ROCKBROS 21oz Leakproof Bicycle Water Bottle

Better Materials for Healthy Concern

We take all food health issues seriously, ensuring every aspect of our design prioritizes your well-being. Our bike water bottle uses food-grade silicone for the bottle spout, ensuring safe and hygienic water contact. The PP5 material of the body can withstand high temperatures up to 75°C, preventing the melting of plastic and the release of toxic substances.

Easy Squeeze to Intake More Fluid

The PP5 material not only ensures durability but also grants ease of use. The bottle's body allows effortless squeezing, enabling you to intake more water with less effort. Paired with a large bottle spout, this design supports quick hydration, keeping you on your game during exercise or cycling.

Optimized Size to Fit All Cages

Our unique body size, designed for flexibility, ensures compatibility with most bottle cages on the market. The diameter of 7.4cm (2.9 inches) makes it easy to find the perfect fit, allowing you to choose your ideal cycling gear without worrying about its size.

Laminated Foam for Insulation Over 5 Hours

Insulation is a crucial feature, especially in extreme weather conditions. This water bottle uses polyethylene foam in the interlayer to maintain water temperature. Our tests show that it keeps ice cubes from melting for more than 5 hours in summer, ensuring you stay hydrated and comfortable.

High Flow & Self-Sealing Bottle Spout

This bottle not only boasts a high flow rate due to its large spout but also features a self-sealing design. Pull the spout to unlock the seal and press it to close the opening, making it easier to control the flow. For added convenience, a dust plug is included with the bottle.
