I am a recent Halfbiker but I am now pretty confident to ride various terrains, including parks, trails, parking lots, schools, shopping centers, church lots, and just street sidewalks.
Atlanta is very hilly and has very few open areas but riding in parks and bike trails is great.
I usually stop if I hear people say something when I ride past them or if they look interested. I get off the bike and tell them what it is, where I got it, how it rides and how much FUN and FITNESS I get out of my rides.
People usually get their mobile phone cameras out and snap pictures of me and my Halfbike.
I am a 55yo guy but I love my Halfbike, I am confident and good on it now, and I get so happy thinking about riding, then riding it, then relaxing after a great ride.
