Why this product
Why the Thule Motion 3 XL?
The Motion 3 XL delivers 18 cu ft at 44 lbs — lighter than the Black Glossy version and right in the premium sweet spot. Dual-side opening and PowerClick mount make solo loading manageable. The downside? At 165 lb capacity, you get the same weight limit as the smaller L, and you're paying premium pricing for what is essentially mid-range capacity.
