Sending a bike to France

Looking at the price of sending a bike to France (not going myself) and Parcelforce seems very expensive. It is a Moulton separable frame so not too bulky but bike is quite heavy at 16kgs. Can anyone suggest an alternative carrier?
Thanks

Problem we have with shipping bikes is the size of the box..costs us on average £35 a bike to mainland uk with our shop.

Carriers have set limits anything above this gets “volumized” and becomes very expensive. One problem is that the the size is generally smaller than your average bike!
Guess they probably want around a £100+ to do it depending on the service?
