Takeaway app Deliveroo has sought a meeting with the Gardai after a spate of attack on its workers in Dublin.
The riders claimed that they are regularly threatened with knives while making deliveries around the city centre.
Deliveroo rider Lucas, from Sao Paulo, said: "We are facing too many attacks from teenagers.
"They try stealing our bicycle and hit you with some things and we don't know why it happens because we are just working."
He told RTE's Today with Claire Byrne: "Three weeks ago I was delivering in Dublin 8 and 15-20 guys tried to stop my bike.
"I was very, very, very nervous. I could escape but I have some friends and they couldn't and they lost their bikes."
The cyclists have had everything from rocks, eggs to bottles and fireworks thrown at them.
Gardai have implemented an enhanced stop and search regime to tackle increasing knife crime in the north inner city.
The new policing tactics have seen a team of gardai who have been tasked with finding dangerous weapons being carried in the area.
It comes as there have been at least six stabbings in the locale over the last two weeks.
