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.
Generally, only very high-end wheelchairs have shock absorption built in, necessitating wheelchair-accessible entrances to buildings. “It’s difficult and painful to use a wheelchair to cross the street, with the chair’s rider feeling the strong impact of a chair going off the sidewalk and onto a curb,” said Barel. “With a SoftWheel-equipped chair, a wheelchair user can cross streets or go down steps without feeling the impact.”

Loopwheels are currently available in a 20-inch size for bikes and a larger size for wheelchairs. They are working on 26- and 29-inch wheels for bicycles. They are currently available as a retrofit for Dahon or Tern foldingbikes and have a 100mm front fork for the changeover. The wheels themselves cost $462 US while a Loopwheels folding bike will set you back $1,493.
I started to remove the bike and it came out easily. I began removing the padding and cutting zip ties. Everything looked great although I was a bit concerned as there were no instructions included. Upon further unpacking, I could easily see there were minor steps to assembly which became self explanatory. I screwed in the right peddle and a small bearing fell into my hand. I called the number on the bike and explained the situation. In under 10 mins, a new peddle was on its way free of charge. I completed the assembly and took it for a test drive. The bike felt solid and drove like a champ! This is going to be a fun bike to use on the trails!! Bike arrived yesterday, so I put it together last night, and attempted to ride it. The gears don't change properly, and the chain constantly runs on the chain guard. Tries to adjust the gears, but to no avail. I got it close but either the chain runs while pedalling l, or the gears don't move to the next sprocket when the trigger is pulled... I'm going to try again tonight after work, bit I'd like to talk to the seller a out this issue.... a brand new bike out of the box should change gears.... I think.

Richard Quest, the designer of LoopWheel, asks “Why can’t the suspension work in all directions?” in regards to conventional wheels. Hence, the idea of LoopWheel originates. A 20-inch Loopwheel with Shimano Alfine 11-speed hub weighs 2.13kg. A LoopWheel is about 300g heavier than a conventional spoke wheel of the same size. However, you do get the added suspension and a smoother ride.

If you don't mind...what are the full specs of your wheels/tires? I'm just wondering because I have the X model and I know the widths and everything will be slightly different and no staggering for me. I think your setup looks great considering no drop, but I don't know how it would compare to an X model with no staggering or spacers etc.
Hi we are new to a air ride equipped motorhome and are wandering if it is ok to lift the wheels off the ground with the Jack's when leveling on those unlevel sites, the chassis is a Freightliner XC and it seems like the air bags are really stretched if the wheells and everything are pulling down on them in this situation ... We just do not want any damage to the system. Your input would be appreciated thanks The weight of the axle pulls down on the air bags but the weight of the front axle assembly is supported by the length of the shocks. When the shocks become fully extended, air bags, leaf or coil springs, that's when the front axle assembly quits moving down. I'm with everyone that doesn't like the looks of wheels in the air, but it doesn't hurt anything and I have done it. Think about this: The only way your motorcoach can roll away is if it's on the wheels. If it's up on the jacks, it can't roll. A good backhoe operator will hike the rear tires (where the brakes are) up in the air to get it up on the hydraulics where it is solid and stable, before operating. Sometimes they raise the front tires up with the bucket. Ever seen a mobile construction crane? First thing they do is raise all the tires up off the ground to get the unit level and stable before operating. I'm not saying to lift your coach that way, but it's not the big deal that some people try to make it sound like. On my Freightliner with the stiff rear end and V-Ride, if I lift one side a couple inches, the duals will come off the ground. Not a big deal because the jack won't roll.
