One-Arm Drive for Viper GT Wheelchair
External One-Arm Drive Conversion System for Drive Viper GT Wheelchair
Dual Concentric Handrim Control, Quick-Release Telescoping Axle Bar, Independent Rear-Wheel Steering, and Tool-Free Folding Frame Capability
For stroke survivors with hemiplegia, amputees, or individuals with severe single-arm weakness, self-propelling a standard manual wheelchair with one hand causes the chair to turn in circles instead of moving straight forward. The External One-Arm Drive System for the Drive Viper GT Wheelchair transforms a standard dual-handrim setup into an efficient single-sided propulsion mechanism, allowing full steering control and forward motion using only one arm.
Engineered specifically for the Drive DeVilbiss Viper GT wheelchair chassis, this external system features two concentric handrims mounted on the user's functional side. Pushing both handrims simultaneously drives the wheelchair straight ahead, while grasping the outer or inner handrim independently controls turning maneuvers. Connected across the rear frame by a heavy-duty, quick-release telescoping drive bar, the axle transfers mechanical force to the opposite wheel while collapsing smoothly so the wheelchair can still be folded flat for transport or storage.
Key Performance Features & Benefits
- Single-Arm Propulsion Control: Dual concentric handrims allow complete forward, backward, and turning control using only one arm.
- Viper GT Dedicated Frame Fit: Engineered specifically to mount cleanly onto the Drive Medical Viper GT lightweight wheelchair chassis.
- Quick-Release Telescoping Drive Bar: High-tensile cross-axle bar adjusts to seat width and unclips quickly to preserve wheelchair folding functions.
- Independent Dual-Wheel Steering: Pushing both handrims moves the chair straight ahead; pushing one handrim turns the chair smoothly.
- Left or Right Hand Customization: Available in dedicated Left-Hand or Right-Hand drive configurations to match the user's functional arm.
- Promotes Active Independence: Enables hemiplegic users and stroke survivors to self-propel without relying on caregiver pushing.
- 100% FSA / HSA Eligible: Qualified mechanical wheelchair propulsion conversion accessory eligible for pre-tax Flexible Spending Account and Health Savings Account reimbursement.
Mobility Specialist Insight: Single-arm drive systems are life-changing for hemiplegic stroke survivors who want to regain independent mobility. By placing two handrims on the functional sideāthe smaller outer handrim controls the opposite wheel while the larger inner handrim controls the drive-side wheelāthe user can steer and propel straight with one hand. When folding the Viper GT wheelchair for vehicle transport, simply press the quick-release spring buttons on the telescoping center bar to disconnect the drive linkage in seconds.

Frequently Asked Questions
Q: How do you steer a wheelchair using a one-arm drive system?
A: The system features two handrims on one side. Push both handrims together to move straight forward or backward. Push only the outer handrim to turn one direction, or push only the inner handrim to turn the opposite direction.
Q: Can the Viper GT wheelchair still be folded with this drive attached?
A: Yes. The telescoping center drive bar features a quick-release mechanism. Depressing the release pins disconnects the cross bar so the wheelchair can fold flat for car storage.
Q: Will this one-arm drive system fit other wheelchair models besides the Viper GT?
A: No. This specific drive assembly is custom-engineered to match the axle positioning, wheel hub geometry, and frame spacing of the Drive Viper GT wheelchair.
