Back to this specific chair, I have not been able to get one of these to try personally (yet). But have seen one in person close up in my house and it uses the exact same electronics packages and options as the R-4000 powerchair does so much of the comments on that chairs motors/controllers hold true here as well. The only real difference between these two is where the drive wheels are situated and the casters. These two chairs are basically brother and sister. 

So please read that review to gain an idea of its power and motor capabilities as well! Much of that review also applies to both this 6 wheel Q6000 and Q6000Z as well as to the R4000 and R4400. They all use the same motive power components / controllers etc. So its important to read that R-4000 page if you are considering buying one of these Q6000 powerchairs.

A quick controller/speed package summary follows anyway!

Avoid the 8mph "Hammer" motor option, unless you are light/skinny and don't go very far each day. It will have less range and shorter battery service life and does definitely have less torque (power) than the 6mph version does. (And that's important for control. We all want "faster" but its not always a good idea.)

And that 6mph R4000 chair didn't have very much torque to start with! And definitely opt for the 100 amp control system option rather than the 70 Amp one!  Again this is important even on the 6mph version, especially if you are heavy! At least it is if you intend to go up ramps, thresholds etc with any kind of control capability or real "torque" for control in difficult situations. Again this also depends on programming too.  The Pride Q-Logic control is really a just a rebranded Curtis Mc-2 100 amp system. At least as far as we can tell. It may have pride specific firmware though.

Stephen in his Q6000 in my kitchen today... Note one of my own home built / seriously modified powerchairs  on the left!  He had come to see me as he is actually building one of these too. A clone. To replace his indoor chair (the Q6000) and his Frontier X5 outdoor chair since mine does both jobs better in one single powerchair.  No need to keep swapping or driving around with two chairs...

The difference between the Q6000 Q6000Z is basically just the size of the casters. On both of these Powerchairs the casters are tiny anyway and very solid!  I think only Q6000 is available in the UK and 6mph. But in any case the Q6000z is only a minor improvement outdoors. Its just not cut out for the outside world!  Just 5 inch diameter front casters on the Q6000 and just 6 inch on the Q6000Z.   So you may as well forget the Q6000 for outside... (The Q6400 just has the 8mph package as stock.) On the others its an option that is a bad choice anyway at least for most "grown" adults if you expect any real range and torque. There's little enough of that as it is.

There are minor detail differences in the caster arm lengths for e.g. too but caster size is the real difference that's important to us here.

On these sorts of surfaces, and indoors its at natural home. Although I prefer not to have casters sticking out behind me when moving about in a busy place! They hurt your toes apparently according to all the people around you... 

One thing that really bothers me about these chairs is the sheer number of brackets and parts that appear to be randomly bolted together. Not exactly clean elegant simple well thought out design, more designed by committee of hundreds but it works... On the flat. And indoors. Stephen suffers from pressure sore issues, as I do, and wants a MUCH smother ride than this chair can offer with its small hard drive wheels and casters. And no suspension on the drive wheels that you are sat on.  He needed bigger fatter softer wheels and tyres. Hence he bought a Frontier X5. Which is too big and long and high indoors and wont fit his van... Actually he lowered the seat but its too wide to drive from as it cannot sit centrally in line with the steering wheel.

The idea being that smaller casters (Q-6000) are better indoors since they hit less of your surroundings when manoeuvring but are really completely useless outdoors other than in shopping centres etc. And because there are 6 wheels and a caster sticking out in each corner on mid drive chairs like this one that's pretty important.  And the one inch "bigger" (but still tiny ones) on the Q-6000Z version work better outdoors. Which is true to a VERY small degree.  Its still bone shaking...

The "bigger" 6 inch ones on the Z version are still just 6 inches!!!  That's still tiny.  There are pot holes where I live bigger than that!  The ones on my own chairs are 10 inches diameter and pneumatic so absorb shocks and roll over uneven ground massively better and are just about bearable outdoors in the real world where even the smoothest pavements are to but it mildly very rough!

Well I can assure you that with the BIGGER but still tiny 6 inch casters, the real world is still a step too far for this powerchair!  I watched a guy trying to drive his Q6000 over the same car park and building entrance area that my own chair just glides over smoothly. He was rattled about horribly and looked very uncomfortable.

Remember that even a very small 3 inch curb or pot hole, or threshold is the centre axle height of the wheel!  At axle height it will hit what appears to be a solid wall as far as that tiny wheel is concerned. And with solid tiny tyres they "see" (and you will feel), every tiny crack and bump along the way. And quite noisily...

I have seen them in action and had many emails from readers asking about how to improve the ride on supposed "smooth" pavements. This is a chair that WILL go outside and on dry grass etc and even up small curbs. But you will not want to do it very often! 

I have at least 4 emails recently from people complaining that its the only chair they have used that gets them literally "stuck" crossing gravel or uneven broken surfaces as the 4 caster wheels leave the drive wheels spinning uselessly in mid air.

Not exactly elegant from the rear either is it? I have never seen so many tiny parts, bolts, springs, unpainted plastic parts, cables and wires hanging seemingly at random in my life!  Sort of an explosion in a powerchair factory and it all stuck. And they left it looking like that! 

If I had built that I would consider it a prototype and would come back and build a FINISHED version that looked tidy and still worked the same... It honestly looks dangerous. Anyone could yank out a cable either on purpose or by accident and you are screwed...  And these are the offending casters sticking out at the rear. They hit furniture, as you manoeuvre. Worse they run over peoples feet when in a busy pub for e.g. and try to turn or move about. What a great idea!  Its why 6 wheeled powerchairs are a bad idea. An engineers worst nightmare and always a compromise.  Still it clears a gap around you. Note all the scratch marks on the side shields, And note that they are small, and solid. Like an office chair. Try your office chair in the street!

It uses solid (foam filled) drive wheel tyres as well which already give a VERY "firm" ride on all powerchairs with small hard sidewalls compared to my own powerchair and its tiny solid casters that hit every bump and crack in the pavement certainly wont help the ride comfort!.

This chair is better definitely better suited to indoors. In which case you may as well find a smaller width powerchair to make life easier in the first place. Maybe a narrower Pride powerchair like the 600?
