hi chris here and my assistant in the corner vera with the hemo zb20 so this particular foldable
e-bike it's heavy it weighs 28 kilos it has a front shock and those iconic fat
four inch wide wheels 20 inches is a pretty standard size now for the foldable bikes
but with these wheels on it it does have a more sturdy wider frame and because it is a foldable
there's a little bit more weight to it due to that now the battery located in the frame right here is
10 amp hours i'll let you know what i can get out of it range-wise the handlebar will fold down as
well too and i'll seat it's large it's comfortable it has a built-in pump with it we have six gears
there's shimano gears and a 250 watt motor here powering us along with the zb20 max the frame
quality does seem very good with solid looking welds and it's not going to break in half like
the feeder x not this particular bike so there is a little clip we need to push forward first and
then you need to just pull on that and that undoes it and you can then fold the bike in half and
gain access to the battery this is what it looks like then and it's folded state so it's in half
handlebars are down seat post is also down you can now fit it for example under a stairwell or in the
back of a large car that is you don't want to be lifting this up any stairs because it does weigh
that 28 kilos it is heavy and even though it's folded up now it's still relatively large compared
to other foldables with it unfolded you can then insert the key and slot out the battery like so
the pedals on this e-bike they're made out of a hard plastic and they are foldable pedals we
have a plastic chain guard here and the chain brand is a best chain brand never heard of them
before the shock here is generic it's not a brand shock so it's not a rock shock or a fox no now it
is lockable there is approximately two inches of travel which is not bad i've got a reflector
here and a bright led headlight sadly our front hub here does not have a quick release so you're
going to have to carry around tools if you're going to do a repair on the spot but hopefully
you won't have that issue i do recommend using in these large tires some anti-puncture solution just
in case the four inch wide fat tires that they went with are cst bft and i do see a lot of cst
brand tyres on these chinese e-bikes the bike does come with a sturdy kickstand it does not rattle
the battery which of course is right in here and it seems to rattle around which you'll hear later
on with my road tests so the charging port is right here you can charge it either in the bike
out of the bike and you're looking around four to five hours to charge the 10 amp hour battery the
seat very comfortable plenty of sponge in it zero complaints from me so the height does have a quick
release on it the seat post at least so it's height adjustable and if you pull it right out
and then check the end of it unscrew it right here you'll find that there is a built-in pump which is
quite ingenious of them to have this so you can use that pump to top up those tyres if you need to
coated with the bike is this rare tail light so it has a reflector and then these leds at the top it
is nice and bright and it's great for safety and there are reflectors in the spokes of each wheel
the bike does have lock grips and they are not going anywhere so here is the controller the same
as the hemo controller and the z20 that i reviewed we've got a trip meter odometer and then you've
got your pedal assist levels so eco mid and then high most of the time i'm using high and sometimes
medical ecos if you want to get the maximum range out of it so down here there are two buttons to
power it on and there's the mode button now if you keep holding the up the plus button here
that turns on the front headlight but not the rear one because that operates on batteries i do have
a complaint with this controller and i've screwed it up to the maximum tightness here but it's still
loose so it's actually just a little too big for the diameter of the handlebar and that's a slight
annoyance then we have our shimano gear selector right here so up the gears down the gears here
a little bell better than nothing our handlebar this can fold down as well so it just collapses
to one side of the bike like so and the latch on this is very strong and it clips in securely
there it's not going anywhere now the height of the handlebar is not adjustable unfortunately
now what's i like to ride this beast of an e-bike so the crank here uses a speed sensor and it's not
a torque sensor the torque sensors are the best but normally around this price category and group
of bikes they don't use the torque sensors some of them do and i really wish him i would have
so i've got it in the high mode and there is no accelerator with this it's not actually legal here
in europe so it's kind of good that it doesn't have it so when i start the pedal there we go it's
detected that i'm pedaling and it gives me that boost and you notice it straight away on the high
gives you quite a bit of power there and then the mid not as much and eco it's just a little bit but
eco is not too bad for especially cruising around on the flat here is quite good and comfortable so
why am i pointing at my legs here well i'm just trying to show you that the handlebars there's a
bit of room here and i'm in quite an upright position so it is comfortable and the seat
caters to pretty much all rider heights which is good now i have a tiny little climb up here
and you can hear that why i went over that and why i'm recording this clip is just to point out
that there is a rattle now it's i believe it is the battery rattling around inside the frame here
that's what's making that noise it is irritating i could probably fix it with a couple of little
