How Much Better is a $10,000, 12kW SurRon Against Stock?! 

Awesome video as usual! That Built Ron is epic. Can you guys possibly do a weigh in of the two?

Love the honesty and review

I love the build out guys, almost like two different bikes. I've mulled over doing this to my surry but just not sure. I sort of like the low key MTB look of the stock version, you can get away with it in places where if you had larger, fatter tires and more aggressive power, you might stick out more and could "get into trouble". I have a 160cc, custom build light weight dirt bike that sort of fills the need of that modded surron. 90+kph, full CR85 suspension, can ride all day on one tank and it has a clutch and four gears so it actually requires some skill to ride :P

Mine will be here.this week. I have a bac2000 already and ERT NXT display and a egg rider v2 I already run two ASI bac855's one a bbshd ebike so I'm a bit familiar with it and the nxt

one reason I chose the 16" rear is for racing purposes. I race pitbike races and the maddog class restricts you to 19/16 max wheel sizes. Offroad 21/18 is always going to be the best for roll over and ground clearance though. If you want a bike that can still do good on trails(better traction) and race in smaller bike classes where the chassis and wheels match, the 19/16 is great option and you only need to upgrade one one wheel. Also there are getting to be some great tire choices for the 16" as there are a few gummies where just a year or so it was only 18" options so you can keep weight down and crazy good traction. Theres alot of factors in wheel sizes for sure

Would like to see a fork set up video for the fast ace forks.. I've seen a few different vids on the subject but none on the fast ace frontend

I would so love to see a comparison between your $10k sur ron and the CAB Motorworks Recon. Thanks for the great videos.

What tires would you suggest for an upgrade with the stock wheels…for a mix of trail riding and on road riding

What kind of seat is that on the 10k bike?? More or less the set up i want.. i like the luna float seat but would like a lil longer..

Did you make the orange one taller just by bigger tyres? Stock sur ron look a little small for my lanky body lol

Hey, do you guys ship your products to Europe? (more specifically France)

I would agree about upgrading the sprocket to a bigger one on the stock one but I think 54-58 is the sweet spot for stock. With the testing I’ve done, the 64t is nice but not much more benefit for the loss in top speed the torque seems very similar between the 54-64t on stock

I wish you had compared the top speeds. I love my Sur Ron for trail riding. But I also want to use it to run to the grocery. And the road I take has a 50 mph speed limit. And it's uphill one way. Need enough power to climb uphill and hold 50 mph.

not the slippers lmao

Thank you for the video, I can’t find on your part list the reference of the 19’´ rear wheel… Can you tell us about it please? Thank you

I hope I didn’t offend you guys on the last vid, I just think these vids are better. I respect the honesty I really do we all do but I also see it’s beginners and experience. And your comparison vids say the same thing but so much more! I love when y’all do these vids. All love!

Respectfully, there's more to consider when evaluating rear wheel size than just whether it improves ground clearance. 16" still wins for best all around improvement and opening up more tire selection.

What are the top speeds of both?

any idea on a time frame till the next batch of controllers??????????????????????

Sweet !

When will the BAC4000 be back in stock? Your videos convinced me to get one but it's been out of stock haha

ok someone needs to do a test I was raised in the 80s so back then all we had was peddle and 0 LED as far as headlights goes. but we did have headlights with generator and make 12 volts or 6 volts cant remember but that would be cool if some way some how you can use that to charge the Bike or some other form of device

Do you have video explaining how battery is constructed? Fire protection? Overtemerature? Mechanical protection? Resource? Cycles count?

I want to ask if that kind of bike is already available here in our country Philippines thank u

You should a breakdown of every part on the 10k bike

What would a happy medume be between the stuck & your bike? A sprocket & controller equipped bike?

