Fitting

  • Do loopwheels fit any wheelchair?

    Loopwheels fit most ACTIVE MANUAL ADULT wheelchairs, ie those with 24" or 25" wheels.
  • Will I need to buy new axle pins?

    Your old axle pins will usually fit your new loopwheels, or may need a minor adjustment.  You can buy new ones from us if your existing axles don’t fit or if you want a second pair. Our range includes both ½” (12.7mm) and 12mm width axles, in 99mm, 104mm, 109mm and 120mm lengths  - so we’ve got a wide selection if you need it. Quick release axle pins are adjustable by up to 4mm in either direction.
  • Which length axle pin is right for my chair?

    We've 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 stock 99mm, 104mm,109mm and 120mm lengths, and may be able to obtain other alternatives too. Each axle length is adjustable at the head up to about 8mm (4mm in either direction). We also supply 2 metal spacers with each axle (and a rubber grip) in case minor adjustments are needed.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.
  • Is there a minimum and maximum weight limit?

    Yes. Each wheel we've developed has been optimised for different weights and applications. The maximum weight covered by the warranty is shown in the user manual. Our warrantied load limit for wheelchair wheels is 120kg. The load is the weight of the rider plus the weight of everything else carried on the wheels. This is in line with the 100kg user weight limit on most active manual chairs. 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.    
  • 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
  • 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.
  • 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. We fix the bearings into the wheel hub with a high specification 'Loctite' bond. If you need to change bearings, please seek advice from us at [email protected], or talk to your local dealer.  
  • 12mm or ½ inch diameter bearings?

    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 are unsure about the diameter of bearings please 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, Or ask us for advice at [email protected]  
  • What clearance do I need between a sideguard and my loopwheel?

    Allow a gap of at least 30mm between the sideguard and your Loopwheel. The integral suspension technology needs room to move so with insufficient clearance, the wheel could brake when it comes into contact with the guard. It may be possible for your guard height to be adjusted. Check before fitting the loopwheels to your chair!

  • Are loopwheels wider than a standard spoked wheel?

    All Loopwheels are designed for the tyre to sit slightly further out from the chair than a Spinergy wheel, to allow for the suspension movement. The push rims will also be slightly further out than on a Spinergy wheel. Loopwheel Classic and Loopwheel Carbon have the same width at the centre of the hub as a standard spoked wheel.  However, the wheel is 7mm wider 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 the same size as the hubs on a standard spoked wheel.  

General

  • How much does a Loopwheel weigh?

    Loopwheels are slightly heavier than wheels with conventional spokes. But for this, you get suspension as well as a wheel! The weights without tyres or push rims are:
    • Loopwheels Urban (24"): 1.36kg
    • Loopwheel Extreme:1.33kg
    • Loopwheels Classic (24") : 1.84kg
    • Loopwheels Carbon (24"): 1.84kg
    • Loopwheels Classic (25"): 1.86kg
  • Is there a speed limit for Loopwheels?

    Yes. For Loopwheels Classic and Carbon, the warrantied speed limit is 7km/h (4.35mph). Classic and Carbon are only suitable for manual use or with a power attachment at low speed. For Loopwheels Urban and Extreme, the warrantied speed limit is 25km/h (15.5 mph).
  • 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 actually travels 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.
  • Is the suspension on loopwheels adjustable?

    No. 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. The Loopwheels Urban has three different spring rates (soft, regular and stiff) and the Loopwheels Extreme has two (regular and stiff). Your choice will depend on the average speed of travel, user weight and personal preference. The Regular spring rate of the Loopwheels Urban and Extreme are the same compression as Loopwheels Classic. Please get in touch with us via [email protected] if you have questions about the differences in spring rates.
  • Can I change the colour of my loopwheels?

    Loopwheels Classics are available in Black, Purple, White, Blue, Green, Red and Orange. You can choose to mix these colours around the wheel too. The springs are integral to the structure of the wheel and therefore cannot be changed once they have been made. The Loopwheels Carbon, Loopwheels Urban and Loopwheels Extreme have a carbon finish, with reflective logos built into the spring coating.
  • Do loopwheels require any maintenance?

    Loopwheels require very little maintenance other than an occasional clean. We advise you wash your wheels with warm soapy water if required – avoid aggressive abrasive cleaning agents. Check your wheels and chair regularly for wear and to spot any early signs of damage - see our user manuals for recommendations.
  • Where can I buy loopwheels?

