Go the distance with a removable battery

Traditional power assist devices often feature non-removable batteries, limiting your range and freedom while requiring downtime when the batteries need to be replaced. The R90's standard battery has a range of up to 9.8 miles*, and the extended battery has a range of up to 19.5 miles*. Take a second battery with you to go even further. Remove the battery to lighten the R90 when carrying or transporting it.

The standard battery (2.5 Ah) meets current regulations to be carried on a plane (always verify with your airline for current regulations).

* Range is dependent on the ground surface, the weight of the user, driving behavior, temperature, and terrain.

Wheel up function

No need to be a drag

When the R90 is not needed, raise the wheel for zero rolling resistance. This can be done with a button on the Control Box or from the Sunrise Intelligence app. Even though the R90 is easy to remove, you can just raise the wheel and keep it on your chair all day long.

Durable tire

Push-button propelling

Drive your chair easily without a strong grasp or dexterity. Start and control your speed with the push of a button. Free up your hands to steer and stop, push a cart, or hold the hand of a loved one.

The wireless Control Box can be mounted on your wheelchair's frame anywhere convenient to you.
Raise or lower the wheel any time.
Set your speed for any situation – dialed down in a crowded store or ramped up to keep up with your dog. You have a maximum speed of 5.5 mph!
To get moving, simply press the plus (+) button. Or, you can propel to the speed you want and press the plus (+) button to maintain it, like cruise control.

There's no learning curve; just faster, slower, wheel up, or GO!

Bluetooth

The Control Box connects to the R90 via Bluetooth^®, so there aren't any cables to get in your way. Regardless of your location and movements, Bluetooth stays reliably connected. The Control Box can be quickly removed to help with transfers or to avoid damage during air travel.

V-LOCK

Simple, secure attachment

The patent-pending V-LOCK^™ is a tapered latch that securely docks the R90 to the receiver on the chair. Combined with the ergonomic, easy-grasp handle; upright orientation; and rolling tire, the R90 can be attached by many people while they are seated in their chair.

Reimagine your ride with the Empulse R90, designed to fit most rigid and folding wheelchairs. A durable yet lightweight bracket is fastened to the chair and remains on the chair while the R90 can be easily detached.

Rigid and folding wheelchair compatibility

Drive performance

The compact design of the R90 offers great handling, agile turning, and stability. The R90 was designed for uncompromising performance, extended range, and ease of use, so riders can commute to work or school (without arriving sweaty), run errands, or take longer trips.

Center spin

The R90 drive wheel is positioned under your seat. This means you can maneuver forward, backward, and 360° with minimal drag or hang-up. In tight spaces, move as you normally do. Getting into and out of tight spaces is just as easy with the R90 mounted, raised, or removed, as it doesn't extend beyond your rear wheels. The center spin of the tire allows for precision turning. No fishtailing, no rear bounce. It moves like it's a part of you.
One-hand speed control

To maintain your speed, go faster, or slow down, simply push a button on the easy-to-access Control Box. This frees up one of your hands for more important things, like coffee.

Compatibility

The Empulse R90 is compatible with most rigid and folding wheelchairs. The reciever brackets don't interfere with chair components, and still allow folding chairs to fold.

Empulse R90 rigid wheelchair reciever bracket

For rigid chairs, the receiver bracket mounts directly to the camber tube and can remain in place, whether the R90 is on or off your chair.

Empulse R90 folding wheelchair reciever bracket and crossbar

For folding chairs, the assembly has a sturdy crossbar that is spring-loaded for quick installation and removal.

See R90 brochure for exact measurements.

Sunrise Intelligence App

Use the app during the initial setup of the R90 to optimize its performance to the rider's weight and wheelchair. The R90 App allows you to select the performance profile and maximum speed that best suits your environment, whether you are indoors or outside. The preset drive profiles are tailored for specific environments for speed, torque, and slope thresholds.

The app shows battery charge, so you always know when you need to recharge. You can raise or lower the R90's wheel and check the position of the wheel from the app. Historical data is shown in a dashboard so you can track your maximum speed and distance. The app is compatible with Android^™ and Apple^® iOS.

"I've been a wheelchair user for 20+ years now. Maintaining my shoulder health is a top priority in order to continue an active and social lifestyle. Whether it's at the office, an outdoor concert, grocery store, or airport, the R90 helps me alleviate shoulder stress so I can complete everyday tasks, as well as enjoy activities and social events with friends."

Mike T., T-4 SCI, 20 years post-injury

"I remember going up this long ramp at the Dallas VA, and I was amazed at how effortlessly the R90 kept up its speed. It really made a difference for me. Plus, knowing I have a backup battery for those extra-long days gives me peace of mind. It's definitely going to save wear and tear on my shoulders."

Bob S., L-1 SCI, 46 years post-injury

"A big positive about the R90 is how fast I could start using it. The control box is easy to understand and learn out of the box. I was having a lot of difficulty with shoulder pain, and the R90 helped me overcome it. I will always use the R90 for this reason. It still feels like my chair – just more power!"

Frequently Asked Questions

How far can I go with the Empulse R90?

Standard battery: up to 9.8 miles (15.7 km)
Extended range battery: up to 19.5 miles (31.4 km)

Range is dependent on the ground surface, the weight of the user, driving behavior, temperature, and terrain.

How fast can I go with the Empulse R90?

Drive smart with the extra power unit for your wheelchair!

Maximum speed forward is 8.9 kph (5.5 mph).

Using the Empulse R90 with maximum speed settings higher than 6 kph (3.7 mph) is only permitted on public roads in certain countries and otherwise may only be used on private property.

In the absence of approval (attached to the Order Form and must be signed before ordering), in accordance with the road traffic laws, the Empulse R90 with speed >6 kph may not be driven on public roads, bicycle-lanes, and pavements. You need to inform yourself about the country-specific legislation regarding usage and it is your legal obligation to ensure the Empulse R90 speed can be set up higher than 6 kph. When you're traveling with your Empulse R90, always check the specific legislation in the respective country.

How can I attach the Empulse R90?

The patent-pending V-LOCK^™ is a tapered latch that securely docks the Empulse R90 to the receiver on the wheelchair. Combined with the ergonomic & easy-to-grasp handle, upright orientation, and rolling tire, the Empulse R90 can be attached easily and securely. For some, this can be done while seated in their wheelchair.

How do you store the battery correctly (e.g. over winter)?

Store the battery in a dry, cool place at around 50° F (10° C) to 77° F (25° C). It is recommended to keep the battery at a state of charge of approximately 75%. If it is stored for too long with low charge, the voltage inside drops significantly and a deep discharge can occur, which could permanently damage the battery. Therefore, charge the battery every 12 weeks when stored.

How long does it take to charge the Empulse R90?

Charging the R90 device could take 1 hour for the Standard battery (2.5Ah) and 2 hours for the extended battery (5Ah).
