Yow, this is remarkable.
Wife and I bought two of the XP2.0st bikes 18 months ago for the special deal price of $999, including a similar bundle. Great machines, and the bundle adds a lot of value.
We've since added ( in order of importance):
(1) 11-34 freewheel ($20)
(2) Wireless horn + alarm ($25)
(3) Folding steel basket for carrying groceries home ($30)
(4) FlatOut tire goop ($30)
(5) Water bottle carrier ($20)
(6) 5v USB charging port ($15)
