WEST BIKING Waterproof Bicycle Phone Bag — Fits Phones to 6.0"

Your Phone Sealed Behind a Zip, Readable Through the Cover, With a Sun Hood and a Reflective Frame. Built for the Ride Home in the Rain.

An open clamp holder is fine in July. In a Canadian October it hands your phone to the weather — rain, road spray off the front tire, and salt fog for the last half of the season. The WEST BIKING Waterproof Bicycle Mobile Bag takes the opposite approach: a fully enclosed shell that zips shut, with a TPU window your touchscreen still reads through, so navigation and music keep working while the phone stays sealed.

Three details lift it above a plain dry bag. There is a moulded sun hood over the top of the window, which is the difference between a readable map and a mirror when low autumn sun is behind you. There is a reflective strip framing the window, sitting high on the bars and facing forward — useful on a commute that ends in the dark from October onward. And there is an earphone port with a 3.5 mm right-angle extension cable in the box, so wired audio runs out without breaking the seal. The mount sits on a swivel base that rotates a full 360° between portrait and landscape.

Why an Enclosed Bag Beats an Open Clamp Once the Weather Turns

• A zip is a seal; a clamp is not. An open holder grips the four corners of a bare phone and leaves the screen, ports and speaker grilles exposed to everything the front tire throws up. The failure mode is not dramatic, it is gradual — water in the charge port, corrosion in the speaker mesh. The zip closes that off entirely.
• The sun hood is the feature nobody thinks about until they need it. A phone screen behind a plastic film is a mirror at the wrong angle. The moulded peak over the top of the window shades it, which is exactly what you want riding west at 5pm in October with the sun low in front of you.
• Reflective trim that sits high and faces forward. Most reflective gear a rider owns points backward or sideways. This sits on the bars, facing the traffic ahead of you, at roughly headlight height for a car. It is not a light — it only works when something shines at it — but it is free visibility in a position where you have almost none.
• You keep wired audio without breaking the seal. The earphone port and the included right-angle extension cable mean you are not choosing between waterproofing and headphones. On an eBike, where hearing traffic matters, a single earbud on a wired cable is a far more reliable arrangement than fumbling with a sealed bag.

Key Features

• Fully Enclosed Shell with Waterproof Double Zipper — The phone goes inside and the bag zips shut. West Biking specifies a waterproof double zipper and states the bag is 100% waterproof; they publish no IP rating, so treat it as rain-and-spray capable rather than submersible. This is the core of the product — everything else is refinement.
• TPU Touchscreen Window — A clear film front that your capacitive screen reads through, so maps, music and calls all work with the bag closed. Expect fingerprint and face unlock to be unreliable through the film — a tappable passcode is the practical workaround.
• Moulded Sun Hood — A peak over the top edge of the window that shades the screen against low sun and glare. West Biking calls this the “sunscreen cover design” on their own listing.
• Reflective Window Frame — A reflective strip runs around the border of the screen window. West Biking’s own night photography shows it returning light strongly.
• Earphone Port and Included Extension Cable — A dedicated port in the shell plus a 3.5 mm right-angle extension cable in the box, so wired audio runs out of the sealed bag without a gap.
• 360° Swivel Handlebar Mount — The bag sits on a strap-and-clamp base with a rotating joint, so you can move between portrait for navigation and landscape for video without unmounting. Two adhesive-backed velcro pads are included alongside it.
• Quick Install and Removal — The bag comes off the mount without tools, which matters more than it sounds: a phone bag left on a parked bike is an advertisement.

The Honest Take — What We’d Change

Three trade-offs worth knowing before you buy:

1. The 6.0″ phone limit is genuinely restrictive, and it is the reason most returns on a product like this happen. Both other phone mounts we stock take larger phones — 6.7″ for the enclosed holder, 7.2″ for the open clamp. If your phone is a large-format model, this bag is simply the wrong product and no feature on it compensates. Measure first. We have put this warning in four places on this page on purpose.
2. “100% waterproof” is a manufacturer claim with no IP rating behind it. The enclosed-and-zipped design is obviously more protective than an open clamp, and we have no reason to doubt it sheds rain well. But an unrated claim is not a tested one, and we are not going to present it as though West Biking had certified it. Ride it in rain with confidence; do not drop it in a lake.
3. West Biking publishes almost no hard numbers. No dimensions, no capacity, no weight, no fabric name, no handlebar diameter range, no IP rating. For an accessory at this price that is not unusual, but it does mean you are buying on design and photographs rather than a spec sheet. If a specific measurement matters to your setup, call us before ordering rather than guessing — we would rather answer the question than take the return.

Those trade-offs are worth accepting for one specific rider: someone with a phone at or under 6.0″ who commutes year-round in real weather and is tired of a bare phone clamped in the rain. For that rider this is the most protective phone mount in our catalogue at any price.

Who Is This Bag For?

