I'm not talking about 3 e-bikes. But 3 bikes no matter what is the weight, i'm talking about the distance between each bike.
There's enough options then if you look.
I don't think Thule do anything suitable, they didn't when I looked anyway, which is surprising from possibly the biggest manufacturer of bike racks.
Atera do a couple of options, if you can find stock.
I bought the XL e-bike rack, and made a modification to the third bike extension piece to suit a large bike. I also bought longer straps for the wheels and the frame clamps, to go round fatter frames.
I love how it works compared to my old rack, which was designed for narrower bikes. Plus I can get in the boot with this one, which I couldn't with my old one.
On the car that I use for going biking, the boot swings open like a door, rather than lifting up (Suzuki Vitara) and, whilst it still doesn't open wide, it opens enough to get stuff in and out, access the power wash I've got (just a battery thing, not high pressure).
I'm happy with the whole transport package now for forests and bike park trips.
I have three bikes on the rear rack, and two on the roof for when there's a car full of people.
