Gardai have issued 547 fines to cyclists since new legislation came into force on August 1.
Breaking a red light was the worst offence, with 323 fixed-penalty charges of €40 issued.
Fines can be issued on the spot without the need for a court appearance. Cyclists caught committing one of the seven offences are asked to provide their address and are sent the charge in the post. If the cyclist fails to do so, gardai can seize the bike.
The figures provided to the Herald by gardai reveal that after breaking a red light, the next most common offence is having no front lamp or rear lamp lit during lighting-up hours, with 110 fixed charge notices being issued.
After this there were 67 fines issued for cycling without reasonable consideration and 31 fines for cycling in a pedestrianised area.
"An Garda Siochana would appeal to cyclists to adhere to rules of roads and for motorists to respect cycle lanes," a garda spokesman told the Herald.
Since last August, there have been 15 fines issued for cyclists going through a red light and one for fixed notice applied for a cyclist going beyond a stop line when the red light has been flashing.
No cyclist has been fined for failing to stop for a school warden sign.
Figures for the amount of individual cyclists who have been fined were unavailable.
Cyclists are given 26 days to pay the fine and if they comply the matter will go no further.
Failure to pay within that period will result in the fine increasing by 50pc to €60, with a 56-day window to pay.
The fixed-charge notices follow Road Safety Authority (RSA) and garda consultations last year and in 2014. A set fine of €40 was introduced for seven of 36 traffic offences.
Figures released by the RSA show 75 drivers, 27 passengers, 32 pedestrians, 22 motorcyclists and nine cyclists lost their lives on the roads last year, a decrease of 15pc on the previous year.
Figures for injuries to cyclists reached a 10-year high of 630 in 2012, the most recent year for which the RSA has complete data. This was up 59pc on 2011.
