Drink holders commonly mount to the handlebar, to the seat post, or to a base that attaches to either the handlebar or seat post.
Many listings include mounting hardware such as screws, washers and a small wrench; some packages also include a mounting base or gaskets.
Sling-style carriers are often insulated and water-resistant, with multiple pockets for keys, phone and wallet, a drawstring closure to secure the bottle, and an adjustable, detachable shoulder strap for carrying.
Mounting requirements vary by model, so check the product's listed base or mounting-hole dimensions. Examples in listings include base hole diameters of about 14–40 mm and cup‑holder mounting hole pitch values around 5.5–6.5 cm.
