How to choose 選購指南

Which numbers decide whether you like riding it, which are marketing, and what to check before you buy.

This is the page every model review links up into, so it is the one that has to make the argument properly. Ninety reviews each restating how a hub motor works is ninety thin pages; one page making the case, linked from ninety, is a page that ranks.

Range is the number most often wrong

Quoted range is measured at a light rider weight, on flat ground, in eco mode, at a temperature nobody commutes in. Two thirds of the claim is a reasonable planning figure for most adults, and half of it is the honest one in winter.

Brakes matter more than watts

Every model on this site is filed with its braking system in a comparable field, so the question can be asked across the whole catalogue rather than one review at a time.
