With the grandparents watching Nate, K & I went down to the beach. After walking along the beach, we stopped in Old Orchard for a bite to eat. Parked at the side of the plaza was the “Conference Bike“*. Neither of us had seen such a thing and it is both a thing of creative beauty and a pretty cool mechanical gadget.
The quadricycle (double wheels at the rear) is powered by all seven riders while one steers and operates the brake and bell. Each rider has a seat and pedals (and can grab on the the circular bar in the middle) which connect by chain to a common drive shaft. The drive shaft is connected using universal joints to form a single drive which operates a heavier chain to the rear wheels.
The front wheels are turned via a steering wheel and what looks to be a rack and pinion type steering setup. The bike was available for rental at $70/hour.
