Bicycle phone holder CNC aluminium alloy mounting bracket fits handle diameters up to 31.8 mm designed for mobile phones 55-100 mm wide available in Black Gold Titanium colours
Aluminium Alloy Bicycle Phone Holder for Handlebars up to 31.8 mm and Phones 55-100 mm Wide

This bicycle phone holder offers a practical mounting solution for cyclists who rely on their smartphones for GPS navigation, tracking fitness metrics, or controlling music while on the move. Constructed via CNC machining from aluminium alloy, it is designed to balance strength with a light weight, aiming to provide a secure fit without adding significant bulk to your handlebars. The holder's key specifications are clearly defined: it fits phone widths from 55 mm to 100 mm and clamps onto handlebars with a maximum diameter of 31.8 mm. Available in Black, Gold, and Titanium colour finishes, it provides a functional accessory compatible with a wide range of standard bicycle models and modern smartphones.
Features and Construction

The design of this holder centres on delivering a reliable and compatible mounting point for your device. Its construction and sizing are tailored to meet common bicycle and smartphone standards, providing a straightforward fit for many users. The emphasis is on the practical interplay between the chosen material, the manufacturing process, and the resulting product dimensions.
Material and Build
The holder is fabricated from aluminium alloy using a CNC (Computer Numerical Control) machining process. This method allows for precise cutting and shaping, resulting in a component with consistent tolerances and a clean finish. The aluminium alloy contributes the stated properties of high strength relative to its weight and oxidation resistance. This resistance to oxidation is a practical advantage for a cycling accessory, as it helps the holder maintain its appearance and structural integrity when exposed to outdoor elements like rain and road spray, without requiring claims about specific waterproofing or impact resistance.
Size and Practical Fit
The holder's compatibility is defined by two key measurements. First, it accommodates mobile phones with widths between 55 mm and 100 mm, covering most smartphones from compact models to larger premium devices. Second, its clamping mechanism is designed for bicycle handlebars with a diameter of 31.8 mm or less. This diameter is a common standard for many road, hybrid, and mountain bike handlebars, making the holder widely applicable. The product description does not specify if the clamp is adjustable for smaller diameters or if it includes rubber shims for a snugger fit on thinner bars.
Uses and Placement

This holder is intended for the specific function of securing a smartphone to a bicycle's handlebars. This placement allows for at-a-glance visibility of the screen, which is useful for several cycling scenarios. The design's compatibility with standard handlebars and a broad range of phone sizes supports its use across different types of riding and equipment setups.
Event or Professional Use
For cycling events, long-distance touring, or professional training, reliable access to navigation and performance data is crucial. A securely mounted phone running route-mapping apps like Komoot or Google Maps, or fitness trackers like Strava, allows riders to follow pre-planned courses without stopping to check directions. The holder's aluminium alloy construction and secure clamp aim to keep the device stable even over rough terrain or during vigorous riding, though specific vibration damping features or load limits are not detailed in the source text.
Everyday Home Use
For commuters, leisure cyclists, or those using a bike for local errands, the holder provides a convenient way to have a phone accessible. It can be used for turn-by-turn navigation to a new cafe, controlling a music or podcast playlist hands-free, or simply having the phone ready to answer a call via headphones. The light weight of the aluminium alloy means it adds minimal extra weight to the bike's cockpit, and the oxidation-resistant finish is a practical benefit for bikes stored in sheds or on balconies where they might be exposed to damp conditions.
Benefits and Buying Value

The value of this phone holder lies in its defined compatibility, material choice, and the practical benefits these offer. It addresses the specific need for a secure mounting point without overpromising on unspecified features. The focus is on the concrete advantages supported by the provided information.
Reuse and Low Maintenance
The durable nature of CNC-machined aluminium alloy suggests the holder can be used across multiple bikes or seasons. Its oxidation resistance reduces the need for frequent polishing or treatment to prevent rust, aligning with a low-maintenance profile. The simple, mechanical clamp design means there are no batteries to replace or electronic components that could fail, supporting long-term reuse as long as the phone and handlebar size requirements remain compatible.
Why Choose This Product
This product is a suitable choice for cyclists who need a phone holder with clear, stated size parameters (55-100 mm phone width, ≤31.8 mm handlebar diameter) and a construction method (CNC aluminium alloy) known for precision and strength. The availability of three colour finishes (Black, Gold, Titanium) allows for a degree of personalisation to match your bike's aesthetics. It represents a functional solution based on measurable specifications rather than unspecified premium claims, making it easier to assess fit and suitability before purchase.
