72v 12,000watt enduro Ebike build! (Step by step explanation) 

Hey guys if you have any questions please ask I read all the comments and I usually get back quick. For more insight on what i do on this channel go to this channels Instagram @endoprysm.

how refreshing, someone who knows what they want to say and how to say it, no convoluted explanations of the obvious, I see someone who is going places.

I was looking for a video on someone building and detailing the process of building their ebike and I found this, here are the things I learned from this video. Pretty much everything is self explanatory and pretty easy.

Wow you're problay the Best E-Bike RU-vidr in this 5000w+ category FR. My 5kw ebike (with the same frame) is now nearly finished only the Motor still missing but i Know 2 months ago I had the same questions wtf do i really need I could fugure it out after 1 or 2 days but for someone that doesnt know anything about Bikes ect it problay would be a mess. Keep it up

I have a broken one that I have to put all the parts on another frame... I'm dreading it but seeing you do this just like you did helped a lot👍

Their you go this will help alot of people step by step that are getting in to mechanics an gives other a way better idea how to build a ebike

Awesome video, awesome editing, awesome commentary. Thank you

I was under the impression that the spot where you routed your brake line is where the controller usually goes on these frames, That's why there wasn't a hole for the phase wires. That said, also a nice option to be able to put it inside the frame as well if you don't want that box hanging off the front. I'd probably put the charger in the spot your controller is in, and just route an ATX female adapter to the outside (or some extra circuitry and an SAE J1772 female socket as well so I can charge at public stations).

I need this. I just stumbled onto your channel. Stoked.

hi im from Philippines, i love how you explain every step. one day i will build my own diy ebike :) thanks

Really appreciate the video bro. I've got a background in cycle mechanics but the electronics where intimidating me... Finally a clear cut video of how to wire the hub motor. I have new found confidence if I needed to do a tier or even full hub motor change. :)

You chose the same brake discs as mine and they are very good, they are also floating discs which prevent them from deforming when they heat up too much, that's what I had on my big cubes when I was riding a motorcycle, I did for more than 16 years, big unbridled cube... Tu as choisi les même disque de freins que les miens et ils sont très bien, ce sont en plus des disque flottant qui empêche qu'ils se déforment en chauffant trop, c'est ce j'avais sur mes gros cubes du temps où je faisais de la moto, j'en ai fait pendant plus de 16 ans, du gros cube débridé...

Great video, this will come in handy for my own build.

Thanks for all the content. It is greatly appreciated. Worth it weight in gold 😊.

Max one front disk brake adapter should be used. For example instructions from Magura are saying this rule. THANK YOU for great video!

You can get rubber grommets for the through hole you cut for the wire preventing the frame to chaff on the wires

You made one mistake when installing the fork. After sliding the fork through and adding the spacers on the steering tube, DON'T tighten the stem all the way, you want to torque down the cap to the star nut first. Once that's torqued, there's the right preload on your steering and you can then straighten the stem/bars and finish tightening them down. You basically want it to be able to slide around a little until the cap is torqued down.

You funny 😂😂 Loved the video thanks for sharing and hope you enjoy the bike! It looks great and looks like a blast to ride

I want to share a concept with you and your audience during your build process. The concept is 'steerer bearing pre-load'.... If you go to the fork installation section of your video, I would advise the following sequence: But first, a couple of things: 1. Always best to press bearing cups into the steerer headtube of the frame versus pound them in with a hammer. This is because the bearing races you are pounding into the frame can distort with hammer blows which compromises the interface aka geometric agreement between the bearing and the bearing cup(s). You can you use a gigantic C-clamp and a piece of 1" thick wood. Press one bearing cup into the head tube at a tim:. 2. Always apply a thick automotive grease or equivalent to the bearings prior to assembly. OK, this is the important part. Back to tightening sequence: The spacers on your headset are NOT just cosmetic. They serve a purpose. What you always want for stability and to mitigate damage to your bearings while out riding is...a concept called Brinelling...look it up....is have the bearing balls tightly against the bearing cup races to reduce vibration and damage to the bearings over bumps in the roads which put small dents in the hard balls over time due to space between bearing balls and bearing cups. For this bike build, the way to accomplish long bearing life is.... 1. Install everything except handlebar without tightening anything. 2. before you tighten the top 'tree' to your fork tubes, you tighten the skinny top screw which presses down on the steerer cap and compresses the top tree through the spacers and tightly sandwiches the top and bottom bearings between the two fork trees. 3. Now you tighten the top tree bolts which firmly attach the top tree to the two fork tubes. 4. Lastly, align the stem with the fork tubes which still under preload..knock it sideways with your hand...and tighten the stem clamp bolts. That's it. Now you have preload between the bearings and their mating bearing cups so when you go over bumps which you do every minute of every ride, the bearings won't Brinell and be ruined. But further, this is important, your bike will track much more steadily because the front end is tight...without any lash between bearings and bearing cups which promotes front end wobble due to road disturbances because without preload the front fork attachment to the frame of the bike is not solid. Hope above helps. You are a brilliant young man with a generous heart to share your good work with us. With your aptitude, consider going to engineering school if you love to build cool machines like this and learn about the relationships including why designs are created as they are. Thank you for your step-by-step video. Invaluable to anybody like me and others who has interest in building a very fast e-bike. Ride safe and have a blast!

