Piggy Back Bike

A great day for a bike ride today and I discovered a most unusual bicycle "pick-up truck" along the way.
PeaceHealth Rides is a bike share rental business that allows one to rent a bike and, for a small extra fee, leave it anywhere in the downtown city area  of Eugene rather than at a "hub".
I wondered who and how the randomly parked bikes were collected. Today I learned about the "Radburro" electric bike used to haul bikes back from the bike paths where no vehicles are allowed to trespass.
A maximally cool and unusual tricycle for sure.
