If you live or work in Burlington, you’ve no doubt noticed an uptick in businesses making deliveries — and sometimes statements — with bicycle-pulled trailers. August First, for instance, uses one to haul loaves from its South Champlain Street bakery-café to the company’s new sandwich shop, Stacks, on North Winooski Avenue.

At the Artist Market in City Hall Park on Saturdays, you can see bike trailers turned into mini retail shops: Aaron Stein of Revival Studio — aka the guy who makes cool art, bracelets and other objets from old license plates — has one such handsome market trailer, which he designed. Aptly, Bike Recycle Vermont has another, from which the small company sells jewelry and belts made from, yes, bicycle parts. At the adjacent farmers market, vendor Narwhal Pickles operates out of yet another portable shop on wheels.

This week, at the First Friday Art Walk, these three, and up to a dozen other two-wheeler aficionados, will celebrate at an event aptly called “Bicycles at Work” at the Pine Street Studios in Burlington. In the community studios’ tradition of throwing a party upon completion of a project, says Stein, “Local businesses who use bike trailers and cargo bikes will set up to show off their rigs and sell product.”

And, speaking of product, Stein notes that he takes design and building commissions, and that studio manager John Marius is thinking about giving bike-trailer workshops. The trailers start with a standard platform but are then customized according to individual needs, Stein says. “The ones I’d like to be involved with are designed,” he emphasizes.

“Bicycles at Work” Friday, June 1, 5-8 p.m. at the Pine Street Studios in Burlington. revivalstudio.com
