Bike Handlebar Bag with Phone Holder — See Your GPS, Reduce Glare
A bike handlebar bag with a built-in phone holder and sun visor. Mount it on your handlebars and you can follow your GPS, change music and check messages through the touchscreen window without taking your phone out. The dedicated sun visor cuts screen glare so you can read your navigation even on bright days.
The storage area underneath holds your keys, wallet, phone cable, energy bars, inhaler or anything else you don’t want in your pockets. Redesigned this generation with a larger phone pocket that takes even the largest modern smartphones.
Will My Phone Fit?
The touchscreen window measures 19.5cm x 8.5cm and takes every current flagship, right up to the biggest 6.9 inch handsets. Phones that fit include the iPhone 17, 17e, 17 Pro, iPhone Air and 17 Pro Max, the Samsung Galaxy S26, S26+ and S26 Ultra and the Google Pixel 11, 11 Pro and 11 Pro XL, plus older models such as the iPhone 14, 15 and 16, the Galaxy S23, S24 and S25 and the Pixel 8, 9 and 10.
The very largest handsets, such as the iPhone 17 Pro Max and Galaxy S26 Ultra, are around 7.8cm wide, so they fit the 8.5cm window with a little room either side. If yours is one of those in a chunky case, measure it first. Folding phones such as the Galaxy Z Fold and Z Flip are not suitable.

Who Is This Handlebar Bag For?
Commuters
Glance at your route, keep a card and cash handy, skip the backpack. The handlebar mount puts the bag right in your eyeline.
Touring & Long Distance Riders
Follow your GPS hands-free and charge from a power bank through the pass-through opening. Extra room for snacks, a multitool and spare tubes.
Weekend & Leisure Riders
Affordable way to carry essentials on your bike. Fits standard handlebars in seconds with three adjustable velcro straps — no tools needed.
Handlebar Bag vs Phone Mount — Which Is Right For You?
A phone mount holds just your phone, clipped or clamped to the bars. This bike handlebar bag holds your phone and your essentials — keys, wallet, cable, snacks. The phone sits in a protected touchscreen window with a built-in sun visor, so screen glare and rain are no longer a problem.

Frequently Asked Questions
What handlebar sizes does it fit?
Fits standard round and oversize handlebars on most road, hybrid, commuter and mountain bikes via three adjustable velcro straps. Not designed for drop bars (the bag is sized for straight bars).
Does the sun visor actually help?
Yes. It overhangs the touchscreen window at the top and sides, cutting direct sun and sky reflections so the screen stays readable. Especially useful on low-sun spring and autumn commutes.
Is it waterproof?
It’s water-resistant. The outer material and 2-way zips are designed to keep UK showers and road spray out. Not designed for submersion or hours of sustained heavy rain.
What phone sizes fit?
The screen window is 19.5cm x 8.5cm, which takes every current flagship including the largest 6.9 inch models such as the iPhone 17 Pro Max, Galaxy S26 Ultra and Pixel 11 Pro XL. Those widest handsets are about 7.8cm across, so measure yours first if it is in a chunky case. Folding phones are not suitable.
Can I use the touchscreen through the window?
Yes — swipe, tap, pinch and zoom. Works with Google Maps, Strava, Komoot, Spotify and most apps. Face ID through the PVC can struggle in direct bright sunlight.
Will it affect my steering or cabling?
The bag sits centrally between your hands ahead of the stem. On bikes with routed cables at the front you may need to reposition the straps — easy to do without tools.
How stable is it at speed?
Very stable with the 3-strap mount. Most riders report no bounce or wobble on normal roads. For heavy off-road riding a dedicated hardshell mount may be better.
