Bone Bike Tie 6 Pro, Bicycle Phone Mount for Stem

What buyers think

Buyer-review evidence points to the same practical themes: installation is straightforward (typically quick and tool-free), the silicone strap system feels secure once tightened, and the mount holds up well when going over bumps. Many comments highlight that phones stay put without noticeable rattling or shifting, and that the mount works with different phone sizes and cases within the supported range. Overall, buyer sentiment suggests this is a dependable, minimalist stem mount that prioritizes stability and protection, with limited evidence of major recurring problems.

How this stem phone mount is designed

The Bone Bike Tie 6 Pro is built around a one-piece silicone platform and strap system, rather than rigid clamps. The key feature is its dual cross-strap approach, which locks both sides of your phone for a more “captured” fit. That matters if you ride over uneven pavement, trail sections, or gravel where a less-secure mount can let a phone tilt or vibrate.

Fit and compatibility details that matter

• Stem size: Designed to fit stems with 28–55 mm diameter (88–173 mm circumference).
• Phone size: Supports smartphones from 4.7 to 7.2 inches, compatible with most iPhone and Android models listed, including with cases (as long as the phone remains within the size range).
• Mounting type: Stem mount, not handlebar clamp.

If your bike has a stem outside the listed diameter range, the straps may not tighten properly. Similarly, if your phone is outside the 4.7–7.2 inch window, it may not seat correctly or could feel loose.

Security and ride comfort

On the bike, the combination of the dual cross-strap locking design and the treated anti-slip contact surface is what you are buying. The intent is to reduce phone movement during vibration, so your navigation screen stays usable and your phone stays protected against scrapes. The silicone construction is also described as shock-absorbing, targeting impacts and bumps that can loosen mounts over time.

In buyer feedback, stability on rough rides is the most consistently mentioned benefit, alongside the lack of rattling or shifting once the straps are tightened.

Scratch protection, weather readiness, and cleaning

The mount is made from silicone and is intended to be washable. That design choice helps if you ride in rain, dirt, or wet commutes, because you can clean the mount without metal hardware components. If you live where winter grime or dusty trails are common, this washable, non-rust approach is a practical advantage.

Setup and everyday use

Installation is tool-free. The process is straightforward: position the mount on the stem, thread and tighten the straps on both sides, then tuck away extra strap length to keep the setup tidy. Once your phone is secured, the tuckable straps also reduce the chance of extra strap ends flapping while you ride.

For frequent use, this matters because you are more likely to take the phone mount on and off your bike for different rides if setup feels quick and simple.

Pros and cons summary

• You’ll likely like it if: you want a lightweight silicone stem mount with a dual locking strap system for a secure fit on bumpy rides.
• You might want to skip it if: your stem falls outside 28–55 mm diameter or your phone is outside 4.7–7.2 inches, because sizing is the limiting factor.

Verdict

The Bone Bike Tie 6 Pro is a solid choice for cyclists who prioritize phone stability and protection over complicated hardware. Its dual cross-strap locking design, shock-absorbing silicone, and non-slip treated contact surface align well with rough-road and trail use. Just double-check stem diameter and your phone’s 4.7–7.2 inch size range (including the bulk of your case) to avoid a frustrating fit issue.
