The three major food delivery companies in Singapore said they have measures in place to ensure their riders use PMDs that are certified safe.
Shops are offering steep discounts on devices ahead of next month's deadline for devices to comply with new fire safety standards.
Motorised personal mobility devices such as e-scooters may soon have to conform to a safety standard, given the fire and electrical hazards they can pose.
The stiffer penalties for PMD users caught riding on roads is a timely move but Singapore needs to step up public education and tighten regulations.
Spring Singapore and the Land Transport Authority will be reviewing the product safety requirements of personal mobility devices such as e-scooters.
When the new law goes into force later this year, bicycles and PMDs such as e-scooters, can travel on public paths, together with pedestrians.
According to local distributors, most mobility scooters are designed to be safe and stable medical devices for the elderly and people with disabilities.
Bicycles and personal mobility devices may be recommended to be allowed on footpaths, but the code of conduct proposed also contains rules such as speed limits.
