Finally i've gotten around to testing a 26 inch fat wheeled e-bike a lot of you been requesting
that normally i review just the 20-inch fat world e-bikes but this one is a complete different story
here it's an absolute monster it is the go-go best gf600 why is it such a monster well it's got a
thousand watt motor in the rear hub it rockets up climbs and thanks to these extra wide spongy tyres
it really does handle even rough terrain like this quite well climb up it really well in fact better
than my trek rail 5 which really surprised me and with this bike we've got seven shimano gears
160 millimeter mechanical disc brakes both front and rear from zoom the front shock gives us about
three inches of travel you can also lock it out we have a large display up to five different pedal
assist levels the maximum speed this can go up to is around about 40 41 kilometers per hour or if it
is limited then it's 25 kilometers per hour the battery bank here is external and the controller
so this battery is 13 amp hours and it should give us a range they claim of up to 110 kilometers
which i will be putting to the test i'll do my climb test braking test i'll let you know
exactly how it rides and why i'm so shocked about this bike's climbing performance now i just love
these huge tyres on it 26 inch rims but the tyres are four inches wide however around about three
and a half or so inches tall making the overall diameter very close to that of a 29 inch bike
now these tyres run a ridiculously low pressure in them only 20 psi is the maximum you can put
in them but i'm running 15 which is just fine and that allows these tyres to soak up any minor
little bumps it gives us more traction more grip makes a ride a little bit more softer
and they are meant to be quite puncture resistant to these tyres which is an added bonus our front
crank here this has 52 teeth the pedals are made out of metal and a very standard shimano tourney
here seven speed that's entry level gears that are on this bike the seat is quite a large one it's
wide it's got good padding but it does not have a reflector or a rear tail light so the front shock
here has a reasonable amount of travel as you can see up to about here which i've calculated to be
three inches maybe a little bit over of travel it is lockable so if you flick this you can
completely lock it out and we do have a powerful four led headlight with this so when you're riding
at night it's bright enough to light up the path ahead of you so you can ride safely the frame does
have your standard drink holder mounting point with it the controller of the bike is located in
this box right here so it's all external there is some internal cable routing which is good
and the battery located here there is a main on and off switch this battery is 13 amp hours
and we do have a little gauge built into it you press that and you can see the remaining level
which is handy if you're charging it if you've got one inside and you can remove it from the
frame so it comes with two keys and you just simply turn that and then you can pop that out
and remove the whole battery we do have some nice wide handlebars and on the left here you'll find
our controls so this is m2 power it on this is up and down the pedal assist level so zero two five
zero lets us use the accelerator and then the grips here these ones they're not lock grips but
they are not going anywhere which is good this is our twist accelerator so if you are in mode zero
and you twist this it will just take off so you do have to be careful with that
this is to go up the gears down the gears and our front brake lever the screen on this is an
s700 is very clear we've got our speed battery gauge right here the pedal assist levels odometer
time trip meter is there and the screen is backlit so that means you can make it out when riding at
night which is good so what is this bike like to ride well you can see i've got ample room for
my knees nice wide handlebar upright riding position it feels very similar the geometry
and the size of this frame to my trek rail 5 that i own as my main bike now that speed sensor it's
not a torque sensor it has but a speed sensor as soon as i start to pedal it kicks in really quick
not like some other e-bikes so there's quite a bit of delay no it doesn't happen with the
gf600 and it just rockets off there's so much power 1000 watts on tap now the other thing
to point out with these tyres because they are so large we've got almost a diameter of around
about i think it's about 28 inches or so so almost a 29er really the diameter of these
tyres and it's so great for getting a decent good top speed now if i pedal really hard i'm not even
in the highest gear here i can easily get over 32 30 40 up to 35 kilometers per hour so top speed
is excellent thanks to the gearing and mostly because of the large diameter wheels
now if you use pedal assist level zero and i'm writing here i've got no pedal assist
whatsoever but that does enable this right here which is the twist accelerator so i can
use that start to ride so if i'm feeling a bit tired i want a boost i can just accelerate with
that i'm getting that full 1 000 watt motor power 2 up to unlimited 41 kilometers per
hour and i'm here now at my climb point so this is approximately 25 30 degree climb it is steep and
that speed sensor really good on detecting when i'm pedaling if i stop you hear it cut out the
motor and as soon as i start to pedal a little it then detects that straight away and it's
giving me that power that i need so i'm in pedal assist level number two and i can comfortably go
up this because it's just got so much power so i can even go up gears i'm in the second
gear now by the way the shifts of the shimano that it's got at seven speed really good nice
