I haven't encountered any continuos geared bikes yet. Just the old and new models. Usually easier to find the older style. Must be a lot more of them in service. Trying to find a bike to get to work at 3:45am yesterday and there were none convenient to home. on the tripp home at 10am, most Times Square racks were empty, save one in Rock Center that had 39 bikes. Bike distribution is still the big problem.