    You can buy direct from us via the "products" page on this website, or by contacting us on [email protected]. Or check out our stockists page if you would like more personal service or wish to buy Loopwheels as part of a whole chair solution. In some countries we have an arrangement for exclusive supply through a distributor and don't sell direct from our website. In this case your country won't come up in our list of shipping destinations. Contact the distributor for your country shown on our stockists page and they will direct you to a supplier local to you.
  • What's the difference between types of Loopwheel?

    Click on our comparison chart for a summary of all our wheels.  
  • How bouncy or stiff are Loopwheels?

    Loopwheels are actually quite stiff!
    The loops are made of composite materials 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 have one spring stiffness. Loopwheels Urban comes in three spring rates: Soft, Regular and Stiff. Loopwheels Extreme is available in two spring rates: Regular and Stiff. Please visit your local stockist to try the selection of spring rates or contact [email protected] for more information. In the UK, you can try before you buy for just £20.
  • How do Loopwheels compare with spoked wheels?

    Spokes or Loops?
  • Why are some products VAT exempt? When do you charge VAT?

    In the UK, there is a zero rate of VAT for products designed for people with disability and bought for their use. We have to ask you to make a declaration if you believe you qualify for this exemption, according to HMRC rules. All push rims and Loopwheels for wheelchairs are VAT exempt. If you aren't exempt, VAT will be added in the usual way for UK sales. Export (sales from the UK to countries outside the UK). If you are buying from outside the UK, we don't charge VAT. But you may have to pay your own country's taxes or import duty to the delivery courier when they deliver your goods.  
  • 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. Children and adults of lighter weights may not feel the full benefit of loopwheels suspension except when you hit a bump with real force, although there will still be some vibration reduction. Our best option for lighter weight people is the Loopwheels Urban with Soft springs.
       

Hand rims

  • What are my pushrim options?

    Loopwheels come with a black powder-coated aluminium push rim. Or you can upgrade to one of a wide choice of ergonomic hand rims that are designed to optimise comfort for a number of hand functions. Please visit our product page for more information, or email [email protected] if you require a rim that we do not advertise.
  • Can Natural Fit push/hand rims be fitted to a loopwheel?

    It is possible to fit a 6 rivnut version of the Natural Fit pushrims to 24" loopwheels. It's not possible for 25" Loopwheels. We don’t stock Natural Fit pushrims but you can order loopwheels without pushrims. We have a wide range of alternative, ergonomic hand rims.  

Mountain Bike

  • Do you make bike and MTB wheels?

    We currently only make wheels for wheelchairs. If you want a MTB tyre on your wheelchair, we recommend our Loopwheels Extreme.

Tyres

  • Can I fit solid tyres to my loopwheels?

    We don't recommend solid tyres to be used with Loopwheels due to the amount of wear and tear they inflict on the wheels (and on your body!). Your wheel warranty is valid for Loopwheels fitted with pneumatic tyres only.
  • What size tyres fit my loopwheels?

    We recommend Schwalbe Marathon Plus wheelchair tyres. It's 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, specifically designed for wheelchairs. If you would like to purchase your own tyres you will need to know the ETRTO number (a standard international tyre coding): 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)   You may be asked for the  BSD (Bead Seat Diameter) of your wheels. For 24" Loopwheels Classic, 24" Carbon and 24" Loopwheels Urban, the BSD is 540mm For 25" Loopwheels Classic and Carbon, the BSD is 559mm For Loopwheels Extreme, the BSD is 507mm    
  • What tyre pressure do you recommend for Schwalbe Marathon Plus on Loopwheels?

    Keep your tyres well pumped up as soft tyres require more effort to push and the tyres wear out more quickly. The recommended pressure for all Schwalbe tyres is marked on the sidewall of the tyre.  On our Loopwheels Classics, Carbons and Urbans, it's 6.00 - 10.00 Bar (85 - 145 psi) and we recommend 90 -110 psi. For the Extreme, the range is 45-70 psi and we recommend 60 psi. But personal preferences may vary.
  • Can I add a deeper tyre to a 24" Urban wheel to make it bigger?

    Yes, if you want to make your overall wheel bigger than 24", choose a Schwalbe Marathon Plus ETRTO 37-540 (24 x 1 3/8) instead of ETRTO 25-540 (24 x 1)
