“Selective suspension is the key to the mechanism because constant suspension creates loss of energy, making pushing more strenuous. Only when encountering an object does the suspension system activate, making the inside of the wheel, the hub, move and absorb most of the shock instead of the wheelchair user’s body,” she said.
That first grant helped us to develop our first loopwheel for wheelchairs. Getting the support from Innovate UK was crucial to us. We should have applied for R&D support earlier, it would have helped us to get a lot further a lot faster.

Looking good fellow Sandy Eggan! haha. Wish they came in other colors like a gunmetal/anthracite. Joined Jan 14, 2018 Messages 15 Reaction score 10 Location Sactown Car(s) CivicX

An important consideration when dealing with e-tron is the aforementioned weight. Though smaller than the SQ7 TDI sold in Europe with its heavy V8 TDI engine, the e-tron is still some 400 lbs. heavier. If you go with a wheel that’s not weight rated for your car, you could find yourself easily bending your wheels or even worse. We did our best to find out what we could about the weight rating of the SQ7 wheel and came away confident enough to give it a try. Even still, it is heavier than stock and boasts a wider contact patch, which meant our electric range would suffer.
The big limitation that I can see, is that if there is any deflection when the rider gets on the bike, that means that the rider is essentially pedaling uphill all the time (Because he has to compress the springs as he moves forward). The other problem is that unless the springs are precisely calibrated to the riders weight this will really destroy the rolling efficiency of the bicycle. Malcolm Jacks May 23, 2020 03:09 AM

When installing the wheels, lugs should be hand-torqued in a star pattern and not installed using an impact tool.
So, how did it turn out? Did I like the trike? What are the good points and bad? Before we get into that, I’m sure that there are many who want to see the specifications, and not have to read through to the end for that. So, here goes: Amazing New Bent Builds on Laidback Bike Report! Posted on June 5, 2021 by Larry Varney Today (Sunday, June 6th, at 2 PM EST), we literally get into the weeds with our Italian bent builder Marco Ruga. He has created an amazing off road long wheel base recumbent and will show us how he did it and where he rides it. Then Englishman Alex du Pre (who is a naval engineer) reveals his first recumbent design. A tilting trike/velomobile made initially out of wood. Doug is back with another gonzo bent road fix and we have two new Review Team segments: Joseph Janning from Germany talks about velomobile wheels and Mickey O;Brien from Laid Back Cycles in California reviews the ICE Adventure trike. Denny will cap it all off with the latest in sports and Honza has our recumbent news of the month. You can catch it all on YouTube Sunday, May 2nd at 2 pm ET or anytime thereafter right here: https://youtu.be/Zv7iotthpi0 Head over there now and click the “Set Reminder” Button! Live chat with our guests or panelist and be part of the fun. If you have questions/comments for our guests and can’t watch live please feel free to respond to this post and I’ll try to ask for you during the show.

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.
No new devices or components shall be allowed that deviate from accepted standards & practices.
With any wheels there is always a little trepidation about hitting larger more inanimate objects but with Sam goading me on I started to aim for rocks, ruts and tree roots (did I mention we were riding off road!!!) and in every instance the wheels soaked up the impact, leaving me free to ride the bike without worry of knackered rims, aching arms or even getting up out of the saddle to soak up the impact – you can just let the wheels do the work.
A Kickstarter project has already raised £48,000, exceeding the £40,000 target needed to get production started, and Mr Pearce, who is developing the wheel with his wife Gemma, admitted he was stunned by the response.
