Fitting

  • Do loopwheels fit any wheelchair?

    Loopwheels fit ALMOST any MANUAL wheelchair. Loopwheels are not made for power chairs - those wheels are generally much much smaller! We make Loopwheels Classics and Carbon in the standard wheelchair sizes of 24" and 25" diameter (ETRTO 25-540mm and 25-559mm), Loopwheels Urban in 24" diameter (ETRO 25-540mm) and Loopwheels Extreme in 24" diameter (ETRO 47-507mm). All are fitted with standard ½ inch and 12mm bearings. That covers some 95% of manual wheelchairs in the world today. (That's a guesstimate - but we do mean the VAST majority). We don't make a 26" diameter Loopwheel yet. Few people have these big wheels, but if you're very tall, you may have them. We're sorry we don't yet have a Loopwheel for you. We don't yet make a Loopwheel that is compatible with a one-handed drive. Again, we're really sorry that we can't yet produce a Loopwheel that works for you. You can't use a Loopwheel on chair that has a fixed curved fender or sideguard that comes over the top of the wheels and is not adjustable, as the wheels will hit this when the suspension kicks in. To fit Loopwheels, you would need to adjust the guard to allow at least 30mm space between the fender and the wheel. If you've had a special adaptation to your wheelchair so there are extra fixtures sticking out on the side of your chair, you may need to have that fitting taken off to enable a Loopwheel to move freely and fit your chair. But Loopwheels have standard fittings and use standard quick release axles, so they are interchangeable with most wheels on most manual wheelchairs made by the major manufacturers e.g. Sunrise Medical, Invacare, Ottobock, Ki Mobility, Karma . . . etc etc. Please contact your local stockist if you are unsure about your chair.
  • What are my pushrim options?

    We are the UK distributor for CarboLife, a German brand of ergonomic hand rims that are designed to optimise comfort for a number of hand functions. We are also able to supply Tetra Gripp pushrims to fit Loopwheels. Please visit our product page for more information, or email [email protected] if you require a rim that we do not advertise.

General

  • Is there a minimum and maximum weight limit?

    Yes. Each product we've developed (Loopwheel for wheelchair, Loopwheel for bikes, Loopwheel for trikes) has been optimised for different weights and applications. The maximum weight covered by the warranty is shown on the product page of the item (under "technical specifications"). The more you weigh, the more you will feel the benefit of Loopwheel suspension in the Classic and Carbon models. If you weigh less than 50kg (about 7st 12lb), you may not feel as much benefit, because the springs are optimised for average and heavier adult weights. We recently developed a spring rate system for the Loopwheels Urban and Extreme that allows us to optimise suspension for users of different weights. It also allows customers to chose the suspension that is best for them depending on their daily use, average speed and most common terrain. The Loopwheels Urban has three spring rates: Soft, Regular and Stiff. The Loopwheels Extreme has two: Regular and Stiff. Please visit the product pages for more information.    
  • Can I fit solid tyres to my loopwheels?

    We no longer supply solid tyres to be used with Loopwheels and do not recommend their use.
  • Can I change the colour of my loopwheels?

    Loopwheels Classics are available in the colours: Black, White, Blue, Red and Orange. We are also able to do a range of multicoloured options. The springs are integral to the structure of the wheel and therefore cannot be changed once they have been made. If you're not sure on a colour, why not choose black? You are able to choose from a wide range of logo colours that can be changed. The Loopwheels Carbon, Loopwheels Urban and Loopwheels Extreme are only available in a sleek carbon finish and with the logos built into the springs.
  • Is the suspension on loopwheels adjustable?

    It's not possible to change the amount of suspension on your loopwheels. Each loopwheel we've developed has been optimised for its specific application and for a certain weight.  For example, our original front 20inch bike loopwheel was much softer than the rear bike wheel, as most weight of the rider is carried at the rear of the bike. People tend to want a lot more suspension on a bike than they do in wheelchair wheels. So our wheelchair wheels are stiffer than our original bike wheels. More recently we have been able to develop the Loopwheels Urban that has three different spring rates and the Loopwheels Extreme that has two. The spring rate allows for the use of wheels in different situations depending on factors such as the average speed of travel, user weight or even the terrain that the wheels are being used on. All were developed with the goal of further reducing the effects of whole body vibration being felt during the use of a wheelchair. Please get in touch with us via [email protected] if you have questions about the differences in spring rates.
  • How does the rolling resistance of a loopwheel compare with a spoked wheel?

