Besides my usual bike commute to work, I put in nearly two hours today taking residents for rides on this. It's a duet bike, made in Holland. The chair disconnects from the rear cycle part so I can pick up and deiver residents right from their rooms. 7sp Nexus IGH. For short rides I go around our courtyard (it's pretty big), long rides along various pathways around the facility (11acres) and longer still rides to and around a nearby lake.
