I also saw the Ebay listing. Those prices are too good to be true. But I did register with the escrow company they noted and I have exchanged a couple of emails. I'll buy the bike If they turn out to be legit. Only gave my address and name. No financial info.
I couldn't find them on the business listing for Helena either. Map quest did indicate the address but that doesn't mean anything.
I think I will attempt to locate a business near their address and ask them if the bike shop exists.
