“First of all, it is symmetric to absorb shock in any direction," Rozanes told From the Grapevine. "Second, selective suspension means if you drive normally on flat surfaces, there’s no suspension unless encountering an obstacle."

The Loopwheel works using three heavy duty springs instead of spokes. When the rider hits a bump, the springs compress to give a smooth ride
I was happy with my purchase until this point. The bike looks nice and handled great. The only issue I noticed before this was that the left gear (I’m no bike expert, sorry if if that’s not the correct term) sort of made a weird noise when switching between one of the three settings (the chain sort of took a while to set correctly). The right gear worked flawlessly.

Panthera X Wheelchair

on flat ground due to the hub always being nearer the ground than the top of the wheel, all three “loops” have to flex and return for each revolution of the wheel, meaning it would be like going up a gentle hill all the time (work wise)? (unlike conventional suspension that will flex due to riders weight and stop regardless of revolutions.

Design concern: Compressing the suspension changes the center of the wheel. When the wheel is also rolling this means there needs to be a ‘handoff’ between the three struts. The result will be the translation of energy in to compressing the next strut which will slow the wheel. Torquemada on May 21st, 2016 - 9:39am

    While entirely theoretical, Lee’s design is not without merit. Spokes and rims found on any standard bicycle already absorb shock, albeit minimally.

    How does it constrain the axial translation and the 3 rotations? Is is springy in all those 4 directions as well? Greg Mixson April 18, 2013 01:24 PM

    ko2's are more like 1k. unless he puts on some P rated stock size ones. which seems silly. $800 on Amazon for C load 285's - so I was a little off. I was also assuming prices of shopping around, or else the SPC's would've been stated a bit higher. Reply With Quote 03-15-2020, 11:03 PM #5

    The spring system between the hub and the rim of the wheel cushions the user from bumps and potholes in the road. The springs absorb road noise, reducing vibration through the frame and into the rider’s arms and body. High-pressure or puncture-resistant tyres can be used.

The fact that each shock is individually adjusted and tuned makes me wonder how difficult it would be to get them synced and the negative effects of them being out of whack with one another. Colin M on May 20th, 2016 - 10:53am nightfend on May 20th, 2016 - 10:59am

The steering and suspension systems are important for both your safety and comfort when driving as they ensure a smooth ride as your car travels over bumpy roads. The two systems are usually talked about together as they are directly related to each other. However, what does each system do? When do you need to check these important systems? And, how can you tell if either system is damaged in some way?

OK, so this would feel weird, as as the ‘suspension’ compresses, your pedalling torque curve would change due to the wheel changing shape….?? Ventruck on April 14th, 2013 - 7:30pm Dan on April 14th, 2013 - 7:58pm
