Building a 72v Razor Scooter (3600w 40+MPH)

[@Calthecool]

Cost breakdown: Scooter - $50 Cells - $140 (adjusted for the time spent salvaging them) BMS: $30 Motor: $160 Controller: $175 Throttle: $13 Other stuff I can’t think of: $50 Total: $618 Also I just got this channel monetized, so run up that watch time so I have the budget to build more awesome stuff like this.

[@slimsqde7397]

so glad you actually rip on it at the end, i hate watching people build cool stuff then they ride it like shit. Sick video man your a real guru with this stuff

[@iBlaze69]

Guy knows his shit, respect

[@Calthecool]

I'm almost at a decade building motorized stuff like this, I have some experience.

They work great until you accidentally file your toenails 16:29

Insanely Underrated

@@Icantstophelp thanks bro

[@mermaster2342]

wow that thing is a beast! Awesome!

[@RANDOM-zc2bs]

Impressed by your work, who showed you all these things. Good job 👏

[@Calthecool]

It was a combination of taking things apart and watching KZbin videos. Check out this video: kzbin.info/www/bejne/iKKWXqt-ba6DnZIsi=UbPvIe10l6NYT5kr

[@elesinalex]

Totally jank and seems hella fun to ride. Love it The motor is so low, wow

[@user-bp5py6bh3g]

Sick build! Love your channel dude

woah! super clean..

been waiting for this vid to drop ever since ur comment on @BoostedRooster216 vid about his one. Very great vid as alwyas

[@designmas1713]

that is sick bro

[@Trailtested]

Great work and nice full sends!!

[@_North]

So this is where the extra cells went! Worth it!

[@Dudeface167]

Those donuts were awesome! Mine won't even do the tiniest burnout...

[@ReasonRaider]

No lie, $500 for a 5 year old sized dirt bike frame is crazy. I also heard that 200 volt electric unicycles are coming to the market, that is literally just a bomb in my mind but hey if they offer the fun they proudly infer it would be awesome.

[@Calthecool]

@@ReasonRaider Yes it seems like everyone wants to build one of those bikes now. I did manage to find one for $250 and build a bike, I just need to film more so I can make a vid. There are some crazy electric unicycles out there, I would love to ride one but I probably wouldn’t own one.

[@jamie-meanskunk]

Nice build, i’ve built my own version using a hub motor and mounted a couple of rocket motors 🚀 for fun lol

[@Calthecool]

@@jamie-meanskunk nice, Razor is actually making a new version with a hub motor, which I think is a good upgrade. Still SLA batteries though.

[@jamie-meanskunk]

@@Calthecool yeah, they definitely need to upgrade to a lithium battery makes more sense

[@Aidenlovsskyy]

You deserve my views

[@dabesal]

love the vids

[@Calthecool]

Thanks, I'm glad people are enjoying them

[@y0wl0o64]

You should really have more subs and views.

[@Damian-v3h7o]

I have built a kart from scratch with the kunray motor& controller kit (3kw) and 14s 8p li-ion battery. It runs just fine! I don't have any problems with the motor/ controller. My kart only goes 30mph...maybe I should try lower gearing too

[@GreenPlanet30]

Love it 🎉

[@austieoutdoors9763]

wow i have a red one of those dwn stairs but i have 2 high powered scooters one a solar p1 pro anyway so i need not try but sick video bro that was great i have a cheap 48v scooter with a seat on called a somethink goo at the end but i might do somethink mad with that

[@jeremyschultz4731]

that razor would be a death trap in snowy areas. plus based upon how low it is to the ground a speed bump would damage the battery housing. other then those glaring issues it is still a neat project i would not want to ride.

[@Calthecool]

@@jeremyschultz4731 I’ll try it in the snow next winter, although I don’t think people normally ride scooters through snow. You would have to go off a 3 foot drop directly onto the battery tray to do any damage, it’s pretty tough.

[@jeremyschultz4731]

@@Calthecool you will be surprised how many people ride a razor type ev in the snow to work. just look up off road razors with hydro breaks. then if it has an raised suspension shocks, meaning it is raised higher then normal odds are the said razor type ev will do okay in snow. Aventure.2 Ebike is an example snow safe ev bike... with hydro breaks... people in my area use it all the time. my area can see 4-5 feet of snow some winters in my city.

