SurRon 19” stock wheels vs upgraded 16”/19” vs 18”/21” wheels and tires acceleration test/shootout. 

Appreciate it!

Interesting, I'll have to try to find one of those, our distributor does not carry that brand.

Glad you like them!

Thanks for watching!

hahaha, sorta kinda??? It's just a Poison Spider sticker from the bike shop down in Moab :) love it!

Thanks for the feedback, the battery was on charger between each set of tires, battery level never dropped below 92% during all of this testing. Also our fastest runs were rarely the first run so 100% is not required for max power. The 18/21 is significantly heavier and also has a much larger diameter putting it at a gearing disadvantage. Physics... Honestly we expected the 18/21 to be even slower than this, 5% acceleration loss is pretty good in consideration of all of these factors. You can feel the power loss on the 18/21, it's noticeable to anybody who gets on the bike. This is the reason everyone runs 60t and 64t sprockets with this setup, it's needed to return the power. :)

Max capacity is the same all the way down to 60% then it starts to drop in performance by a little bit, mainly top speed.

You asked we deliver! I don’t have weights for a naked OEM wheel yet...some day I’ll add that. chargedcycleworks.com/pages/sur-ron-tire-upgrade-specs-and-weights

@@ChargedCycleWorks If you could get the weights of all the different 16” wheels that would be superb.

not an easy question to answer. Essentially 16/19 if you want to keep the fun,nimble,playful nature of the bike and certainly if you don't want to invest in battery/controller upgrades to overcome added weight which is just about a requirement for 18/21 with all the added weight. All of us ran 16/19 at TKO for a variety of reasons but the #1 reason we did it is tire selection, it's not possible to run a gummy tire with foam inserts in 18" on a surron, they won't fit. However in 16/19 we have an incredible tire selection with many gummy tires available and even foam mousse inserts to guarantee no flat tires in extreme enduro which is crucial for that type of event. HOWEVER the bikes that finished in front of us were Electric Motion's with 18/21's and gummy trials tires which was an advantage through the rock gardens. These bikes also have a longer wheelbase which was an advantage on the many hillclimbs. In a nutshell: 16/19 for most people, 18/21 for those seeking a larger bike and willing to invest in power upgrades.

@@ChargedCycleWorks Understandable with that being a hard question to answer, but I really appreciate the thorough response you have given me, thank you! I have on order a ko motor, controller & 72v chi battery. So lack of power won't be my issue. I have challenged this question to many popular sur ron off road youtubers many are saying 19/16 while others are saying the bike is limited by its smaller tires and think 21/18 is the only correct answer. I wanna buy a nice wheelset so I am trying to get my choice right the first time lol. Again, thank you! :)

Will a 19 fit on a Segway x160? Would I be able to leave the 17 on the rear? What’s the purpose of switching to a 16? Thanks!

it would not be a good combo, you would be shifting far too much weight and balance onto the rear end making for a poor handling and steering chassis. When it comes to tire combos simply look at the motorcycle industry where they've perfected it over the last 100 years. It's no different on surron. A 90/100-18 like the super light weight K990 is the perfect match to a 21" on the surron. And a great 70/100-19 MX tire up front feels amazing with a 16" MX rear tire which is the setup used on Motocross racing bikes with the same chassis dimensions as the Surron, bikes like KX85 and KTM105.

Yes, our wheels come dished for the tire you purchase. Our hubs are manufactured to offset away from the chain for no or less dishing required. Our wheelsets and hubs are made for 3.5-4" wide MX tires.

Nm so much, so fucking much to learn n know about all the sprockets n chains n all, I'm done

Can't speak for Woody's since we build and sell our own, but almost all your questions are answered in the descriptions on our wheel pages.

in the thumbnail it was an older 3" MTB bar we carried 2 years ago. We have since replaced them with Motocross ProTaper Gold bars here: chargedcycleworks.com/products/protaper-mx-gold-handlebars-28-6?_pos=1&_psq=protaper&_ss=e&_v=1.0

The gold handlebars? chargedcycleworks.com/products/3-riser-bars

yes you can, they are interchangeable, the only thing to be careful of is the X160 might have a smaller fork and tire sizes might be limited to 70/100-19" inside that fork. Not a big deal as there are amazing tires available in this size.

No, the hubs are completely different sizing/spacing front and rear.

Hey Zack, a bit confused by this comment, you would keep your stock front 19" wheel up front and upgrade the tire on the rim to a much better mx 19" tire and then install the new 16" rear wheel tire for a 16/19 combo.

18" rear is better for off-road riding, less pinch flats and better traction with lower PSI. 100/90-19 is a motocross tire meant for tracks. You can't really run a 70/100-19 with a 21" up front, will be off-balance with gobs of traction and weight up front and not a lot out back.

@ChargedCycleWorks iv changed it to 19s f&r. Idk much about side wall sizes so far I'm thinking these tyres F80/100, R90/100 should I have different walls?

16" rear provides a superior tire selection from the motocross world with tires of all terrain and rubber compound options. The traction and handling is superior in every way to the 19" rear tires which are all tires made for the front of a motorcycle not the rear.

16” yes, 18” not unless you do some hack job to your kickstand to force it to fit.

I've got a 18x2.15 Excel wheel offset 1/8" from Woody's Wheel Works and much to my surprise I didn't have to remove the kickstand. I'm running the Dunlop K990 90/100-18.

Thanks for the feedback! Did you put a longer chain on and move the wheel all the way back on the chain adjusters? That might just have enough room on the 90/100-18, but hadn't tried doing that yet. We also just got a K990 and will be mounting that up soon to see how it clears vs the MX33.

@@ryanboone7389 so do you think i could run a 19x1.40 or 19x1.85 from woodyswheelworks in the back with the offset and run a 100/90-19 or 90/100-19 in the back without having to remove the kickstand?

@@Ace01010 We also offer the same exact wheels and have 18" black Tusk, gold or blue Excel's, and 90/100-18 tires/tubes/rim strips currently in stock for faster delivery. chargedcycleworks.com/collections/wheels/products/18-charged-custom-rear-wheel-for-sur-ron?variant=39382093201603

Actually, based on our testing our fastest acceleration runs were rarely the first run, it was often the 2nd or 3rd run that was fastest. This confirms that our testing was fairly done and that a few runs on each tire did not affect battery discharge rates. In the video we said we would not test below 80%, but we never dropped below 92% during these runs and we charged while we were swapping tires/wheels. We feel VERY confident in these numbers based on our real world test data.

Take the second left after you've passed the old oak tree

This test was specifically designed to highlight the size and weight different in acceleration in a controlled environment (perfect traction). Keep an eye out for our upcoming lap times shootout where we test various wheels sizes on different dirt tires on a familiar dirt track.

hmmmm, you might want to contact Excel and tell them that all of their marketing is wrong and that they should not call their rims, ah rims....

@@ChargedCycleWorks He's right, rim is the outside of the "wheel". Hence why it's wheel and tires... Never say I need some new rims in a bicycle store because they will laugh 🤣🤣

​@@bslothed3211no they won't... we call them rims.
