They just brought in a new model bike on Citibike. I heard but haven't confirmed that the original maker is now out of business. The new model has Sturmey Archer hubs. The whole bike is much improved in my view, and the S-A equipment is part of that. The brakes require less effort. The gearing is taller. The rear hub ticks in that old familiar way. The whole bike feels lighter, and I can't explain why. Geometry? There aren't many new models on the streets yet.
