I can relate to the 10yr old laughter while going 50mph on a death sled 😂 Definitely brings out the kid in us with projects like this. Great videos 👍🏼

can't wait to see the electric bike with transmission

You're waiting for it so: I found that totally electrifying.I was shocked at how fast it was.It'll be all the buzz at the meets.Now you have us all tingling with anticipation of the pit-bike builds.

On my electric bike the best addition was regen/e-brake. Even though it regenerates about 10% which is not much, but it saves me a lot of money I would spend on brake pads.

6000 watts is the equivalent of 8hp on that tiny bike. You're nuts Chris lol. The Pit bike will definitely be safer. Looking forward to more!

"The brakes don't work anymore" hits it again

Holy crap that thing looks fast. Imagine that with full fairings and a lay on the tank position and tall gearing, you'd be ready for a Bonneville Salt Flats Run. 👍👍🏍

Not going to lie. I was a little bummed it wasn't the second part of the "A Different Way to Build An Electric Dirt Bike" But... That was pretty cool seeing the potential of that new motor. Adding gearing to that is going to be an awesome little build. Good tests!

I also have that face of “joy” when I go full throttle with my electric go kart. That’s why I went electric, that feeling of acceleration is priceless. Looking forward to the electric pit bike build! Cheers!

If that motor can do that speed with those tiny wheels it's gonna do a fair speed on the pit bike, this has just got me even more hyped for the electric pitbike build 😃👍

Love to see you have another go at building a gearbox, this motor would do well with a two speed.

I watch the builds for years now just to hear your maniacal laugh when it turns out to be a monster. No different here, only this time it was one episode to hear it. Be careful, you're spoiling me, man. - aerospace engineer, retired

No helmet, no brakes. Good job!

Looks fun, Chris. I'm looking forward to seeing the pit bike run. To reverse the motor you can swap any two of the motor wires. doesn't matter which color wires.

Your Smile. That is what i am searching for. Building a Bike this summer, er soon as i get the funds.

Unreal doing that kind of speed on that type of bike running on wheelbarrow wheels 🤣😂 Really looking forward to seeing this motor on the other bike . Having gears as well will be awesome

Pretty insane man, going to work out nicely on that pitbike!

Bloody hell that looked fast.

For a little electric minibike that thing is insane pretty cool man great video great build👍🏼🤩💪🏼

Wow that’s awesome and fast 53 mph with the new motor that bike isn’t made for that kind of speed ! Thanks for letting me ride with you !! The need for speed

Omg that thing is amazing!!! I’m so tempted to see this thing with a torque converter

Your skills are insane!! Welding a sprocket man! Awesome build I love this channel!

I love your videos and learn alot each time I watch one. I used to race go karts in the '80s and we used a cogged belt drive. It's similar to today's timing belts on engines. They are so smooth and quiet, you should look into trying that. It would be better for on road vehicles though. Dirt and rocks would kill it.

Get one of those Solar panel chargers they use for fishing boats. Make a rear fender and mount it on top, would be nice to get a free charge on sunny days, thing is awesome!

Great job dude..looked like alot of fun

That is insane it looks like a heap of fun!

can't wait to see the electric pit bike ripp 👍

this look so much fun. props to you fam

If you end up putting this motor in this I highly suggest front brakes haha. Great build and definitely seems much better than your old 2k motor. Maybe a 4k on this would be a perfect balance

Glad you grabbed a brain bucket! 50mph is fast on those little tires 😮 good job as always 👍🏻

One of my favourite channels👍

I bet this would be even more faster with a gear box. Damn sweet project, made me smile. Nice video.

It looks awesome, maybe if you decide to buy another electric motor for that mini bike you should use the 48 tooth sprocket, waiting to see how the off road e-bike do on the trails!

You need to put a couple air ducks on the battery box that directs air flow directly to the electric motor and that will help keep the cooling down

Aww yea!!!! Sick build as always

Ive ben talking about doin this for years and wen this combo came out il i had to try good to see it can be done cant wait to see what it does with a gear box

That system works great on that minibike.

Wow that’s so fast.Good job.

Ur laugh makes it that thing even more awesome!

Love your slip on brake pads. 😆

Yip that is some good power for sure 😊👌 cool stuff allsome work 🌟🎉 the fastest little rascals ever😆👌🌟

i feel like the speed wobble comes from the handle bars sitting forward like that, causes you to over correct without you really knowing. just my opinion. SUPER SICK BUILD THO this is the video I've been waiting for, for these mini bike frames.

Great video Chris, I really love seeing electric projects from you, i know electric vehicles have some major drawback, but for for minibikes and go karts they are becoming a viable option. Maybe, one day we'll be able to buy wrecked Teslas for cheap to power our cross karts.

I just got a 24 volt 2500 watt forklift motor! :D

That's so cool allsome work from cruzermans inventions 😁🎉🌟👍👌 cool

Something my uncle taught me for every 1 tooth added in front is like 4 minus in the back or 4 in back minus 1 up front drive gear good way to figure things out I watch how far down the back as you do that the amp shoot up and the heat will double get a temp gun on the motor it will help you with the gearing it and the control can handle motors 225 top controler 200 less chance of frying it I like keeping temps around 180-190 tops and electronic last much longer applying this safety will also keep batt from blowing up watch those temps also save much money I got rc cars that are pushing 15 horse power with motors size soda can have little Pocket 4 wheeler with those little 49cc motor thinking of turning it into electric for my kids .keep up great work

53mph on little electric bike!! Thats crazy 😂😂 I can't wait to see how it'll goes with the transmission

That Lathe is awesome man

Wow! We love what your doing with our equipment dude. This is what its all about! Pro Tip: We have found that for a 10 inch wheel you can get maximum acceleration and still reach about 50mph with a gear ratio of about 5.7/1. This is about the limit of the motor but makes sure you aren't wasting an extra power to heat. 7.25 / 1 is best for torque on a 10 inch wheel with out being TOO short. Keep it up brother!