Amazing practicial shop and engineering. Could really encourage kids to do Science Math , Engineering and Technology

Nice this is the video that i need for building my bike Thanx bro

That's something in the fork is called a star nut I do believe I appreciate your video I will be watching the rest of it😊

Super helpful! Definitely got a new sub

Fantastic job. Cheers.

Nice job on the video!

Drilling an hole?! I'm outta here.

Nice build & instructions. I need the build with the pedal assist version so it can be sly on UK roads (kinda!).

Wow pretty cool content dude! I like it.

Those tires look sick man, maybe add them to your disruption? Love your vids bro!

Hi there brother. I'm Leonard Erasmus,and i'm 50 yrs of age, and from South Africa. I must say that your ENDOPRYSM E-Bike is really awesome. To be really honest with you,is that i really do wish that i could afford one of your awesome ENDOPRYSM E-Bikes to help me for very easy and fast transportation to work and back home,but really unfortunately,is that i really can't afford one, because i work for the POST OFFICE COMPANY,wereby i really don't earn enough money to provide me with everything i do need really bad,and i also know that i'm not the only one.

Hope for the best .

I have the same model only 8,000w. I've found that the power to be too much most of the time. When I first got it I loved jamming around but for daily use it's like driving a Dodge Viper to the store for milk. I'm currently building a 2000w from an old bike for small errands and keeping the Enduro for long trips and fun.

This is the video is a life saver.

Your crazy boy ✌ Nice to meet you Im from Israel Thnks for video 🙏

This is the best video ive come across yet! Do you have an updated link to the frame that you used, that one looks amazing :)

Beautiful wheels

Just watched a few of your vids, that bike came out sick!! Quick question, did you buy used parts and around how much did you spend roughly? Also, did you have to register it to be street legal or is that not necessary because it's technically just like those regular rental ebikes?

God tier voice over bro. Been trying to do a voice over in my latest video but I sound so robotic when I try 🥲 solid video

Great video, good knowledge, few mistakes but great otherwise, especially for your age!

Such a good video, and 6:50 🤣 I remember laughing at that years ago

Nice! Good guide!

NICE! Subbed!

Omg she looks like a NASA moon bike 😍

Good job bro 👍👍😁⚡⚡

Liked and subscribed, good vid, cheers mate

Fast as Hell! Love the build series. What made you go with the smaller wheels?

great man, u r healthy future

appreciate your, im doing things exactly the same, ordered the frame, purchasing the motor monday, i may have questions

Love From Bangladesh🇧🇩

Love it mate

Frikkin awesome video bro

You will have a blast :)

I have the exact bike at home and I love it, But I bought it built with 193 miles. I also I have a 5000Watt Enduro

My build is coming along now still on the paint side of things at the moment

Good job👌

Nice one 👍

Nice Bike 🤩💯💪

For a step by step video, you mention “this is self explanatory” about a hundred times. So much for step by step!

Not bad for a 12year old. Just bugging you. Looks good. Video is excellent.

Good jobs ideas 👍👍👍

great video

Great vido very nowledge I no how to build bike now

I have a few questions on the build. 1: did you simply order a front tire in the same size? or did you do something to match them up? 2: does the battery you've purchased have the ability for the regenerative braking and did you have any problems with that? 3: (most important) does the torque/ power handle off-roading well? I want to do a build for going on trails through the mountains near me. many have uphill sections or rough rocky area's I'd like to make sure if I build an adventure bike that it can actually handle the load without burning up the motor. 4:I am 6ft 195lbs, would that frame and bike height feel comfortable to someone of similar stature? I've found many bikes are not the most comfortable to people over 5,11. thank you.