    • Surprisingly well! We tested the Loopwheel against a spoked wheel to measure the rolling resistance. Because the loopwheel is not held back by any obstacles it encounters, it will actually travel faster and more easily than a non-suspension wheel if there are small or large bumps in the road/pavement/track. Find out more about the test here
    • Don't forget that the biggest cause of poor rolling resistance is if your tyre is not fully inflated: make sure you're pumped up!
    • Solid tyres are much more resistant to moving than a good quality air tyre. We recommend Schwalbe Marathon Plus, designed for wheelchairs and puncture-resistant. We don't recommend using solid tyres.
  • Why are some products VAT exempt? When do you charge VAT?

    There are lots of rules about VAT, including a UK exemption scheme for products designed for people with disability. Tax law is complicated -  for expert advice, ask HMRC! This is our understanding of the rules on disability exemption, applying to individual UK & EU customers, and the rules for exporting outside the European Union (EU). Export outside the EU If you are buying from outside the EU, no VAT is charged. But you may have to pay your own country's taxes or import duty to the delivery courier when they deliver your goods. UK Disability VAT relief scheme All Loopwheels for wheelchairs qualify for VAT exemption when bought by UK and EU customers from our UK website for personal use. The scheme considers firstly the type of goods and secondly who is buying them. Not all goods used by disabled people are exempt from VAT. The goods qualify for exemption if they are designed solely for personal use by a disabled person or are specifically adapted for their personal use. (EU customers are eligible at least while transitional arrangements to the UK leaving the EU apply). Some other products that we sell are not eligible for Disability VAT relief. VAT may be charged on the cost of shipping/delivery. The cost of servicing, adaptation and repair of exempt items is itself fully exempt. This relief applies only to the cost of the service provided; the cost of any parts used may not necessarily qualify for relief. Obviously, this is quite complicated if several items are bundled together in your order. Some may have VAT applied and others not. If you qualify for VAT Exemption then you will need to complete the VAT Exemption Declaration during the registration process prior to placing an order. The VAT amount will be adjusted accordingly at check out. It is your responsibility to provide the VAT exemption statement truthfully (and answer to HMRC if you make a false declaration); we are not required to check your disability. We are required to keep a copy of the customer's declaration to show HMRC when they inspect our tax records. Full details can be found in HM Customs and Excise, Notice 701/7, Supplies to handicapped people and Supplies to charities. We hope this is a helpful guide - we are not tax experts - do consult HMRC if you're not clear!
  • Where can I buy loopwheels?

    In the UK and elsewhere, you can buy direct from us via the "products" page on this website, or by contacting us on [email protected] Check out our stockists page for where you can buy Loopwheels for wheelchairs in your area or country if you would like more personal advice. Our Stockists page lists our international distributors, as well as direct re-sellers and dealers. This page also lists our exclusive distributors for a country or region, please get in touch with them to find out where you can buy Loopwheels. They will be able to direct you to a stockist near to you or put you in touch with a sales rep in your area, even if one is not listed on our stockists page. Between 2013 and early 2017 we made 20" Loopwheels for folding bikes. These are no longer in production, and are not sold through any of our stockists, as in 2016 we took the decision to focus on wheelchair Loopwheels. Sorry if you missed out! Contact with [email protected] with any questions.
  • What about 29 inch wheels?

    Sorry - we don't yet make a 29-er loopwheel. Sign up to our mailing list if you'd like us to tell you about new products as we develop them.
  • What about bigger wheels? Do you make MTB wheels?

    We intend to bring out loopwheels for bikes (MTBs) in the future. Bigger sizes are technically challenging. With any wheel, the larger the diameter, the less the lateral stability. We're developing a MTB loopwheel  - slowly! Sign up to our mailing list for updates via our newsletter if you want to be among the first to hear news on this and our other product developments.
  • How much does a Loopwheel weigh?

