For heat management you could always couple what gets hot to the frame. I'd wager the air passing the frame at the speeds you'll be doing will be plenty of cooling. If not bolt on a heatsink to the outside of the frame. It could look pretty cool!
I would also recommend that you put a few vents in the battery compartment. They don't have to be big just enough to let out gases should the battery starts to off gas.
I've built a few ebikes. Look at Kepler's Stealth Bomber. Internal controller was fine. Aluminium will conduct heat away and emit it without air flow quite well. Keep it sealed so you can spray wash etc. If the batteries need to vent, you want it closed up for safety. I recommend adding a remote key/alarm, and a decent horn.

I agree with others saying the aluminum frame will work as a great heat sink so use some heat sink paste between the esc and the frame. You also will want to Statorade the motor if you haven't already to keep the motor cool. Looks great so far and can't wait to see it in action!
Hello couple of things. 1 try using soap on your cutting discs for cutting aluminum helps cut. 2 you will lose power on a welder using extension cables. Also I do enjoy watching your channel.

You could make the bike suited for the road (cafe racer, naked, super sport). Just an idea to help with all the weight at the rear wheel. Keep up the great work 😀

Your center where swing arm is sagging lower. That's why the seat isn't lining up right. Put another block under it and it will line up fine. Of course you'll need to make another upper shock mount now.
That's exactly what I cam down to say. Put another block under the frame. of course it's going to raise the over all height. This is a going to be a big boy bike.

16:22 you live and learn. Fortunately, you're a smart cat. Each experience gets you closer to the final outcome. So it's not really that big of a deal if you remain within the limits of a rim motor.
with the possible cooling issue you could do an external heatsink through the frame or you could put some fans in the cover one blowing in and one blowing out with some ducts on the fans to keep dirt and water from getting inside
You can buy that cord on a spool in bulk and put your own ends on it. Might have been cheaper than two of those $200 cords. But since you have one already it would be cheaper to just add another. Either way getting the power inside out of possible weather delays is best.

@@bradley3549 making way to much out of it . Bury the cable run it in so you don't snag it . If you want cable when you leave pull it out. Extension cords suck not long term always in the way and are dangerous.
I think button head screws may be a better choice for the access panel, so your leg/pants are not prone to catch on the heads of the bolts while riding. Awesome project man!
Looks so cool! The unsprung weight will only really be a problem if your hitting huge jumps. I’m build a off-road 3 wheeler with no rear suspension the tires will soak up the bumps 👍
For a road bike a hub motor is fine, but off road the shock has a much tougher job trying to control all that weight flying around. Oh well, it’s still gonna be a blast!
One thing you could do at a later date is add a smaller hub motor to the front, Then have a 2wd bike Great for hill climbing Can be a small unit as it will be free wheeling most of the time and have a thumb throttle you can engage when in the tough stuff
Look up the * Typhoon * its a high powered ebike that uses a hub motor BUT stripped down and mounted as a mid-drive. So you could strip down that wheel and make it a mid drive motor
@@ShaunHensley you can bunny hop a full size sport bike I think you can bunny hop a 65 pound rear tire, it’s about the suspension and technique…. plus that they make lighter ebike rear tires. Trial bikes weigh between 150 pounds and 250’ish before fuel. Btw
@@AkPacerPilot When I watch trials events, I see them hop up a sheer face well over 6’ tall. Maybe you meant ‘trials style’ and not really a functional trials bike. Though even the style of bike has a super low frame, almost looks like a step through, so I don’t know where he’d put everything.
@@ShaunHensley I have two trials bikes it’s the technique and the way the suspension springs against itself to get them to hop like that, you wouldn’t need as big of a battery for it because trial bikes aren’t designed to go for a 20 mile ride, not on a 1/2 gallon of fuel. I think it’s possible, I think it would work.
Depending on how the controller heatsink is, just mount it so the fins are sticking out and seal it up. Or thermal compound it to the frame so that the frame conducts heat out.
You’re doing a great job for basically just a garage project. I have a Sur Ron electric bike and its controller is mounted on the outside. Look for an IP 67 rating. If your controller has that it’s waterproof. Almost every electric bike I see has the controller mounted on the outside, even ones that are not IP 67 rated.
A transparent cover door for the battery holder would've looked awesome & the inside of the battery tank lit up with some led lights would give it a Tron bike vibe.
This thing looks awesome, you really did an insane job of designing this frame. Loving the project and cannot wait for the next episode ! Thank you for the amazing content Chris
and not scrape on your knees, legs, on the bolts, they will dig into you, I realise there's not a lot of thickness there, but even a dome head would be better, triangulate the seat with the swingarm attachment and the top shock mount love your vids,
If you wanna see the sickest e-dirt bike on the planet, look up the STARK VARG (Stark Industries) straight-up Iron man's dirt bike, there on pre-order and they did a test ride with some pros from all classes and it blew there minds, 80+hp! or 20 if ya want. What you got there could give them a good run for the checkered flag and yours is pretty damn sexy too. I gotta get back to work so I can order one!
My initial thought on the outlet was why not just buy one of those cords and run it to the shed? Used one of those cords for my pull behind camper before I sold it, works amazingly and super thick a durable.
I appreciate how much you show the fabrication processes you go thru, as a Carpenter and habitual tinkerer myself, the journey (process), the challenge of "can I make this work" , was way more satisfying than using the finished project ... Not to say COMPLETING a project wasn't satisfying
I love what you do. I so wanted you to completely bevel the components on the swing arm to get 100% weld penetration. Good luck with your solution addressing that matter. I hope it works out fine. All the best. 👍
Your craftsmanship and ability to machine parts as well as you do is impressive sir, I wish I had your talent as far as the machining and ability to operate the equipment. Keep at it dude it’s badass

