How do we recognise unapproved motorised bicycles?

THE joint reply from the Land Transport Authority (LTA) and Singapore Police Force ("Only approved low-powered motorised bicycles allowed on roads"; Wednesday) stated that last year, about 1,250 errant cyclists were issued summonses for using unapproved motorised bicycles.

What happened to their bicycles? Were they confiscated and destroyed? Or were the owners allowed to modify their bicycles to meet the requirements?

Is it illegal to import high-powered motorised bicycles, or those that do not have the automatic cut-off function when the speed exceeds 25kmh? If so, how is it that so many of these are still being used on our roads?

Have dealers of such bicycles been prosecuted for importing and selling them in Singapore?

Since all approved models are affixed with an LTA seal before they are allowed on public roads, could the LTA publicise what this seal looks like, so that members of the public can lodge police reports when they come across motorised bicycles that do not carry the seal?
