Beijing strictly investigates illegal modification of electric bicycles, considering mandatory helmet-wearing.

As the summer approaches, the number of non-motorized vehicle riding activities has significantly increased. In order to further regulate the traffic order of non-motorized vehicles and improve the level of civilized urban transportation, the Beijing Public Security Traffic Management Department, together with the Municipal Civilization Office and other departments, recently launched a special operation to rectify uncivilized behavior of non-motorized vehicles throughout the city. Police on the scene told reporters that for electric bicycles illegally equipped with lights that affect traffic safety, Beijing traffic management authorities will strengthen on-site enforcement. For the first discovery of illegal vehicles, warnings and penalties will be issued to riders, and they will be required to remove the additional lights or restore them to the original factory standards. If the vehicle is found to be illegally modified again, the vehicle will be confiscated according to the law, and a fine of 500 to 1000 yuan will be imposed for the illegal act of driving a modified electric bicycle on the road. Any clues of commercial modification will be promptly transferred to the market supervision and other departments for handling.
