This is a set of three wire locks that were used for bicycles. All items show signs of use. Each lock is 180 cm long. ① TIOGA brand, includes one key. Used with a holder fixed to the seat post. ② TRELOCK brand, includes two keys. SK740, 10mm diameter. The plastic bracket for fixing to the bike frame is damaged. I used zip ties to attach it to the bike. The other bracket is for fixing to the bike with screws. ③ Unknown manufacturer, includes one key. The wire is thin, making it easy to handle, and I found it to be a user-friendly product.
