Welcome to Internafre Inc. We introduce exclusively the Cycle-Cuff family of bicycle locks, The Cycle-Cuff T-50 and The Cycle-Cuff T-100 are the most convenient, especially for those quick stops when using a typical lock takes longer than the stop itself. Excellent deterrent against opportunity theft. Most young bicycle owners don't want to hassle with locking their bikes. Cycle-Cuff makes it easy and fun! Excellent as a primary and secondary bicycle security device.
