Only a few months ago i reviewed the ADO A20 and they are back with this new release here
which is called the A20f the f of course stands for fat wheels so this model has 20
inch rims and 4 inch wide wheels which i happen to like they do add to the comfort being just nice
and big and cushy this particular bike like the A20 is foldable so the handlebars come down this
folds in half right here and it is powered by watt motor the battery capacity which is also removable
is 10.4 amp hours or 374 watt hours so in this in-depth review i'll go over the build the design
the components they have used in it what the ride quality is like and my experiences with this
breaking performance climbs over rough terrain and most importantly what kind of range can you expect
out of an e-bike like this so the box it came in was a little bit beat up and they could have
honestly put a little bit more padding around the sides i felt however it did come out of the box
undamaged all you need to do is just install the handlebars it does have a charger in the box which
is 84 watts and it will take around six to seven hours to fully charge the battery in this one
so let's go over the build and the design now of the A20f of course the f is mentioned stands for
the fat wheels and it is a different model quite a bit different to the a20 mostly the tires but
a larger frame on it too and that means it is heavier so this one's about 26 and a half kilos
and to accommodate that additional width of the tires being four inches there are some changes
with the frame versus the a20 so this bar here is a lot wider and i actually like the styling look
of this bike versus the a20 with the fatter wheels of course the four inches 20 inch rims we've got
160 millimeter disc brakes mechanical ones so they're not hydraulic i really wish they were
a very sturdy kickstand right here and the welds are very good and the frame here where it does
have the hinge very strong i like the way it mates up meets up together nice and flush and
when you're riding it it does not feel like a foldable bike a very rigid strong frame too it's
probably why it's so heavy got a handle right here adjustable seat post so it can go right up and
right down to a very low position so it basically caters for all riders the handlebars fold down and
they are adjustable too and i'll show you that shortly so this is our charging port right here
just like the a20 it does not have a dust cover over it for some reason whether it
came off in transit i don't know but it probably should have one just to stop any water getting
in there with the removable battery is housed within here so you can see a little bit of cable
cables along here cable management seems to be okay it's external of course because we need
the battery to be inside here and then we have a key so you get two there's a spare one and that
battery is lockable with inside and that's how you turn it on and off and you can remove it and
charge it indoors front wheel the same so we've got the 160 millimeter mechanical disc brakes here
and a front shock here this is a no name brand one now it looks like we might have about four to five
inches of travel or about four inches there but really the travel is only up to about here about
two and a half inches but it is a better shock than what we had with the a20 this one does not
bottom out on the a20 i would find that the front tire would actually strike the mudguard
and it doesn't happen here and of course we don't have mud guards and the same front headlight
as the a20 what i've seen on some other e-bike brands as well from china is this powerful four
led headlight on the front now i do like this one it is bright and you can't even see it in daylight
and like basically all of these cheaper brands of e-bikes they are using shimano so we have the
seven speed right here shimano derailleur and it is aligned perfectly from the factory i don't have
any issues going through the seven gears and it's better than having just a single gear which some
e-bikes i've reviewed in the channel do have i prefer putting it into a lower gear to help me
up the hills when i'm pedaling myself and then our crank here at the front does have a plastic
guard around the outside of it the chain brand is from kmc so it is good to see for the drivetrain
they are using at least brand components here and as well we have a minor change here so with this
latch here they used to have a security that would slot down into it it's now incorporated
into it we will fold the bike and you simply need to with this open here and you pull that
up and it releases it does rattle a tiny little bit and i sometimes hear it when going over bumps
and the way to open it up is that you push that and then you need to pull this lever out of course
and then it unlatches and you can see this is where the battery actually locks in place so if
i move that key there you see that will go in and the design of this and the build here very strong
and again i do like the welds and the finish off this frame is better than the a20 that i reviewed
so a standard size seat here there are no springs in it there is no shock in the seat post either
and as i mentioned before it's adjustable so it can go right down really low we do have a
reflector at the rear and i've just added my own led rear tail light here so that is what it is
missing i really wish they would incorporate a tail light into these e-bikes which most brands
don't actually and then in the rear hub right here you'll find our motor so this one
350 watts 36 volts and it's powered by that 10.4 amp hour battery and this is what it looks like in
its folded form so this makes it a lot easier to place this in the boot of a car or the trunk and
transport around or store it under some stairs for example and our handlebars right here so we've got
a usb port here that's powered so you could charge your phone if you decide to use the phone holder
that they do include in the box now it's quite cheap and tacky and i didn't really like it so i
didn't end up mounting it in the end our shimano 7-speed gas selector here so this is going down
the gears pressing this is to go up now they don't have lock grips on this we do have right here
an accelerator which is used in the assist mode two and three and this is our computer right here
so i will power that on for you but just as i do that just to show you that we've got your typical
lights on and off so that switches in and stays on in the on position i leave
it and right here we do have a buzzer which is very loud i'll give you a sample of that now
so here with the computer it is the s 866 i've seen this on various other different e-bikes out
of china so assist mode one when you pedal the sensor there will give you a bit of a boost it
detects that but on level two and three you must use then the accelerator to get the pedal assist
so tapping right here we can go through and see our voltage time the odometer
and trip meter let you know the mileage i can get out of this towards the end of the review of
course after i've tested this for a few days this is just my first day with it as i'm recording this
so this is backlit too as well so you can make it out at night and you can also read and make this
