The Klaxon Twist Wheelchair Power Assist redefines powered mobility with one compact system that can push from behind, pull from the front, or operate with an optional foldable handlebar. Designed for compatible rigid and folding manual wheelchairs, Twist provides adaptable assistance for tight indoor spaces, longer outdoor trips, hills, and varied terrain.
Unlike power-assist accessories limited to a single mounting position, Twist transitions between rear and front configurations at ground level, eliminating the need to lift the 18.5-pound drive hub during conversion. The patented Linking System Klaxon® supports front and rear attachment and provides an audible latch confirmation when the connection is secured.
Powered by a 700-watt motor and removable 36V, 144Wh lithium-ion battery, Twist delivers a maximum range of up to 12 miles under specified conditions. Standard front- and rear-mounted configurations reach speeds up to 6 mph, while the optional handlebar configuration can reach up to 9 mph after app-based opt-in.
Three Versatile Driving Configurations
Rear-Mounted Push Assist
The compact rear position is ideal for homes, offices, schools, restaurants, public transportation, and other confined environments. Twist pushes the wheelchair from behind while allowing the user to steer, slow, and stop through the handrims.
Front-Mounted Pull Assist
Moving Twist to the front raises the wheelchair’s front casters, increasing ground clearance and creating a smoother ride across appropriate outdoor terrain. This configuration supports longer distances, improved obstacle clearance, motor braking, and controlled downhill travel.
Front Mount with Optional Folding Handlebar
Adding the optional handlebar provides direct steering, a mechanical disc brake, and increased control for longer rides and varied terrain. Standard speed is 6 mph, with an optional 9 mph setting available through the Klaxon app. Reverse speed is limited to 3 mph.
Adaptive Drive Control
Twist’s Adaptive Drive Control responds to the way the wheelchair user interacts with the handrims. Set the desired speed, and the motor supplies power to maintain that pace. When resistance is applied at the rims to steer, slow, or stop, Twist reduces motor output. As the resistance is released, the system gradually accelerates back toward the selected speed.
Acceleration, top speed, braking response, and motor sensitivity can be programmed to match the user’s abilities, preferences, and environment. Twist can also be preconfigured before delivery using settings selected during the quotation or ordering process.
Climb and Downhill Assistance
When ascending an incline, Climb Assist Mode supports a more consistent driving experience. Adaptive speed behavior can be re-engaged with a button on the standard Multi-Function Controller.
In the front-mounted configuration, Twist provides controlled downhill assistance and electronic motor braking. Braking capabilities vary by attachment setup, and the optional handlebar adds a mechanical disc brake for direct stopping control.
Foldable Handlebar for Travel and Storage
The optional Klaxon Folding Handlebar attaches without tools and folds in seconds. Its lightweight 5.3-pound design adds steering stability and direct braking control while remaining compact enough for convenient storage in a compatible carry bag.
When the handlebar is not needed, it can be removed and stowed while Twist returns to its rear- or front-mounted configuration.
Personalized Control with the Klaxon App
Bluetooth and Wi-Fi connectivity allow the Klaxon App to personalize the Twist driving experience. Users and qualified providers can adjust speed, power, braking, acceleration, and motor sensitivity while viewing real-time usage and battery information.
The app also provides access to the optional 9 mph handlebar speed setting. Configuration should reflect the user’s abilities, environment, applicable regulations, and professional recommendations.
Built for Compatible Folding and Rigid Wheelchairs
Twist supports compatible manual wheelchairs with seat widths from 12 to 20 inches and rear wheel sizes of 22, 24, 25, or 26 inches. It works with both folding and rigid frames and has no published chair-depth restriction.
