As per the seller, these bikes have been sitting in a warehouse for a few years. I suspect, when all is said and done, they'll be sitting for a few more years. Seller doesn't seem ready to face the market and I predict a longgggg, slowwww, Dutch auction.
1. bike sizes aren't ideal.
2. You are at a disadvantage if you're selling something you don't know much about. You don't get fair offers with lazy ads like that. Most of the bikes aren't photo'd and have descriptions like "Shimano crank".
3. The number of people who can store and ship this number of bikes is limited.
