I Installed the CHEAPEST 72V ELECTRIC CONVERSION KIT on Amazon’s CHEAPEST MOTORCYCLE ($260)
This is a whole new animal. Last video we bought
the cheapest motorcycle available on Amazon, but they didn’t ship to my house, so I bought it
on AliExpress instead. And last video we found out how slow and how unreliable this thing is,
even though it’s hilariously fun in its own way. So to resolve both those problems, I bought
the cheapest 72 volt electric conversion kit I could possibly find straight from China,
and today we’re going to put them together. Previously in this series, we unboxed
and rode this bike until it broke, which was 16 miles later. And when I got it
back home, I began tearing it down to see how much each individual component costs.
Here we go. One engine. Look at that. And to prepare to install an electric powertrain.
And it’s that time today. So let’s get to it. This is the electric powertrain I bought straight
from China. This is the cheapest powertrain you can possibly buy. All right. Battery pack.
Got the controller and we got the motor. Looks like it actually comes with
a rear sprocket and an ignition and a throttle. This is an all in one kit.
Check that out. Even comes with the chain. Look at that. Basically this whole powertrain
came as a kit. So once I mount everything up, the wiring should pretty much be plug and
play. This is a 72 volt 20 amp hour kit, so we should see a pretty significant boost in
performance over the stock powertrain. Obviously, I start with a rough fitment of the parts
to see which orientation works best, and of course to make sure it
will all fit first and easiest. I slapped in the controller with a self tapping
screw and some three M tape to secure it, and to reduce vibration to the unit. Next
up, I began fabricating the battery tray to get the battery pack mounted up. I’m
definitely not a professional fabricator, but it’s a simple process really, when
it comes down to it. On this project, I prioritize functionality over
appearance and just got the job done. To be 100% honest, I thought the bike’s bearings
were going to cover up the battery case anyway, so at the time I didn’t care that it
looked a little bit sketchy. Anyway, all the battery case needs to do is protect
the battery from impact and to be a safe space for the battery to sit and safely.
Next up, I began mounting the motor and I definitely approached it as well with the
mindset of doing it quick and functional. But you will see later in the video
I needed a rear support for the motor too. It actually had enough torque that
the motor was able to move just enough to keep popping the chain off. But all in
all, the electric swap is pretty quick and easy and this is a small project,
so it wasn’t overly complicated. But. Was. And with all the parts installed last step
is wiring. So Kurt rolled over and helped me with that. And we had it wired up and
running in like 30 minutes. It was pretty quick. There was a bit of soldering for
the battery leads and the charging wires, but besides that, the throttle plugged
right into the controller. The phase wires for both the motor and the controller
were color coded correctly, which was nice, and everything else that wasn’t color
coded we figured out pretty quickly. You. Just show the viewers the. It does
go pretty quickly, actually. Let’s, we need to strap the battery box in a little
bit better. I have it close. It does. It is 20, and then that’s crazy to me. In case
you some reason can back out of a spot. Super controlled reversing. Yeah, it’s
probably limited. Yeah. For sure. I mean, it’s just take off. Don’t have. Honestly. Yeah.
That’s not like if you didn’t want to be slow, you’re trying to lose out. Maybe don’t try riding
something that we’ve created. It’s right. I tore down the axle, did some tidying up and securing
of wiring, did a sweet fender eliminator and got the fairings put back on for one successful
electric swap on Amazon’s cheapest motorcycle. So much cooler. It does have a reverse gear as well,
and that’s the highest speed able to go. Let’s go ahead and get this thing on a
right. It’s definitely heavier than it was, but not it’s not too bad. Not too bad.
All right I’m ready. I forgot how tiny this thing was. All right, here we
go. The frick. Oh, it’s in reverse. Wow. This thing’s actually pretty fast. Holy
crap. I was not expecting that. It is totally. That is sketchy, but very fun
at the same time. It’s pretty. This is a holy one. Oh. Oh, dude, I gotta be
careful of that. I hit reverse every time. I’ll just give it, like, one solid rip and see
what happens. But like, it definitely is. Like cutting out, like stuttering right
out, like the bottom end. But overall, I’m glad it’s holding up so far. Looks like
we’re set to actually crank on a little bit. See what happens. Bro, this is so much faster. Oh my gosh. Yeah,
it doesn’t like it. Does not like the bottom end. Whoa. That was at least 30 right there. Just
on that little strip. That’s freaking wild, dude. At speed it doesn’t cut out at all. But
just on the bottom end, it does. All right, brake test. Whoa. That’s actually not bad at all. So much faster. How did it look? Just like up and
down the street. It looked quick. Pretty crazy dude. So now we know it actually works. I’m going
to get out on the street and we’ll get, like, a top speed pole and see how fast we can actually
get this thing. I’m going to go easy though, because this thing is extremely sketchy
already at like the 25 mile per hour top speed it originally had, but now we’re hitting
at least 30 or 35 just on this little strip. Let’s get on it high speed run
and see what we can get. Oh, what the frick! It’s in reverse. I hate that
dude. I hate that. Wow. Not a frickin. Oh, I just yeah, something broke. We swapped
it. There you go. What the frick. All right. And we once again are fixing the
chain, which just keeps popping off. Can’t have this be a thing, man.
