I'm not there yet. The OEM is 50 mm/1.96 inches. So maybe the 2" coupler will fit just fine? There very well may be a bushing, something like this: View attachment 23855

Just tighten the receiver hitch tung with the adjusting bolt under and make it tighter.

I only want to haul a 12 foot aluminum boat 2 guys can easily lift onto a simple roof rack. If I can't get this electric hitch, I'll look into a roof rack for our iX 50 or the i4, if it will take this load. And I sure hope not, maybe even a roof rack for our two bikes? As you can imagine, a hitch is WAY more attractive, functional and practical.

If you are looking to have a bike rack on the EU electric hitch, I think it will not work as those do not have our traditional 2" receivers.

You would most probably better off to go for the stealth hitch that is now available for the i4.

I am pretty sure Thule has a solution for this ball size issue. Not at all sure for my boat trailer though. The two issues that shies me off the stealth hitch is cutting that hole in the underskirt and splicing wires. Also of course, the "bimmer-coding" for the stability control.
My dealer did say, they have no concerns if I went stealth hitch only for the bike rack and I didn't start splicing wires and towing stuff.
For sure, I am a purist and always want to go OEM if I can. I always have been, with most things. This for instance has a lot to do with the retained value of antiques. And especially BMW builds... mind you I came very close to adding bluetooth to my 2003 320i: Was that ever a beauty car! We kept it for 20 yrs, only needed to do brakes once, change tires and oil. She drove like the day we bought it until we sold it very recently for $1,000 to a very happy young man.

You could always use a universal non splicing Tekonsha 119250 T-Connector for the wiring harness.

In QC we can't keep our cars 20 years, just too much road salt and gravel during the winters, especially when you live near Montreal.

A little nostalgia hear best winter car I ever owned was a 1990 325 ix.
