Massachusetts lawmakers are considering a comprehensive micromobility regulatory overhaul, proposing a four-tier speed classification system based on speed. The bill, S.3077, would categorize everything from bicycles and e-bikes to electric scooters and Sur Ron-style electric motos. It includes a “Maximum Designed Speed Tier Classification System” which categorizes micromobile devices based on their top designed speed. Each tier will have different access rights and regulatory treatment, with Tier 0 devices largely treated like bicycles, while Tier 2 and Tier 3 would now include many of the grey-area or previously illegal micremobility devices like Sur Ron and Talaria-style motorbikes. The proposal also includes a ban on aftermarket modifications that increase the speed of de-restricted e-bike and moped vehicles.
