A limo definitely not needed, Nancy can go on the top of a Suzuki Swift! The Mazda 323f we had before was great because the roofline was so low. Once you’ve got the hang of it then it is a one-person job. If you car has a high roof then a wee step might make it safer. Also have the door(s) open so you can stand on the sill. I hold the fork leg, and the diagonal down-tube, hoist it up in the air, walk up to the car, and get the tyres into the channel, then push it up to the vertical. A strap round the front crank arm onto the rack upright and she’ll stay in place while you do the other straps.
Our DIY rack is the channel section of 2 solo racks bolted end on end. The 2 uprights are the steel legs from an old bed frame, welded onto a 6mm plate that is bolted to the roof bars.
Solid as a rock!
