This is a bicycle shop in the garage of a house in a small residential neighborhood. It even has a very small sign: "bike shop". The owner/operator is named Peter and I recommend him to you because: (1) he doesn't make fun of you if you don't know anything about bikes, (2) his prices are reasonable, (3) he works quickly, and (4) he is very nice. He will even attempt to repair Walmart/Toys R Us style awful bikes although some bike shops around here will not touch them.
The shop mostly does repairs but there are a few bikes for sale as well. Cash or check only. I called ahead, he said come right over. I left the bike in the late afternoon on a Friday and picked it up on Saturday morning. He did a great job.
