Very nice, practical upgrade to my Greaser, I believe the construction is aluminum and the deck is bamboo. Michael Blast added the integrated tail/brake light upgrade for me which gives me extra peace of mind when riding in traffic. Holds a couple of canvas saddlebags nicely. Only ding is that the paint is rather fragile and has shown a few chips already, not a problem for me but if you are looking to keep your bike museum quality you might want to treat it with extra care.
