I would argue that google is being used incorrectly here. Google is specially being asked for a product list which meets a certain criteria. The user is asking Google to recommend the best bikes..

The user is actually looking for authoritative bicycle reviews to make a purchasing decision. Searching for “bicycle reviews” would give a far higher chance of finding what the user is after. They can then use the criteria on the review site to narrow down what they are after.

There is also a limit to what searching will get you. Going to a bike shop will allow an expert in this subject matter to assess your personal requirements and advise accordingly. For a lot of things, going out and talking to someone will yield far better results than Google ever will.
