The Croozer Yuuna Module Lock (Kid) is a small ABUS combination padlock for securing Yuuna Kid modules (Premium Seat, Basic Seat, Baby Lounger) to the trailer.

Croozer Yuuna Module Lock (Kid)

The Yuuna Module Lock (Kid) is a small ABUS combination padlock designed for the Croozer Yuuna kid module fixings — Premium Seat, Basic Seat, and Baby Lounger. It secures the module to the trailer so it can't be lifted out and walked off with at a café or rack.

ABUS makes it, not Croozer — that's a good thing; ABUS is a well-known lock brand. It's a small, lightweight combination lock (22.5 × 52.5 × 13.5 mm, 25 g, 3 mm shackle) — designed for keyless convenience and quick deterrence, not for defeating a determined thief with bolt cutters.

Set your own code; no keys to lose.

Pro tip

This is a deterrent, not a fortress. A 3 mm shackle stops opportunist theft (kid runs off with the seat, someone unclips it in ten seconds at a rack) but won't beat bolt cutters. If you're leaving the Yuuna anywhere untended for long, lock the frame with a proper bike lock too. Set the combination on first use — factory code is 0-0-0.

Will it fit

Sized for the module fixings on the Croozer Yuuna Kid modules — Premium Seat, Basic Seat, Baby Lounger. Won't fit the Dog Module or Cargo Module (which have their own fixings). ABUS's specs work for the kid-module fixings; check Croozer's manual if you're unsure. Secures Kid modules to the Croozer Yuuna Premium Modular Bike Trailer at cafés, nurseries, or public racks.

You leave the trailer at cafés, nurseries, or public racks.

FAQ

What size lock is this?

Small — 22.5 × 52.5 × 13.5 mm, 25 g, 3 mm shackle. Deterrent-grade, not heavy-duty.

Do I need this?

Optional but sensible — Yuuna modules click out in seconds without a lock. If you leave the trailer at cafés, racks, or nurseries this stops a walk-off.

Does it fit the Dog / Cargo module?

Croozer sells it for the kid modules (Premium, Basic, Baby Lounger). The dog and cargo modules have their own fixings.

Are there keys?

No — it's a combination lock. Set your own code on first use.

Is it weatherproof?

ABUS combination locks generally handle rain fine; keep the code dial clean.