I liked and subed 😂 I have a question I have volimart 175mm will your qs273 motorcycle kit fit?

Dude! You’re the fukin man! thanks for your vids.

1. How did you made that white body? 2. Whats the total cost for making this EV bike? You did Great Job. 👌

Pretty sweet. You got me thinking to build my own. Is this the ''Bomber" platform?

I'm a 64yr old Retried Outlaw Biker. After a few sergerys and a couple yrs in the hospital I'm building a e- Bike next. Don't know why just like the tourk.

awsome video, wish i was trying to build a enduro now. but im looking to build a AWD dual motor dual battery setup on my kepler which has a 52v1000w1800peak motor @35amps 52v20ah battery, i already bought another battery two install underdowntube with aquad connector for two controllers/batteries. how to add front motor wheel with new contollers one display and one throttle and use of front or rear only or both. thanks if you cant point me in right direction. thx again

Awesome, this video has helped me out with my build 🙏👌

You can order rubber gasket for the key hole and make your own very cheap

Nice

So mississippi law is really loose/Grey. I'm beyond invested in this style, specs, and being stateside. Looking for 55-60mph for the roads near me but gotta have those pedals. These details for the build still good. I'm slowly coming up to fan boy status on your vids.

You're supposed to tighten the top cap into the star nut before the side stem bolts, not super tightly but enough that there's no play when wiggling the forks.... At least that's what I've always done.

thanks

Sweet video buddy, did the brake spacers come with or did you have to order them separate?

Front wheel and brakes as well as brake mounts? Can you please link would be very helpful thanks!

Ive wondered if a CYC X1 PRO kit would fit on the frame? I know its just 5000w but the gearing and pedal action sounds the most ideal for stealth. I have also wondered if one can be custom made with motocross strength in mind?

very good

does your frame have 150mm or 170mm dropouts? Have you thought about building it with a middrive instead?

What company or brand name did you order the frame? Also, I noticed you have a moto style seat. Did you have to modify the frame for that? Most frames look like they have a setup for a regular bicycle seat post. Thanks for your help and thanks for the video post!

Nope .it's not that complicated. Thanks for the info 😊

between the two bike builds, pound for pound what are the differnces between the two motor kits ? does the qs273 8000w have more bells and whistles or is the same as the qs 205 with the 5000w

Great video! Altough I've got a problem. Whenever I use my front brake the front fork starts wobbling. Any idea why?

Is there an alternate link for the fork and frame used?

Do you have to be careful not to move the brake levers and thus pushing out the pistons making it a nightmare bleeding the brakes do the brakes come or hydraulically filled with fluid and if so is any bleeding necessary to get them to be quite a nice

Can you change the grips on ten full throttle? To like blue ones ? Or do you have to buy the hole new throttle ?

Your work is somewhat crude but you will learn how to do it better with time. With having 16HP do you actually pedal this bike or are the pedals just for show?

Hey I have an ebike and the problem is that the rear wheel works perfectly in the air, but if I ride it on the road, it turns off after 200-300meter .

Is the bike a complete That you mod ? Or you gotta buy the forks frame and everything else ?

Have you ridden it since you put the new battery connector on it? If so, I imagine it performs better.

Did the spacer that protected the wires from the brakes come with the motor?

nice

Check out HI Powered Cycles novelty electric bike called the Typhoon Pro. 26x4 rear tire 27.5 in front. It uses a Hub drive but placed in the bottom bracket as it is a mid drive bike. I think it is the very best you can buy.

good man ovr

the front wheel it comes with the motor kit ??

Hello from Switzerland ! I did not find the frame...could you please help ? thank you very much. Congratulations for your job

Hey there, I love your videos. So, I'm looking at buying one and they told me since I'm 6' tall I'd be better with 21" wheels... I don't really like the look of 21" wheels. I would rather have 19". What do you recommend. I seen a video where you mentioned you where 6'1" and the bike was big enough for you... I think you run 19" wheels ?

Fookin dope

Where did you get the battery converter for the savion controller