• Year-round commuters with a phone 6.0″ or under — This is the intended buyer and the one the product genuinely serves. If you ride through Canadian autumn and winter and navigate from your phone, sealing it behind a zip is the upgrade that matters. See our Canadian winter eBike guide →
• Delivery riders — Constant screen use, constant weather exposure, and a phone that stops the shift if it dies. An enclosed mount with a sun hood and wired-audio passthrough is working equipment here, not an accessory. See our delivery eBike guide →
• Riders who want visibility without buying more gear — The reflective window frame sits high and forward-facing. It will not replace lights, but it adds a reflective surface exactly where you have none.

Who it’s NOT for: Anyone with a phone larger than 6.0″ — buy the Enclosed Adjustable Holder (6.7″) → or the 360° One-Touch Holder (4.5″–7.2″) → instead. Riders who need to grab the phone constantly in seconds — an open clamp is faster than a zip, every time. Riders who unlock by fingerprint or face and will not switch to a passcode — a TPU film interferes with both. Anyone wanting real cargo capacity — this holds a phone and very little else; browse bags and accessories at Zeus →.

Frequently Asked Questions

Will my phone actually fit? (Read this one first)

West Biking rates this bag for phones 6.0″ and under. That is the tightest limit of the three phone-carrying options Zeus stocks, and it rules out a lot of current handsets — plenty of modern phones are larger than 6.0″, and a thick case makes the fit worse. Check your phone’s screen size before you order rather than after. If it is over 6.0″, do not buy this bag: the Enclosed Adjustable Universal Ebike Phone Holder → takes screens up to 6.7″, and the 360° One-Touch Holder → takes 4.5″ to 7.2″. We would rather send you to a different product than take a return.

Is it genuinely waterproof?

West Biking describes it as having a waterproof double zipper and states it is 100% waterproof. That is their claim, not a tested Zeus figure, and they do not publish an IP rating to back it — so we are not going to repeat the number as though it were certified. What the design does give you is a fully enclosed shell with a zip closure and a TPU screen window, which is a genuinely different level of protection from an open clamp holder that leaves your phone exposed to rain and road spray. Treat it as rain-and-spray capable. Do not submerge it.

Can I use the touchscreen without taking the phone out?

Yes. The front window is a TPU film that your touchscreen reads through, so you can work maps, music and calls with the phone sealed inside. There is also an earphone port in the shell and West Biking includes a 3.5 mm right-angle extension cable so you can run wired earphones out without opening the bag. Note that fingerprint sensors and face unlock generally do not work through a film like this — expect to open the bag to unlock, or set a passcode you can tap through the window.

How does it mount, and will it fit my handlebar?

It mounts to the handlebar with an included strap-and-clamp base that sits on a swivel, which is what gives the 360° rotation between portrait and landscape. Two adhesive-backed velcro pads are also included for securing the bag body. West Biking does not publish a handlebar diameter range for this mount, so we cannot quote one — if your bars are unusually thick or an odd shape, call 1-866-938-7580 before ordering and we will help you check. For reference, the open-clamp holder Zeus stocks does publish a range: 22 to 33 mm.

What comes in the box?

Four items, all visible in West Biking’s own product photography: the bag itself, the handlebar mount with its strap and swivel base, two adhesive-backed velcro pads, and a 3.5 mm right-angle earphone extension cable. West Biking does not publish a formal packing list, dimensions, capacity or weight for this product, so this list is compiled from their photographs rather than a spec sheet — and we have marked every figure they omit as not published rather than estimating it.

Is it suitable for an eBike rather than a pedal bike?

Yes, with one caveat worth thinking about. The enclosed shell and reflective trim suit eBike use well, and the sun hood over the window helps at the higher average speeds an eBike holds. But eBikes carry more vibration through the bars than a light road bike, and West Biking does not publish a vibration or shock rating for the mount. If you ride a high-power off-road machine on rough ground, check the mount is still tight at the start of every ride. Anything with a screen bolted to a handlebar is a consumable on that kind of terrain. See our electric dirt bike guide →

Does the reflective trim actually do anything?

It is a genuine reflective strip around the window frame, and West Biking’s own night photography shows it lighting up under a light source. On a Canadian winter commute where usable daylight is gone by mid-afternoon, a reflective element sitting high on your handlebars and facing forward is worth having. It is not a substitute for lights — it only works when something is already shining at you. Pair it with a proper front light and a rear light, which are legally required after dark in most provinces. See our Canadian eBike laws guide →

What warranty covers it, and what is the return policy?

Zeus includes a 1-month complimentary limited warranty plus one month of unlimited free support from delivery, and we manage any defect claim on your behalf. We do not have a published West Biking warranty term for this specific accessory, so rather than invent one, call 1-866-938-7580 and we will confirm the current terms before you buy. Returns are accepted within 15 days on unused, unopened items, subject to a 15% restocking fee, with return shipping paid by the customer. Full terms are on the Zeus refund policy page →

Are there customer reviews for this bag yet?

Not at Zeus — this is a new addition to our catalogue and we are not going to show you review counts we do not have. What we can offer instead is a spec table where every figure West Biking does not publish is marked as not published rather than guessed, an honest warning about the 6.0″ limit, and a phone call: 1-866-938-7580. Tell us your phone model and how you ride, and we will tell you plainly whether this bag fits your situation or whether one of the two holders is the better buy.
