INTRODUCING BOUNDER Power Wheelchairs by 21st Century Scientific, Inc.
with speeds up to 11.6 MPH

BOUNDER Plus H-Frame

High Performance

Using a wheelchair full time doesn’t mean trailing behind. The days of forcing others to wait for you to catch up in a slow power chair are over once you drive a BOUNDER! Speed when you need it, accurate control all the time. Don’t settle for less! Add some fun back into your life. Do people buy fast cars because they need to go over 100 mph? Well not really, BUT it is FUN. Do people buy cars that won’t accelerate to freeway speeds? Not if they have to drive on freeways. So don’t accept a power wheelchair that can’t keep up with the rest of the world!

You may not need to drive 11.6 MPH all the time, but there are times when you need a fast power chair. For example, when crossing large intersections and the light turns red - if you were walking, you would run. If you are in a high speed BOUNDER Power Chair, you could use the extra speed to safely get across the street before the traffic was upon you. Do you need to traverse a large campus? College students and employees of large businesses located on a campus will appreciate the speed provided by the BOUNDER Power Wheelchair to arrive on time for class or a meeting. Go to the store or visit a friend and cut your travel time by half or more! And have some FUN too.

Did you think that you can no longer play sports? Not only does the BOUNDER help you excel in power hockey, power soccer and tennis, but also select models can allow you to enjoy regular sports such as golf, dog agility, etc.  The high speed BOUNDER will give you an edge on the competition. It will enable you to enjoy many activities that you thought were no longer available.


Wheelchair Top Speed Comparison Chart

Don’t be fooled by false claims. Many wheelchair users have boasted to us that they have very fast chairs. But when put to the test, the high performance BOUNDER Power Wheelchair leaves them in the dust.


Fast! BOUNDERS can be configured for 9.1, 10.0, 10.8 or 11.6 mph top speed. Standard Super Torque 3 Motors provide not only fast speeds, but also smooth quiet operation. Don’t really want to go super fast? Slower speeds are easily programmed.

Electronics: Programmable UE1G electronics provide 6 drive choices and a battery condition meter.
Extended Range! Don’t get caught with insufficient range to get through your day. Our large, sliding dual group 27 battery box* provides more range than most users will need in a day - up to 40 miles per charge under ideal conditions and over 25 miles per charge in typical use. The heavy duty slides on this battery box make maintenance easy.
*Group 27 batteries are the largest in use on power wheelchairs and are readily available.
H-Frame Base: Uses 2.5”x1.5”x0.125” wall steel and is TIG welded for uncompromising strength and durability.
Adjustable Suspension Forks: Made of 1/4” thick steel and utilizing a 1” diameter stem, provide impact dampening in the front of the chair as well as seat tilt adjustment.
Wheels: 9” x 3.50” front casters and 12.75” x 4.00” drive wheels are standard. Drive tires are available in either a smooth or knobby tread.
Standard “Extras”: Built-in taillights turn on and off with chair power for added safety. A smart electric brake release switch offers easy pushing of the chair by an attendant.
Seating Systems: Enjoy the power seating system that meets your needs. Options include power seat elevator with 13” of elevation, power standing, power recline, power tilt, and dual independent power elevating legrests. All power seating systems can be proportionally controlled through-the-joystick as an available option.
