Quick Response

Emergencies don’t come with warnings, which is why speed matters most. Assist Lite is designed to be deployed in seconds, so there’s no fumbling, waiting, or complicated setup when every moment counts. Whether it’s helping a child, elderly parent, or patient during an urgent situation, you can trust that it’s ready the moment you need it.

Battery built for emergencies

Long-Lasting Power

The quick-release lithium battery isn’t just fast to charge it’s built to last when situations demand reliability. Fully recharged in just 2.5 hours, it powers up to 40 floors on a single cycle. That means even in prolonged use, you’ll have dependable performance without worrying about losing power mid-climb. It’s one less thing to think about when safety is on the line.

Secure every step

Safe Ride

Assist Lite was designed with safety as its foundation. A four-point aircraft seat belt secures the rider in place, independent rear brakes lock the unit when stationary, and durable tracks grip stairs with confidence. For caregivers, that means every trip up or down feels controlled and stable. For riders, it means peace of mind knowing they’re safe at all times.

Tested for tough moments

Real Assurance

With its 200W brushless motor, quick-release battery, and fold-out emergency handle, Assist Lite gives caregivers full command even when power or time is limited. Unlike bulky alternatives, it’s engineered for both strength and adaptability, ensuring you can guide loved ones smoothly through staircases of varying heights or angles without uncertainty.

FREQUENTLY ASKED QUESTIONS

Who is the Assist Lite designed for?

The Assist Lite is built for emergency mobility scenarios, especially for children, elderly individuals, or persons needing assistance in outdoor or evacuation settings. It’s compact and lightweight ideal for caregivers, schools, public institutions, and families.

What’s included in the box?

Each purchase includes:

  • 1x Assist Lite unit
  • 1x Quick-Release Lithium Battery (36V / 5Ah)
  • 1x Charger
  • 1x Removable Seat Cushion
  • 1x Emergency Manual Handle
  • 1x User Manual

How do I know when to charge the battery?

There’s a built-in battery indicator on the control panel so you can monitor usage and avoid running low during operation.

Does it need a special operator or license?

No. The controls are simple, color-coded push buttons — making it intuitive to operate by trained caregivers, family members, or emergency responders. However, a brief orientation or manual review is recommended before use.

How steep of a staircase can it climb?

It can safely climb stairs with an angle of up to 35°, which covers most standard residential and commercial staircases.

How long does the battery last on a single charge?

On a full charge, the battery lasts for approximately 0.5 hours or up to 40 floors of stair climbing. The 36V / 5Ah lithium battery can be fully recharged in 2.5 hours.

How much weight can it safely carry?

The Assist Lite supports up to 120 kg (264.5 lbs) of body weight. Always ensure the passenger is securely fastened with the four-point seatbelt.

Can it be used without power?

Yes. Assist Lite is equipped with a manual emergency handle, allowing operation even when power is unavailable.

Is it noisy when climbing?

Nope. The motor operates below 70 decibels, which is about as loud as a quiet office. Perfect for schools, clinics, and quiet residential settings.

What are the dimensions of the Assist Lite?

  • Unfolded: 57”L × 19.7”W × 46.5”H
  • Folded: 39.4”L × 19.7”W × 11.8”H
  • Seat Height (from ground): 18.8”
  • Track Length: 29.1”
  • Weight: 39.7 lbs

What is the size of the Assist Lite?

The Assist Lite is compact and portable perfect for emergency or home use:

  • Unfolded Size: 1450 × 500 × 1180 mm (57 × 19.7 × 46.5 inches)
  • Folded Size: 1000 × 500 × 300 mm (39.4 × 19.7 × 11.8 inches)
  • Packaging Size: 1050 × 560 × 330 mm (41.3 × 22 × 13 inches)

It’s easy to store, transport, or fit in tight spaces like stairwells, hallways, or vehicle trunks.

What types of stairs can it handle?

Straight stairs made of concrete, tile, wood, or carpet (with moderate thickness). Not compatible with spiral, curved, or very narrow stairs.

How hard is it to learn?

Not hard at all. Both units have simple fixed-speed controls. Most caregivers master it in under 30 minutes. We also provide a step-by-step manual.

Can I use this alone as a caregiver?

Absolutely. With a little practice, most users (including older or smaller-frame caregivers) can operate either model safely solo. We recommend doing a few practice runs first, without a person in the chair.
