• UPPEL Bike Phone Mount — biggest strength: one clamp-and-go unit that combines a phone holder, 5W Bluetooth speaker, double LED light and electronic horn on your handlebar.
• UPPEL Bike Phone Mount — biggest trade-off: it's a bike accessory, not personal audio. Everyone around you hears your music, and the speaker does nothing once you step off the bike.
• Piegricdiat Bone Conduction Headphones — biggest strength: open-ear sound with IPX8 waterproofing and 32GB of built-in storage, so you can ride with music and still hear traffic.
• Piegricdiat Bone Conduction Headphones — biggest trade-off: no phone mount, no light, no horn — and bone conduction sound leaks a little and skips the deep bass that in-ear buds deliver.
• Who each pick is for: UPPEL for the rider who wants everything bolted to the bars; Piegricdiat for the rider who wants audio on their head and their phone in a pocket.
The UPPEL Bike Phone Mount is a consolidation play. Instead of buying a phone holder, a light, a bell and a speaker separately, you bolt one plastic unit to the handlebar and get all four. The patented clamping mechanism holds phones from 3.5 to 7 inches wide, which covers most modern handsets — the sheet lists Apple, Samsung, Huawei, Xiaomi, Sony, TCL, Nokia, LG, HONOR, VIVO, OPPO, realme, Google Pixel and Motorola among the compatible brands. The clamp is designed so the phone stays put under intense riding, and the whole thing detaches quickly when you want to lock the bike or take your phone with you.
The audio side is more capable than you'd expect from a handlebar gadget. There's a 5W Bluetooth speaker with a soft diaphragm tuned for clarity, plus TF card, U-DISK and AUX-in inputs for people who'd rather not depend on a phone at all. Multi-function keys handle playback without you reaching for your pocket. The 5000mAh battery is the real story: 6–7 hours of continuous light, 12–15 hours of continuous music, or roughly 4–5 hours if you run both. That's enough for a long weekend ride or several commutes between charges.
Buy it if you want one tidy cockpit: navigation visible, music playing, road lit, horn ready. Skip it if you ride with earbuds or headphones already, or if you mostly ride in groups and don't want your playlist broadcast to everyone.
Piegricdiat Bone Conduction Headphones: Who It's For
The Piegricdiat set takes the opposite approach. It puts the sound on your head instead of on your bike, using open-ear bone conduction drivers that sit outside the ear canal. That design keeps your ears open to traffic, pedestrians and road noise — the single most important argument for bone conduction over sealed earbuds on a bike. It's also kinder to your ears over long sessions, since nothing is jammed into the canal.
The headline spec is IPX8 waterproofing. That's deep-water rated, covering swimming, surfing and snorkeling, with the caveat that it shouldn't stay submerged for more than six hours at a stretch. Sound underwater is described as clear and balanced. For a cyclist this matters less day to day, but it means rain, sweat and a post-ride shower are non-events. Nobody needs to baby these.
Then there's the 32GB of built-in memory. You copy songs over with the magnetic charging cable — the headphones show up like a USB drive — and then play them in MP3 mode with no phone connected at all. For cycling that's a genuinely freeing feature: no pairing, no battery drain on your handset, no notifications interrupting your ride. When you do want Bluetooth, version 5.3 handles pairing with a stable, low-latency connection and wide device compatibility.
Comfort looks well considered. Open-ear placement means no soreness after long listening sessions, and the built-in noise-reduction microphone keeps calls clear. The whale-cavity stereo surround design is the brand's language for its soundstage tuning, and the driver covers 20Hz–20,000Hz at 8 ohms. Controls are physical buttons, which I prefer on a bike — you can find them by feel with gloves on. Rated battery life is 6 hours. The model is the X16 in Deep Black, with a 1-year warranty.
Buy it if you want music on every ride without blocking your ears, and you like the idea of swimming or showering with the same pair. Skip it if you need maximum bass, want active noise cancelling (there is none), or want your phone visible on the bars.
Side-by-Side: Which Should You Choose?
• Best for keeping your phone visible for navigation → UPPEL Bike Phone Mount. The adjustable clamp handles 3.5–7 inch phones and detaches fast.
• Best for hearing traffic while you ride → Piegricdiat Bone Conduction Headphones. Open-ear design keeps your surroundings audible.
• Best for rain, sweat and water → Piegricdiat Bone Conduction Headphones. IPX8 is a far higher waterproofing bar than a general waterproof rating.
• Best for riding without your phone → Piegricdiat Bone Conduction Headphones. 32GB of onboard storage and MP3 mode mean no handset required.
• Best for night visibility and warning others → UPPEL Bike Phone Mount. A 50m LED beam plus a three-tone, adjustable-volume horn.
• Best for shared or group rides → Piegricdiat Bone Conduction Headphones. Your music stays yours instead of broadcasting from a handlebar speaker.
• Best for a single tidy cockpit setup → UPPEL Bike Phone Mount. Mount, light, speaker and bell in one 0.58 kg unit.
For pure cycling, I'd buy the Piegricdiat Bone Conduction Headphones. Open-ear audio is the right call on a bike — you get music without cutting yourself off from the road, IPX8 means weather is irrelevant, and 32GB of built-in storage removes your phone from the equation entirely. The UPPEL is the better buy only if your priority is navigation on the bars plus lighting and a horn in one package. If you already own a light and a bell, the UPPEL's value drops sharply; if you don't, it's a genuinely clever all-in-one. Check the current price on Amazon before deciding — the gap between them may settle it for you.
It fits phones between 3.5 and 7 inches wide and lists Apple, Samsung, Huawei, Xiaomi, Sony, TCL, Nokia, LG, HONOR, VIVO, OPPO, realme, Google Pixel and Motorola among supported brands. If your phone falls in that width range, it should clamp in fine.
Can I use the Piegricdiat bone conduction headphones for swimming as well as cycling?
No. They have 32GB of built-in memory, and you load tracks by connecting the magnetic charging cable to a computer and copying files across. MP3 mode then plays everything without any Bluetooth connection.
The UPPEL lasts longer in absolute terms — 12–15 hours of music alone, or 4–5 hours with the light running too, from a 5000mAh battery. The Piegricdiat is rated at about 6 hours, which is plenty for a typical ride or a swim session but not a multi-day tour.