As humans we have a tendency to want to modify everything yet with this bike many are missing the point - The X comes stock as a good all rounder and with a change of sprocket, a suspension tune and sorted tyre pressure it gets much better. I find it thrives on tight single track in that 20 - 40kph speed range as I can stand on the pegs and lift the front wheel whenever I need to. Yep, you can modify anything yet blowing dirtbike money on one of these things is probably going to see it slowly fall apart around the extra power and forces placed on it.

hi. what is your height and isnt it short for you?

If I plan on purchasing one of your BAC4000 and bypass kit's, would you recommend getting a SurRon or a Segway 260x? Thanks.

Does the 21in front tire fit in the fox 27.5 fork or do you have to run the 29er fork?

I don’t want the nice one, i want the mean one!

What size rims on coles bikes

my mans wearing dirt bike pants with slides. lolol

Hi guys. Tell me please. What size of tires do you use on the front and rear wheels? and brand

Am i hearing the rear tire of the built one catching ? If so what is it catching on ? asking for scientific purposes

Curious what would be the best FIRST upgrades to do on a stock SurRon in your guys opinion???.. I might get one and for me I’m all about range, so I was think a Chi 60v 60ah battery, then maybe next the bac4000, THEN stuff like fox 40 forks, etc. BUT WOULD LOVE FEEDBACK! Also, I’m not mainly an off-road rider, this would be a mixed bag and nothing crazy. Thank you

So 10k with bro deals and hook ups? what would retail be on it? Great vid btw, like you said for what its built for, a stealth urban assault mobil, probably best thing out currently.

How much did the stock cost

Ok this probably a lame question lol but does any of this matter to a guy who's just gonna use it as a eco daily commuter? Would a stock bike with a upgraded battery give good results?

Which camera do you use for filming?

I know very little about bikes in general, but I am interested in getting one. Question: Why would one acquire a 10K SurRon over a 13K Stark Varg. I guess you save 3K with the SurRon and it's marginally easier to get the SurRon in the back of a pick-up. However, I would guess that even though that Stark Varg is 30% more expensive, I would guess the that Stark performs 200 - 300 % better in many or most categories.

if you are plan on going 72v order that shit a month in advance. they told me the "lead time" is 5-7 weeks which i wish i knew ahead of time

10000 $for 12 kw is not much for 10 k you can have a really powerful ICE bike. Sur ron is great but would be so much greater if for same price around 6k we would have a 72v capable version

The gladiator battery seems game changer for the Sur Ron

Why haven't you tried XL kit to get new level of performance yet?

What helmets are you using?

If you're willing to drop 10K, you should wait for a Sur Ron Storm Bee. If the wait is an issue, perhaps a KTM Freeride instead. I love my Sur Ron X, but one of it's best features is it's low price. Investing up to 10k is foolish when there are better bikes for the money.

I wonder how well the stock belt holds up to 12kW of power over time?

Anyone know a place or specs for the head set bearings to fit with upgraded forks???

for that price id just get street legal storm bee

I’m in Britain and would like a customised one next year. Any thoughts?

I thought one of you guys had the fox float x2 air shock in the rear

If I upgrade the wheels can I still have the kickstand?

Can you use the rear brake while on throttle to keep the front down? Kind of like a clutch on a dirt bike.

Are you using the bac4000 controller ?

It looks like the rider plays a huge part in the difference.

How much for this bike all set up the way you have it

Nice vid =) Got myself a 2021 surron some weeks ago, loving it! But one thing i hate is the throttle... i have to turn it so much to get full power. Is there anythin to do about it?

I am on fence about buying a sur ron and modding it like this or buying a zero fx/fxs. Can you compare this bike to one of those?

You should link all the upgrades

Nice to see other one trys 100 90 19 in the rear 🤪 ...no cutting ?

Definitely cool modifications, but at that price, it makes more sense to get a Zero FX and be street legal.

Those wheels tho . . . dang ! Are you guestimating the upgrade is 10k over stock price or including stk.

Fuck yeahhhh

damn, 10k is a new electric ktm freeride e-xc.

AT 10K though, how does it compare to a KTM E-XC, or even a ICE 300XC Then you have real suspension, and real brakes

How much does each weigh?

