Edge 3 Stretto

MDR Class I (2017/745/EU) Medical Device

A narrow width for outstanding manoeuvrability

Power chairs are known for their extended range and often sacrifice manoeuvrability due to their excessive width, making them challenging to navigate in tight spaces at home or on the go.

The Quantum Edge 3 Stretto power chair overcomes these challenges. It is one of the narrowest and most manoeuvrable power chairs currently available, with a maximum overall width of just 520mm (20.5 inches) while retaining the comfort and features of a full-size chair. Alongside its narrow build, the Quantum Edge 3 Stretto power chair boasts a mid-wheel drive design with castors in each corner, enabling it to turn effortlessly within its own space. This makes the Stretto the ideal wheelchair for children, teenagers, and smaller adults, complementing the standard Quantum Edge 3 power chair, offering similar features in a more compact size. It is available with either 2 x 62Ah or 2 x 40Ah batteries, depending on the inclusion of power positioning.

A versatile model

Equipped with an independent Smooth Ride Suspension (SRS) system featuring a coil-over design, it optimises shock absorption by adjusting the angle of the shocks. This setup ensures a smooth ride with soft, comfortable springs while maintaining stability and drivability. The coil-over arrangement neatly integrates the shock absorber and spring for enhanced control.

With a maximum ground clearance of 73.6mm (2.9 inches) and the ability to overcome obstacles up to 89mm (3.5 inches) high, the Quantum Stretto power chair is well-suited for navigating various everyday environments. It operates at a top speed of 4mph, offering mobility in diverse situations. Additionally, opting for the optional 62Ah batteries increases the maximum speed to 6mph, extending the Quantum Stretto power chair's range even further.

The Quantum Edge 3 Stretto power chair offers superb manoeuvrability indoors and is fully capable outdoors as well.

Customisable features

Quantum Rehab Edge 3 Stretto mobility chair offers a range of customisable features, including our iLevel system. This innovative technology allows for seamless adjustment of seat height while the chair moves at a walking pace, providing flexibility in your working height without the need for frequent stops and starts. With the iLevel option, users can enjoy up to 12 inches of power-adjustable seat elevation at a top speed of 3.5mph.

Further personalisation options cater to individual preferences with the Quantum Edge 3 Stretto power chair. Choices include the standard 12-inch drive wheels being upgraded for the 14-inch alternative and the choice of pneumatic or solid knobbly tyres – all the better for rough outdoor terrains. The Edge 3 Stretto power chair comes in 14 vibrant colours, which can be applied to the power base, seat fittings, and wheel centres.

Standard features for safety and convenience on the Quantum Stretto power chair include front and rear LED fender lights, allowing you to see and be seen. Additionally, the USB charging port allows you to power your other devices. The intelligent braking system captures energy to regenerate the batteries, while a disc brake secures the power chair when parked. There are also integral tie-down points on the power base for securing the power chair when in transit in a wheelchair-accessible vehicle.
