Waterproof Bicycle Bag with Large Capacity Top Tube Bag Made of TPU

Meet the OFFBONDAGE Waterproof Bicycle Bag, a must-have top tube bag crafted from durable TPU fabric. Designed for rainy days, it keeps your essentials dry and secure while you ride, so you can focus on the road ahead. The high-density waterproof material, sealed zipper, and seamless construction shield your phone, keys, and identification documents from rain, splashes, and spray, giving you peace of mind in wet weather.

This bag goes beyond simple storage. Its 3D solid and sturdy design features a built-in detachable folding support plate, so the bag stays rigid and won’t collapse under pressure or on rough roads. On bumpy descents or during sprinting, it remains stable and reduces wobble, helping you maintain control and comfort. With two installation options—screw fixation for a more permanent setup and strap fixation for frames of various shapes—you can tailor the installation to your bike and riding style.

Carrying capacity is generous, and access is effortless. The waterproof zipper opens smoothly for single-handed operation, making it easy to grab a phone, gel, tools, or cards without stopping. The anti-slip base keeps the bag firmly in place, while the lightweight design (only 152 grams) adds no extra burden. Available in Vitality Orange for high visibility on dreary days, or Classic Black for a versatile, low-key look.
