Ulock Intro

NEW TRELOCK U-LOCK SERIES – MAXIMUM SECURITY IN A NEW DESIGN

U-locks are among the most secure bicycle locks. Especially Trelock locks – as underlined by the Stiftung-Warentest-Test 08/2017. Here, the TRELOCK U-lock LEVEL 6 with 300 mm shackle, the BS 650, was proven to be the best and most secure bicycle lock in the entire test. TRELOCK has now redesigned the complete U-lock series and added new models. The name has been changed: The BS 650 is now called U6 and comes in a new Trelock design with the usual reliable features and the recognition of the BS 650‘s „Stiftung Warentest“. The BS 450 is the new U4 Plus and also retains its unique functions such as the automatic locking mechanism, embedded in the new Trelock design.  Brand new Models such as the U4 Mini, U4, U4 Flex, U5 or the U5 Mini Flex complete the series. The Flex models offer an additional loop cable with a length of 120 cm and a cable diameter of 10 mm – locking to stationary objects is now even more flexible. The disc style cylinders used in the newly added models offer special protection against breaking or drilling attempts and thus perfectly complement the IN-X® cylinders of the proven models U6 L, U6 and U4 Plus. The new range offers even more variety and excellent quality in addition to the already familiar and proven functions such as dust protection cap, corrosion protection and reversible key. The shackles are made of hardened steel and have a soft surface to prevent scratching of your bicycle frame. All models come with the universal mounting bracket ZB 401.
