The business trailer housed all of Hector Garcia's tools and equipment.
Garcia said a neighbor called to inform him that his trailer was caught on surveillance video.
"I've had that trailer for about 10 years," he said.
Earlier Sunday, The Byke Shop held a fundraiser at Will Leather Goods on Heights Boulevard in Houston.
Garcia added that the trailer was used to give free bike repairs for children in low-income areas.
A GoFundMe account has been set up to help Garcia.
