Two Wheels One Planet, which has shops in Costa Mesa and Lake Forest and is rooted in a company that has been serving Orange County cyclists since 1959, represents the best of both sales and repair worlds. The inventory is massive, but so are the choices in types of bikes and range of prices. You can go in, say, for a beach cruiser you don't want to spend more than a couple of hundred dollars for, and a knowledgeable staffer will shuffle you over to the rows of bikes fitting your needs. By the way, Two Wheels One Planet hires actual riders. You see their bikes in the racks outside (also, thankfully, freeing up more parking spaces for cars). Tell them you want the best, and they'll gladly point them out. You won't be upsold or downsold, and whatever you buy, the staff will encourage you to bring it back in a few months for a free tune-up and to make sure everything's hunky-dory.
