The catch
Thule Motion 3 XL Low
A bike carrier has less neighboring space with the wider shell.
Side by side
Thule Motion 3 XL Low vs Thule Force 3 L Sport compared: Low fits longer skis and Sport saves bar space, though a tight hatch can rule out both
Quick verdict
Motion 3 XL Low is for skis longer than 175 cm and up to 200 cm, or for a tighter overhead route. Force 3 L Sport is for shorter gear, when a bike needs neighboring bar space or the hatch calls for a shorter box. Restricted hatch clearance together with 190 cm skis may rule out both.
Before you buy
Why, and what it costs you
Long skis and short hatch clearance may clash
Low’s 200 cm rating covers a 190 cm ski, and Sport’s 175 cm rating doesn’t. Suppose the same car measures only 51 inches by Thule’s hatch method. Low then misses its threshold and Sport clears its own. Neither box handles that combined trip unless the cargo plan or an approved rack position changes.
Where this comes from
Take a 190 cm ski and a 51-inch Thule front-clearance measurement. Compare each value on its own with both documented limits. Passing one check does not make up for failing the other.
The catch
Thule Force 3 L Sport
Skis longer than that are beyond the 175 cm ski rating.
Thule Motion 3 XL Low
- Why pick it
- The vehicle clears the longer box, and your skis are 190 cm.
- Keeping the installed height low counts for more than room beside the box.
- The catch
- A bike carrier has less neighboring space with the wider shell.
Thule Force 3 L Sport
- Why pick it
- A bike shares the roof, and your gear fits within the 175 cm ski limit.
- Your front clearance by Thule's method is 51 inches.
- The catch
- Skis longer than that are beyond the 175 cm ski rating.

What this page compares
Long skis against shared roof space is the tradeoff here, with hatch clearance, crossbar width and garage height each checked on their own.
Motion 3 XL Low is for skis longer than 175 cm and up to 200 cm, or for a tighter overhead route. Force 3 L Sport is for shorter gear, when a bike needs neighboring bar space or the hatch calls for a shorter box. Restricted hatch clearance together with 190 cm skis may rule out both.

Low only becomes a candidate once its wider footprint and its hatch requirement both pass.

Sharing a 50-inch usable bar span with a bicycle
Look at the real bike carrier and its clamps. Spare width beside the shell doesn’t by itself show that the fit is safe.

In practice
Differences you will notice
Long skis and short hatch clearance may clash
Low’s 200 cm rating covers a 190 cm ski, and Sport’s 175 cm rating doesn’t. Suppose the same car measures only 51 inches by Thule’s hatch method. Low then misses its threshold and Sport clears its own. Neither box handles that combined trip unless the cargo plan or an approved rack position changes.
How we worked this out
Take a 190 cm ski and a 51-inch Thule front-clearance measurement. Compare each value on its own with both documented limits. Passing one check does not make up for failing the other.
Set aside room for the bike before you go for the larger box
Assume a hypothetical 50-inch usable span. The shell widths leave 15 inches beside Low and 25.3 inches beside Sport. When a bicycle carrier is in the plan, that 10.3-inch gap can count for more than three extra cubic feet. Actual mounting clearance still comes down to clamps, feet and lid movement.
How we worked this out
50 - 35 = 15 inches. 50 - 24.7 = 25.3 inches. It is meant as a width screen. It does not approve any particular shared installation.
A narrow box may still not clear the garage
Put the crossbar tops at 70 inches. The stated above-bar heights then suggest 82 inches for Low and 86.7 inches for Sport, so an 84-inch opening is already lower than Sport’s estimate. Low still depends on a measurement once installed and a sensible clearance margin.
How we worked this out
Assumed: 70-inch bar-top height and an 84-inch opening. Add 12 or 16.7 inches. You can’t predict installed height from exterior width.
Option A
Thule, 639450 Black Glossy
Thule Motion 3 XL Low
This 14 cu ft box opens on both sides and takes skis up to 200 cm. It stands 12 inches above the crossbar by its published figure and has less internal height than the regular XL.
- Best for
- The vehicle clears the longer box, and your skis are 190 cm.
Facts we checked
- Longest ski length: 200 cm
- Outside width: 35 in
- Thule's threshold for front clearance: Over 52 1/8 in
- Rise above the crossbar: 12 in
Option B
Thule, 645650
Force 3 L Sport
Built for smaller loads that share the roof with other gear, this narrow box uses the Force 3 mounting and locking hardware.
- Best for
- A bike shares the roof, and your gear fits within the 175 cm ski limit.
Facts we checked
- Longest ski length: 175 cm
- Outside width: 24.7 in
- Thule's threshold for front clearance: Over 49 13/16 in
- Rise above the crossbar: 16.7 in
Spec by spec
Where they really differ
| Spec | Thule Motion 3 XL Low | Thule Force 3 L Sport | In practice |
|---|---|---|---|
| Maximum ski length | 200 cm | 175 cm | Even if you don’t need its volume, long skis can point you to the wider Low. |
| External width | 35 in | 24.7 in | In theory, Sport leaves a neighboring carrier more width. |
| Thule front-clearance threshold | More than 52 1/8 in | More than 49 13/16 in | A roof that measures shorter could take Low out of the running and leave Sport in it. |
| Height above crossbar | 12 in | 16.7 in | When screening for overhead clearance, the narrow Sport is not the lower option. |
| Cargo volume | 14 cu ft | 11 cu ft | A wider footprint comes along with the larger volume and longer ski rating. |
Trade-offs
What each pick costs you
With Thule Motion 3 XL Low
- A longer hatch clearance requirement can disqualify it on a short roof.
With Thule Force 3 L Sport
- More height sits above the bars with the narrower shell.
Change of plan
When the answer changes
I have 190 cm skis, and my car meets the hatch threshold for the Low
Go with Thule Motion 3 XL Low. That length is covered by its 200 cm ski rating, and Sport stops at 175 cm.
My skis are short enough, and my Thule front clearance measures 51 inches
Go with Thule Force 3 L Sport. For Sport the threshold is more than 49 13/16 inches. Low needs more than 52 1/8 inches.
My skis are 190 cm and my Thule front clearance is just 51 inches
Neither model fits. In that combined setup, each box fails on a different essential constraint.
Decision guide
How to decide
Decide the longest gear and the hatch together
Begin with the real ski length, then check the hatch diagram for the vehicle you intend to use. Low handles longer skis, yet its greater hatch requirement can stop the same car from taking it. Switching to a narrow box does not help if the ski still goes past that box's limit.
Keep working space next to the box
Sport is much narrower, so it is the likelier starting point for a bike-and-box arrangement. Measure the usable crossbar space around the rack feet and mounting hardware, and not just the advertised bar length. Account for lid movement and the neighboring bicycle before you approve the layout.
Overhead clearance and width are separate questions
Above the crossbars, Low’s wide shell sits lower than Sport. That counts most when a garage or covered parking route is the real bottleneck. Use the published heights to reject a setup that is clearly too tall, then measure the installed box and keep clearance for the actual vehicle and approach.
What this page can’t tell you
- These example dimensions guarantee neither a shared bike installation nor entry into a garage.
- Neither wind noise nor fuel consumption was measured in a comparison.
