The entry-level model U4 of the new TRELOCK U-lock series convinces, like the rest of the series, with its attractive product design. But here, too, the qualities are right. A 14 mm thick shackle made of hardened steel and a secure disc style cylinder make life difficult for bicycle thieves. The compact size of the mini version is easy to transport.