out in direct sunlight which is great that's for our brake levers here pretty standard okay quality
there's no sharp edges on this at all and they do need a bit of an adjustment as you get it out of
the box which is typical and standard so what i do is just tighten this up and to make sure it could
pull through the cable on the end just a little more to make sure they give you just the kind
of feedback you want from your brakes but i'll be doing a braking test later on in this review and
i'll let you know about their performance okay so what's it like to ride so pedal assist mode
number one will automatically give me a little bit of power to the motor to help me up the claims
and it detects your pedaling straight away and it does that now you must be on two or three pedal
assist modes and then use the accelerator to get up for example little climbs like this one here
which is not a problem at all for this bike but i'll be testing out a larger climb soon here
now the geometry of the frame here it's comfortable plenty room
like my knees they're not even near the handlebars like i've got more than
about two hand widths away from the bars there my knees so very comfortable plenty of room
and for my climbing brake test so this is a steep climb up ahead it's about 25 degrees the
gradient on this one 25 30. let's see how the a20f handles this so this climb on level two
very easy actually i'm in a lower gear or in fact the lowest gear having to work a little
bit so it's just level three slightly easier i could even in fact go up a few gears here
and now it's starting to get up this hill so much easier but you still have to work a bit
on these steeper hills these climbs you're going to have to pedal
so one thing i like about these tyres is the noise of them they're very loud
braking test here now so up to 37 full on the brakes
and not too bad that could definitely be a lot better i feel it really does need hydraulics
these bikes especially with the speed of them and the weight of them really do need hydraulic brakes
now riding along some very rough cobbles here it's up and down and all over the place now because
these are fat tyres they're helping soak up a lot of the bumps here so it is more comfortable
than that of the a20 model with its standard size tires the front shock is basically not
really doing anything and i can hear some rattling coming from the battery that is within the frame
now maximum speed 25 kilometers per hour i can get a little over that but it is limited
and i have not unlocked it so arriving now to the end of las rotas the
typical route that i do with these e-bikes and e-scooters little overcast today and
busy with a lot of traffic and people getting in the way opening doors
there we go i've made it to the end
now let's talk a little bit about the range you can get out of this so i currently have done 35
kilometers on this and two bars are showing when i'm not using it but once i start to use the motor
it will drop down to one bar so really i think i can get another possible 5 10 kilometers more
so that brings the range for my weight of 80 kilos around 40 45 kilometers which is very
average there so make sure you factor that in if you're going to be buying one of these and you
expect to be able to do say 60 kilometers that's not going to be possible at least not at my weight
and i did do quite a few climbs so i went at least up three big climbs and that has a huge impact on
the battery life it really does burn through it most of the time i was on the accelerator
and on level three so the pedal assist on this one like the a20 is not one of the favorite things i
think the pedal assist on this is not a good system because they use just level one to give
you the pedal assist when you're pedaling it detects it the crank sensor right here
and then it will give you some assistance but if you want to use the accelerator grip
right here you need to use then level two and three now i have seen on their website
that this model when it's going to be sold on indiegogo they have changed the controller in
it so it won't be like my one here it's going to have what i would call like a normal pedal
assist levels to it so level one will be like 25 percent level two 50 i believe and level three
i believe there will be about 75 assistance and then you can use the accelerator trigger
on the grip here sorry to be able to get 100 power then and up to 35 kilometers per hour
if you unlock it now the build quality of this one the frame is certainly better than the a20
the finish of the paint job the welds and where it meets up and then the latch mechanism i like
it feels a lot more secure i like the way that they've incorporated that latch with an all-in-one
safety lock to it and then the handlebars is about the same now just putting on both of those brakes
it really doesn't move around there's not a lot of play in the frame and i like how large this
frame is so the seat can go up quite high you can drop it down very low as well and the handlebars
are relatively high and they can go even higher which i don't believe a lot of people would be
messing about with that really so it can cater for all riders the size of it now braking performance
i would not rate as wonderful these are mechanical disc brakes they're no name brand brakes
and the braking performance after 20 kilometers did improve once i started to really bed in those
brake pads which is good now the shock here on the front much better than what we had with the
a20 my a20 shock would bottom out hit the mudguard strike it and i was really not happy with that but
this one here you can see apply a bit of pressure that there is about maybe two inches of travel
maybe a little more as a little stiff but it's a much better shock but then again it is just
a no-name brand shock but we do have a kmc chain we've got the shimano gears changing changes with
the gears have been perfectly fine for me so i've had no problems having been grating gears
and i haven't had the chain come off or anything like that no issues the changes a typical shimano
they've been smooth crisp and accurate and no problems there the power from the motor so 350. i
know there's other models out there with 500 so if 350 is not enough for you then of course you need
to look somewhere else but i think for the price that it's going to be selling for which is under
i believe 800 euros on indiegogo i think that's okay and i would definitely get this model over
the original a20 if you have rough roads the big one for me is the chunkier frame but these tires i
actually really do like these flat tires so four inches wide they really help soak up a lot of
bumps if you run a lower psi right now i'm running 20 psi but if you run even less than that which
these tyres can actually do they soak up then a lot of the rough terrain and help out just give it
a smoother ride give it a little bit more traction and even for off-roading a little bit will be okay
but this is not a downhill bike this is not for trails definitely not with this suspension
set up this is still more really full road to bike like this so thank you so much for watching
my review here of the ado a 20 f i hope to see you in the next upcoming e-bike review bye for now
