[Autumn Foliage Cycling] A PET bottle under the saddle!? A magnetic detachable saddle bag that fits everything in

A 600ml PET bottle fits perfectly under the bicycle saddle. A convenient gear recommendation to bring along for autumn foliage cycling.

600ml PET bottle under the saddle!?

The first surprising point about this semi-hard saddle bag is where it stores your PET bottle. Usually, when it comes to drinks on a bicycle, the standard is a bottle cage mounted on the frame, but OsmaR uses a style that stores it under the saddle.

It fits not only 500ml bottles, but also the slightly larger 600ml PET bottles that have become common lately. A drawcord secures the bottle’s neck in place. Even on mini velo bikes or folding bikes, where there’s limited room to attach a bottle cage, you can make use of the space under the saddle.

Take your bike and go cycling a little farther afield. Keeping your drink under the saddle and riding light is nice too. Still, if you pull a PET bottle out from under the saddle, first-time viewers will probably be surprised and say, “It was in there!?”

Click! Magnetic attachment means you can carry the bag around too

Another feature is the magnetic mounting mechanism. Attach the dedicated adapter to the saddle rails, and when you bring the bag close, it locks in place with a click thanks to magnets. The bag itself also has a release button. The magnetic attachment’s standalone holding force is about 200N. In addition, the seat post side is secured with Velcro to reduce bag sway while riding.

And another appealing point is that it can be easily detached. For example, when stopping by a café during a cycling trip. Undo the Velcro and magnetic lock, and you can quickly remove the bag from the bike. No need to fumble out your wallet or smartphone; just take the whole bag with you into the shop. It’s a bag that attaches to your bike, yet it’s designed with what you’ll do after parking in mind too.

A vivid red interior adds a nice accent

OsmaR’s exterior is finished in black, but when you open the zipper, the inside is a vivid red. The black-and-red combination can’t help but look cool. What’s more, the interior uses red brushed material, which also helps you find stored items more easily. The inside is divided into two sections, so you can store drinks and small items separately. Next to the PET bottle, you can keep your wallet, portable tools, and a flat tire repair kit together.

If you’re heading out far on your bike, you’ll want to bring portable tools and a flat tire repair kit. Being able to carry those tools together with your drink seems convenient. Simple black on the outside, vivid red on the inside. There’s a playful touch even in the parts you don’t usually see.

Making effective use of the often-overlooked space under the saddle

The bag uses EVA that has been thermoformed and press-molded. Because it has a semi-hard structure, it’s designed to keep its three-dimensional shape even when it isn’t full. Since it hangs under the saddle, that beautiful shape is something worth valuing. The exterior uses 600D polyester oxford, and it also features a waterproof zipper and water-repellent construction. The simple black design seems like it would suit not only Brompton, but also road bikes and gravel road bikes.

Carry your drinks, store your wallet and tools too, and still keep your bike’s silhouette neat and tidy. It’s eye-opening to see how much use can be made of the small, often-overlooked space under the saddle. The enjoyment of customizing a bike is likely to grow by one more thing.
