Mountain Bike Front Beam Handlebar Bag with Touch Screen TPU Window, Waterproof Zipper, Composite PU Construction, 18.5x9.5x9.5cm Size, Fits Bicycle Phone Storage
Bicycle Phone Bag with TPU Touch Screen and Waterproof Zipper for Handlebar Mounting

When cycling, keeping your phone within sight and reach makes a real difference to safety and convenience. This mountain bike front beam bag is built for exactly that purpose: it holds a phone up to 6.0 inches securely on the handlebars, with a TPU touch screen window that lets you tap and swipe without taking the device out. The composite PU exterior and waterproof zipper add practical weather resistance for everyday commuting, trail riding, or touring. Instead of digging in a pocket or risking a dropped phone, you can follow maps, take calls, or control music hands-free and keep both hands on the bars.
Features and Construction

The bag is designed around three core features: touch screen accessibility, weather sealing, and secure attachment. Each element is chosen to meet the demands of cycling use without adding bulk.
Material and Build
The outer shell uses composite PU, a synthetic material that offers a good balance of stiffness and flexibility while resisting scuffs from day-to-day riding. The waterproof zipper runs the full length of the top edge, helping to keep moisture out when you encounter sudden rain or road spray. Inside, the lining is smooth and non-abrasive, protecting your phone’s screen and case from scratches during vibration or repeated access.
Size and Practical Fit
Internal dimensions measure 18.5 x 9.5 x 9.5 cm, creating enough space for a phone of up to 6.0 inches along with a slim case or a few cards or keys. The compact shape sits neatly on the front beam without interfering with cable routing or handlebar grip. Because the bag is small and lightweight, it adds negligible drag and stays in place at speed.
Uses and Placement

This handlebar bag is suited to a range of two-wheeled activities where phone access and weather protection matter. Its attachment method works on most bicycle front beams.
Event or Professional Use
Cyclists taking part in sportive rides, charity events, or delivery work will benefit from keeping navigation and work apps in view. The touch screen window means you can quickly glance at a route or accept a job without stopping. The waterproof closure provides extra confidence when conditions are unpredictable, allowing you to focus on performance rather than equipment.
Everyday Home Use
For daily commuters, shopping trips, or leisure rides, the bag offers a simple way to carry your phone without a rucksack or frame-mounted phone mount. It is also handy for electric bike users who rely on a phone for battery status or ride data. The four colour options (Black, Black red, Chinese elements black, Dynamic black, Dynamic black red) let you match your bike’s aesthetic if desired.
Benefits and Buying Value

Practical features directly address the frustrations of using a phone while cycling: having to stop to check directions, worrying about rain damage, or carrying a bulky pocket that rattles. This bag solves each one with tested materials and a straightforward mounting system.
Reuse and Low Maintenance
The composite PU shell wipes clean easily with a damp cloth, and the waterproof zipper requires no special lubricants. The one-piece velcro strap stays reliable through repeated attachment cycles, making the bag simple to swap between bikes or store away when not in use. There are no batteries, electronics, or moving parts to wear out, so the bag should last through many seasons of regular riding.
Why Choose This Product
If you need a dedicated phone carrier that combines touch screen access, weather resistance, and a compact fit, this bag delivers all three without unnecessary complications. It uses a proven closure system, a widely compatible mounting strap, and a screen material known for its touch sensitivity. The design is purpose-built for front beam mounting on mountain, hybrid, road, and electric bikes, making it a versatile addition to any cyclist’s setup.
