Check out this brand new Li-Ion folding bike from IZIP:
This is a new 2009 model that should be available within the next week. IZIP also makes a lower cost SLA folding ebike here:
If you're looking for a low cost option, the Via Mezza (formerly EzGo) is very popular. But it's heavier than their newer model and the battery will last about 1/3 the time. Plus, it doesn't have gears like the upper end model - only one speed.
