  • Bronze – Bronze rated bike locks can only withstand attacks carried out using basic tools. As such, they are only ideal for the low-risk areas or cheaper bikes.
  • Gold – These are most secure lightweight bike locks available today. They can withstand vandalism attempts carried out using a complete set of tools.
