Bone Bike Tie 6 Pro stem phone mount for 4.7–7.2" phones — universal, shock-absorbing, tool-free install

Bone Bike Tie 6 Pro is a universal, shock-absorbing bike stem phone mount that secures smartphones (4.7"–7.2") to stems 28–55 mm in diameter using a patent dual cross-strap and tuckable design.

Whether you follow turn-by-turn directions, log rides, or need quick access to fitness apps, this stem-mounted holder keeps your device front-and-center without drilling, clamping, or bulky hardware. Engineered for cyclists who want easy installation, vibration damping, and a tidy fit, the Bike Tie 6 Pro pairs elastic silicone with a locking strap system to hold phones firmly on road, gravel, and commuter rides.

How does the Bike Tie 6 Pro attach to different bike stems?

The mount uses an adaptable base that wraps around stem circumferences from 88 mm to 173 mm (28–55 mm diameter). Its anti-slip treated surface increases friction and the tuckable strap keeps excess material out of the way for a clean, snag-free setup. Installation requires no tools and can be completed in seconds.

• Fits stems 88–173 mm circumference (28–55 mm diameter).
• Anti-slip treated contact area prevents rotation under load.
• Tuckable strap design conceals extra length for a neat finish.
• Quick, tool-free installation and removal for multi-bike use.

Will my phone stay secure over rough terrain?

The Bike Tie 6 Pro combines a patented dual cross-strap with a positive locking mechanism for greater retention compared with single-strap holders. High-grade elastic silicone cushions shocks and isolates vibrations, while reinforced stretch straps hold phones steady even with a protective case on.

• Patented dual cross-strap locks phone from two directions.
• Shock-absorbing silicone reduces vibration transfer to the device.
• Reinforced straps expand to fit phones 4.7"–7.2" securely.
• Designed to minimize bounce and prevent accidental release.

Does it fit my phone model and case thickness?

Designed for broad compatibility, the stretchable straps accommodate most modern smartphones between 4.7 and 7.2 inches, including many popular iPhone and Android models. The elastic material and reinforced construction allow for safe use with common slim-to-moderate cases, though extremely bulky protective cases may require a size check.

• Compatible with phones from 4.7" up to 7.2" diagonal screen size.
• Works with most slim and moderate cases; oversized armor cases may need removal.
• Reinforced strap prevents overstretch while preserving fit flexibility.
• Suitable for navigation, fitness apps, and hands-free calls while riding.

How does the design protect my phone from damage?

The silicone material is chosen to absorb impacts and guard against scratches where the phone contacts the mount. The strap layout keeps the back and corners supported, and the mount’s low-profile placement on the stem reduces exposure to road spray and debris compared with handlebar mounts.

• High-grade silicone cushions bumps and reduces vibration stress.
• Anti-scratch surfaces protect phone finish and camera lenses.
• Low-profile mounting position lowers exposure to shocks and elements.
• Secure straps reduce movement that can cause chip or crack risk.

Who this is for: Cyclists who want a fast, secure, and tidy phone mounting solution on the stem will appreciate the Bone Bike Tie 6 Pro. Ideal for commuters, road riders, gravel enthusiasts, and e-bike users who need reliable device access for navigation or tracking without heavy hardware. If you switch phones or bikes often and want no-tools installation plus strong vibration protection, this mount delivers that balance of convenience and security.