A second cord attached to your first one shouldn't be a problem. Just make sure you are using at least a #8 AWG (50 Amp rated) and preferably a #6 AWG ( 65 Amp) because of the extended length. Of course it all depends on the ultimate current draw . Glad to see you bought an extension cord though ! :)
It looks like the welder Chris has (he links it in the description) suggests a 50A breaker on a single phase 220V line and doesn't ever pull more than 40A continuously. At 100', even a 4 AWG cord will have a 10% voltage drop and only support 40A safely. I realize, that's a 24/7 rating for that size wire and welders wouldn't sustain that much current for long, so you could get away with thinner wire, but you'd want to watch things heating up when you're doing a lot of welding at once. The voltage drop would be instantaneous though, if that's a factor (220-22=198V with 4 AWG, more drop with 6 AWG and thinner). The specs for the welder on the website state a required input voltage of 220V +/- 15%, so the acceptable low end would be 187V. He could measure the voltage at the connection between the second cord and the welder's cord easily with a multimeter (while welding on high settings), to make sure he's still in spec. assets.bluesea.com/files/resources/newsletter/images/DC_wire_selection_chartlg.jpg
@@Sev_Auk In my experience, the china welders tend to pull far less than advertised. I bet he's more like 30a 220v continuous with the welder maxed out. That's 6,600 watts. When he was plugged into the 110v outlet it was only 1,650 watts. That's figuring 110v/220v instead of 120v/240v
In any industrial setting I've been in; They put the welder close to the power connection, and extend the weld cables. I'm not a welder, don't know if this is some cost saving thing, or if there is less power loss in the lower voltage higher current welding cables.
@@SteveEh That's by far less efficient (lower voltage/higher current vs. higher voltage/lower current), but logistically it makes the most sense because moving the welder around is a much bigger pain than dragging some cable.
I think vent holes are important especially if you battery goes critical and starts off gassing. However, it kinda looks like your frame is built entirely out of an aluminum heat sink. You could always mount the hot components with thermal paste and even add cooling fins to the outside if needed. Keep up the good work!
Maybe, bbut gotta be careful doing that. That would alter the rake and trail geometry. Possibly to a completely unstable condition (tank slappers, twitchy steering, etc..). Possibly it could be fine. But he did mention he was trying to match the original steering and suspension geometry so he wouldn’t have to start from scratch on the engineering for that, which I thought was one of the smartest ideas I’ve heard in a while. Rake and trail aren’t rocket science, but they are extremely important for a bike to work right, and different bikes for different purposes will prefer different specs.
Unattach the heat sink from the motor controller and bolt it directly to the aluminum frame, with some thermal paste in between. The frame will act as the heat sink and keep everything cool.
Awesome build, it's coming out much better than I thought it was going to. I thought you were just going to slap all the parts in the donor bike frame.
Can you use the aluminum frame with some thermal paste as a heat sink instead of a fan ? Maybe just cut a port for the cooling fins to hang outside of the frame with some sealant to keep the internals dry. Great job by the way, as always.
Hub motors like that would make a reverse trike an attractive option. Could be very small and "lightweight" electric 3wheeler, which is also 3WD and benefits from the round tire!
When done welding that body really need a mirror polish! it would look insane!.. look up Andy Kirky a UK youtube who has built some mad e bikes, he has used many controllers and overvolted a lot of stuff! love your project!..
Air to waterHeat exchanger on the outside and a little one on the inside with a fan seems the best option to me. if it’s rigged up right it will self siphon and not require a pump Though surely there’s a water cooled controller/battery that’s cheap
I am surprised you didn’t inset the rear axle blocks a couple of inches to spread load. Then plug weld or put dowel through the swing arm. Also the gyroscopic resistance may make it hard to lean or turn. The aluminum tank style frame can be used as a heat sink itself. Looks stout though. 👍
I think as long as you don't expect it to Perform like a dirt bike...it will never absorb rough terrain, land jumps, or handle like much lighter rear wheel. I guess not as much torque for climbing or acceleration as similar power mid drive either. I'm not sure I would trust the welds to take the abuse or have the rigidity of a proper dirt bike, it's more like a lighteeigt dual sport electric motorcycle that has some nice power and range

