I ordered this on the recommendation from a buddy who works at a bike shop. He is a keen mtb rider and has used Mac Ride for some time now.
Mac Ride is very easy to install and remove from the bike. It's comfy for the kids and not to restrictive for the rider.
Seems good quality and very robust. I have a carbon Santa Cruz and I'm happy that Mac Ride doesn't even touch the frame so no danger of damaging it.
The most important thing is that my kids love it.
