I have used a Radical two wheeler that hitches to my ICE trike. There are different designs of hitch bracket available from Radical (Std, Brompton / small wheel, and another which I forget). But whilst I would ideally suggest some metal is removed from the bracket to make it a better fit, (plus the qr has to be turned vice versa to accomodate), the ICE copes admirably with the bracket attached to one side of the 700c wheel.
Ok the ICE is for racing, (have you missed Chris Foy, Brad Wiggins or Chris Froome with their trailers in the TdF - clearly you werent watching closely enough🤣 ) but occasionally the need to tow camping or other gear is required and banana bags are not always enough.