and crisp smooth changes no grating of gears so it's pedal assist level two what about five
so five i can even give it a little bit more and start to climb up this effortlessly i'm not even
really working up a sweat now what would happen if i put it into the lowest gear now and completely
turn off that motor so zero oh oh can you feel it straight away that's really hard going well
you don't want to be doing any big climbs without that motor it is possible but really
you have to really really work hard dig deep because this is a heavy bike 28 kilos
braking performance now i have 30 kilometers per hour from this post here
actually for mechanical disc brakes we do have really good brakes on this so there are
zoom brakes and they do have quite good pads that really grip and bite into those discs
another braking test at 45
that took a little bit longer as expected because i was riding a lot faster but still good brakes
on this if i wanted to upgrade something i might put hydraulics on this but i don't really feel
like i need to they're not making lots of noise either these breaks which is really good so i
have quite a steep drop ahead let's see how these big fat tires are gonna handle it should be okay
not too bad and let's have a look at how the bike climbs up now bit of a technical rocky
trail that i normally tackle with a 29 inch it's actually doing a really good job at this
wow a lot better than i thought thanks to these extra wide
fat tires and they are just soaking all of this up i'm only running about 18 psi 15 20 is the max you
can put on these tyres and unbelievable look at this i'm climbing as good as i would on my trick
this is so good the climbing performance because of these tyres wow i am absolutely blown away
and now to go down all of these trails here down to the coast see how it does perform
so so far going down these trails very rough the bike is handling it
really well here just soaking up everything those tires the front suspension doesn't really seem to
be doing that much it has only given me about two to three inches of travel so i survived going down
that trail was a little bit rough going but it did pretty good considering what type of bike this
is it's not full suspension hardtail but it was those tyres they're soaking up all of those bumps
and then the range so we do have quite a large battery 13 amp hours a lot of the other bikes
i review are only 10 amp hours it's actually quite good thanks to the larger diameter wheels
so the diameter of these wheels in total even though it's 26 inch rims when you factor in the
height of these big large tires it's almost well around about 28 inches or slightly over
and that means for every 10 percent i'm seeing around seven kilometers sometimes eight so my
range is about 70 to 80 kilometers that i'm able to get out of this particular bike of course
the more you ride at higher speeds when you're not actually using the motor if you've limited
the speed to 25 that is you won't even be touching that at all so the range of course
is going to vary on how many climbs you have but overall i'm quite impressed with the range of it
it's not 110 which is their claim i think to get 110 you'd have to be lighter than me i'm about 82
kilos at the moment you'd have to probably weigh about 70 65 and be riding then on the flat and
probably the lowest power level to achieve that so i'm really shocked about how well this bike
climbs it rockets up these trails so that clip i showed you of me climbing just around here
i went out that pretty much as good if not better than i would have with my trek rail 5 which
is a bike that costs four times more than four times this particular bike right here so that's
impressive but of course it doesn't have the frame and the quality of my trek rail or the brakes or
the suspension that's a full suspension bike it's a complete different kind of bike here but still
this is an absolute monster with the climbs thanks to the 1000 watt motor top speed is also very good
once you get it into the seventh gear riding along i can happily cruise doing about 35 kilometers
per hour and that's great a lot of these bikes that i do review they have poor top speed
but i don't run into that issue at all with it now nothing really seems to rattle on the bike
until you go over some really rough terrain sometimes that chain will rattle around and
it has come off on me once over some really rocky bits now because these fat tires you only run well
maximum psi you can run on these is only 20 psi which is next to nothing they're super spongy
they just go over everything so well you're just bouncing along and i love the road noise
they make and it adds to that ride comfort so i really want to start to review more 26 inch
fat world e-bikes because i absolutely love this bike i think it is fantastic the screen is really
good it's nice and clear the front shock gives us about two and a half to three inches of travel
the brakes for mechanical disc brakes they aren't actually too bad so what does it come down to cons
then about this bike what don't i like about it well not a lot really i think the the battery
pack on the outside and then the controller is a little bit ugly and yes it is a monster of a bike
it's about 28 kilos i mean the battery itself weighs three and a half kilos so it's normal
it's going to be a heavy bike there but that's about it it actually rides so much better than
it looks it's very comfortable it's a large frame probably not a bike for everyone but if you're
about my height 182 centimeters even a bit higher and even about 170 this would still be a good
bike for you i've really enjoyed my time testing it out it's an absolute blast to ride so thank you
so much for watching my review here of the gogo best gf 600 a bike that has really surprised me
