But what? Well I have 2 electric bikes to carry on the back of my caravan and they are heavy. Not too heavy for this product but they have to be lifted on and that is awkward. I ordered this bike rack and apart from the lifting, it does the job very well. The bikes travelled securely and safely but, shortly after buying this rack, I discovered that Thule have released another rack which actually lowers and lifts so that loading is much easier. That's the but. Consider the newer products before you buy.
I also wanted a bike rack cover and bought the Thule one. It was quite expensive compared to other makes but I can't see why. Others of similar design are £20 - £30 cheaper, so I think I paid for the name.
All in all I am very pleased. Fitting was fairly straight forward, just a couple of situations trying to understand the instructions, and I feel robbed about the cover.
Shop around before you buy. I found that prices varied by as much as £50 for the same product.
