"The lure back was in essence because of mountain biking and what it provides. The social aspect, the adrenalin, the adventure, the sheer fun and freedom it provides," he said.

"We have a world class mountain bike facility right here on the city fringe.
"The Redwoods has over 150km of purpose built mountain bike trails. It is literally world class. The most incredible thing about it is it costs the public not even one single cent to use it."
Mr Alexander said people might be intimidated to try the sport.
"The common comment is 'mountain biking - those guys are nutters', well yes, we are, but it doesn't have to be all out jumps, back flips and carnage crashes like we see on the TV."
Mr Alexander said he wanted to get people out of their houses, on to bikes and into the forest, in a safe, controlled manner.

Classes will be limited to the first 20 people who register via email. Children under 14 must be accompanied by an adult.
