Carrying a Phone on the Bike: Clear Panel, Small Bag or Mount

The phone has become the one thing on a ride that is never in the right place. It is the map, the camera, the payment card and the thing that buzzes; it is checked at every junction and at every climb; and it lives in a jersey pocket, where it is unreachable, or in a jacket, where it gets rained on, or in a bar mount, where it gets rained on and shaken and also seen by everyone at the café.

There are two ways to carry a phone on a bike, and they suit different rides. A bag with a clear panel — on the frame, just behind the head tube, or on the handlebar — lets you see the screen while riding and keeps the phone out of the weather, and it is the better choice for navigating a route you do not know, for rain, and for anyone who does not want the phone on show. A small bag without a window — a top tube bag, a stem bag, a hip pack — keeps the phone one zip away, which is enough when you only look at it when you stop. A bar mount is the third option, and it is right for a ride where the screen is on all the time and the weather is dry.

Here is how each way behaves, what to check before you order, and which of our bags do which.

Seeing the screen: bags with a clear panel

The reason to want a window is navigation. Following a track on a route you do not know means looking at the screen every few minutes, and stopping to unzip a bag every few minutes turns a ride into a series of stops. A clear panel puts the map where you can glance at it and keeps the phone under fabric the rest of the time.

Two of our bags are built around the panel. SENSOR is a compact frame bag, eighteen centimetres long, with a removable transparent phone compartment on the side that faces you: the phone is visible while you ride, and the compartment lifts out when you would rather carry the bag without it. It mounts at three points in the front of the frame triangle, opens with a zip, and holds keys, cards and a tool as well. ATLAS is the handlebar version — a compact bag, twenty-six by sixteen by nine centimetres, with a clear front pocket over the main compartment; the city version of ATLAS has a transparent zip pocket on the face and comes off the bar as a small shoulder bag. Both are in the handlebar bag range; SENSOR is with the frame bags.

Two things to know about windows. Most touchscreens respond through a thin clear panel, but they respond worse with wet gloves and not at all with thick ones, so the panel is for looking rather than for typing — plan the route before you leave. And a phone behind a panel in full sun gets hot; on a summer afternoon it is worth moving it into the shade of the bag for a while, which is one reason SENSOR's compartment is removable rather than sewn in.

The angle decides which bag

A frame bag window faces sideways and slightly up, so you look down and left, or down and right, at the map. A handlebar bag window faces up and back at you, in the same line as the bike computer, and it is the easier of the two to read at speed. A handlebar bag also carries the phone in front of the steering axis, which is fine for a phone and a jacket but not for much else. On a bike with drop bars and a narrow front, the frame bag keeps the cockpit clear; on flat bars with room, the handlebar bag reads better. If the phone is the map for the whole ride, the handlebar wins; if it is the map for the last two kilometres, either does.

Reaching it at a stop: bags without a window

Most rides do not need the screen visible. You need the phone in a place you can open with one hand at a junction, and put back without thinking, and that is a job for a small bag near the front of the bike.

The top tube bag is the usual answer — behind the stem, opened forty times a ride, the fastest bag on the bike to get into. What to look for in one is in top tube bags. A stem bag or feeder — Feeder Clips is sixteen by ten centimetres with a buckled flap and an outside pocket — takes a phone beside the stem in the same place it takes a bottle, and the FEEDER family has several sizes; the case for one is made in bike stem bags and feeders. A compact frame bag in the front corner of the triangle — MINIM, L-6, BRAUNI — holds the phone with the keys and a tool. And for the rider who wants the phone on them rather than on the bike, a hip pack keeps it at the waist and comes into the shop with you, which is the argument in cycling hip packs.

Bag or mount?

A bar mount holds the phone in the open where it is easiest to read and easiest to tap. It also holds it in the rain, in the sun, in the vibration of a gravel road, and in view of anyone standing near the bike at a stop. Camera lenses do not enjoy a long day of bar vibration, and a phone that cooks in a mount on a July climb will turn itself off at the top.

The bag is the answer for weather, for heat, for gravel and for the café stop. The mount is the answer for a ride where the screen is on the whole time — a race, an unfamiliar city, a day of turn-by-turn — and the weather is kind. Many riders own both: the mount for the days it earns its place, the bag for the rest. A bag with a window is the compromise that covers most days on its own.

Rain, and the battery

No zip is a seal. A phone in any bag with a zip lid is water-resistant rather than waterproof, and in serious rain it wants a small dry bag or a resealable freezer bag inside — the same advice as for any electronics, and the reasoning is in waterproof vs water-resistant bike bags. Behind a clear panel it is better protected than in an open mount, because the panel and the fabric take the direct spray, but it is not sealed there either.

Navigation empties a battery, and a phone that runs the map all day wants a power bank. The pairing that works is a power bank in the bag under the phone with a short cable between them: a frame bag or top tube bag takes both, the cable stays inside, and nothing dangles. Keep the cable short and the bank low in the bag so it does not press on the screen.

What goes with the phone

The phone bag is also the wallet. Cards, a note or two, the house key and a small light are the things that travel with it, and they belong in the same bag so that one bag comes off the bike at the shop. An inner pocket for the cards and a clip for the key stop them migrating to the bottom. If the bag is a top tube or feeder, it has room for exactly this; if it is a hip pack, it has room for this and a jacket.

If you want one for your phone

Tell us the phone — the model or its dimensions with the case on — and whether you want to see the screen while riding or only reach it at a stop. SENSOR's phone compartment and ATLAS's clear pocket are sized to common phones; if yours is large, say so and we check the fit before making the bag. Write to help@lesenok.shop.

In short

• Want to see the screen while riding: a bag with a clear panel — SENSOR on the frame, ATLAS on the handlebar.
• Only need it at stops: a top tube bag, a feeder or a small frame bag, one zip away.
• Want it on you, not on the bike: a hip pack.
• A bar mount is best for reading and tapping, worst for rain, sun and gravel.
• Touchscreens work through a panel for glancing, not for typing; plan the route first.
• A dry bag inside for real rain; a power bank in the same bag for a day of navigation.

Questions we get asked

Can I use the touchscreen through the clear panel?

For a tap or a swipe with a bare finger, usually yes. For typing, or with wet or thick gloves, no. Treat the panel as a window for reading the map and do the typing at a stop.

Which phone sizes fit SENSOR and ATLAS?

Both are sized for common phones with a case on. If yours is one of the large models, send the dimensions and we confirm before making it, and SENSOR's compartment can be adjusted at the making stage.

Does the phone get hot behind a window?

In direct summer sun, yes — the same as in a bar mount. If the ride is long and hot, move the phone into the body of the bag for the climb and back to the window when you need the map. SENSOR's compartment lifts out, which makes that a five-second change.

Is a frame bag or a handlebar bag better for navigation?

The handlebar bag is easier to read at speed because the screen faces you. The frame bag keeps the cockpit clear and the phone lower and more protected. On drop bars with a crowded front, the frame bag; on flat bars with room, the handlebar bag.

Where should the phone go on a gravel ride?

In a bag rather than a mount — vibration and dust are the two things a mounted phone dislikes most. A frame bag window or a top tube bag behind the stem both work; the top tube bag is the faster to reach, the frame bag the calmer ride for the phone.
