I recently bought a bike from them. They did a great job. At that point, I was using an old department store Schwinn from when I was only a teenager.
The sales lady helped me out. She went through my options and helped find a bike that fit me well. She also indicated which accessories are useful versus a waste of money.
I do understand locks and security. I like that Thick is explicit regarding why they don't carry cable locks. It indicates to me that Thick is trying to help the customer and not waste our time.
