Lance Armstrong asks Aucklanders for a ride
Brown acknowledged Armstrong had severely damaged cycling's credibility and hurt a lot of people but felt he still deserved support.
"I watched him for 10 years competing in the Tour de France and it was quite incredible to ride with him," Brown told Newstalk ZB's Tony Veitch.
"I'd never met him before so it was pretty special.
"My little boy's getting into cycling and triathlon now so I took him along and Lance was great.
"It was pretty cool."

But since making those statements, Brown has been attacked on various social media channels.
He withdrew from a planned interview with Newstalk ZB's Mike Hosking this morning.
Mike Hosking: Nothing wrong with Cameron Brown riding with Armstrong
Hosking blasted the trolls that had lashed Brown on social media.
"He doesn't want to talk to us now because he has been trolled on social media," Hosking told his listeners. "Why we need to go around attacking people for things they do like this is beyond me."
Brown told Veitch he recognised the damage Armstrong had caused.
"I don't condone what Armstrong did," Brown told Veitch.
"I think it was a part of the era of what they did in cycling and you'd hope that they've cleaned it up by now but I'm still sure there's drugs out there in that sport.
"Everyone did it in that sport but he probably regrets how he went about it and what he did to some people and he's maybe going around the world to try and apologise to a lot of them.
"I think he's probably just trying to forget about the past and move on. And hopefully people can forgive him but probably there's a lot of people that can't."