[@jeremyschultz4731]

@@Calthecool people to ride ev razors in the snow more then you may realize. also you need a fat tire ev, if you use an ev bike to safely handle black ice. razor wise, you need to get an raised off-road class ev razor to safely do it if you want razor ev like brands names let me know.

More bomber content!!

[@BekzatAman-ds5zm]

Не вариант чуть увеличить самокат? Приварить что нибудь, и еще руль чтобы под углом на себя где то на 85*,80* Гадусов, вот тогда управление легче и устойчивее будет

[@Calthecool]

Yes I thought about that, but it would put more stress on the steering bearings and it’s good enough as is.

[@mrWantsMx650Parts]

When people put the controller on the side it makes me wanna die

[@Calthecool]

@@mrWantsMx650Parts yeah it sucks but it was the only place for it. The one in the next video is behind the rear wheel, it looks much better.

[@KirstenMach]

Nice i built a 5000w 72v razor e300 with a zero 11 motor and battery

[@Calthecool]

@@KirstenMach sounds awesome, I would love to see a vid about it.

[@ianreed4636]

Like your neighborhood.

[@Calthecool]

Yeah we are in the process of getting new streets, this street is actually a few blocks over. Our street is currently just a bunch of mud.

[@fotisxevgenis]

you should really incorporate a 3d printer in your builts it will help a ton for custom casings & etc...

[@Calthecool]

I've been thinking about it

[@fotisxevgenis]

@@Calthecooloh its a no brainer a bambu lab p1s/p1p for quality and reliance or an elegoo neptune for bigger volume

[@markcozzie]

Please don't move on to anything anyone else ride or drive,someone take his tools away before seriously hurts people

[@MikeTwohey]

What was the rough cost?

[@Calthecool]

Check pinned comment

[@gunginga]

wouldn't a rear hub motor be better? it may give you space for the controller and you wouldn't have to worry about a chain

[@Calthecool]

Mid drive motors have much more torque, but hub motors are definitely better for riding a scooter normally.

[@TheRealRazzyDazzy]

DUDE you should link the cells and make a video on how to make a 72v battery around 8000watt if possible or sum i really wanna make this electric bike and have been wanting to learn for AWHILE

[@Calthecool]

@@TheRealRazzyDazzy is it for a stealth bomber clone?

I have some scooters need fix how much you charge to rebuild one

@@josejuan1264 Unless you are in Kansas then it would be better to find someone locally.

[@jonathannguyen672]

you couldve just used a vice to take the drum off and but. a disc brake adapter on

[@Calthecool]

@@jonathannguyen672 I didn’t know those were a thing, that’s pretty neat.

[@jonathannguyen672]

@@Calthecool yeah, I suggest getting hydraulic brakes too, that scooter is gnarly!

[@Calthecool]

@@jonathannguyen672 I really only use the regen, I only need the disk break when I need to stop suddenly so it’s good enough.

[@oazywtf]

bro why dont you rebild theses scooters and sell them for 800 or something

[@Calthecool]

@@oazywtf I’m going to list them both and see if there are any buyers, the problem is that I live in the middle of nowhere so there’s not much of a market for stuff like this. This scooter wouldn’t be worth it to build and sell, but the other one would if people would pay like $600.

That's a nice e300 build. I saw someone else who has one build with flipsky motor but didnt show vidoe only YT short for smaller motor and smallee controller in flipsky parts lmaybe lookn into it tell me if is worth it

[@Calthecool]

I would say that this one isn't worth it, but the one I built in the other video is worth it for sure. I still ride it a decent amount and it's still fun.

[@ClownMoney]

@@Calthecool I still can’t believe you fitted that brushless motor I have 2 e300 thinking of maybe doing this. I will stay at 25mph mark

[@Retrograde99]

12:10 unfortunatly these kits are known to burn out the motor the motor gets way too hot and then it just melts on the inside at least that is what I have seen happen to almost all that I have seen

[@Calthecool]

@@Retrograde99 huh, that sucks. I’m definitely getting my stuff from econic cycles from now on, it’s only a little more expensive but it seems higher quality.

[@Retrograde99]

@@Calthecool yeah defenatly higher quality you just have to look a little further than the nose can reach sometimes tho it is possible to keep these motors cool you'd need to put in a lot of work to do so
