Cecil thanks so much for the info I'm getting the BAC 4000 controller gonna order the 72 V battery soon and I got the super moto tires coming along with the gates belt. So thanks for testing thanks for doing all the hard work! Perhaps I can provide you with some data when I get going? Anyway, back in the day, working on a supercharger project for an OEM we were stripping the cogged belt all the time gotta bave really good tension like you said which also affects over all friction but you want to keep the vibration down may be your motor speed is higher and that's where the failure occurred at higher pulley speed? Many supercharged manufactured cars get a nice wide serpentin grooved belt so no cogs but grooves and that really improves the belt life although you may get some slip at launch. If you work with Gates like I think you are, they could really hook you up. Thanks again keep up the good work, as it does get expensive!
I had a Whizzer Sportsman to get to school and work when I was 13. It had a Gates belt too. V Belt that was used as a slip element in a clutch. I carried a spare all the time. I think you anticipated belt carnage because you have so many spares. Not much changes in 64 years. Nice work on the Sur Ron so far. You will have to be careful with the front end. The last thing you want is speed wobble on that little bike.
@@geneafrica6795 after everything I was in about 8000. But subtract 1200 because I sold the stock controller and battery. Ended up doing the belt drive too and absolutely love it
You need a belt tensioner to keep it uniform as the wheel goes through suspension travel unless the Angle doesn’t change at all , you don’t want to ruin pulleys
Hi jack, As you increase the wind resistance is your biggest enemy. I heard somewhere that getting cars to go over 200mph wasn't just hp but aero dynamics become the main factor. Your body is a huge problem and i bet just turning sideways would be better lol. But really you are crushing it with a sur ron. Good luck sir.
I would imagine braking from high speed in a short distance is sketchy with as light as it is. Almost like the feeling you get on a sport bike when you bite off more than you can chew hitting a sharp corner.
With 20s hv lipos 🥰 for example tattu rline, or CNHL blackseries. They are made for Drone Racing. You can build a very light, high amp output battery pack for dragracing. They have 150C Rating. With a small 5Ah pack you can pull over 700Amps at 84V 😳 thats 58KW 🏁🏁
@@swissuav9273 Bro As a top 50 ranked MultiGP pilot I can attest those batteries are garbage. Crapttu and China Puff Line are the joke for drone races. Even guys sponsored by those companies run other manufactures lipos with the stickers swapped. Tattu R line are a B- battery at best but cost 30% more than batteries that outperform them.
@@cyumadbrosummit3534 i had very good ecpierience with them, but myabe im not pushing it hard enough. 😬...but for the sur ron bike its plenty. I doubt the motor can handle over 50kw. I like the idea to have lipos instead li-ions. Lighter with more power output. Also mutch faster recharge. A sur ron with 84 lipo volts, with the asi 8000 and full blown motocross setup, forks, brakes just everything for serious mx track performance is what im dreaming atm. 🏁
It maybe that the belt stretches a little under that load and then is slightly looser. Then the load is on again after deceleration and bang it spins . Best to keep a watch out when giving it a squirt. Accelerated stretching. Wont be much though . Maybe increase the drive sprocket diameter a little will make a big difference!
When using a chain,there has to be a certain amount of "slack"..which is taken up as the rear suspension compresses and the swing are extends,how does this work with a belt,if it's under so much tension?...also,are you not putting a lot of stress on the bearings?..no expert myself,just looking to learn..thanks.
did you have to get insurance and a license? I'm trying to understand the ebike law and decide if I should order the pedal kit, which I don't like but might have to so I don't get in trouble.
can you explain how battery voltage works? you got a 72v battery but when you showed the battery percentage after the run the voltage was something like 80. How does this come into play when tweaking the controller? I've got an electric scooter out here in china and im trying to figure out the max i can push my current 60v battery is but also just placed an order for a 72v. Thanks in advance!
It is interesting to see the speed but my self l m interested in distance any chance you could try 72 v battrie in standed sur ron for distance keep it up !
I got segway x260 it goes 47mph and i wanna upgrade it to go about 60 can if i put bac4000 on stuck battery will it work i dont wanna change the battery n controller i just wanna change 1 of them to put extra 15mph on top of my 47 any suggestions???
2 Q. I have luma belt kit where can I get the bigger kit ? Have you found socket to fit swing arm pivot or just use the Luna wrench. Thanks brother keep giving it hell ✌️
Not sure where to get the bigger kit. It’s in another country. Look on endless sphere. For the swing arm i just use needle nose pliers to hold it and an impact gun on the other side.
@@JackCecil What are you using for the stabilizer and have you changed headset bearings or wheel bearings? You're mostly road riding but I turned my wheel bearings into little chunks of welded metal dust after a thousand miles. Nice work on your build.
Man you broke so many laws then posted it to yt! You're brave. I was busted for a drone video in Australia, cost me a lot. If I rode an unregistered bike never mind the rest then posted it they would lock me up... I'm jealous:( Goodonya mate 🦘🦘
Except for noise reduction, I see nothing but disadvantages to that belt system, specially for off-road. In fact, looks like for off-road, I'd swap the primary belt for a chain.
I think I'd be happy with the whole setup minus the battery, just the controller for the extra power , the belt upgrade and brake upgrade and the same tires and I'm good
@@eastcoastgaminq4399 So, it looks like you could go up to the bac 4000 with the 60 volt stock battery? I want the bac 8000 which means upgrading the battery also correct?
@@dasppg9737 Nice! I'm looking at the same upgrades...If i want to run the stock battery at first can I use the bac8000 or just the lower 4000? Still wating for the bike til mid to late June....damn!
All you need to hit 80mph is to have a reduction of weight. Anyone who can optimize the controller unit in conjunction with the 72V battery, the belt drive, rolling resistance (smooth tires), simply be less than 150lbs, and no headwind will kick 80 easily. It’s all physics power to weight ratio at this point if the mechanics are set in place correctly.
Jack Cecil, so what you’re saying is that this bike will top out @77MPH with no rider, counting the aerodynamics (headwind/tailwind)? Essentially the power to weight ratio is not a factor in the current configuration of the drivetrain? That would mean the battery a has a limiter, and the only way to get around that limitation is scaling the power distribution which you have been doing. If so, then it’s simply a matter of ramp with the proper algorithm, not linear power over trial and error. 😀
You got there pretty dam quick too, good machine, would love to get one, I'm just waiting to hit the right scratch off lottery ticket,lol, they are the tits!!!🔥
Jack Cecil I’m looking for a daily commuter as well. Need to be able to travel about 30 miles round trip with some hills, be able to hit speeds of 60mph or better... this look promising! Thanks for posting!

