Hemmings Find of the Day – custom trike

Published in

Words do not really suffice for this custom trike for sale on Fortunately, there’s a video and plenty of photos of it from CAD drawings through the build process and all the way to the show floor, illustrating just what went into it. From the seller’s description:

Personal project of a Mechanical Engineer with two US patents. Goal was technical correctness with no limits on time or money. Although never intended to be a show vehicle, innovation and attention to detail have brought recognition and awards in national shows.
