Finding a true waterproof motorcycle phone mount or weather-sealed motorcycle phone holder is harder than it looks at first glance. Many riders assume any heavy-duty cradle will survive a downpour, but once you inspect how water, wind pressure, and road spray hit a handlebar at highway speed, the reliable choices narrow quickly. More importantly, rain-ready mounts fall into two distinct mechanical categories that suit very different riding environments. Choosing the wrong design means compromising either wet-weather protection or everyday screen usability.
Quick Answer: For regular riding in heavy rain, choose the iMESTOU IP67 Enclosed Mount (Size S for phones up to 6.1 inches; Size L for phones up to 6.8 inches), which pairs a sealed hard case with a 1-inch RAM-compatible ball base and anti-theft lock. Pick the Kewig IP66 Waterproof Mount if you want a built-in sun visor to cut screen glare, the SPORTLINK IP68 Mount if you want a model-specific waterproof housing for an iPhone 15 Pro, or a Quad Lock Mount + Poncho if you prefer an open mount on dry days with a slip-on rain cover for passing showers.

Two Approaches to Waterproofing a Motorcycle Phone Mount
Before picking a bracket, decide whether your riding calls for a permanently sealed enclosure or an open mount with a stowable weather cover.
Fully enclosed case mounts surround your smartphone inside a gasket-sealed hard shell with a clear touch-sensitive membrane across the front. Because the phone sits inside a latched housing, road spray, mud, and wind-driven rain cannot reach the charging port, speakers, or buttons. The trade-offs are slightly firmer touch response through the plastic window, increased glare in overhead sunlight, potential heat buildup on hot summer afternoons, and bulkier dimensions on the handlebars. Most quality motorcycle enclosures carry an IP66, IP67, or IP68 rating: IP66 resists powerful water jets from any direction, while IP67 and IP68 are rated for full water submersion. For riding in heavy rain, any of those three ratings provides complete weather protection.
Open mount systems with rain covers leave your phone uncovered during dry weather and rely on the smartphone’s factory water resistance combined with a form-fitting slip-on cover when storm clouds roll in. These setups prioritize bare-glass screen visibility, cooling airflow, and compact size on sunny days, while providing wet-weather protection on demand. The Quad Lock mounting system paired with its clear TPU Poncho is the best-known example. While a slip-on cover is not a hermetically sealed enclosure, it is often the more practical daily setup for commuters who only ride through occasional rain showers.
Important: If you tour or commute in heavy rain regularly, choose a fully enclosed IP66, IP67, or IP68 case mount. If you ride mostly in dry weather and want maximum screen visibility and cooling airflow, choose an open mount with a removable rain cover.
Best Fully Enclosed Mount: iMESTOU (IP67)
The iMESTOU Anti-Theft Waterproof Motorcycle Phone Mount is our top overall enclosed pick because it combines an IP67-rated polycarbonate housing with a heavy-duty aluminum mounting arm and a 1-inch (B-size) ball interface. Unlike light-duty bicycle pouches that wobble at highway speeds, the iMESTOU enclosure clamps shut with perimeter latches over a perimeter O-ring seal, keeping water and dust out while maintaining touchscreen and Face ID functionality through the clear PET front window.
Its mechanical hardware is purpose-built for motorcycle cockpits. The mount uses a standard 1-inch ball system with a double socket arm, giving you 720-degree dual-ball articulation and cross-compatibility with 1-inch RAM B-size bases and arms. A keyed anti-theft security knob locks the socket arm so the enclosure cannot be unscrewed from the bike when parked. The included aluminum handlebar clamp fits 7/8-inch (22mm), 1-inch (25.4mm), and 1.25-inch (32mm) round bars using supplied sizing rings, and the kit also includes a mirror-stem tab for mounting under a rear-view mirror base.
Because the hard shell is a fixed internal volume, choosing the right case size is critical:
- Size S (up to 6.1-inch phones): Fits devices measuring up to 5.9 inches tall, 2.9 inches wide, and 0.39 inches thick (150 x 75 x 10 mm).
- Size L (5.5-inch to 6.8-inch phones): Fits devices measuring up to 6.6 inches tall, 3.2 inches wide, and 0.39 inches thick (168 x 82 x 10 mm).
Always measure your phone with its protective case installed against those internal dimensions before ordering. If you use a thick armor case that pushes total thickness past 0.39 inches, you may need to place the bare phone or a slim case inside the iMESTOU shell.
Size S (Phones up to 6.1 inches):
Size L (Phones 5.5 to 6.8 inches):
Best Enclosed Mount With Sun Visor: Kewig (IP66)
The Kewig Waterproof Motorcycle Phone Mount carries an IP66 weather rating, meaning it is sealed against dust and powerful water jets from heavy rain, and it adds a practical feature that most enclosed cases lack: a molded top sun visor above the upper bezel. Overhead glare reflecting off the clear plastic touch panel is one of the most frequent rider complaints with enclosed phone boxes, and the Kewig’s brow helps shade the upper half of the display.
