Question: Does the mount hold the wheel close enough to the bike frame that you might be able to use a U-lock to secure the wheel to the bike?
Document: The wheel carrier works fine, just as advertised. Easy to mount and use. It does not have a lock and could be easily removed. I wrapped a cable lock around it, the base bar and my wheel and everything is secure that way.
This wheel carrier worked well to get the bike wheel out of our smallish car. It definitely worked better than an earlier model we previously tried. The wheel feels secure in the mount and does not spin around while you are driving. I would buy this product again- and I am picky.
I bought this item on-line. What a great product. I use these wheel forks in my 2004 Ford F150 Flare Side Pick-up. They mount to the truck bike rack. I have owned many racks through the years...all Yakima. I was a little hesitant to buy a Thule rack system. However I must say that this is a well made system and works very well. I have a Yakima on my Subaru with kayak Land Sharks and both racking systems are great.
The wheel also cannot be locked to the carrier aside from tightening down the quick release mechanism. The only option is to use a cable lock looped through the spokes and around your rack which looks a bit cheesy. It works, but a factory fit lock would be a nice change.
I bought these to hold our front wheels when we had the Forester loaded up with other junk. Seems silly to run these along side fork mount carriers (instead of a full, two-wheel carrier)... oh well. Most of the time I can toss the wheels in the trunk. For longer trips with a packed vehicle, these work well. There was some flutter with the tires while in the carrier...
This is an improvement over the older Wheel-On design. I do wish they'd kept the mesh strap for added piece of mind, though. It was easy to mount the unit to my roof rack and the wheels go in and out easily and the quick releases lock down more easily than with the old design.
I use this carrier on a Yakima Rack. I had the Yakima wheel holders but I couldn't get it tight enough on the bars. The Thule, with the four screws, allows me to tighten the mounts so they rotate less on the bars. I also like the slots that allow you to get the tire against the anti-spin feature so the wheel isn't spinning madly as you go down the highway.
I agree with other posters that this product would be even better with a lock, however the product does exactly what it is intended to do and does it well, so I can't knock a star for that. I recently moved 900 miles across the country with my bike on the Thule 518 and the front wheel on this. It didn't even flinch... and this was going up to 85 mph and partly through the windy mountains of West Virginia. I also didn't hear any wind noise. Highly recommended.
I really like the wheel caddies.. You can fold them down when not in use, you can move them around with the wheel in the mount to fit the bikes on the roof perfectly. It's a major upgrade from the old fixed ones.
I purchased this wheel carrier since I have the fork mount bike trays I stalled on my roof rack. It makes travel with my bike so much easier now that I don't have to store my front wheels in the trunk. Absolutely ingenious idea and another great product from Thule.
