Engineered with precision
We believe in taking pride in making things by our own hands, which is the literal meaning of manufacturing. So we make loopwheels ourselves, by hand, in Nottinghamshire.
We can’t claim that every component of a loopwheel is local or British, though perhaps we’ll get there one day. But we are proud that the springs are made just a few miles from where the loopwheel was invented, and that we assemble our wheels in Nottinghamshire too.
We care about nurturing creativity, our engineering skills, and manufacturing. We are not nostalgic or sentimental about it: we just believe in making and doing, and making and doing it well.
North Nottinghamshire was once the home of the infamous outlaw Robin Hood. Little of the ancient greenwood of Sherwood Forest remains today, but there remains traces of the ancient crafts. We believe in the skills and knowledge that come from practical experience. Loopwheels inventor Sam Pearce worked with a local company, KG Archery, on the development of the springs for loopwheels. KG Archery upholds the ancient skills of making bows, though with modern materials as well as wood. Master Bowyer Keith Gascoigne began his apprenticeship in 1962, and in 1991 developed the world’s first all carbon bow handle, the Paragon. His team at KG Archery are proud to be celebrating over 50 years in bowmanry and taking their expertise into new territory with Loopwheels.
What are loopwheels made from and what do they weigh?
More about loops
These are leaf springs made from composite materials including carbon, which we have developed specifically for loopwheels. They’re very strong and durable. We use different formulations of composites to give different compression rates and spring rates, depending on the application. So our bicycle 20″ front wheels have softer springs than our bicycle 20″ rear wheels (because most of the rider’s weight is carried on the rear), and our 24″ and 25″ wheelchair wheels have much stiffer springs again, because that’s what wheelchair users told us they wanted. Once made, the loops can’t be adjusted or tuned.
Where can I find out more?
General information is on our About Loopwheels page. We try to provide as much specific product info as possible on each product page. If you have a question we haven’t answered in any of these places, try our FAQs or drop us an email at firstname.lastname@example.org.
The springs are a composite material with a high amount of carbon fibre.
Rims, rim connectors and hub connectors are aluminium.
Our own hubs are die-cast aluminium; some of our 20 inch wheels have proprietary hubs made by well-known brands Sturmey Archer or Shimano.
Loopwheels are heavier than the same wheel with conventional spokes. For example, a 20 inch loopwheel is about 300g heavier than a conventional spoked wheel with the same hubs. But for this, you get suspension as well as a wheel!
Here are weights of our loopwheels, without tyres:
24 inch loopwheel for wheelchair (no push rim): 1.8kg
25 inch loopwheel for wheelchair (no push rim): 1.85kg
20 inch front Loopwheel with drum brake: 2.05kg
20 inch rear 3-speed Loopwheel with drum brake and hub gears: 2.95kg
20 inch dérailleur rear Loopwheel (no gear cassette): 2.48kg
20 inch loopwheel with Shimano Alfine 11-speed hub (no disc rotor): 2.13kg
Our Custom Built Testing Environment
The development of loopwheels took more than 4 years before the public launch in 2013.
Sam Pearce is the inventor of Loopwheels. He has a degree in mechanical engineering, and a masters degree in Industrial Design for Engineers.
Sam put loopwheels through extensive research and development. He first used an external, independent test house to verify the prototype loopwheel. We later set up the same test machinery in our own facilities, to ensure we continue to meet high standards of technical performance and safety.
Our test programme comprises mechanical testing on test machines, and real-life off-road riding and user evaluation.
Each time we introduce a new variant of wheel, for example, we put it on a rolling road machine for 10,000 miles before we are satisfied that it offers durability for our customers.
We continue to test our wheels to assure the quality of each product and of every new product development. We code every wheel to identify it. We want you to have a lifetime of enjoyment with loopwheels, so we build each one with precision.
