Can you adjust the length and if so what are the minimum/maximum lengths?

The minimum length that this can be adjusted to is 18" and the maximum length is 27".

What is the maximum bike weight it can support please

It says on the box. I was going to ignore but when I put it on my new heavy e-bike, I did not think it would hold and I have returned it. Shame as it is a very clever piece of kit.

What is the weight capacity for adapter?

I use this with an ebike that is around 25 kg. But it is only used to steady the bike in the carrier and therefore does not really support too much weight.