The Kewig attaches via a cast aluminum alloy handlebar clamp that fits 22mm to 32mm (7/8-inch to 1.25-inch) round bars and uses a 360-degree swivel joint so you can angle the screen in portrait or landscape orientation. Inside the ABS and silicone-lined housing, an internal spring-loaded backing plate presses your phone gently against the clear front TPU touchscreen film so your finger taps register cleanly without air gaps. The back of the case also includes a transparent window for the phone’s rear camera and a sealed bottom pass-through grommet so you can route a USB charging cable in dry or light-mist conditions.
The Large configuration linked here fits smartphones from 5.5 to 7.0 inches diagonally. While IP66 sits one step below IP67 on the ingress chart because IP66 tests against high-pressure water spray rather than full underwater submersion, both ratings provide more than enough protection for highway downpours.
Best Model-Specific IP68 Enclosure: SPORTLINK (IP68)
The SPORTLINK Waterproof Motorcycle Phone Mount steps up to an IP68 waterproof rating, the highest standard ingress protection level for consumer enclosures, designed to withstand prolonged submersion as well as heavy rain, snow, and mud. Rather than putting a small phone inside an oversized universal box with foam shims, SPORTLINK builds form-fitting waterproof cases tailored to specific phone dimensions alongside an aluminum handlebar mount.
The kit pairs a sealed polycarbonate and TPU waterproof case with a CNC-machined aluminum handlebar clamp that fits 22mm to 32mm (7/8-inch to 1.25-inch) handlebars. It features a 360-degree rotatable head, a 1-second quick-release latch so you can take the sealed phone with you at fuel stops without unbolting the bracket, and full Face ID and touchscreen support through the integrated front screen protector. Because the enclosure is molded to the phone’s exact button and camera layout, it looks and feels much slimmer on the bars than a universal hard box.
Fitment check before ordering: The exact Amazon listing linked here is built specifically for the bare iPhone 15 Pro (6.1-inch). If you ride with a different iPhone generation or a universal phone size, make sure to select the matching device variant on the product page before checking out, and install the phone without a secondary case so the waterproof perimeter seal closes completely.
Best Open Mount With Rain Cover: Quad Lock + Poncho
Quad Lock takes the opposite approach to weather protection. Instead of keeping your phone locked inside a permanent plastic box on sunny days, you ride with a standard Quad Lock mount and model-specific Quad Lock case in normal weather, and keep the Quad Lock Weather Resistant Poncho tucked in your jacket pocket or tank bag. When rain starts, the crystal-clear TPU skin slips right over the front and edges of your Quad Lock case in seconds without interfering with the rear twist-lock mount interface.
The major everyday advantage over an enclosed box is heat management and screen clarity. In fair weather, your phone screen stays completely uncovered with zero plastic glare and full airflow across the chassis. Even when the Poncho is slipped on during a storm, the soft TPU membrane sits directly against your screen and side buttons, preserving volume-button feel and Face ID recognition while sealing the charging port and mute switch against mud, dust, and rain spray.
Another important advantage of building around the Quad Lock ecosystem is camera protection. Enclosed hard cases mounted on rigid aluminum arms transmit engine buzz straight into your phone, whereas Quad Lock lets you bolt their elastomer Vibration Dampener directly between the mount base and locking head to protect optical image stabilization (OIS) camera sensors.
Important: Remember that the Poncho is only the slip-on weather cover, not a standalone mount. It requires a compatible model-specific Quad Lock Case and a Quad Lock motorcycle mount (sold separately). Quad Lock makes form-fitting Ponchos for iPhone and Samsung Galaxy S-series cases, but does not offer a Poncho for Google Pixel cases or the adhesive Universal Adapter. Also remove any thick tempered-glass screen protector if it prevents the Poncho from sitting flush against the display.
Common Problems With Enclosed Waterproof Mounts
Fully enclosed waterproof cases solve water ingress, but they introduce four physical trade-offs that every rider should understand before buying.
1. Reduced Touch Sensitivity With Motorcycle Gloves
Every enclosed mount places a clear PET or TPU barrier between your finger and the smartphone glass. While modern membranes on the iMESTOU, Kewig, and SPORTLINK respond well to bare fingers, using conductive winter or waterproof motorcycle gloves through an extra layer of plastic often requires firmer presses, and multi-finger pinch-to-zoom gestures can be inconsistent while stopped at an intersection. Set your destination before latching the case shut whenever possible.
