"We needed some room and the principal gave her go-ahead and the groundsman found us some storage space.
"One of our mums put a call out on social media for donations of old bicycles that we could rebuild, " he said.
Joe and a small group of students work after school hours, mostly on Tuesdays and Thursdays, to recycle all sorts of discarded bicycles from once thoroughbred racing types to little pee-wee bikes for three and four year olds.
That was late last year and now the storage sheds are bulging with completed examples and projects awaiting attention.
There is almost no cost.The group has one set of specialist bicycle tools, but most just need a clean-up, get the brakes working, oil here and there and the tyres pumped up.
Where parts are needed damaged examples are cannibalised and they're away again. Joe has got to know the local bike shops, and now and then he'll put his hand in his pocket to buy a few things like inner-tubes when the originals are past-it.
Joe and his group of after-school bicycle mechanics have rebuilt about 56 bicycles which have been given away to kids who need them often through schools and to the migrant community.
"Many families have a few old bicycles sitting around rusting away.
"I just like to see kids cycling to school. There's not enough people cycling. It's better for the environment and everyone."
