Most of those reviews are satirical, as are the Q&As. The product is a grotesque parody of a bicycle, so some scallywags have reviewed it appropriately.
It has clearly been designed by someone who has seen a few photos of fast road bikes, but doesn't know or care about any aspect of what makes a bike fast. It's the bicycle equivalent of a cheap Honda that some teenager has absolutely ruined with tacky "upgrades". It might not be obviously apparent to a novice, but the product images genuinely made me laugh out loud.
The reviews are an embarrassment to Amazon, but so is the fact that this product is even for sale. It's an atrocious bicycle that should have never been built in the first place, designed with the sole intention of deceiving naive customers. A quick browse of the bicycles category on Amazon suggests that this is an endemic problem - the customer reviews suggest that many are dangerously defective.
