this dude builds THE DOPEST stuff with the simplest tools. *respect*

Some company should sponsor this guys with a quality TIG. It would take his work to the next level. Loving the build as always. I am looking forward to the next chapter!.

Even without having seen the final product, I can tell this thing should be mass produced. Awesome work!

@ mario - would not be a good idea, because the manufacturer will start cinching on material stating that it is good for the company to survive .

My mind got blown away the way you made the head tube bearing race🤯🤯

You're a god amongst men in the electric mobility community

I love that you aren't using fancy tools to make this incredible bike. Instead, you are just a wicked smart dude who can figure out how to make wicked awesome stuff with what you've got!

Thanks for providing this material, James. It is much appreciated.

I think most amazing thing about him is how he is building everything with simple accessible tools...don't get me wrong Pro tools are obviously good and makes life easier but those are expensive and mostly not accessible to hobbyist.Hardly saw any youtuber who actually does this level of high quality DIY builds.

I've been getting quite a few comments regarding the bronze bushings that I used for the swingarm pivot bar and why I didn't install a bearing kit instead. The answer is very simple - because bronze bushings are very rugged contrary to popular belief, and a lot more affordable than bearings. They're commonly used in low speed, high load/severe-duty industrial applications for this reason. These bushings in particular are from Fastenal. They're rated for 2000 lb/f of dynamic load and are self lubricating, meaning they're impregnated with oil so that as the bushing wears SLOWLY over time just as a bearing does, oil is gradually released to keep things lubricated so no grease nipples are required. A swingarm pivot bar is the perfect application for an appropriately sized bronze bushing. So why do most manufacturers use bearings instead? Another simple answer. The more replacement parts cost, the more $ the manufacturer is going to make from you after they sell you a bike.

A few humble suggestions for your design: 1. Keep the battery pack and motor as low as possible, possibly equal to the line at which the center of the wheels are, it would make a huge difference to handling 2. A storage compartment under the tank maybe? 3. A built in charger for the battery 4. Air channeling using plastic ducts from the front to cool the controller with forced RAM air intake, if the controller is mid-mounted 5. Vintage-style LED headlight would look sweet. 6. A strip on the inside of the frame, just like you did to reinforce the Triple tree stem, for additional support Good luck with your project! I'm waiting to see more!

@@shubhamchandra5417 1 - the motor is built into the wheel, and the battery will be set according to the ground clearance needed. Center of gravity will be the lowest it possibly can be. 2 - Maybe, if there is room. That area will hide the contactor, converter, and wiring harness. A storage compartment in the rear cowl would be easier. 3 - No room for a built in rapid level 2 charger, which is what I use to charge with. They're larger than most people would think. 4 - No channeling required. This is a naked bike, ie: minimal plastic fairings. The battery, controller and motor are completely exposed to direct air. Cooling is optimized. 5 - Not a fan of big round headlights, see the CAD at the beginning of the video for the LED headlight style I've chosen. 6 - No room - the battery is bolted inside the frame tubing, which adds rigidity. But it's not required anyway, the subframe alone is a steel tank and far stronger than anything on the market that's built with aluminum.

@@JamesBiggar I've seen the CAD for the headlight, I had already assumed you don't prefer Round Headlamps but said anyways 4 - got a point, it's fairly open and I just rechecked, it's just a 12KW motor, at continuous your controller can supply 240A/17.2 kw at 72v, so I'd go as far as leave the cooling alone, what's included should be adequate, even at your 24kw peak, which should draw 335A out of your 600A peak, though i doubt your 60Ah batter would keep up. Is it 10C? Then it absolutely would. I've got ideas of converting my existing bike (Yamaha R15 V3) to an EV with a built in charger and a 120v 10kw LiFePo battery, the problem is, in my country it's really hard to find a BLDC motor above 3KW, I need one that's at least 15KW, and international shipping is currently unavailable because, you know. Thanks for doing what I can't, cheers mate

Yeah, that's why I thought it was funny that you suggested I use another style of headlight, because I already made up my mind lol. But it's cool, no big deal bud. The battery can certainly take it. Custom built by Grepow with a peak current draw of 350A, 200 continuous. They can do even better than that for the right price. Affordable mid-drives above 3 kW are hard to find for sure. I personally avoid them because they take up battery space. Hub motor works great, plenty of torque and speed for a street bike, more than most conventional bikes in its class. But not always the best choice. No gearing = no options, wouldn't be a smart choice for a track bike unless it had a built in transmission. I've seen a couple of manufacturers working on such designs with axial flux configurations, but I don't think they're available to the gen public yet.

