How to make an e-scooter faster? Electric scooters have become essential urban mobility solutions across Western markets. According to 2025 research by the European Micro-Mobility Transportation Association (EMTA), approximately 42% of e-scooter users express dissatisfaction with stock speeds, with 68% seeking performance improvements within legal limits. Data from specialist platform novascooter reveals mainstream e-scooters average 25km/h, while legal modifications can achieve 35-40km/h.
Speed optimization relies on three interconnected systems: the electrical system (battery and motor), control system (ECU and governor), and mechanical system (tires and drivetrain). Cambridge University Engineering Lab’s 2025 tests demonstrate that synchronizing these systems can boost efficiency by 23% while maintaining over 85% of factory safety margins. Notably, EU regulations cap civilian e-scooters at 25km/h (some nations permit certified 30km/h models), while U.S. state laws vary between 20mph and 30mph.
