Hats off to you for committing to that full long build of a mystery bike. Coming from a seasoned motocross rider and RUclips reviewer I cringe to see that suspension snap.
Loved the extreme riding to find as many as posible weak spots in your build. Not only a smart guy but also a serious bike rider. I hope you take care of safety and wear full protective gear while pushing your bike to it's limits. I look forward to seeing the build update and more riding from you
@@rainhodl3er72 You are right about the protective gear, I was wearing 60% bike helmet and 40% full face helmet before I saw the suspension snap and my brother ragdoll, now I’m going to always wear the full face.
I recommended replacing the swing arm bolt with a shoulder bolt if you can find the correct size, will make the bearing fit much nices and will likely last longer
No music. It serves ZERO purpose in such videos. If you need to listen to music when watching a video like this, then you truly are a complete slave to the Matrix.
Bro, such a well crafted machine, and the video was perfectly succinct. Could have gone even longer tbh. Thanks for sharing! Can I just encourage you to wear a fullface MIPS helmet? Speaking as someone who just got out of hospital for the 3rd time after a bad bike crash.
@@Calthecool My friend utmost respect for your build, but PLEASE, for the love of me, do not ride things like this on cheap Zoom forks and such. Get a proper rear shock, one for a pitbike or something similar and modify the mounts to make it fit, then buy a second hand boxxer downhill fork, you will not regret it.
Heyo, I work with high-voltage EVs and some stuff I feel like I should just mention as a safety. Please do NOT use solder on HV lines. The HV terminals are meant to be crimped. High voltage connection can easily get hot enough in some situation to melt the solder. It is industry standard to never solder these as it is a safety issue. I would also double check the bus bar size and thickness you are using to connect the cells together. Depending on how much current you pull through your pack, the bus bar (seems like you are using nickel or tin strips) may add a lot of heat you don't want. Very cool build and clean video! Keep up the good work!
@@XxBanziixX1 I now know to not solder those wires, although it should probably be fine considering they are big copper terminals with 3 gauge wire. The nickel strips are 8 x 0.2mm, which I determined would be good enough after looking at a bunch of forums, all of which gave different values.
@@Calthecool just because the wires can take the current without getting overly hot doesn't mean you wont run into a situation like the terminal screw coming loose and causing a high resistance fault that heats the terminal and melts the solder.
You haven't seen anything yet, the battery I make in this video can output the equivalent of 14hp, but people build truly insane packs that can output the equivalent of 80hp: www.reddit.com/r/batteries/comments/1dkubga/first_post_here_26s14p_p42a_936v_nominal_1092v/
@@Calthecoolhey try making simple arc furnace powered by those batteries using carbon rods for welding. It would be much stronger than simple furnace from wall output with the 12hp power. It probably will melt steel easily
@@Calthecool I used cheap Chinese arc welder (3kw) as simple arc furnace and it melts every metal but has a hard time melting steel and the steel hardens in crucible before it can be used. Copper, bronze aluminium etc melts really easy. I think using such battery as yours you probably could melt kg of steel and use it to make things for bikes. Like print wave metal castings for handles and such.
@@Calthecool That's perfectly fine, otherwise how to grow the channel. But, some RUclipsrs stop the video just after the build and then don't upload the next video for a month which is annoying. I personally enjoy the videos where something happens and then the result is in the same video. Anyway, hope your channel grows. Keep it up. Good luck. 🙂
To disassemble such batteries, you need to fill their plastic parts with acetone and wait 1-2 days, the plastic will become very soft, and the glue too, it will simply fall off the batteries. We did this when we assembled charging stations based on Tesla batteries. Also, you don't have to remove the fuses from each battery, it's enough to tear off the aluminum plate and the fuses will come off with it.

You get what you pay for when it comes to 18650's. That is such an important aspect of the build. For example I can really accelerate hard on my 7kw E-scooter it's pulls just as much as my camaro til about 20/30 mph, not to say it doesn't have top speed but E-scooters with road tires are INCREDIBLY SUSCEPTIBLE TO SPEED WOBBLE AT 60-70mph. "DON'T GET ROAD TIRES" I hit speed wobble twice and I wasn't wearing a helmet because I was just going down my own street. Anyway brother I have some High end LG cells I paid a butt load for but they make a HUGE difference in available power under load. I can go look it up if you want, let me know. Because your acceleration is looks to me about 3-4kw at best.

@@J1414R these big hub motors can take so much power and the controllers are efficient enough that it’s really better to just increase the power instead of adding gears. Plus the hub motor design is so simple that having gears would just complicate things. If I wanted to beat any surron in a drag race I could just build a 40kW monster with a bigger hub motor, but that would be ridiculous.
@@Calthecool hey, bro it’s just a a suggestion, a really good one, they could’ve added more power to cars to go faster but instead they gave them a transmission. Sometimes a single gear isn’t always the way to go, and shifting gears is fun too.

As much as this is an awesome video and cool project, homemade battery packs are a big red flag to me. Without a proper bms and safety testings, it's basically a fire waiting to happen. Be safe man!
It's got a BMS and it's all wired correctly. I think the cheap Chinese battery packs assembled by actual children are the bigger issue, and the people who buy those also tend to not take care of them. I only run this pack at max power for
@Calthecool personally I wouldn't use a bms that wasn't specifically designed for a lithium ion pack. Is the bms certified? Has it gone through proper testing? I have seen 18650 fires myself and they are quite scary. They release toxic gases, fire, and spread fast. Uncertified, untested Chinese batteries are also a huge problem. That's why laws are being passed requiring certification. That doesn't mean homemade battery modules aren't. Additionally it's not during use that scares me most, it's during charging. Does that bms monitor temps in addition to just voltage? Maybe its out of an abundance of caution, or from what I have seen with li-ion and 18650 packs, but At the end of the day I wouldn't risk my safety or my families with an untested uncertified battery pack.
@@yrguitar1 it’s made for lithium ion packs, and it has temperature sensors and a Bluetooth app that lets you check individual parallel group voltages. For the first charge I was constantly checking the voltage of every parallel group.
man i thought this would be one of those throw together a kit and thats it but you went way farther than that. good stuff man. how much current did turning the dials bring the sabvoton up to? ive got one but i went with the harder soldering same gauge wires outside the shunt to double the current
