My wife's in the market for a new bike. She's had a large beach cruiser that she loved, but was way too heavy for her to lift on to bus and train racks.

Her big requirements are a step-through frame, an internal geared hub (features of the old cruiser), but light enough to pick up easily.

We've looked at some stuff online, like the Breezer Town bikes, the Fisher Simple City, and the Trek Belleville WSD.

Does anyone know if one of these would be lighter than the others? Are there other models we should look at?