There’s no way you can ride with a chain. It keeps popping off while I have
the chain off. I can actually show you guys how cool this motor is. I actually put
the ignition down here. Turn that on, and then give a single rip. Oh, are you.
Are you. Yeah. That was forward reverse. Low rpm. Low. Oh you do. We do have a chain. Indeed. All right, let’s
freaking do it. Haha. This thing is so much faster though, man. Yeah. High RPMs. This thing actually
boogies pretty good. Yeah. Looks like we’re tracking. All right, let’s give it a nice solid
pull here, shall we? Oh, this thing is sketchy. Really freaking goodness gracious. Oh oh,
oh, there goes our chain again. Freaking seriously. What, 27.1. So we roughly
have a top speed of probably about 30mph. Realistically. That’s insane.
Don’t mind me. Just ride my bike here. Well, I know we didn’t get a full range out of it, but we did at least get one nice top
speed pole. Honestly. Realistically, that’s all the time I have for this thing. As
much as I’d absolutely love to spend another three days trying to make this chain not pop off
on this crappy bike, I don’t have time for that. I got AF1 build to start. Okay. All right.
I’m going to go ahead and estimate the range on this thing. Probably would have been
about 20 miles on the current battery pack that’s in it. Top speed was like 30mph,
maybe just over that. And I think and this says it’s rated for 400 pounds of I
think I’m just probably too heavy for it. I’m like 210 pounds. And I mean, even on the
stock powertrain, like this stuff was bending back here. So take that as you will. I don’t
think that this frame was designed for a big person. But anyway, real quick we’re going to
do a price breakdown. If you want electric, convert this yourself. I did it as cheap as
possible and you know it is a functioning model. I probably just didn’t make
these mounts very well, and I think the motor was actually being able
to move a little bit, which is why the chain would pop off. So the bike cost us $381.40.
And I’m gonna just note here no insurance, no registration and very cheap gas. Like if
you can get this bike reliable on the stock powertrain that it came with, it would be a
very cost effective mode of transportation. And now the electric powertrain. We’ll start off
with the motor controller throttle sprocket kit that we bought. The motor and controller kit
was $136.56. That’s insane for like an entire powertrain, basically minus the battery.
The battery pack was $200.16. All right, so with this electric conversion, I’m also going
to add a miscellaneous. And I’m just going to for the misc, I’m just going to put $35 nuts
boards, welding sheet steel that kind of thing. Probably about 35 bucks. And then I sold the stock
powertrain for 30 bucks. When I removed it. Boom. Making some money back. Oh, boy. This is, this
is a lot more than I expected. It was. Well, this number was actually a bit shocking. Wow. Probably
not worth it in the end. After I see this number, $722 at $0.96 for this little
thing, and I’d say about two days, actually doing the electric conversion
if you generally know what you’re doing. So there you have it. Maybe that’s a great price
for it, I don’t know, I personally wouldn’t spend that much if I were to actually buy it and
ride around on it. All right. You guys. Well, that’s the full story of the $260 pocket bike from
Amazon, and I would have just rolled with a stock powertrain. Honestly, with electric conversions,
you get range anxiety and limited range. Like you can only ride these things for
like 20 miles tops. If you got to like, run a bunch of errands across town
and stuff like you can’t do that on an electric powertrain. So but with a gas one,
you can just go anywhere you want all the time, no matter what. So I would just
stock with the stock powertrain. But if you want a higher top speed and
reliability and you want to do electric, swap it cheapest possible $720.96 is what
you’re looking at. And about two days of your time trying to figure it out. The
next video you guys are going to see is the cheapest electric scooter I got for
like 150 bucks, brand new to my door. And then next up on the main channel, we’re
doing the last video on the McLaren and moving on to a three wheeled sport by converted
F1 car. And we’re building that out, so it’s gonna be a lot of fun. Stay tuned. Smash
that like button. We’ll catch you guys next time.
Sooo I installed the cheapest 72V electric conversion kit onto Amazon’s cheapest electric motorcycle! This really brought the bike to life. Should I do a follow up video for a full range test?
