The Loopwheels’ spring system between the hub and the rim cushions the rider from potholes and bumps in the road. It also reduces road noise by absorbing it, thereby reducing vibration through the frame—and into the rider’s arms and body. Because the suspension is inside the wheel, you don’t need fat tires to make the ride nicer. Instead, you can use high-pressure or puncture-resistant tires.
My background in wheel performance is its circular motion( which involves the circular of the wheel, and that the hub remains in the center of the wheel) if u are rolling with an oblong wheel, then u may actually exert more effort in lifting your self with the bike rather than rolling.

You can't play with the Hot Wheels without TRACK !! This is the best buy and price !! My grandson will love the track !! My grown up son and I played with track and it 's fun !! Great Buy !!
unlike other bikes I purchased, I did not have to make any tuning/adjustments for the deralleurs - hope this won't jinx it. The bike arrived very fast and only a little assembly to do and very easy. The gears change very smoothly. It's a little heavy but I'm very satisfied !!! Had bike for just over a month and gears don’t work proper and back wheel frame is bent and has a wobble. Thought getting a more expensive bike would be more durable but I was wrong. My 200 dollar Canadian Tire bike was better. The tires are missing some ball bearing and trying to put the tire on only results in a wobbly tire. Off to buy some ball bearings now... Grumble.
