Has anyone used the internal bike rack with adult sized 26" wheel bikes? Is it a success? Is it worth the cost? Does it need to be installed by the dealer?

We use 700c wheels with no problems. Really is great, and so easy compared to other methods of bike transport. No need for dealer fit, although you will need to try several positions to get just right. We have had 3 bikes in. Expensive, but we have found it transforming due to its ease of use.

Thanks for your input. I'll consider this option carefully.
