Rhinowalk Bike Top Tube Bag Bolt-On & Strap Mount Waterproof 600D TPU Frame Bag Slim Hard Shell Cycling Storage with Charging Port, Compatible with Top Tube & Bottle Cage Mounts

This bolt-on and strap-compatible bike top tube bag is designed for riders who need flexibility without compromising stability. Unlike fixed-only systems, it offers two mounting methods: secure bolt-on installation for frames with mounting points, or strap mounting for universal compatibility. Whether you're riding a road bike, gravel bike, or commuter bike, it adapts easily. Constructed from waterproof 600D TPU material with welded seams, the bag protects your essentials from rain and road conditions. The slim aerodynamic shape ensures comfort, while the rigid shell design keeps your gear safe and organized. Perfect for storing your phone, snacks, tools, and power bank, with an integrated cable port for on-the-go charging.

• Dual Mounting Options – Bolt-On or Strap: Install directly using M5 bolts on frames with mounting holes, or use the included TPU straps for wider compatibility. Fits top tube or bottle cage positions.
• Waterproof Welded Construction: Made of 600D TPU polyester with RF-welded seams and a waterproof zipper to keep essentials dry in all weather conditions.
• Slim Profile – No Knee Interference: 5cm narrow width minimizes drag and prevents leg rub. Ideal for road cycling, commuting, and long-distance rides.
• Built-in Charging Cable Port: Convenient cable outlet allows easy charging of devices while riding with a power bank stored inside.
• Reinforced Hard Shell Design: Rigid upper panel maintains structure, protects contents, and resists deformation during daily use.