That looks effing terrifying lol awesome upgrade.

Ur happy laugh is awsome!!!😆

Awesome video Chris!!! Hope to see you at Pate's Swap meet!!! Would love to meet you someday!

always remember for wheelies - ATLEAST 1 FINGER ON THE BRAKES AT ALL TIMES!

You should get 4 of those motors and put them on a small buggy.

This is the future of transportation.

Chris you need to duct airflow to the motor thru and beside the battery case via scoops to cool the motor. Heat stifles electrons from flowing efficiently. You need some motocross pads. Those mini bike tires aren’t safe at those speeds. Check motor, wheels, and tires with Infrared thermometer.

wusss afraid of a little speed just yanking your chain Chris way to go Bud

Holy shit dude! Haha, keen to see it on the pit bike

LOL, I know that shaking feeling. They say it is addictive.

Crazy fast! 👍😁

You're so clever it's not funny. Always blown away by your ingenuity. 👍

Super cool. Don't know how comfortable I would be with that GoPro rod sticking out in front of me like that. Might get impaled.

If you want to learn easy, controllable wheelies, mount some pegs back by the rear axle. As for brakes, your speed controller is programmable. You should be able to program electric brakes into the controller.

Greetings from Texas. Great test of the 6k motor! Can't wait to see it in the pit bike. Okay, time for the dad talk... Please wear a helmet! Always makes me nervous to see you ripping down the street unprotected.

I was green with envy when Chris machined back the circular weld he'd used to insert the disc into the centre of the smaller rear sprocket. It was perfect in there, no encapsulated slag - nothing, just flawless steel on both sides. Will I ever be able to weld like that? Somehow I doubt it.

Drill air holes on battery box and do air vents from front to back to cool the electric motor

Just for Giggles put a Briggs & Stratton Flathead head on top of that electrical box😂

Great video👍👍👍👍

Tu é o cara, inventa os melhores transportes lol.

I would wear at very least something over your eyes before doing a speed run on any vehicle you create. yes a helmet is just as important for every ride, but eye protection when there are bugs, flies, and all sorts flying about. admittedly like 1 in a billion chance of hitting a bug, but you should see the mess they leave behind on my windscreen afterwards!! great video Chris.

Chris what the hick bro i was going to.say wheres your helmet but you did finally put one on!!!

I don't think that the brake pads are designed to work at those speeds, but it looks real fun.

Sur Ronster would be proud :)

Looks very stable at high speed.

From my personal modifying motorcycle experience I recommend going up a tooth in front sprocket and then down two more in the rear and I bet you this badboy will do highway speeds with ease and changing the front and rear will ensure you don't loose any out of the hole torque as you might if you simply modified rear only....

This definitely looks like helmet-speed to me :P What a crazy machine

Supper cool! I guess your angry neighbor can’t complain! 😜

Looks like a fun scary ride. Lol.

RBW doing electric bikes¿! Now this is exactly what I wanted to see from him.... I bet if he put a little more time into electric (build a custom frame around the motor and battery) he'd be hooked, I only know because it happened to me and I only got a Razor Mx650 and modified it. LoL Edit: I want an Electro and Co Motor Kit for my Mx650 so badly.... ❤️❤️❤️

Crazy Chris ascends to new heights of nutz

10:35 " Probably have to change the gearing" you said. Which way would you change it? A lower top speed or a higher top speed? Your test run looked great! 15:30 I found your gearing you did. Great job! You have all the tools and skills.

It doesn't matter which wires you swap. The motors work through pulses of voltage so you can't swap the wrong wire. Any will work.

Just because it’s quiet doesn’t mean it won’t kill you. Helmets are good. Gloves are good.

omg that needs front brakes, is so fast hahaa very nice

dude that thing rips xD

You'll never guess what I saw today, a dude on the tiniest bike going hell for leather the other way.

good to see you further your exp with electric its all trial and error.

love the videos. lots of skill in design and fab. and I don't mean to be a dick but that laugh man. not sure if it's a nervous tick type of thing but sometimes it's just too much for me to enjoy the content.

Neighbor won't have something to complain about that day.

Nice cop.helmet Chris!

Q: How do you keep bugs out of your teeth when riding a hopped up electric mini bike? A: You can't.

That little engine it's really fast and loudy too but it's seems incredible all right

It was a sad little bike but now its freaking awesome

I would highly recommend a set of Shimano mt-201 brakes

53 mph was the fastest I’ve gone on my old road bicycle. Long downhill with a 53 tooth front ring and 12 tooth rear. I gave up trying to pedal because I ran out of gear and was not putting any power to the ground. I can’t image going that fast on that little thing and I was running a narrow 20mm wide tire.

"Brakes are dead!" Goes full send. 🤣🤣

This guy's gonna Steve Irwin on these wild ideas

Like your work. Start with a little safety first and keep having honest fun.

That would be my luck it would definitely run backwards when I first hooked it up. 😆

Even testing get some glasses on. Just testing mine out I got a bug in my eye. Hurt so bad it was everything I could do to keep them open long enough to stop. And dont smile. Unless you need the extra protien, lol.