    Loopwheels can be slightly heavier than wheels with conventional spokes. But for this, you get suspension as well as a wheel! Here are weights of our loopwheels, without tyres:
    • 24 inch Loopwheels Urban: 1.3kg
    • 22 inch Loopwheel Extreme; 1.36kg
    • 24 inch Loopwheels (no push rim): 1.8kg
    • 25 inch Loopwheels (no push rim): 1.85kg
     
  • How bouncy or stiff are Loopwheels?

    Loopwheels are actually quite stiff!
    The loops are made of a composite material with natural damping characteristics.  They are surprisingly stiff, so the springs only flex when they need to, to make you feel more comfortable and give you wheelchair suspension when you need it.
    Our Loopwheels Classics and Loopwheels Carbon only come in one spring stiffness. The New Loopwheels Urban and Loopwheels Extreme come in three spring rates: Soft, Regular and Stiff. Please visit your local stockist to try the selection of spring rates or contact [email protected] for more information.
    Rear wheels for bikes and trikes are stiffer than front wheels, to suit the rider's weight distribution.
  • Is the concept of the Loopwheel suitable for smaller wheel sizes?

    Yes, it is.  In theory it is possible to design smaller Loopwheels for bicycles and other applications. We're working on some other stuff but it will take us a while to perfect these variants.  If you want to find out more, you should subscribe to our newsletter, as that's where we'll share any updates on new products.  We send a newsletter every month - more often when we have lots of news to share!
  • Is the suspension in a Loopwheel optimised for a particular weight load?

    Yes it is. Check the product details for each Loopwheel. We advise a maximum weight load for each type of wheel.
    Our wheels are designed for adults. Small children and some very light adults may not feel the full benefit of loopwheels suspension except when you hit a bump with real force.
    In the future it may be possible for us to offer a range of different wheels for much lighter and much heavier riders.

Wheelchair

  • What is the maximum recommended camber for a loopwheel?

    Loopwheels must not be mounted at a camber angle that exceeds 12 degrees. We recommend an optimum camber of 6 to 8 degrees for Loopwheels Urban and Extreme.

    Loopwheels fit ALMOST any MANUAL wheelchair. Loopwheels are not made for power chairs - those wheels are generally much much smaller! We make Loopwheels Classics and Carbon in the standard wheelchair sizes of 24" and 25" diameter (ETRTO 25-540mm and 25-559mm), Loopwheels Urban in 24" diameter (ETRO 25-540mm) and Loopwheels Extreme in 24" diameter (ETRO 47-507mm). All are fitted with standard ½ inch and 12mm bearings. That covers some 95% of manual wheelchairs in the world today. (That's a guesstimate - but we do mean the VAST majority).

  • Will I need to buy new axle pins?

    It might not be necessary to buy new quick release axles as your existing axles are likely to be compatible with your new loopwheels. We stock various sizes of axles so we can supply you with new ones if your existing axles don’t fit. Our range includes both ½” (12.7mm) and 12mm width axles, in 99mm, 104mm and 109mm lengths so we’ve got a wide selection if you need it.
  • Which length axle pin is right for my chair?

    We have found 104mm to be the most common axle length, but all wheelchairs vary and may require a longer or shorter axle pin. If you’re not sure which length is right for you, check out the diagram and/or drop us an email. We also stock 99mm and 109mm lengths, and may be able to obtain other alternatives too. Each axle is adjustable at the head up to about 8mm in length. We also supply 3 spacers with each axle (2 metal and one rubber) in case minor adjustments are needed for a better fit.Quick release axle measurement Measurements of our 104mm quick release axle. L = 104mm; L1 = 45.9mm and is the part of the axle that passes through the wheel. L2 is the part of the axle that goes into the chair.
  • How do I adjust my axle pins?

    Minor Adjustment.  The length of the Loopwheel axles can be adjusted by rotating the ‘Nut’, clockwise (shorter) counter clockwise (longer). This is done by clamping the ‘Flat section’ and turning the ‘Nut’ using a suitable spanner. Total adjustment is approximately 8mm.How to adjust an axle pin
  • 12mm or ½ inch diameter?

