For the past few years, up to 10 kids aged between five and 13, have built anything from tree houses and flying foxes - all to be destroyed by Wagga City Council (WWCC).

The kids turned to designing and building their own bike jumps in the median strip of a Turvey Park Street about a year ago, sourcing the materials themselves and using dirt from their parents' yards.

In a world where most other kids would prefer to stay inside playing video games, this group's idea of harmless fun doesn't sit well with WWCC - it has destroyed a cubby house and two flying foxes in the past three years.

Last Tuesday, council demolished the bike jumps with a front end loader while the boys were at school with no explanation as to why.

That afternoon, the boys were back on the street remaking the jumps.

"They rebuilt it that day," one mother, who wished to remain anonymous, said.

"There were eight of them out there with their shovels and the big ones were helping the little ones.

"It's a sense of community."

No complaints had been lodged by neighbours.

"They probably have good reason, it's just not being communicated to us," the mother said.

"If they let the boys know this is why they're doing it."

The mother said the boys had all been taught the road rules and there was a strong sense of comaraderie between them.

A WWCC spokesman said the area of land being used was a council-owned road reserve located between two lanes of traffic.

"The issue with constructing objects on this land is that council could be held liable for any injuries that may occur," he said.

"There are a number of playgrounds and recreation places close by that could be used as an alternative play areas, including the Botanic Gardens and Sunshine Avenue Park."