Best of all comments
@@SteveEh That's by far less efficient (lower voltage/higher current vs. higher voltage/lower current), but logistically it makes the most sense because moving the welder around is a much bigger pain than dragging some cable.
I think vent holes are important especially if you battery goes critical and starts off gassing. However, it kinda looks like your frame is built entirely out of an aluminum heat sink. You could always mount the hot components with thermal paste and even add cooling fins to the outside if needed. Keep up the good work!
Parabéns pelo talento e iniciativa!

As long as you aren't going crazy at the motocross track, I don't think you will have problems with the hub weight.
You do not need to cut or add aluminum for your seat to sit flush. Just drop down the front forks. Hope that helps.
Maybe, bbut gotta be careful doing that. That would alter the rake and trail geometry. Possibly to a completely unstable condition (tank slappers, twitchy steering, etc..).
Possibly it could be fine. But he did mention he was trying to match the original steering and suspension geometry so he wouldn’t have to start from scratch on the engineering for that, which I thought was one of the smartest ideas I’ve heard in a while.
Rake and trail aren’t rocket science, but they are extremely important for a bike to work right, and different bikes for different purposes will prefer different specs.
@@emersonb5764 tank slappers are pretty exciting when you first learn what it is 😂
Go to a hardware store, Buy the correct wire for 240V AC under ground and Conduit and Wire a 240 outlet into the shed.
Unattach the heat sink from the motor controller and bolt it directly to the aluminum frame, with some thermal paste in between. The frame will act as the heat sink and keep everything cool.
What I learned the hard way is that hub motors get hot quickly and cool down slowly
Beautiful
Awesome build, it's coming out much better than I thought it was going to. I thought you were just going to slap all the parts in the donor bike frame.
Can you use the aluminum frame with some thermal paste as a heat sink instead of a fan ? Maybe just cut a port for the cooling fins to hang outside of the frame with some sealant to keep the internals dry. Great job by the way, as always.
This thing is looking amazing 🔥
Hub motors like that would make a reverse trike an attractive option. Could be very small and "lightweight" electric 3wheeler, which is also 3WD and benefits from the round tire!
When done welding that body really need a mirror polish! it would look insane!.. look up Andy Kirky a UK youtube who has built some mad e bikes, he has used many controllers and overvolted a lot of stuff! love your project!..
A pinch bolt through each of the dropouts may help to keep them from spreading open, not sure. You got serious skills, that I know.
Air to waterHeat exchanger on the outside and a little one on the inside with a fan seems the best option to me. if it’s rigged up right it will self siphon and not require a pump
Though surely there’s a water cooled controller/battery that’s cheap
25:02 you should round the edge of the fork tongue where the power cable meets it. It will otherwise rub through it.
looking forward to seeing this thing rip
I am surprised you didn’t inset the rear axle blocks a couple of inches to spread load. Then plug weld or put dowel through the swing arm. Also the gyroscopic resistance may make it hard to lean or turn. The aluminum tank style frame can be used as a heat sink itself. Looks stout though. 👍
I think as long as you don't expect it to Perform like a dirt bike...it will never absorb rough terrain, land jumps, or handle like much lighter rear wheel. I guess not as much torque for climbing or acceleration as similar power mid drive either. I'm not sure I would trust the welds to take the abuse or have the rigidity of a proper dirt bike, it's more like a lighteeigt dual sport electric motorcycle that has some nice power and range
Gyroscopic forces plays only a really small role when leaning and turning. So no problems with that.
Oo
Good job bro👍👍
