• Use lock-specific lubricants when lubricating any bike lock.

COMMON QUESTIONS

• Can I lock bike frame and a wheel to a bike rack? Yes, in most cases, but not all. The shackle shape is compact and optimized for locking bike frame to bike rack. The mini shape is well suited for the Sheldon Brown method of locking rear wheel through rear triangle to bike rack as shown above.
• Can I lock an e-bike to a bike rack with a TiGr BLUE mini? Yes, in most cases.
• Can I lock a Onewheel electric skateboard or an e-scooter with a TiGr mini? Yes, in most cases it will work for bicycles, e-bikes, Super73 bikes, Onewheel riders and more. 
• What if my bike frame does not have bottle cage mounts? The TiGr mounting clip works with most bottle cage adapters. It also fits easily in most frame bags, backpacks and bicycle panniers.
• Are bottle cage screws included? No, Most bikes come with bottle cage screws on board.  If not, standard M5 screws work in most cases.
• Will the lock scratch my bike? The clear plastic coating on the shackle provides frame protection.
• How secure are TiGr BLUE locks? Please see the lock testing page for information on lock testing.
