Gary, I would love to have a copy of the plan.
thanks, drew

Looks great. I did notice that you flipped the front half of the rack upside down. This makes sense to get the bikes lower relative to the body of the car, but doesn't this defeat the folding aspect of the rack when you don't have the bikes on it? After I get around to moving my factory hitch over to the 86.5, my plan was also to get a 1up rack, though I'll need to make an addapter from the factory hitch to the rack, I still think the 1up is the best starting point. I'll probably aim for a bit more clearance between the bike and car to eliminate any pedal to bumper contact possibility, and to be able to open the hatch with the bikes on.

Edit: That's a nice set of bikes you've got there as well. I'm guessing you do a bit of gravel with that S-Works. I just did the Mid South Gravel 100 this past weekend.

You're pretty close to Sean and Roger. Maybe one or both of them could be persuaded to make a few copies of your factory hitch while you have it off. I'd be a player for one.

Any news on this front? I like the bike rack idea. I'm looking to carry 2 65LB eBikes.

I really like Michael Benno approach.

Wonder if is strong enough to support around 200 LBs on a level arm that is almost 4 ft long. Assuming the torque would be approximately 100 LB at 1 ft and 100 LB at 2 ft. That would equate to 300 ft-lbs.

I'm putting one on my Cayenne first to see how well the eBikes travel on the rack.

Hi Simon, sorry I missed your response. Flipping the rack side plates required machining new locking grooves for the horizontal and the vertical position. I never got around to cutting the grooves for the vertical or stored position since I always remove the rack when not in use. Also, thanks for the comments on the bikes, my first passion. Hope your summer gravel rides went well. I just returned from 3-weeks Trans-Pyrenees gravel adventure (highly recommended).



Each rack will have a max load rating. Not something I have been worried about with traditional bikes. But eBikes definitively is a whole different category and I'd recommend some research on that.

The hitch system I created is nice and suitable for the rack (50lbs) and two mountain bikes (60lbs) which is significantly less than your 200lb target. As I consider your weight goals and my understanding of the design I implemented. I would be a little weary of the viability of the design at 300lbs. I would recommend making a couple of enhancements:
1. A support that prevents torsional twisting of the bumper cross member (as the bikes bounce over speed bumps). This could be accomplished by a brace from the bumper to the body (eg exhaust hanger mount).
2. Replace the bumper shocks with the solid mounts 928-505-018-20 to better handle the additional tongue weight. I see this strategy with modern heavy duty OEM hitches like on your Cayenne. The bumper shocks are replaced with solid mounts.

Michael, can I just ask, what is the receiver dimension? Is it for a 2" square hitch tube? It looks smaller, but hard to tell from photos.

I would be interested in a Trailer hitch as well

1.25" hitch. I purchased the parts for the assembly at etrailer.com

Thanks Michael. That explains how it looks.
