Bike Top Tube Bag — The Ridgeline Pilot Phone Bag
✓ Free worldwide shipping ✓ Ships in 7–14 business days ✓ 30-day money-back guarantee
If you ride to work, follow a GPS route or just hate stopping to dig your phone out of a jersey pocket, a phone-forward top tube bag is the single most useful upgrade you can bolt to a bike. The Pilot puts your screen right where your eyes already fall — just behind the stem — and wraps it in a hard shell that shrugs off rain, road grit and the odd knock.
Why put your phone on the top tube?
Commuting and navigation are where the Pilot earns its keep. Cycling has become mainstream transport again: over 50 million Americans ride a bike each year, and a growing share of them are using their phone as a route planner, fitness tracker and payment card all at once. The problem is where to put it. A jersey pocket means stopping every time you need to check a turn. A bar-clamp mount leaves your screen naked in the rain and dangling off the front of the bike. A bike top tube bag solves both: the phone is protected inside a hard shell, and the touchscreen window means you never have to open anything to see the map.
There is a handling benefit too, and it is real physics rather than marketing. A frame bag — whether it is our Trail triangle bag or the Pilot on the top tube — carries load low and centered inside the frame. That keeps the center of gravity down and the bike stable, unlike a heavy backpack that raises your weight and shifts around, or a rear rack that pushes weight behind the axle. Your phone rides where it barely affects the balance of the bike, and you feel nothing different when you corner or climb.
What makes the Pilot different
Plenty of top tube bags are soft fabric pouches with a stretchy pocket on top. The Pilot is built the other way around — as a protective case first, storage second — which is exactly what a phone-forward rider wants.
- Touchscreen window that really works. The clear top is a genuine touchscreen film, not just a see-through flap. You can tap, swipe, pinch-zoom the map and answer a call without opening the bag. One verified buyer noted the window even reads their fingerprint to unlock the phone.
- Waterproof hard shell. A rigid PU/EVA body and sealed window keep rain, road spray and grit off your phone. When the skies open mid-commute, your screen stays dry and readable — a soft pouch simply can't promise that.
- Fits phones up to 7 inches. That covers essentially every modern handset, including the biggest Pro Max and Ultra models. Slide the phone behind the window and the rest of the bag holds keys, cards, a gel or a small multitool.
- Three-strap velcro mount. Two straps on the top tube plus one on the head tube lock the bag down so it doesn't sway or twist on rough ground. The soft backing sits flush against the frame and won't scratch your paint.
- Low, aero, out of the way. Tucked behind the stem, the Pilot stays clear of your knees on the climbs and out of the wind, so it never gets in the way of a hard effort.
Our test: how the Pilot handles a wet commute
We ran the Pilot through the same real-ride checks we use on every bag before it goes live: touchscreen response, water resistance, phone fit and how steady it stays on broken tarmac. Rather than quote a lab rating the manufacturer never published, here is what actually happened on the bike, scored pass/fail from hands-on riding.
| What we checked | How we tested it | Result |
|---|---|---|
| Touchscreen through the window | Tapped, swiped and zoomed a live nav map, gloves off, dry hands | Full response — including fingerprint unlock |
| Wet touchscreen | Splashed water on the window, retried the map | Still readable and tappable |
| Rain / road spray | Ridden through light rain and puddle spray, then opened the bag | Interior and phone stayed dry |
| Phone fit | Tried a large-format phone in a slim case | Clean fit up to 7"; thick cases removed |
| Stability on rough ground | Cobbles and gravel, standing efforts | No sway or twist with all three straps set |
These are hands-on ride observations, not a manufacturer IP rating. Treat the Pilot as water-resistant for everyday riding, not a submersible dry bag.

|---|---|---|---|

With over 50 million Americans riding each year and e-bikes outselling electric cars in unit sales, more riders than ever are using a phone as their trip computer. A protective, phone-forward top tube bag is simply the most sensible place to put it.
"The Pilot is the bag I hand to anyone who commutes with their phone. The touchscreen window means you're never fumbling in the rain, and the hard shell has kept a screen bone-dry on rides where a fabric pouch would've soaked through. It carries the phone low and out of the wind, so the bike still feels like the bike."— Marcus Reed, Gear Editor at Ridgeline
What riders say about the Pilot
These are unedited comments from verified buyers of the phone bag. For the full set — plus reviews of the Trail frame bag — see our reviews page.
"It's perfect! The touchscreen window even reads my fingerprint to unlock the phone. Thank you."
— Verified buyer
"Impeccable — fits very well on the mountain bike and the phone stays dry."
— Verified buyer
"Highly recommended. Good price, very functional, easy to install."
— Verified buyer
One buyer noted the bag didn't suit their e-bike frame but worked perfectly on their regular bike — worth checking your top tube if you ride an oversized e-bike.
Pair it with a frame bag — and save
The Pilot handles your phone; a triangle frame bag handles everything else. The Ridgeline Trail mounts inside the frame triangle and swallows a spare tube, multitool, mini-pump, snacks and keys, all carried low and centered like the Pilot. Riders who want proper wet-weather cover on both bags should also look at our waterproof bike frame bag guide.
If you're kitting out a bike from scratch, the smartest buy is the Ridgeline Complete Kit — the Trail and the Pilot together for $44.99 (was $74.98). That's the phone-forward top tube bag plus the do-everything frame bag in one order, with free shipping and the same 30-day guarantee.

Bike top tube bag — frequently asked questions
Does the touchscreen window on the bike top tube bag actually work?
Yes. The clear window is a true touchscreen film, so you can tap, swipe and follow navigation without opening the bag. Verified buyers report it even reads a fingerprint to unlock the phone. It works with gloves off and stays responsive when the surface is wet.
What size phones fit the Ridgeline Pilot bike phone bag?
The Pilot fits phones up to 7 inches, which covers virtually every current iPhone, Samsung Galaxy and Pixel — including the larger Pro Max and Ultra sizes. Very slim cases are fine; thick rugged or wallet cases may need to come off for a clean fit behind the window.
Is the top tube bag really waterproof in the rain?
The Pilot uses a hard-shell PU/EVA body with a sealed touchscreen window, so light rain, road spray and splashes stay out and your phone stays dry. It is water-resistant for everyday commuting and showers, not a submersible dry bag — do not dunk it or ride through deep water.
Will the bag fit my e-bike or does it scratch the frame?
It mounts with three velcro straps and fits most standard round top tubes on road, gravel, MTB and hybrid bikes. Very wide or oversized e-bike frames can be a tight fit — one buyer found it did not suit their e-bike but worked perfectly on a regular bike. The soft backing sits flush and will not scratch paint.
