Wheelchair Power Assist Devices & Add-Ons

Transform your manual wheelchair into an effortless electric mobility system.


A wheelchair power add-on allows you to experience the motor-driven freedom of an electric wheelchair while continuing to use the exact manual frame you are already comfortable with. By substantially reducing upper-body strain, shoulder fatigue, and self-propelling friction, these modular systems make longer journeys, steep slopes, outdoor ramps, and uneven terrain fully accessible.

Frequently Asked Questions

Is my current wheelchair strong enough for a power add-on?


Most high-quality aluminum and steel manual chairs handle attachments comfortably. However, ultra-lightweight carbon fiber wheelchair frames can be susceptible to clamp stress. Our technician will explicitly verify your frame materials and weight limits during your free local evaluation to ensure absolute structural safety.

Will a power assist device work on a folding manual wheelchair?


Yes. While front-mounted handbikes and rear packs work natively with rigid frames, the manufacturers we work with design specialized universal crossbar adapters and quick-release configurations specifically for folding frames. This allows your chair to fold down flat for storage as normal once the power assist unit is unclipped.

Can I travel on an airplane with an electric power assist?


Most models in our lineup, including the Sunrise Medical Empulse F35 and Empulse R90, feature specialized lithium-ion batteries that are IATA (International Air Transport Association) certified. This means they are deemed airline-safe for commercial flights when checked or stored according to carrier rules.
