Plotting an NYC Brompton. Advice needed.
I'm planning on buying one to make my NJ Transit-to-Midtown commute more palatable. Planning on a titanium model with a straight bar and fenders, no rack. I'll be schlepping it through Penn Station every day.
My main question is about the drivetrain -- three-speed? two speed? Single? Factors to consider are that 1.) I like to ride fast. 2.) I live on a short but Matterhorn-like hill in New Jersey, the only significant climb on the route. 3.) I'm trying to keep the weight down because of the aforementioned Penn schlep.
Advice from any and all quarters is welcome.
