Osaka police arrested two men on July 31 for illegally converting electric-assist bicycles into throttle-equipped electric mopeds [1].
These modifications are significant because they transform bicycles into motorized vehicles that require a driver's license to operate legally. By adding throttles, the bikes can achieve higher speeds than standard electric-assist models, creating potential safety hazards on public roads.
Reports said the suspects modified the bicycles to operate as mopeds [2]. Under Japanese road-traffic law, vehicles equipped with throttles that propel the bike without pedal assistance are classified differently than standard e-bikes [2]. This classification means the operators must possess a valid license, and adhere to specific registration and insurance requirements.
Some reports said the arrested individuals were Vietnamese [2]. Other sources did not specify the nationality of the two men [1].
Police in Osaka have targeted these conversions to curb the rise of unlicensed motorized vehicles in urban areas. The operation focused on the illegal sale and modification of these bikes, which often bypass safety regulations designed to protect pedestrians and other cyclists.
The two men [1] now face charges related to the violation of road-traffic laws. Authorities continue to monitor the sale of conversion kits that allow users to bypass the pedal-assist limits mandated by national safety standards.

This crackdown highlights the growing tension between the popularity of micromobility and strict Japanese regulatory frameworks. As the market for e-bike conversion kits grows, authorities are increasingly viewing these modifications not as simple upgrades, but as serious legal violations that circumvent licensing and safety protocols.
