The Beechboro resident has developed a large following and become a local hero after gifting about 100 bikes on the Pay it Forward Perth Facebook page.
The 42-year-old said he discovered the page and came to the realisation that �stuff was just stuff� and that he loved the feeling of giving.
�The more I gave, the better I felt and it is only worth what you pay for it; the goodwill it creates when you give it away is priceless,� Mr Devereux said.
Mr Devereux said he tried to give away two bikes a day, adding he was inspired by God to do so.
�They come from all over,� he said. �There are many people who want to help me in this strange endeavour.
�They let me know where bikes can be collected, bring me spare parts and one lady brought me a gift card for a hardware chain so I can use it to buy bike spares and so on.
�I can�t turn over enough bikes for everyone who needs one, but it is great to be able to go up to a stranger on foot and say �here�s a bike for you mate�.
Mr Devereux said through the help of his church, he hoped to get enough bikes for people in developing countries including Cambodia and Uganda.
