Cyclists face on-the-spot fines of at least €50 for breaking red lights and other dangerous habits under new rules.
The regulations, which could be in place by the end of the summer, will see offences being targeted by Gardai anxious to clamp down on so-called lycra louts.
Under the present laws, a Garda can stop a cyclist, take their name and details and threaten them with a district court appearance if they break the rules of the road.
In extreme cases they can impound the bicycle.
