The first bike is the reference for the sign of each difference. Green and red are used only where the direction is meaningful: lower weight and higher published electric motor output. Dimensions, travel, capacity, crank length and price are differences without an automatic verdict. “—” means the manufacturer has not published the value. We show weights in kilograms; the manufacturer’s values in pounds are not displayed.
