State-of-the-Art Wheelchair Electric Motor Unit:
More Powerful and Easier to Use
Key Features
- Ample Power for Every Situation
- The drive unit’s performance has been significantly enhanced and the JWG-1’s ample power can be felt when on inclines, going over uneven surfaces, and even unpaved roads. Maximum load capacity has also been increased from 125 kg to 160 kg.
- Lightweight Battery for Easy Portability
- The JWG-1 features a lighter and more compact battery, going from the previous version’s 3.6 kg to 2.4 kg. This makes detaching and reattaching it for charging, as well as carrying a spare battery, much easier. The charger unit itself is also compact.
- Easy-to-View LCD Screen
- The control panel screen is approx. 1.7 times larger and its design minimizes blockage of the screen by the hands, making the information shown easier to see. It also features a high-output USB port capable of charging smartphones and other devices.
- Confidence and Control on Downhill Slopes
- Returning the joystick to the center engages an electromagnetic brake that boosts user confidence when descending slopes and inclines. In addition, detailed adjustments to the unit’s speed, sensitivity, and other settings can be made with the dedicated Smart Tune software.
- Yamaha’s Proprietary Wheelchair Travel Control System -
Various control technologies at the ready with the joystick and now even easier to operate.
- Speed Control
- The unit’s maximum speed can be adjusted to suit the user’s individual ability or preference.
- Joystick Sensitivity Control
- For example, selecting “Narrow” allows the unit to operate at maximum speed even with minimal joystick movement.
- Acceleration Control
- The distance it takes to reach maximum speed can be adjusted to be shorter or longer as preferred.
- Joystick Direction Control
- The direction for joystick inputs (forward, backward, left, and right) can be reversed as desired, such as pushing the joystick forward to move the wheelchair backwards.
- Deceleration Control
- The time it takes to come to a stop can be adjusted, enabling more gradual deceleration if desired.
— Dedicated Tuning Software —
The dedicated JW Smart Tune software allows the wheelchair user to adjust the power unit settings to suit their physical condition and typical usage. Changes to the settings should be made at your local authorized Yamaha dealership and based on expert guidance from a physical therapist or occupational therapist.
Speed and Acceleration
For example…
- • I want acceleration to be slow when moving forward
- • I want to be able to change direction a little faster
Joystick Sensitivity
For example…
- • I want to change the joystick angle for maximum speed
- • I want the joystick to not respond from small hand trembles
Joystick Direction Control
For example…
- • I want to change the direction for the joystick when reversing
- JW Smart Tune Is the Solution!
- Speed, acceleration/deceleration, joystick sensitivity/direction, and more can be tailored to best fit the individual user.
Convenient Features (Optional Accessories)
- Slide Bracket
- This allows the arm with the joystick and display to slide, making it easier to move the wheelchair closer to desks and the like.
- Custom Joystick
- The joystick can be modified to better facilitate operation for users.
- Assist Controller
- This aids assistants when going up or down slopes or for longer outings. This also allows the wheelchair to turn in place, making getting in or out of more confined spaces simple.
- Charging Cable
- This allows the battery to be charged while still attached to the wheelchair.

- *1
- Measured according to ISO 7176-4: 2008 (24-inch wheels, new fully charged battery, and ambient temperature of 18-25°C, weight 100 kg)
- *2
- The JWG-1 unit can withstand a load of 160 kg (including the rider, luggage, and frame weight).
However, confirm the detailed specifications, including the frame strength, with the wheelchair manufacturer.
- *3
- This is the value when adjusted under the following conditions
• With the casters and rear tires touching the ground, and the auxiliary wheels on the end of the anti-tip bars at a height of 35 to 50 mm from the ground
• With a distance of 245 mm or more from the back pipe to the center of the auxiliary wheels on the end of the anti-tip bars The maximum safe slope angle specified by the wheelchair manufacturer takes precedence, so be sure to check with the manu-facturer.
- *4
- This is the available temperature range. Confirm the recommended temperatures for "6. Characteristics and handling"
