Invacare TDX SP2 HD

The Invacare TDX SP2 is a robustly engineered configurable powerchair ideal for those after a solid outdoor performer that can also be used inside too. With a range of seating options, including both Invacare's Modulite and Max seating ranges, the TDX SP2 HD can cater for wheelchair users up to 28 stone, while a Low Rider option allows extremely low seat heights.

Product Description

Power base

While wider than the narrow wheelbase "NB" version of the TDX SP2, the TDX SP2 HD variant still has mid-wheel drive, allowing it to turn on the spot, as well as offering greater stability outdoors along with the automatic Stability Lock system. Patented SureStep technology ensures that all six wheels remain on the ground at all time, giving fantastic performance outdoors, complemented by the full suspension.The powerful motors can be upgraded to a 6 or 8 mph speed if required.


The full range of Invacare's Modulite seating system can be fitted, giving postural support and comfort that can be set up to the needs of any user. It is also available with Invacare's Max seating range, with seat widths of up to 24 inches possible. A weight capacity of 28 stone applies to all seating options. The full complement of powered options that one would expect on such a high-end wheelchair are available, including powered lift, tilt, recline and powered elevating legrests. The modular nature of the wheelchair also allows adjustment at a later date, should your requirements change.

Additionally, a Teens Modulite version is available for younger users, in seat widths of 12 - 15" and depths of 12 - 22", to accommodate the body shape of adolescents - although generally the increased manoeuvrability of the Narrow Base version is more appropriate for younger users.

The Low Rider variant has an ultra-low seat height of either 403mm or 420mm. This allows easy access under desks and tables, although it should be noted that the weight capacity is reduced to 25 stone (160 kg). This model is best suited to shorter people who do not need longer leg-rest lengths.


Modern LinX controls are available on the TDX, which allow for easy expansion should your requirements change in the future, as well as advanced controls such as the REM400 touch-screen joystick module.


The TDX range has been refreshed with a stylish new look, including a choice of 10 shroud colours and 10 wheel insert colours, given you 100 possible colour combinations for your chair.

Our verdict

Ideal for those that require a top performing wheelchair primarily for outdoor use, but also for some inside use, the TDX SP2 is especially suited for people after a wheelchair that can be set up exactly to their requirements, and which can also be adapted at a later date should their needs change. While most people will find the NB version works better for them, due to its narrower base, for heavier people or those making more demanding journeys outdoors, the standard TDX SP2 is likely to work better.

If you are looking for a high-performing outdoor mid-wheel drive powerchair, we would suggest trying the TDX SP2 HD alongside Quickie's Q700 M and Permobil's M5 Corpus. For true off-roading though, the Magic Mobility Magic 360 is a cut above the competition, albeit at a higher price point.

Prescriptive powerchairs such as this are built to order following an assessment with one of our Prescriptive Assessors. They are available with a wide range of customisation options, including powered seating functions, cushions and backrests, and drive performance upgrades, and these can affect the price - our Prescriptive Assessors will run through all the options at your assessment. As a general guideline, opting for multiple powered seating functions can add significantly to the cost of the wheelchair; however it is possible to get a fully functioning and desirable chair at the base price!

People purchasing powered wheelchairs will often qualify for zero-rated VAT. If the person using the wheelchair has a permanent disability, terminal illness or chronic sickness then they will be eligible for 0% VAT. Our Prescriptive Assessors will be able to answer any questions you may have about VAT.