    The answer to this question will depend on the type of wheelchair you want to fit Loopwheels to. As most chairs are made with 1/2" (12.7mm) diameter axles, we fit 1/2" bearings as standard. This means that you must tell us if you require a 12mm diameter bearings in your wheels. If you already have 1/2" axle pins with your chair it is likely that you will not need to replace them. However, due to the larger hub on the Loopwheels Classics, there may be a need for longer axle pins, though this is rare. This should also not be a problem with the Loopwheels Urban and the Loopwheels Extreme as the hubs fitted to these wheels are smaller and more streamlined for the chair. We are also able to make Loopwheels with 12mm diameter bearings as some chairs do use this size rather than the slightly larger 1/2 inch. If you are unsure about the size of your bearings please do measure them or check with your wheelchair manufacturer before you place an order with us. A 1/2" axle will not fit into a 12mm bearing and a 12mm axle will wobble in a 1/2" bearing, both of which are situations that should be avoided. Please contact us if you are unsure about any of this at [email protected]  
  • Can I swap out the bearings on my loopwheels?

    Removal of the bearings may seriously damage your wheel and will void any warranty that covers this. Do not remove or change the bearings yourself. If you need them swapping out please seek advice from us at [email protected], or talk to your local dealer. It is our standard practice is to fix the bearings into the wheel hub with a 'Loc-tite' glue. We offer two sizes of axle bearing ½ inch (12.7mm) or 12mm. The most common size is ½ inch.
  • What is the recommended tyre pressure for the Schwalbe Marathon Plus on loopwheels?

    The recommended tyre pressure for a Schwalbe Marathon Plus tyre is 6.00 - 10.00 Bar (85 - 145 psi). We recommend you keep your tyres well pumped up as soft tyres require more effort to push and the tyres wear our more quickly. We supply our wheels pumped up to 100 psi.
  • Can I fit different tyres to my loopwheels?

    If you need to purchase or change the tyres, we recommend Schwalbe Marathon Plus wheelchair tyres. It is the most popular tyre on the market and according to Schwalbe (and many of our customers) it is the most puncture resistant pneumatic tyre available. If you would like to purchase your own tyres you will need the following information: Each wheel type has a BSD (Bead Seat Diameter) which is the diameter of the rim. Loopwheels Classic, Carbon in 24" and Loopwheels Urban BSD is: 540mm Loopwheels Classic in 25" BSD is: 559mm Loopwheels Extreme BSD is: 507mm You can use this number to indicate the correct ETRO number for the tyres you need. You can usually find the ETRO code on the size of the tyre in a white. All tyres of the same size have the same ETRO code. We use the following: Loopwheels Classic, Carbon and Urban 24”:    25-540 (24 x 1.00 inch) Loopwheels Classic and Carbon 25”:    25-559 (26 x 1.00 inch) Loopwheels Extreme: 47-507 (24 x 1.75 inch)
  • Can I fit solid tyres to my loopwheels?

    We no longer supply solid tyres to be used with Loopwheels and do not recommend their use.
  • Do loopwheels require any maintenance?

    Loopwheels require very little maintenance other than an occasional clean. We advice you wash your wheels with warm soapy water if required – avoid aggressive abrasive cleaning agents. We recommend you keep your axles cleaned and oiled regularly to aid ease of use and to avoid a build-up of residue oil.
  • Are loopwheels wider than a standard spoked wheel?

    A Loopwheel Classic and Loopwheels Carbon are no wider than a standard spoked wheel at the centre of the hub. However, it is slightly wider (by 7mm) where the loops meet the hub, as illustrated on the diagram. Widest point on a loopwheel for wheelchairs The hubs on both the Loopwheels Urban and Loopwheels Extreme are smaller than the Loopwheels Classics and Loopwheels Carbon, and so are no larger than the hubs on a standard spoked wheel.
  • Can Natural Fit push/hand rims be fitted to a loopwheel?

    It is possible to fit Natural fit pushrims to 24" loopwheels (6 riv-nut version only), just not 25" loopwheels as the rim sizes are not compatible. We don’t stock Natural Fit pushrims but you can order loopwheels without pushrims.  
  • What are my pushrim options?

    We are the UK distributor for CarboLife, a German brand of ergonomic hand rims that are designed to optimise comfort for a number of hand functions. We are also able to supply Tetra Gripp pushrims to fit Loopwheels. Please visit our product page for more information, or email [email protected] if you require a rim that we do not advertise.
