simple silicone straps to premium case-based systems costing upwards of £50, there's a huge range on the market. This guide breaks down every type of bike phone mount available in the UK, what actually matters when choosing one, and which options offer the best value for different riding styles.
Stuffing your phone in a jersey pocket works, but it's far from ideal. You can't glance at your route without stopping. You can't see incoming calls. And every time you fish it out mid-ride, you risk dropping it on tarmac.
A handlebar phone mount keeps your screen visible and your hands on the bars. That's a safety advantage, especially on unfamiliar roads or busy commutes. It also means Strava and Komoot can run with the screen on, giving you turn-by-turn directions without earbuds.
If you'd rather keep your phone protected inside a bag, we've covered that separately in our guide to carrying your phone safely while cycling. But if you want your screen visible and accessible, a mount is the way to go.
There are four main types on the market right now. Each has genuine trade-offs, so the right choice depends on how you ride.
These use flexible silicone bands or a one-piece silicone cradle to grip your phone directly. No special case required. You stretch the silicone over the corners of your phone, and it holds firm through road vibrations and potholes.
Price range: £10 to £20
Weight: typically 40g to 60g
Best for: commuters, casual riders, and anyone who doesn't want to buy a proprietary phone case
The BTR Silicone Handlebar Phone Mount is a good example. It weighs just 54g, fits virtually every phone on the market (with or without a case), and attaches to any handlebar shape, including carbon bars. There are no moving parts to rust or seize up, and the one-piece design means nothing rattles loose over time.
The main limitation of silicone mounts is that they don't offer weather protection. Your phone is fully exposed to rain. For dry rides and fair-weather commutes, that's not an issue. For year-round UK riding in all weathers, you might want a waterproof phone bag as a backup for the worst days.
These use adjustable arms or jaws that clamp around the edges of your phone. Popular brands include Lamicall, GUB, and Nite Ize. They tend to feel more secure than basic silicone straps and often include a locking mechanism.
Price range: £12 to £30
Weight: 80g to 150g
Best for: riders who want a locked-in feel without committing to a specific phone case
The downside is bulk. Clamp mounts are heavier and can block parts of your screen, particularly the corners. Cheaper models are also prone to vibration rattle on rough surfaces, which gets annoying fast. Check reviews carefully before buying, as quality varies enormously in this category.
These are the premium option. You buy a specific phone case with a built-in mount interface, plus a handlebar mount that clicks or twists into place. Quad Lock and SP Connect are the two biggest names. Peak Design also offers a magnetic system with a universal adapter.
Price range: £40 to £80 for the full bundle (case plus mount)
Weight: 100g to 180g (combined)
Best for: road cyclists, long-distance tourers, and riders who want one-handed attach and detach
The attachment is rock-solid and one-handed. Vibration dampening is excellent on the higher-end models. Many also offer optional weatherproof covers and out-front mounts for a clean, aero look.
The catch: you're locked into an ecosystem. Quad Lock cases only work with Quad Lock mounts. If you change phone, you need a new case. And the total cost adds up quickly, especially if you want mounts on multiple bikes.
Magnetic systems like Peak Design and Rokform use strong magnets to hold your phone in place. They're the sleekest option and offer genuinely quick one-handed mounting.
Price range: £50 to £100+
Best for: riders who prioritise aesthetics and convenience, and are happy to pay for it
For most UK cyclists, magnetic mounts are overkill. They're expensive, and the magnetic hold, while strong, doesn't inspire the same confidence as a physical lock on rough terrain. If you're riding smooth tarmac and want the cleanest setup, they're lovely. For anything else, a twist-lock or silicone mount does the job for a fraction of the cost.
Phone sizes vary wildly. An iPhone SE is 138mm tall; a Samsung Galaxy S24 Ultra is 162mm. If you upgrade your phone every couple of years, you don't want a mount that only fits one size. Silicone mounts and adjustable clamps handle this well. Case-based systems require you to buy a new case every time.
Most mounts fit standard round handlebars (22mm to 32mm diameter). But if you have aero bars, oversized bars, or a non-standard stem, check compatibility before buying. The BTR silicone mount's flexible strap design means it wraps around virtually any bar shape without issue.
This is a bigger deal than most people realise. Sustained vibration can affect your phone's camera stabilisation over time. Apple even published a support article warning about it. Silicone naturally absorbs high-frequency vibration. A German cycling research institute found that silicone-based mounts reduce vibration in the 80 to 200 Hz range by up to 63% compared to rigid metal clamps. That's a meaningful difference on UK roads, which aren't exactly billiard-smooth.
Matters more on road bikes than commuters. A 54g silicone mount is barely noticeable. A 180g case-based system with an out-front arm adds up, especially if you're already carrying a phone, lights, and a bell.
Can you still swipe the screen and tap the corners with the mount attached? Some clamp mounts block the edges. Silicone mounts leave the screen mostly clear, though the corner bands do sit over the very edges. If you need full-screen access for touchscreen navigation, check that the mount doesn't interfere with your phone's gesture zones.
| Mount Type | Price | Weight | Universal Fit? | Weatherproof? |
|---|---|---|---|---|
| Silicone (e.g. BTR) | £10–£20 | 40–60g | Yes | No |
| Clamp/Cradle | £12–£30 | 80–150g | Yes | No |
| Case-based (Quad Lock) | £40–£80 | 100–180g | No (specific case) | Optional add-on |
| Magnetic | £50–£100+ | 80–130g | With adapter | No |
For most UK cyclists, a silicone universal mount is the smartest starting point. It works with any phone, fits any bike, costs under £20, and absorbs vibration better than rigid alternatives. You're not locked into buying matching cases every time you upgrade.
Our BTR Silicone Handlebar Phone Mount has been tested across iPhones, Samsungs, Pixels, and plenty more. It weighs 54g, installs in seconds without tools, and works in both portrait and landscape orientation. For commuting, weekend rides, and Strava tracking, it does everything you need without the £50+ price tag of a case-based system.
If you ride long distances in heavy rain regularly, consider pairing a mount with a waterproof phone bag for the worst weather days. A silicone mount handles light drizzle fine (your phone's own IP rating does the work), but for prolonged downpours, a bag gives extra peace of mind.
Case-based systems like Quad Lock make sense if you ride competitively, want an out-front mount position, or simply prefer the premium feel of a dedicated system. Just budget for the full ecosystem cost: £40 to £80 upfront, plus a new case every time you change phone.
Silicone mounts won't scratch or damage any handlebar material, including carbon. Clamp-style mounts can mark bars if overtightened, so use a torque wrench on carbon and always place a rubber shim between the clamp and the bar.
Silicone and clamp mounts work with most cases. Very bulky rugged cases (like OtterBox Defender) can be too thick for some clamps. The BTR silicone mount stretches to accommodate cases up to about 10mm thick, which covers the vast majority.
There's currently no specific law banning phone use while cycling in the UK, unlike the law for drivers. However, you can still be charged with "cycling without due care and attention" if phone use causes dangerous riding. Using your phone in a mount for navigation is perfectly fine. Just don't try to text while riding.
Apple warns that prolonged exposure to high-amplitude vibration (think motorbikes, not bicycles) can affect the optical image stabilisation system. Normal road cycling vibration is unlikely to cause issues, especially with a silicone mount that dampens the worst frequencies. If you're worried, avoid mounting your phone on rough off-road terrain for hours at a time.
