LTA said this was why it developed a portable device that could detect illegal modifications by testing an AMD\u2019s top speed even while it is stationary.<\/p>\n
Since it was first deployed in November 2025, the devices have contributed to the detection of more than 100 offences and the impoundment of 30 non-compliant devices, it added.<\/p>\n
About 20 per cent of these impounded devices could have evaded detection if the speed measurement devices had not been used.<\/p>\n
In 2025, LTA seized around 900 non-compliant AMDs and detected about 900 offences relating to them.<\/p>\n
Those convicted of using non-compliant AMDs may be fined up to S$10,000 (US$7,886) or jailed up to six months or both. Repeat offenders can be fined a maximum of S$20,000 or jailed up to 12 months or both.<\/p>\n
PMDs and power-assisted bicycles must also comply with UL2272 and EN15194 safety standards respectively, with LTA noting that there were 49 fires involving AMDs last year.<\/p>\n
“Common illegal AMD modifications include replacing electrical parts such as the battery and motor hub with third-party or non-original components.” it said. “Such changes would void the device\u2019s safety certification and significantly increase the risk of fire.”<\/p>\n
LTA added that there were around 90 offences involving retailers in 2025, warning that “such alterations put both device users and the public at risk”.<\/p>\n<\/div>\n
