Hamax Cocoon double-seat bike trailer

The Hamax Cocoon double-seat bike trailer is a compact multisport twin carrier — bike trailer, stroller and (with accessories) jogger and ski-sled. It seats two children side-by-side, each up to 22 kg or 117 cm, from roughly nine months old once they can sit unsupported. Grey/Black finish, article 400235.

The Cocoon's headline trick is how small it folds: 98 cm long, 66 cm wide, just 32 cm tall — meaningfully smaller than the Outback Next's pack. A hatchback boot that wouldn't take an Outback will usually take a Cocoon. The 17 kg trailer keeps weight down for the same reason. Inside, both seats recline independently through three positions, and a telescopic vegan-leather handle bar adjusts to the adult pushing. A factory-fitted drum brake on the rear axle handles long descents, so you won't be buying a disc-brake upgrade later.

One honest caveat: the Cocoon's stroller wheel is not air-filled and has no suspension, the outer fabric is not replaceable, and there's no extended frame warranty — those upgrades sit on the Outback Next instead. Worth knowing before you decide which Hamax fits your family.