2. Heat Buildup During Summer Navigation
Running GPS navigation at 100% screen brightness while charging generates substantial internal heat. Inside a sealed, airtight waterproof box with no cooling airflow, ambient sunlight creates a greenhouse effect that can cause your phone to dim its display, throttle processor speed, or pause charging with a high-temperature warning. On hot, dry summer days, avoid charging inside a sealed case in direct sun, or remove the phone from the enclosure during extended fuel and meal stops.
3. Screen Glare and Internal Fogging
A clear plastic cover adds a second reflective surface above your phone’s glass, which can wash out map details under midday sun. Choosing a case with a top visor like the Kewig or tilting the mount slightly downward toward your chest reduces sky reflection. If humid air gets trapped inside the housing before you snap the latches shut, cold rain hitting the outside of the window can also cause interior condensation. Closing the case indoors in dry air helps prevent fogging.
4. Fixed Case Dimensions and Charging Cable Clearance
Unlike open spring cradles that expand around any phone, enclosed hard mounts have strict internal length, width, and thickness limits. A phone wearing a rugged OtterBox or SUPCASE with a kick-stand will rarely fit inside a standard waterproof shell. In addition, if you plan to plug in a USB-C or Lightning cable while riding, remember that plugging in a stiff 90-degree or long-neck cable takes up extra vertical space inside the bottom of the housing and opens the rubber port stopper.
When You Do Not Need a Waterproof Motorcycle Mount
Most flagship smartphones sold over the last several years, including the iPhone 12 and newer, Samsung Galaxy S21 and newer, and Google Pixel 7 and newer, already leave the factory with IP67 or IP68 water resistance. For riders using one of those phones on an open handlebar mount during a brief, light rain shower, the phone’s internal seals are generally capable of handling road mist on their own.
Where an enclosed waterproof mount or rain poncho earns its keep is during sustained highway downpours and multi-day touring. At 65 mph, raindrops hit an exposed phone with enough impact pressure to trigger false “phantom touches” on a wet capacitive screen, and water pooling inside an open USB-C charging port will immediately disable wired charging until the port dries out completely. If you only need a sturdy dry-weather bracket for fair-weather rides, see our best motorcycle handlebar phone mounts guide.
Regardless of which mount style you choose, always secure your setup and consider running a secondary safety tether from the phone to the handlebar when riding in rough weather or off-pavement conditions.
Frequently Asked Questions
What is the difference between IP66, IP67, and IP68 waterproofing?
The first digit (6) means the enclosure is completely dust-tight. The second digit measures liquid protection: IP66 (used by Kewig) resists powerful water jets from any direction; IP67 (used by iMESTOU) withstands full water submersion up to 1 meter deep for 30 minutes; and IP68 (used by SPORTLINK) withstands deeper or longer continuous submersion. For riding a motorcycle in heavy rain, all three ratings keep your phone dry.
Can I charge my phone inside an enclosed waterproof mount while raining?
With caution. Enclosed mounts like the iMESTOU and Kewig include a rubber-plugged pass-through port at the bottom for a USB cable, and iMESTOU also sells separate variants with built-in Qi wireless or USB chargers. However, opening a bottom rubber flap to pass a standard charging cable through in a torrential storm creates a potential path for water to wick up the cord. In heavy downpours, rely on your phone’s battery or use a sealed wireless charging setup rather than leaving a port flap open.
Does the Quad Lock Poncho keep the phone dry at highway speed?
Yes, for normal rain riding. Because the Poncho stretches tightly over the front face and wraps around the perimeter of a Quad Lock case, wind cannot peel it off at highway speeds, and it prevents raindrops from causing false screen taps or soaking the buttons. However, the back of the case remains exposed around the twist-lock mount, so it is not designed for underwater submersion.
What size iMESTOU waterproof mount should I order?
Measure the outside length, width, and thickness of your phone (including any slim case you intend to leave on it). Order the Size S if your phone is at or under 5.9 inches tall by 2.9 inches wide by 0.39 inches thick (typical 5.4-inch to 6.1-inch phones). Order the Size L if your phone measures up to 6.6 inches tall by 3.2 inches wide by 0.39 inches thick (typical 6.2-inch to 6.8-inch Plus, Pro Max, and Ultra models).
Bottom Line
If you ride through heavy rain year-round and want a true hard-shell enclosure with a sturdy 1-inch ball mount and anti-theft lock, the iMESTOU IP67 Enclosed Mount (in Size S or Size L) is the most dependable all-around choice. If overhead sun glare bothers you, the Kewig IP66 Waterproof Mount adds an integrated top visor for large 5.5-inch to 7.0-inch phones, while the SPORTLINK IP68 Mount offers a slim, model-specific sealed housing for iPhone 15 Pro riders. Finally, if you already use or plan to buy into the Quad Lock ecosystem on an iPhone or Samsung Galaxy, adding the Quad Lock Poncho gives you the best balance of dry-weather screen clarity and on-demand rain protection.