sir this video alone placed you on top of my watch list. i myself is in the mist of this project. im dealing with all the legal shit for California. im going to throw it out there if anyone can build a Ebike for less than 5 grand thats cali street legal. you will make a killing, Im willing to be a partner with a 100k investment towards a business op.

what a SKILL...... I'm wondering how to build headtube and how to keep swing's arm shaft in place.... this dude solves them like that! amazing

Great build, thank you for being a creator and sharing your builds with us.

i swear the way you cut the metal pieces are just absolutely godlike dude. fucking awesome stuff!

Grew up on a hobby farm. Dad worked as a heavy equipment mechanic during the day. Worked with him a lot when I was younger, fixing machines and putting them to work. Took an interest in woodworking in my early teens, got a summer job in construction. Worked that for a couple of years, 'barely' graduated high school in 2000, started an apprenticeship in 01. Got my red seal cert in 05, started a construction company a year later. Became interested in renewable energy and started experimenting with that in my spare time. Started the YT channel in 2010 I believe (maybe 2009, have to check). Didn't really take off until a couple of years ago - early content was admittedly crap. But things are going good now, I decided last year to do this full time. That's my story. The skills that I learned along the way definitely have helped here, but there was A LOT of research and head scratching involved to get to this point. Fluid dynamics, thermodynamics, mechanical and electrical engineering, etc - none of that was covered in the carpenter apprenticeship. Followed by a lot of mistakes. Building something from a set of plans is one thing, competently designing new tech is a whole other ball game. But if there's one thing that I hope this channel accomplishes, it's proving to others that if a simple carpenter can do this, anyone with the will and ambition can do the same.

@JamesBiggar

It's not the lumens that matter from a welding arc - it's the UV light. That's what causes flash burn. But, despite my attempts to convince complainers in the comments of the last video that cameras can't record UV light and thus the flash can't hurt their eyes beyond being bright and irritating, the comments still persist. People don't understand light energy very well it seems, but like to pretend they do lol. The loud scratching noise, on the other hand, shouldn't be perceived as sudden if paying attention and can be rectified by simply adjusting the volume on a person's device ;)

Generally that's true, but irrelevant given that standard cameras can't record UV light any more than they can record infrared - they have to be modified to pick up those wavelengths, otherwise they only capture the visible light spectrum. But I'm sure this won't be then end of me hearing about it. Such a silly topic to drag on. Anyone want to talk about the bike?

Why bushing instead of bearings?

@JamesBiggar

3 жыл бұрын

Bearings are overkill for low speed applications - that's why the headtube bearings are nothing fancy either. Just thrust bearings in Teflon. Bushings are ideal for high load/low speed or or high speed/low load applications - the right bushings for the right application will last just as long as bearings but for a fraction of the cost. This is why you won't see expensive bearings used in things like heavy digger booms. Low speed, high load, so they just use bushings welded to the ends of the cylinders. Roller bearings are best suited for high speed/high load uses, like a wheel bearing. A motorbike swingarm is a low speed/high load component. These bushings in particular are rated for 2000 lbf/sq.in dynamic load, far more than what they'll ever experience with me and a passenger driving in normal road conditions. www.fastenal.com/products/details/0435438

Superb build. Would be even better in alloy. Looking forward to you getting some "sponsored" upgraded equipment 🍻👍

I love your channel...

I want to learn from you plz make videos in parts which helps us to learn. Your are doing Awesome. ♥️ You sir.

I love how you block the weld plasma with y our logo!!! *_edit:_* Also ... I ride an all wheel drive electric bicycle. I have 2 separate batteries for each hub motor. I was thinking, you could do this on this bike if you halved the wattage of the rear hub motor, and used an identical wattage hub motor for the front wheel. Then you could tie it in to the same battery bank and still get almost the same performance. It also makes for much more fun when going through mud/water puddles that a one wheel drive bike would have issues with. I've won lots of bets with my setup LOL!!!

Good job.

Spectacular! Subbed here!
