Consumer Reports is (and has been for at least 50 years) the monthly hard-copy publication of Consumer's Union. For the last 15 or 20 years, they also sell on-line access. They take absolutely no advertising revenue, and they subsist on subscriptions and donations. They have litigated hundreds of pro-consumer lawsuits, including the famous Bose vs. Consumer Reports, where the infamous sleazy speaker manufacturer sued them for libel.
You can purchase as little as one-month access. It goes to a good cause.
I would never buy a car or a large costly household appliance without consulting their reviews. I never thought about bicycles, but it is probably a good idea.
