Empulse F35 vs Empulse R90: Which Wheelchair Power Assist Is Right for You?

If you're looking for a powered add-on for your manual wheelchair, two of the most popular options are the Empulse F35 and the Empulse R90. Both are designed to make everyday travel easier by reducing the effort needed to propel your wheelchair, but they work in different ways and suit different lifestyles.

In this guide, we'll compare the two systems to help you decide which one best fits your needs.

Empulse F35

The Empulse F35 is a front-mounted pull device that connects to the front of your manual wheelchair. Once attached, it lifts the front castors slightly off the ground and pulls you forward using a handlebar throttle.

This design makes it feel similar to riding a compact powered scooter while still using your own wheelchair. The F35 is lightweight, compact and easy to attach with its one-motion docking system. It is particularly well suited to users who want higher speeds and a little more confidence on longer journeys.

Advantages

  • Higher travelling speeds.

  • Comfortable handlebar steering.

  • Excellent for longer outdoor journeys.

  • Lightweight and compact for transport.

  • Quick attachment and removal.

  • Great for commuting and leisure outings.

Things to Consider

Because the drive unit sits in front of the wheelchair, it increases the overall length of the chair. While it's still highly manoeuvrable, it may be slightly less convenient in very tight indoor spaces.

Empulse R90

The Empulse R90 is a rear-mounted push assist that fits neatly underneath your wheelchair without increasing its overall size or turning circle.

Rather than pulling you from the front, it provides powered assistance from behind while you continue steering using your wheelchair's push rims. The drive wheel can also be retracted when assistance isn't needed, allowing you to switch easily between powered and manual propulsion. It also offers a longer maximum range with its extended battery option.

Advantages

  • Maintains your wheelchair's natural handling.

  • Doesn't increase the chair's length.

  • Longer battery range available.

  • Very lightweight.

  • Excellent for shopping, commuting and everyday use.

  • Retractable drive wheel.

  • Smartphone app for personalised driving profiles.

Things to Consider

The R90 relies on steering with your wheelchair's push rims, so users should be comfortable controlling and stopping a manual wheelchair while using powered assistance.

Which One Is Better?

The answer depends on how and where you use your wheelchair.

Choose the Empulse F35 if you:

  • Want higher travelling speeds.

  • Spend lots of time outdoors.

  • Enjoy longer journeys.

  • Prefer handlebar steering.

  • Need a compact front-mounted solution.

Choose the Empulse R90 if you:

  • Want to keep your wheelchair's original handling.

  • Mainly travel around towns, shops and indoor environments.

  • Want the option to switch between manual and powered propulsion.

  • Need maximum battery range.

  • Prefer a discreet system that remains fitted underneath your chair.