Damn idk my stock one hit harder. Never really struggled uphill

What’s the runtime on these things?

I spent two years programming BAC4000 and its super buggy by nature. I am not a fan of this controller. For 10k you really should be looking at a Storm bee or better yet a Zero

If i have money, i would buy Electric Motion Escape R rather than 10k sur ron mods

Parts list on the 10k?

Can a big guy ride these? 260lbs +?

My 15 year old daughter has a SurRon with a KANIWABA pedal kit on it ro make «legal» Fantastic toy, but with a 10 grand upgrade it is more than a new Stärk Varg… -And that is another galaxy…

Does anyone know someone that has replaced the the motorcycle with a gasoline engine after the parts and labor are too much?

what about upgrading the motor?

How would the modified Sur Ron compare to the stock $10,000 Stealth B52 bomber. Be fun to know

Why can’t I sub?!?!

no no no a 16 in rear tire has a massive variety of tires and you can fit a moto style 16 rear that has less centrifugal force allowing for better stunting better e braking better power to ground you can use a smaller sprocket and still get gains. the lower the power you bike has the smaller the rear provides gains a 21 on a mountain bike has insane limits to tire size and yes it handles better speed over rough terrain but then you basically must improve forks. a 21 only really benefits taller riders. a 16 or 18 is best front tire based on science. preference or opinion may vary but science takes a lot of factors in to account. without the battery and controller enhancement larger wheels will cut power drastically the only benefit larger tires truly grant is top speed on flat or decline

Wish you guys would talk about the durability improvements gained by your modifications. I used to have a Sur-Ron, but sold because I felt the stock bike was not up to the punishment I would subject it to, and so chose to sell the bike while it was still in good condition. To me, the extra money to improve the suspension, power, etc. isn't worth it if the bike isn't capable of holding up to the type of riding you're doing. I was hoping the Sur-Ron could be ridden like a dirtbike, but it's not (at least not in stock form) capable of holding up to the type of jumping and other hard riding that dirtbikes are made for. Even with better suspension, certain components like the headset bearings, the rear shock linkage, and as you mention, the skid plate, are simply not rugged enough to handle more aggressive riding. So for me, I wish you would have talked about the weaker components of the Sur-Ron, and anything you've done to improve those components, and whether those upgrades/modifications have been worth the money, because that would be the only way I would even consider another Sur-Ron. Even the Storm Bee looks like it isn't built to handle the punishment of dirt bike riding (I'd buy the KTM Freeride E over the Storm if that was my only option). Too bad the Alta is no longer available, that was a great E-bike. Still waiting (and hoping) for something like it from another manufacturer (KTM, Yamaha, Honda all seem to have concept bikes in the works), but for now I'm enjoying the content on you channel and others like it. Keep the mods coming ... who knows, maybe one day your mod bikes will be exactly what I'm looking for.

The Surron x is really a mountain bike with a mid-drive motor and battery which anybody or u can make on ur bike for alot cheaper

Next time have equally skilled (and weight/height) riders when doing a comparison. A skilled rider with finesse can get more out of any machine.

6:15 looked like the SuRon was in slow/eco mode, that was sad looking.

10k ebike or a nice car 🤔 I'll go with the nice car and a peddle bike 🤣

You don’t keep enough product in stock for us to buy anything

For that money, get an awesome YZ125

10k surron but got 30$ bars lol

buy a storm bee....

Why do huge people want to ride a surron? If you’re too big get something bigger these bikes work best for small people

I don't understand the point of this comparison... a $10,000 vs a $3,500 bike ?

you 20000 usd alibaba 😆😆😆😆😆

at this point you can just get New 450CC Husqvarna

Ruining mtb trails...blatantly.

Obviously you are not a cross biker - you don’t get a lot Of thing that we do (12 years riding motocross!!!!) so do appreciate you thoughts but - NO!!!!

alibaba 1000 usd 🪗✌️✌️✌️✌️
