Edinburgh is fortunate to have a range of shops. Try a few, ask for advice, choose one you feel comfortable with.
As Jacquie Phelan says "1 Choosing a Shop - walk into store, making a mental note of your sense of height in inches when you go in. Wait for service, observe the reception you get, talk (if you can get the fellow's attention), then take note of your stature upon leaving the store. If you feel appreciably smaller, do not return. Find another bike shop, and hope for a real human connection, a salesperson interested in what you want to do on your new bike, how you intend to use it."
Edinburgh shops with web sites Alpine Bikes, BG Cycles & Blades, Bicycle Repair Man, Bicycleworks, Biketrax, Eastside Bikes (secondhand), EdinburghBicycle, Leith Cycle Co, Macdonald Cycles, The Bike Chain, The Triathlon Centre, Velo Ecosse.
Bikes are also sold in Supermarkets and DIY stores. Often pretty cheap - you get what you pay for, but will they be able to help if you have a problem?
If you want a second-hand bike with a 3 month guarantee try The Bike Station.
Gumtree can be a good source of local bargains, but - buyer beware...
