Stock Sur Ron X Top Speed Test VS 54 Tooth Sprocket + Range Comparison 

We are giving away a Sur Ron X!!! www.grindhardplumbingco.com/

16:00 is the actually top speed test. 19:42 is the results / numbers.

Wow! Watching you takes me right back to high school (1966-1970) and my little 125 dirt bike. I'm a disabled army war veteran (desert shield/desert storm) and don't really get out that much lately......but your videos make me feel like I'm right there with you. It's truly a good feeling and I appreciate you taking me along for the ride. Hope you continue to put out these high quality vids.....it's nice to "get out". Take care.....new sub here. Keep on rockin, Edwin! From Columbia, Missouri. Home of the Mizzou Tigers.

For those looking for more Top-End Torque for the Sur Ron, the 52T Rear Sprocket will deliver. It adds 20% to the Acceleration and Hill Climbing while taking the top speed down from 45mph to 38mph! So a bigger Sprocket means more torque but less top end speed!

Love your videos Edwin, we are only 8 and 12 but the sur rons have givin us more confidence to try new things on 2 wheels 😬

Thanks Edwin, Great Video. I'll be upgrading to the 54T this week! Cheers.

I’m definitely getting one 💯 these look amazing great fun😎 thanks for sharing

I can clearly see the difference between the stock form and 54t. Its a whole new bike. Man great video as always. Hope and praying to God that I win the sur ron 🙏 🙌 😞

I've tried almost all of the sprockets available on my SurronX and at 185LBS rider, I like the 58T the best. Still fast enough for the trails but also enough power to get me up steep hills. If you weigh a little more then maybe go with the 60T and if you are 165lbs or less then go with the 54T. In my opinion, 64T takes away too much top speed so I would not recommend that unless maybe you are 240LBS or more and need it to lug you up hills. In my opinion, the 52T should come default as even with a really light rider its great over the 48T and especially if you are woods riding you don't need to go 50MPH on this little bike. Now if we could mod this bike to have two gears, at 185LBS I'd go with the 64T and the 54T and normally only use the 54T but switch to the 64T on really steep hill climbs. In a perfect world, this bike would be 72V, 52T sprocket and about 12HP vs the stock of about 4HP. You can do that now with some after market mods but i am looking forward to when that is stock as this bike would be amazing in that configuration. This bike is a blast! Loving it especially on the tight trails. Battery technology is really the limiting factor these days but that only going to continue to improve and eventually electric bikes will take over motocross. If you have not checked it out yet, watch some videos of the Surron Storm Bee full size dirtbike. Looks great but may be just a bit too heavy thanks to that huge battery for some. One day you could replace that battery with a lighter more powerful one and make the bike even better. I believe the controller can handle 150v on the storm bee but again today's battery technology is the limiting factor since a 150v battery would just add a ton more weight to a bike that is already borderline too heavy. I'd bet that with a 150v battery the full size storm bee could compete with 450cc bikes if we could keep the weight of the bike under 250LBS and if the electric motor can handle it.

This snow test is great for me, being from new England. Thanks!

What an seasons video man, subscribed brother 👊

I could visually tell the difference in this footage on that new 54T. Especially off road the bike looked more alive than it was stock. Nice battery improvement too. In warm weather that bike will see some good range.

The trick to wheelies is sitting back on it and really hanging your weight. Thinking about keeping your arms straight will keep you from leaning forward. But you need to get good at covering the rear brake to do that, otherwise you'll loop out every time. This is at least what I figured out learning to wheelie my mountain bike.

Sweet, the 54t is in the mail! 👍🏻💯

Great video Edwin!!

Jesus, finally the video I was looking for! Thanks

Love your work! Thanks!

Okay, 38.5 mph is still hauling ass. Love your videos man.

I just put my 54T on yesterday. Haven’t tested the range yet but I like the performance much better already. Debating ordering a 60T to try.

livin thru u bruh..thankx for the vids an info

My new Sur Ron is arriving tomorrow, along with a 60 T sprocket. The trail I ride is so rocky AND steep, besides needing the torque to make the grade, I also have to do it slowly. I may even go 64 T, loss of top speed is not an issue. Good info!

It’s so nice living in sandpoint. I think I saw you one time

I love this channel keep growing 🔥🔥❤️

I'd be happy w/ the weakest base model of one of these if someone gave it to me at a decent price.... And when people upgrade the the bigger battery and the BAC8000 controller, do they swap out the motor too cause I'd love to have a motor like that in my electric pitbike.

The reason for the spedometer reading inaccuracy is probably becausethe speeding is read from the output of thoe motor, so the motor can still be spinning the same speed if the gearing is changed, its just the wheel isn't

The bike's speedometer is based on the motor rpm, so, theoretically, since the motor would spin the same speed with the different gearing, the speedometer would read the same.

wonder what could Sur Ron X black edition supper moto conversion do with this. and how much could go luna edition 72V tuned with bigger battery as supper moto and belt drive.

I believe the speedo is connected to the motor controller and not to the wheel. That's why it was reading the same during the two speed runs. I'm curious to see what sprocket combo you go with on the new controller and battery.

I'm looking to hopefully pick one of these up next summer, appreciate the good info. You mentioned it, but yeah keep an eye out for photographers and fishermen on those creekside trails, especially early like that. I like the stealth factor of these bikes for sure, but we'll never hear you coming, haha. Keep it up!

Why not more then one rear chainring, and a strong derailer?

That's Hella fast; I have an 08 CRF250R with an Athena 280 big bore kit from the guy I got it from and THAT THING GOES 70 It's insane since it still has a bigass sprocket on the back --I don't remember how big anymore

Have to change the chain or remove/add links for a 54T ??

