Evidence & methodology
What we know, and what we do not.
A 0 to 10 weighted research model using normalized manufacturer specifications and documented evidence. Portability (30%), capacity (20%), build and warranty (25%), organization (10%), and value (15%) are scored independently. Manufacturer claims remain labelled as claims, price judgments are time-stamped, and no hands-on durability or wheel-performance claim is made without physical testing.
