AlterLock Teams Up with Bike Index to Support Cyclists and Deter Bike Theft in the U.S.
Introduction
Bicycle theft continues to be a significant concern for cyclists, particularly in urban areas where traditional locks often fail to provide adequate protection.

About AlterLock
AlterLock’s smart anti-theft alarm and GPS tracking device pairs with a mobile app to provide multi-layered protection. When motion is detected, the device triggers a loud alarm and sends an instant notification to the user’s phone via the LTE-M network. If the bike is stolen, AlterLock continues tracking its location via GPS to aid in recovery.
After earning strong support from Japan’s cycling and motorcycle communities, AlterLock is expanding globally with its third-generation device, reinforcing its mission to let riders move freely and confidently — without fear of theft.
Comments from the Teams
“Protecting your bike shouldn’t stop at a lock. We’re excited to support Bike Index and their commitment to community-based recovery and cyclist empowerment,” said a spokesperson from AlterLock.
By offering this discount, AlterLock aims to empower more cyclists with smart security tools — and to support platforms like Bike Index that make cycling safer through collaboration and openness.
