Thanks, I had been looking at the more expensive Thule carriers (and the Atera Strada which looks as if it might perhaps be better), but hadn't really considered these more budget 9403 ones. Given that this ebike lark is proving rather expensive already having just bought two bikes, and a dog trailer, and accessories, and a shed to put them in, and a concrete base for the shed, and a gate and path constructed to give access for the bikes and shed building materials, and I don't even have a towbar fitted yet - I don't mind saving a bit
Looking at some reviews of this rack there are a few folks saying that it can move/flop around at speed when the road surface is uneven, is that unlucky/incompetent assemby/paranoia or just a limitation of the budget model?
P.S. The cube bikes we have are barely over 20Kg each, even with the batteries which I would remove, so loading should be well within the limits of most of these racks I think, including the 9403.
