About half of our cycle group. The fellow in the center with no helmet is one of two tour guides. This fellow rode a cycle in the lead position as we coasted downhill. The other guide drove the van and trailer (seen in the next photo) behind us.
The bikes we rode were really sort of weird. The tour folks call the "cruisers", apparently because this model is easier to cruise on. They have wide seats and high handle bars. The result is that the ride sits more upright in the saddle than on a mountain or road bike. The downside, though, is that pedalling is a real chore. Fortunately, only for about 100 yards or so did I have to ever pedal, along the entire 12 or so mile route. Also interesting about the bicycles are their brakes. Instead of traditional caliper or cantilever brakes, which use rubber shoes to squeeze the tire rim, these bikes have drum breaks mounted near the hub of each wheel. The drum brakes don't wear out nearly as fast as the traditional variety, which is very important on a tour that's mostly about riding the brakes down a mountain.
