POST FALLS — All 6-year-old Jack Hagenbarth wanted to do on a sunny Sunday was pick up trash.

While he was accomplishing his goal of clearing garbage from the green space in the Greensferry Landing neighborhood in Post Falls, his bicycle was stolen.

"We left the bike. We were walking less than five minutes and we got back and the bike was gone," his mom, Ann Hagenbarth, said Monday. "We were less than five minutes away from it. It was crazy."

The Hayden Canyon Charter first-grader had asked his mom if they could collect the trash he'd noticed in the area rather than go for a hike that day. He rode his bike to the space, set it down for a few minutes as he filled his bags and would grab it before clearing the next stretch.

"There was so much garbage," Hagenbarth said. "He just put his bike in the grass; it wasn’t by the road or anything. He’d go get his bike and bring it closer to us."

When he returned to it after just a few minutes, it was gone.

"We just kept looking," Hagenbarth said. "I said, 'I think your bike was stolen.' He was just like, 'I think so too. It's OK. It's not the best bike.'"

Even after it went missing, the bike wasn't the first thing on his mind.

"He said, 'Well, at least we got a lot of garbage,'" Hagenbarth said. "He had a really good attitude about it."

They walked home with their bags of trash. Jack's mom took his picture and told him how proud of him she was, then she went to social media to share what had happened.

The support for this altruistic little guy immediately poured into the comments section.

"Jack needs to know that his kind heart is seen by good people in the world," one user wrote. "Do not let the world's ugly make you ugly, keep seeing the good in the world. I would love to send a donation towards a new bike."

"What a great deed to end in a bad way. I’m sorry," another user wrote.

Hagenbarth said she was "blown away" by the amount of kindness shown by everyone.

"I had people private message me and when they saw my Venmo they just sent me money," she said. "I got him a great bike and I'm going to get him a helmet and a lock."

She said honestly, Jack was growing out of his old bike and it was about time for another one.

"I’m a single mom. I never would have bought him a brand new bike that is $200," she said. "I’m really happy to get him this brand new bike."

She said kids leave toys in the neighborhood park all the time.

"I just hope parents can teach their kids that just because something is left in the park, it's not just a free for all," she said. "If your kid comes home with something that isn't theirs, bring it back."

She said she's pretty sure it was a child, not an adult, who grabbed Jack's bike. It was just one of those unfortunate things, she said.

"I hope that person needed a bike," she said. "Maybe they don't have parents who would give them a bike. Maybe they can fix it up."