A two speed transmission might be a great benefit.

When are you going to fully build the bike?

Nice vid I love my surron and I want to start putting mods where did you get your new tires? Thanks

I got a 64t to try. Got got the bike yesterday love it

AWSOME video!!whats one cost & howlong charge last

How many miles of range can you achieve while averaging at 25-31 mph on flat road (commuting to the work, city) with the default sprocket that came with the bike?

I had put on the 64 tooth sprocket on my SR X and I was greatly disappointed. My range was almost cut in half and I did not notice too much extra torque. My top speed was around 35-37 mph. My weight is 230 lbs. and I had a non o ring chain on it. I just could not figure out why it was like that. Went back to my 48 tooth and I have been much happier with a top speed of 49-52 mph. Cheers.

You were able to change the sprocket and not have to change the length of the chain?

Do I need a bigger chain or can I use the same 102 link?

Link for the gloves ?

Did you have to change or add more links on your chains or the stock chain work with the 54t sprocket?

much needed comparison!!

Dumb question, but… do i absolutely need a new chain with a 54t ? Or can i bring the adjustement all the way to the front and make it fit? The bike is new, so is the chain, dont wana replace it for nothing

CDA Area? I lived there for 15 years.

Hello I am around 65kg very light but wouldn't mind even more torque but not loose really any top speed what sprocket would you recommend

that skate park looks fun

"So, let's cut the music.' Awesome, that is 'music' to my ears. There are too many videos with a deafening soundtrack drowning out any chance of hearing the narrative. Good vid, I have an XL1E on order with an optional 58-tooth sprocket and 112-link chain but it won't be shipped until May.

Do you need you motorbike license for these? Great video. Every new video you fo on these I want to get one more and more...

@edwin olding what size chain did you use with 54t

Can y'all fix the fisheye lens make it widescreen cuz it's obnoxious and makes us dizzy

is the top speed in mp/h or in km/h?

Is the top speed with the safety wire cut?

Can you pedal it like a normal pedal bike if you run out of battery? If so will it charge wile pedaling?

How long dose it take to get delivered

I gotta get regen on my '52 Roadmaster hill climber ev bike. Sur Ron should make an AWD version my budget bike motors climb almost as well no shocks. 32mph top speed.

Just wow..I won't sell my street fighter but dayim this looks soo fun

Love this Channel

So whats the top speed of the bike in kilometers

Does the SurRon fit for tall riders? 195cm / 6 Feet, 4.7717 Inches

Is there a Port/Accessibly to add a Portable Battery Pack in "A Pinch"? What Voltage?

Yooo Edwin, which action camera are you using for your riding shots? The low-light performance you get out of it always looks so crisp!

That snow tho😍❤

Possible two or more per tire

Yewwwwwww

Wheres the best place t buy a sur ron? As far as price and shipping fast. Thank ypu.

Out early getting it done, and it even looked COLD!!!

If Edwin rides his Sur Ron and mines crypto in his free time, what does Ethan do?

good vide. did you adjust the chain length with 54t ?

Speed is calculated by controller. It checks how many turnovers front sprocket makes. If you change size of wheel or sprocket, controller will show incorrect speed and odometer. More biggest one of them will increase speed on display, but in real you will move slowly.

How much do you weigh?

Love the videos! Hows the suspension on it?

Why would the app tell you what percentage of your speed is off? How would the app possibly know that? If youre using GPS youre not really accurate at all

Im getting a surron in couple weeks

I just put on my 54t and i feel almost zero improvement - not worth losing the top speed. Only getting 37mph - 😞

larger sprocket on the rear gives you more torque and less speed, smaller gear in the rear will increase speed and lower torque, as for power consumption the higher torque uses less horse power to propel the bike, going with a smaller gear will use more horse power to keep the bike in motion at the faster speed. the gear ratio plays a big part in balancing the power for speed vs the torque for climbing and starting from a dead stand still, as well as power consumption. some where between 48 teeth to 50 is probably the most in efficiency, dropping to a 46t or going up to a 50t might give an interesting result. any more than that may compromise electrical power efficiency.

Have you seen the video of a guy shredding a sur ron on an mx track? Its pretty impresive

What chain size do you need for the 54?

The computer is calibrated to the stock sprocket, so the reading will be extremely off when testing the 54T.

Is the bike stock other then the gearing obviously

Hey check out jack cecil on youtube. He has a sur Ron x with belt drive and modded battery and controller and if I'm not mistaken his sur Ron has hit 70 to 80 mph.

I can put this 54T sprocket using the stock chain?

Have a sur Ron is my dream

thanks for your help with me all brothers and subscribers 👍👍👍🙏🙏🙏🤝

If you installed a system that could swap sprockets mid run you could technically have the best of both.

Awesome

Dang how are you getting up to 49 MPH on a stock Sur Ron X ?? My top speed is 31 MPH on mine but I do weigh more than you but still should be able to hit 40 at least ??? Weird...

Did you cut the green wire or just complete stock

Don't knock yourself so much about riding in the winter. Best time to be on the trail when there is no one else around.

Sick bike that fast for a bike would you need a bike license for that

Nice bike

9% = top speed difference = battery usage difference. So while sprocket gave different battery life its most likely just due to top speed.

I really think a 50-52t would be the "sweet spot" compared to stock. Every inch makes a difference as do teeth 😁 I'm a gearing/tire junkie for bikes and vehicles.

maybe it has a speed limit aroun 50 no matter what gearing you use

49 is hauling ass on a bike, that is just crazy fast.

Need a low gear for technical riding or it will spin, too much torque

👍

replace tires with slicks

With ebikes are bigger sprockets less efficient?
