EVEN ALLOWING for the fact that it uses more efficient brushless motors (which helps it go further on its small batteries) it still doesn't quite seem possible.  Good standard powerchair motors are 70 to 85 percent efficient complete with gearbox already.  Brushless motors are still not 100 percent efficient.

Usually brushless motors are around 88% to 94% efficient. An approximate gain of say 10 to 15 percent in efficiency. But with just 44Ah rather than the usual 75Ah to play with... According to my maths keeping the same range isn't possible. 

Since a 6mph powerchair NEEDS 70 to 75Ah batteries for true all day capability with a heavy adult,  then I would expect that this chair needs AT LEAST 55/60ah batteries to keep the same range/performance level with its more efficient motors. 

But they are smaller. Much smaller!  It only has 2x 24v 22ah batteries.  Total 44Ah. And yet they claim 45km range!  It all sounds very unlikely to happen judging by my own experiences with powerchairs/batteries and motor systems.

Expect both range and battery replacement issues (in my opinion) with this chair if you use it heavily as I do. I wonder why they offer just 6 months warranty on batteries?

Especially if you are heavy or live where there are lots of hills or ramps, intend to use it on grass or loose surfaces. Particularly worrying if you drive off road, which it claims to be good at...

Effectively its "fuel tank" is just over half the size of any normal "full sized" hi end powerchair.  So be wary. Not everybody needs the kind of performance or range I expect from my powerchairs though.

 

GROUND CLEARANCE IS GOOD AT 17cm

Because obviously they have no space problem because of the small batteries!  I also design power wheelchairs. My latest one has FOUR or FIVE TIMES the amount of stored energy at the high discharge rate in its high tech lithium batteries.

Because it needs that power to be useful off road! BM3 here

Programming on all Powerchairs is dismal at very best and although I didn't drive this one the guy who owns it said it was as "soggy" much as I expected. 

All "bought" powerchairs are like this. It makes real accurate control impossible unless you slow right down.  The only way to fix this with ANY powerchair is to take charge and reprogram it to suit you, at a lower level than a typical end user / dealer programmer will allow. 

This needs an OEM level programmer normally. Which causes all kinds of problems as they are all but impossible to get hold of for most people. So you will likely be stuck with the OEM level programming it comes with.

The dealer will not be able to use anything but an end user/dealer programmer which may help a little but will not fix the problems.

See programming but I don't know how easy it will be to get hold of a programmer that can fix this chair! Its electronics look bespoke rather than one of the big three or four control system manufacturers such as Dynamic or Penny & Giles that the other powerchair manufacturers usually fit.  (Even if "rebranded")

I WOULD NOT BUY ANY POWERCHAIR WHERE A LOW LEVEL OEM/ENGINEERING PROGRAMMER WAS NOT EASILY AVAILABLE (not a useless "end user" version) to allow me to properly configure the powerchair to correctly suit me.  Although most people don't seem to care if only because they do not understand the difference!

The anti tip wheels and bars are too long (so they will hit everything around me indoors) and will prevent your head being the first thing to touch a wall when you reverse. So making the chair longer than it needed to be.  And is an issue when trying to drove off a curb too. Too low leaving you hung with no drive wheel in contact with the ground. See forum....

It has a good central space saving footplate (no corners!) rather than the awful swing away ones fitted to most powerchairs that hit every doorframe...

Normal rehab seating cushions can be used. It can drive short distances at lower speeds with just one battery pack fitted. Although I wouldn't recommend this unless you like buying new batteries.

And the rear wheels are too far back compared to the seat giving a nose heavy "long" configuration which saps power, hinders manoeuvrability etc. And makes it feel like a truck indoors. But all modern rear drive powerchairs have this C of G issue because the manufacturers are afraid of the chairs tipping back on slopes and ramps.  Never bothers sports manual wheelchair suppliers though? Or me. I modified my own chair to be as tippy as a sports manual wheelchair.  This way it feels lively, wheelies at will, and steers better and saves much battery power.

And its very wide for no obvious reason. Its a full 26.5 inches wide! That's over a full inch wider than my own chair (with 12 inches of fat rubber tyres included!). EVERY INCH COUNTS when indoors. So you will need lots of indoor space. 25 inches is a good target for any powerchair intended for indoor use.

That's why I use tubeless ones on my own powerchairs along with some off road "gunk" that stops deflation before you know it should have deflated! So check the sizes (and prices) and make sure there are alternative tyres available and that you are not relying on the powerchair manufacturer for replacement rubber!  Because I see none anywhere. They are again bespoke solutions I think at high cost rather than standard tyre sizes.

As usual powerchair manufacturers are still giving us tubes tyres! Tubes pop or burst like a balloon. Not good if you cant walk. And /or solid or foam filled tyres are horrible, hard, heavy and eat batteries etc.

Battery charger is both automatic charger and maintainer (includes a float charge after charging for long term connection and storage of batteries.) Much like most modern multi stage logic controlled powerchair chargers. (Although some don't "maintain" or float long term after charging). A fast charger should be included as well but like all over the counter powerchairs its not included.

Range 45 km / 30 miles A very, very dubious claim with its 2 tiny 24v 22Ah batteries!  I would put a weeks wages on it having much less range than my own "normal" brushed motor powerchair has.)  They do three versions 4, 6 and 7.5mph. The 7.5 (8) mph one will be the worst one here by a large margin no matter what their claims. 

The slowest 4mph one MAY have enough range to be usable all day. But speed is very expensive in terms of power. It takes MUCH MORE power (or battery energy) to double the speed. So the fastest version at 7.5 mph cant possibly have the same range as the 4mph one!  I wouldn't buy a fast one if you weigh more than a 12 year old girl...  Because its torque level and ramp climbing ability and range will be dismal 

Length - 111 cm that's much longer than my own powerchair which is not good indoors or trying to manoeuvre in toilets or pubs etc. Or for getting in or out of my van.

Width - 68 cm that's wider my own powerchair. And a problem. Much like the comments above. How can they manage to make it bigger in every direction than my own powerchair whilst only fitting batteries just over half of the size?  And my chair has a full FOOT of tyre rubber width too...  I don't think PowerChair manufacturers are trying very hard.

So it is a little wider and longer than it really needed to be. That is its Longer and Wider than my own powerchairs which is crazy since they also have those huge fat easy riding comfortable (outdoors) tyres with some off road beach/sand capability too. And 70Ah batteries (almost 2x bigger!)   It should / could be much narrower!  And shorter. Every inch or part of an inch matters indoors and in confined spaces like vans / loos restaurants, public transport etc.

Tyres (Tires) These are great sizes for indoors as well as reasonably good outdoors on a rear drive powerchair on smooth or reasonable surfaces.  These work great indoors and out on smooth pavements and carpets alike but unfortunately much of the world isn't smooth and this can be a problem with almost every modern powerchair.
