ROCKBROS RK242 kotúčový zámok na elektrickú kolobežku - čierny

City commuters on electric scooters know the routine: stop for a coffee, run into a shop, and hope the scooter is still there when you return. The ROCKBROS RK242 disc brake lock eliminates that worry. Its push-down pin engages directly into the brake disc, immobilizing the wheel instantly. No cables to thread, no heavy chains to carry—just a compact lock that slips into a pocket or bag. Whether you ride an e-scooter, motorcycle, or bicycle with disc brakes, this lock provides a fast, reliable layer of security for every quick stop.

And because it attaches directly to the brake disc, it's always with you—no need to find a fixed object to lock to.

• Quick stops at shops, cafés, or restaurants
• Securing your scooter in a bike room or garage
• Adding a second layer of security alongside a chain or U-lock

Good to know

The RK242 comes with two flat keys, so you have a spare if one gets lost. Its compact size and light weight make it easy to carry every day, and the black anodized finish looks sharp on any ride. For maximum protection, combine it with a cable or chain lock when parking for longer periods.
