      We did a little Smart drive demo video that day see it on our Facebook page Living Spinal fb
      Is the SmartDrive going to be at the Abilities Expo in San Jose this year? Will it work with a Tilite TR?

          I like it. But could a user put it together if you were driving a car instead of a van?

            In the video it appears the person put the battery pack on after unloading the chair ... I would be very interested in this. More so than the ZX-1 in fact if it's as light and portable as it seems.

            (Am I the only one noticing that the wheel housing reminds me of a dustbuster? lol)

              That's probably the biggest advantage of the SmartDrive. It is by far the easiest power add on to remove from the chair and load into a vehicle. The combined weight of the system is only 19 lbs. Took me about a minute to put on/take off the battery pack and drive unit from my chair and I could stow both in front of the passenger seat of my Honda Accord (and I put my frame on top of the seat).

              It isn't perfect, but it provides enough power to get to the next highest level of the average parking garage using the ramp without a single push stroke.

              I would say some finger function is needed to plug in the battery pack into the drive unit, and not everyone will be able to install/remove it from the camber tube mount while they are sitting in the chair as shown in the video. Similarly, not everyone can remove/store their FreeWheel on their backrest rigidizer bar while they are sitting in the chair. Now that I think about it, it is about the same level of difficulty to install/remove from the chair as a FreeWheel.

                Good deal! Would still like to see someone put it together from a car in a youtube video.

                  russell puts it together from his in the video, wtf.........would be great for like outings i would think, at the zoo, theme parks, probably not something one would use for hunting, camping and such, stick to the concrete world.....gonna try to get me one at the end of the month, go do my annual next month......the guy with the freewheel won't even summit his to the memphis va, they said they'd approve it in a minute and he'd probably sell a 1000 a year through them and he won't even acknowledge them......blows my mind.....

                    I could not see from either of the video's where the power button is located to accelerate without a push. Anyone know where it is?

On MaxMobility's YouTube video and web site, they don't mention it has a mode where you simply hold in the power button and it accelerates up to speed without the need for a push stroke. It is kind of like the Zinger, except it is lighter, more portable, and is actually being produced.

                    More after I test its outdoor capabilities.

                      This is a great design, love it so much. But the wheel design, no tire, no track, and I suppose the rubber(if I am not mistaken) will wear out very fast.

                        The 3rd pic in post #33 shows what looks to be the power button, it would be located at the front, in between your legs when in the chair. I would assume that you would tap the button to turn on/off, and maybe hold it in to accelerate, but I'm only guessing here.

                          You would be correct McDuff.

                          To address sowseng's comment about it having no tire or track. The weight of the unit itself is only 11 lbs. so there is relatively little weight on the drive wheel itself. How the unit is being used will determine how quickly the rubber wears out.

                          When using push stroke activation, the energy needed to accelerate to a given speed is provided by the push stroke of the user. During this time, the SmartDrive is essentially being pulled along and the user is providing the energy needed to overcome rolling resistance. Once the desired speed is attained, the SmartDrive simply kicks in to provide whatever force is necessary to maintain that speed.

                          When using push button activation the energy required to overcome rolling resistance and accelerate up to speed is provided by the SmartDrive itself. Instead of being pulled along, the unit is actually pushing the user/wheelchair until the desired speed is obtained. It is logical that there will be more wear on the rubber if it is being used in push button activation mode.

                          As for sowseng's concern about the lack of tire and track, the drivewheel was designed so that the rollers on the left and right half are offset--giving it sufficient traction for its intended use. The rubber rollers are also designed to be replaced when they wear out.The rubber segments themselves also rotate freely. This is a pretty clever aspect of the design because it allows the user to easily turn their chair in a tight radius with minimal friction between the drive wheel and the ground.

                          Actually, when the power is off, I notice its presence the most when I am pushing forward. I feel the "bump-bump-bump" of the individual rollers. I would probably keep a small bungee cord to suspend the drive wheel off the ground using my rigidizer bar if I were going someplace where I didn't need to use it, but didn't want to take it completely off. For example rolling a couple of blocks from my house to the bookstore.

                            Actually that's the never to be released new box frame from Top End. They abandoned it. Too bad, it looked like a winner.

                              Yeah, I was definitely interested. Last I heard from a TE employee, the one managing the process, it was all done except the final paper work with the gub'ment. It's a shame they went another direction, IMO. There seems to be a bit of a box frame renaissance, of sorts. I think they would have sold.
