The Kewig CBK-4 combination helmet lock clamps to a bare 22, 25.4 or 28.6 mm handlebar. Three dials and a 49.5 cm coated steel cable hold the helmet on the bike, with no key to open it. It stops a quick grab; BigBike makes no promise against cable cutting. Price 495,000 VND.
Keyless lock
At the cafe, a full-face helmet takes up a whole seat. The 49.5 cm coated steel cable threads through the D-ring on the helmet strap. Hook the cable end into the lock body and scramble the three dials. To open, turn to the right code, flick the latch on the side and pull the cable end out. BigBike has test-locked one full-face helmet and two helmets at once. The lock stays on the bike, with no key to forget.
Set your code
The factory code 000 is known to everyone, so change it as soon as the lock arrives. With the lock open, press the pinhole button on the back with a pin or a paper clip. Turn the three dials to the new code, release the button and write the code down. BigBike has changed the code successfully. This lock stops a quick grab at the cafe; BigBike makes no promise against cable cutting.
Fitting
The bike needs a bare round tube of 22, 25.4 or 28.6 mm.
Pick the spacer → Wrap the lock body → Tighten the hex bolt → Set the code → Thread the D-ring → Scramble the three dials.
BigBike has test-clamped all three tube sizes. Scooters with covered handlebars have no bare tube, so use the Kewig BD-1S bungee to strap the helmet to the rear seat. The box holds the lock body, the 49.5 cm coated steel cable, two spacers and a hex key.
The lock body stays on the handlebar, you open it with a code instead of carrying a key.
One coated steel cable locks two helmets at once.
Change the code with the pinhole button on the back, no mechanic needed.
The 210 g aluminium body clamps firmly to the handlebar with a hex bolt.
BigBike makes no promise against cable cutting.
Scooters with covered handlebars have nowhere to clamp the lock body.
You must change the factory code 000 before use.
BigBike makes no promise on how much load the lock will take.
