Everyone knows they're just doing their job, but we usually can't help but get annoyed every time a store attendant comes up to us and asks, "Can I help you? can I?" Sometimes we don't want to be disturbed; That we want to see some things for ourselves. But when it comes to the attendants of bike shops that "pester" you are often a welcome gesture; Especially if we don't know what kind of bike we are looking for.
Bike shops must meet certain requirements that make them a quality establishment. If you think that it is only about selling the most expensive and well-known brands of bikes, then you are wrong. With bikes, it's all about personal preference. While anyone can ride and be addicted to one type of bike, there is always one that is right for you. And the bike store should be able to help you find it. You can also visit godspeed-bikes.de/bikes to find a single-speed bike shop.
A good bike store should offer bikes in a wide range of sizes and types. They should sell at least a few variants of the most basic types: road, mountain, single speed, fixed gear, and whatnot. The more they have to offer, the more likely you are to find what you need.
You can't feel how well the bike handles until you test it. If you're in a brick-and-mortar bike store, feel free to ask if you can take it for a spin. Most of the time, they won't allow you, but good stores will at least let you ride it steady so you can get the feel of it.
Lastly, good stores have attendants who can't force a bike on you. Sometimes, they will feel pressured for their sales figures, commissions, and so on and try to get you a bike that you don't even want. As mentioned above, the right bike for you is the one you want to ride. For example, if you're set on a fixie, don't allow them to talk to you because they hate fixies.
