Quick Summary
The Rhinowalk bike frame bag is a black triangle bag for fitting under the tube. It is described as a 1.8 L bicycle pouch and the included size detail is 28 x 13.5 x 6 cm, so it is worth checking the available space on your frame before choosing it.
The bag is presented as a cycling accessory with a waterproof nylon build, a waterproof YKK zip and a double-sided zip compartment design. It also includes an elastic cord at the bottom and a fixed position for a portable air pump inside.

What to Compare Before Buying
- Frame space: The stated 28 x 13.5 x 6 cm size is the main fit check for this bag.
- Capacity: The capacity is stated as 1.8 L in one place and 1.7 litres in another, so compare the version you want against the space you need.
- Access on the bike: The bag is described as hiding the water bottle less on frames larger than 50 meters, with 620 ml also mentioned. That wording is unusual, so check the intended position on your own frame carefully.
- Closure and storage layout: The double-sided zip compartment design and internal pump position affect how items are arranged inside.
Choosing the Correct Version
The size shown in the product name is M, so confirm that this is the version you want before selecting an offer. The colour is black, and the stated capacity is not consistent across the supplied details, so compare the dimensions and fit with your frame space as well.
Before You Decide
Check the M version, the black colour and the stated dimensions before choosing. Compare the frame space with the bag size, and note the capacity wording differs between 1.8 L and 1.7 litres. If you want the pump position or bottle access to work as intended, confirm the layout against your own bicycle frame.
