## Long description

Under-frame bike bag ER4 RIDER105G with bottle pocket, grey — under-frame pannier for cycling essentials is a compact storage solution that mounts beneath the top tube of the bicycle frame. Constructed for everyday cycling, it holds tools, a phone, keys and includes a dedicated bottle pocket for a small water bottle. The bag uses zip closure and adjustable frame straps to ensure a secure fit on road and city bikes without obstructing pedaling or shifting.
Advantages
The slim profile keeps weight centralized and low on the frame, improving ride balance while providing quick access to essentials. Durable outer material resists light splashes and abrasion from routine use. A zippered main compartment secures contents and the integrated bottle pocket separates hydration from tools to prevent spills. Attachment straps are adjustable for stable mounting on different tube shapes and sizes.
Suitable for
Daily commuting where compact storage for phone, keys and tools is required
Urban and road cycling with limited frame space
Short tours and repair-kit transport under the top tube
Riders who prefer a low-profile bag that does not interfere with pedaling
Key specifications
Position: under top tube / underside of frame
Primary material: water-resistant fabric and reinforced seams
Closure type: zippered main compartment
Accessory pocket: integrated bottle pocket for small bottle
Attachment: adjustable velcro/strap fasteners for secure mounting
Color: grey
Form factor: slim, low-profile design
How to use
Attach the bag to the underside of the top tube using the adjustable straps, positioning it so it does not contact the knees while pedaling. Place small tools, a spare tube, multi-tool, phone and keys into the main zippered compartment, and insert a small water bottle into the dedicated bottle pocket. Ensure all straps are tightened and the zipper is fully closed before riding. Periodically check fastenings and seams for wear and retighten straps if necessary.
Usage recommendations
For best results, mount the bag slightly forward of the seat tube to keep pedal clearance and balance load with items in other bags or pockets. Avoid overloading beyond the bag’s slim capacity to prevent interference with cables and shifting; remove the bag for pressure washing or prolonged rain exposure to extend fabric life.
