I have a temporary lash up a bit like this, I can get 6 bikes cross ways behind the rear seats - although do have to rotate bars, probably wouldn't fot 3. I will use the sasme system on top of my rear arch height storage box, one I have made my rear arch height storage box! QR font and slot for rear wheel seems the way to go.that wont fit because of the arch though will it?
i need something too
was going to make a bracket that i can put a hub on and qr then bolt to floor then just take front wheel off and clamp in hub
