But 90 lbs vs. 56 makes me wonder, where did they hide that much ballast to get to 90 lbs on an aluminum bike?
I don't think very much of that bike is made of aluminum. You will notice that they also make a similair model with an "AL" designation in the model number CBAL24V450 which they say is 80 lbs. It may contain more aluminum but is still a heavy bike.
I personally considered buying the large bike but opted for the aluminum folding bike (equivalent to the Currie IZIP EZGO). Even taking the size into account the folder is very much lighter. It probably weighs as much as it's battery.
