We compared two ab wheel rollers with a knee mat included: the Amonax Convertible Ab Wheel Roller and the ROMIX Ab Roller.
What we looked at
Wheel setup, stated width and load capacity, knee mat, assembly, and price.
The verdict
If you want a convertible roller that can be used as a double wheel for stability or switched to a single wheel for a harder core workout, the Amonax is the more adaptable pick, at £11.99. If you would rather pay £2.00 less for a single, 3-inch-wide wheel rated to a stated 200kg with a thicker knee mat, the ROMIX is the value option, at £9.99.

A £11.99 roller that converts between double-wheel and single-wheel settings.

A £9.99 single-wheel roller rated to a stated 200kg with a thick knee mat.
