I think (some of) the Citibikes are wobbly and slow because of (some of) the riders on them. I've found the bikes plenty fast enough for the congestion they are ridden in, and they are as stable as you'd expect from 40 lb of bike on big tires. I really enjoy riding them. Just was a bit chagrined at the empty stations.
So there definitely continue to be rebalancing issues. The other morning the dock by Atlantic Terminal in Brooklyn was empty but for a lone bike with flat. That same afternoon the dock at 31st and 8th was full. No problem, hit up the one on 33rd and 8th where much to my surprise it was missing entirely! Had to run back downtown to 29th and 9th to dock the bike and hustle back to Penn on foot to catch my train.
As far as wobbly - I guess if you are going slow. I find that I can get them going pretty good - especially coming down off the Brooklyn Bridge
