I don't know if this is in fact the same as the Schwinn Izip or what. I saw one in wal-mart last weekend and liked how it had an optional second battery spot, and up to 40mile range with both batteries.

I might get one for those days I am not up to riding but must to get around. And maybe my dad will get back into riding with an easier method.
