Alber Adventure Powerchair - (Frank Mobility)  

The Alber Adventure is a Rear Drive Powerchair that is designed in "modular" form so that it can be disassembled for transport should you wish. Although I have not actually tested how difficult this is.

Various site visitors tell me its pretty difficult to do quickly and heavy though. So I suspect its something you would only do if you really have no choice!  A more sensible vehicle is always a better full time solution and a Powerchair that doesn't have to break apart for transport.

And the "arms" on the one I was looking at were very weak and "loose" (rattle) too.

They definitely wouldn't be able to stand up to the rigours of a heavy adult like myself using them to "pressure lift" every few hours or lean on heavily while transferring! 

This is a fault with many powerchairs, scooters etc though. The manufacturers don't seem to get that we often have no choice here!

One other concern is that while it claims to be both "fast" (8 mph possible) and have all day range it uses pretty small batteries. That just does not add up.

Even allowing for the fact that it uses efficient brushless motors (which helps it go further on smaller batteries) it still doesn't quite add up.  Good standard powerchair motors are 70 to 85 percent efficient complete with gearbox already and brushless motors are still not 100 percent efficient. Usually they are around 88% to 94% efficient. Sp an approx gain of say 10 to15 percent in efficiency. But with just 44ah rather than 75ah to play with... 

Since a 6mph powerchair NEEDS 70 / 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 they claim 45km range!!!  It all sounds very "unlikely" to happen...

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.

Or 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" powerchair.  So be wary. Not everybody needs the kind of performance or range I expect though.

Ground clearance is good!  17cm. Because obviously they have no space problem because of the small batteries...

Programming on all Powerchairs is usually 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.  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 programmer will allow.  Which causes all kinds of problems as they are all but impossible to get hold of for most people.

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 other manufacturers usually fit.  (Even if "rebranded"...)

I would never buy any powerchair who's manufacturer will not sell me a "real" low level programming tool (not a useless "end user" version) to allow me to properly configure the powerchair to correctly suit me.

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.

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!) So you will need lots of indoor space. 25 inches is a good target for any powerchair intended for indoor use.

As with all powerchairs avoid Recaro or automotive style seating unless you are extraordinarily small and light as it moves the chairs C of G higher and further forwards making handling and steering worse.

Its bespoke tyres are rapidly getting a reputation as fragile and puncture prone... Which doesn't surprise me since 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 alternatives!

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 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.

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 4x the power (or 4x the 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 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. 

Max loading 140kg,  Total weight 96.7kg

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.

The front casters are sensible diameter which means they are quite big so they are reasonably capable outdoors compared to other chairs with smaller casters.  See tyres and Solid or Pneumatic? to know what you really need!

Although 10 inch casters are better outdoors though (3.00 x 4 tyres) and the extra width is better on uneven surfaces or sand/snow.

In a rear drive powerchair like this Alber Adventure, these 2 larger caster front wheels seldom cause any problem indoors compared to a 6 wheeler or centre wheel drive chair as Its easy to predict or even see where they are or will swivel or move to as you manoeuvre in a tight spot.

Mid drive, front drive, 6 wheel platform powerchairs all need too many extra wheels sticking out in all the corners, and behind you.  So these types of chairs usually use much smaller caster wheels to try and keep them "small" enough indoors so that the casters don't go hitting everything all around you.  Leaving them at a disadvantage outdoors in the real world or in snow etc  (Powerchairs and Snow)

All powerchair suspension, is pretty useless. We don't travel fast enough for it to work. And it does not have enough movement. Run over a rock. You feel it right?  With or without this suspension. Well that's because the suspension cant work properly at such low speed. Compared to say a big soft fat balloon style tyre that deform around any rock / object, where you just don't feel it.  See  much of the world isn't smooth And why I chose to throw away the suspension on my powerchairs and fit these...

It uses brushless gearless motors inside the wheels for efficiency which can only be a good thing but the tiny batteries are just not up to the job of a "all day" powerchair as used by a typical Paraplegic / Quadriplegic user as I see it.  If the manufacturer disagrees then send me a chair to test for a few days and I will use it in my normal daily pattern and find out for sure. But the numbers don't really add up. So I doubt they will! The offer stands however and I will rewrite this evaluation and admit I was wrong!

As a "shopping" powerchair that you can take apart to fit in the car it makes some sense due to the small batteries being so much lighter. A better vehicle makes far more sense in the end though.  But don't expect to use it 16 hours a day, walk the dog in the woods, go shopping, and then go out to the pub in the evening on one charge. If you do, and you don't actually run out of power you will still get very short battery life due to the depth of the average discharge/recharge cycle.