rubber shims or something on the battery when i slide it in so it doesn't feel loose in there
and rattle but really i shouldn't have to do that hemo i hope they fix it steady climbs like this
one right now which is not that steep at all it's nice and easy it's doing without really me having
to work up any sweat barely any effort this is in the high mode now if i put it into the mid mode
straight away it's almost like i noticed i drag on the motor and everything but it's still easy
enough now in eco i have to put a bit of work into it now and i'm feeling that but let's move over
now to where my steep climb test is so here it is my climb point so this is about 25 30 degrees
and i am in the sixth gear so i'm going to lower down the gears a couple
this can kill some e-bikes and some of the e-scooters i review but look at this not a problem
plenty of climbing power and i'm in the fourth gear if i give it a little more
it's helping the motor and that's in the high setting so if i put it on to the mid
mid still seems to be okay and eco really not that too not that different actually so
it climbs really well i could probably even go up a few gears here with it
or drop them down if it's a super steep climb it's a great climbing performance with the zb20
now for my braking test so we've got mechanical disc brakes 160 millimeter so about 30 kilometers
not too bad that braking performance now for the price of this bike they should have gone with
hydraulic i think if anything's over a thousand euros a thousand us dollars put hydraulics on
them now the discs themselves the pads on these brakes they do bite into the discs quite well
a lot better than some other brands i've recently reviewed so these overall aren't bad brakes that
come with the zb20 but if i was going to upgrade anything it would be those brakes another thing to
point out as i cruise along here is that sometimes my feet my shoes hit the frame and that's because
the frame is extra wide to cater for those four inch wide tires didn't have this problem on the
z20 from hemo because that's only got the two inch wide tyres but this one it occasionally happens
so you need to adapt your riding style so you don't end up striking your feet against the frame
now if you watch my other e-bike reviews you'll recognize the coast here this is the
end of what is called las rodis mediterranean coast of spain
and the ride so far with this bike is good excellent climbing performance good top
speed i can easily ride over 30 kilometers per hour unlike some of the other 20 inch bikes and
i love the noise that these big fat whales make lots of road noise i actually like it
so how does the zv20 handle really rough roads like right now it's very bumpy it's doing fine
because of the fat wheels and the front shock is helping out soaking up some of these bumps
but listen to that battery it is rattling away it's super annoying now you have to do something
about that battery can't put up with that all the time rattling away now our range hemo states that
you should be able to get around 80 kilometers out of this but of course that's ideal conditions
no headwind using one of the eco settings there of course now i was riding around mostly on the
mid or the high setting and i'm losing around 11 kilometers per battery bar there on the gauge so
i'm looking at about 50 kilometers range with my 81 kilos and some small climbs i do often
ride over 25 kilometers per hour though so on the street when i was riding then i managed to get up
to about 28 29 sometimes 30 kilometers per hour top speeds there where it's not even using the
motor so the mileage is going to vary but worst case scenario i do think you are looking around
about that 40 kilometers and then best case maybe 60 but certainly not the 80 that they
claim you can get out of it no so what is the good about this bike well it's ce certified
the quality of it is very good so it's better than 80o bikes that i've reviewed fee do and a
few of those other brands uh angry is another one it's better than those definitely it has the nice
fat four inch wide tires on it the paint job this khaki color looks great it's a very good finish
it folds in half and that is very good it's got a powerful motor so good for climbs and the brakes
are actually good even though they're mechanical disc brakes and they bite in though those pads
meaning that the performance is fine i can't really complain about it the front shock can
be locked out now onto the cons they're minor little things here and that is that there's a
noise a rattle okay that was a chain slapping then but i sometimes hear the battery inside
here or either the front shock can sometimes make that rattling noise you probably heard it
with my footage with it with the gopro the other is the pedal gets quite close to the frame here
and i sometimes find myself hitting with my feet the frame because the frame's a lot wider because
it needs to cater for those wider tires which means you need to adapt your riding style to move
sometimes your feet a little i find that a little bit annoying the other is very minor too the
display moves about i've tightened it up as best as i could but there's a bit of movement in there
and then finally what about our pricing so get ready ready for it 1600 euros is what it costs
so it is an expensive bike better quality than the other models i have reviewed but
it is a bit pricey i think for what it is so hopefully they can work on that price hemo and
bring it down a little bit i know it is se certified by sgs they would have cost them
a bit of money to do that and it does have a very good build quality the seat is also good
it's just a bit pricey there so thank you so much for watching my review here of the hemo zb 20 max
