I spent about 20 minutes out with Sam on the 20″ wheels, coupled up with the Dahon folding bike, and immediately there is something special about them.

Have you owned this car from day 1? because that's definitely not sitting at the stock height. lol.
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
it's not THAT low, but it's low...lower than recommended by this site and every wheel shop. some go as far to say that they just won't work!!

Over the winter of 2014-15, we’ve been developing and trialling our first 20 inch loopwheels designed especially for recumbent trikes. The springs are designed to cope with fast cornering and the particular forces of side-axles. We’re really happy with the results. Loopwheels-builder Graeme cycles the 12 miles to work on his trike most days – fitted with loopwheels, of course. He’s been pushing us to get these ready to share! We showed these new trike wheels at the Spezi show in Germersheim, Germany on 25 and 26 April 2015, along with another new design for trikes, with our own hubs and a disc brake fitting.

Loopwheel springs are made from a carbon composite material, carefully developed and tested to give optimum compression and lateral stability as well as strength and durability. Specially-designed connectors attach the springs to the hub and rim. The three loops in each wheel work together as a self-correcting system. This spring system between the hub and the rim of the wheel provides suspension that constantly adjusts to uneven terrain – cushioning the rider from bumps and potholes in the road. In effect, the hub floats within the rim, adjusting constantly as shocks from an uneven road hit the rim of the wheel. The spring configuration allows the torque to be transferred smoothly between the hub and the rim.
The forces imposed on the anti-roll bar subject it to constant twisting and flexing, which in turn put its various rubber mounting bushes under great load. The bushes gradually wear and lose their effectiveness. Over a period of years the rubber hardens and tends to crack.
The sale of Bacchetta Cycles was in the news since our last webcast. We have former CEO Mark Swanson and new owner Dana Lieberman with us for interviews. Along with the rest of the recumbent news is Honza Galla.
MacPherson-strut suspension can be used at both front and rear. The wheel hub is fixed rigidly to an upright, telescopic, tubular strut which has its top end anchored to the frame or to a reinforced wing.
Durable aluminum frame: Built to last, our kick scooter is made with a high quality aluminum frame, stainless steel alloy & adjustable T-type locking handle bar.
I find it difficult to credit the coach moving down the hill with 20,000 - 40,000 lbs of motorhome pressing the jack pads into the earth. That assumes the jacks are rated for the full coach weight and don't break under the load. My 36,000 lb coach had 4 x 16,000 lb jacks, so I wasn't too worried. Back in the day some coaches had poor frame rigidity, especially up front, so the front cap and windshield frame would often twist if the front wheels came off the ground. My '96 Southwind (F53 chassis) was like that and I avoided ever lifting the front to even barely touching cause the windshield would start to move. My 2002 W22 chassis coach didn't seem to have any problem with that but I was still careful. My 2004 DP was stable as a mountain no matter how much it was jacked. Spent many a summer at my brothers home in SW PA with wheels off the ground. He lives on a hill side and the 2012 Tour never had a problem.