When debris, stones, off the front wheel gets between the grooves of the belt also causes damage to the belt.
Wow!! insane!! Stealthy power...that nobody would expect from a bike...im lovin it
Love the content. Can’t wait to see it on the dyno

Isn't that kind of tension hard on output shaft bearings? Also tension could increase with suspension travel

Awesome speed. I'm more into the 0to60 numbers personally. That fast acceleration is the fun stuff
I’d like to get a larger rear sprocket for the belt to accelerate better.
WOW that's impressive man 💪👍👍💯😁
How does the width of the tire affect the handling the faster you push the bike. Does it get squirrelly after a certain point?

What?
I’m not looking down.
Pretty sure hes just tucking. Like you do going fast on a motorbike.
can u put a rundown price on the upgrades? like controller and battery? i was interesting in dualtron scooter before, now i want one of this.. :D

Are these things water resistant or anything?
How much for the 72 volt battery and controller
That is insane fast
The moment when your modified sur ron gets faster than my 125(equivalent) electric motorcycle (em etrek 9kw) Well done sir (ron)

First time seen this video, and I'm pretty STOKE! My question is the price of that E-Bike exactly the way you have it; all mods. Interested in buy.
Diony De Jesus its over $5000 and that’s not including the 72v battery.
Around 7k as it sits.
Well I'm my opinion it's worth it, 7k because a Specialized or Giant etc. Cost between $5,000 & $8,000 up.
