I think I read in some thread that this is how all the Russian guys do it. I think Allex is the one that posted that after his ride with Andrey in Russia.

There is a lot of pressure on me here if you guys are going to change out your already bought tire.
I don't know what to say. I know it worked for me and my riding style. The more I think about it is safe to say that there is no reason to use a 19x2.75 shinko tire on the rear.
The 19x2.75 tread seems much harder than the 17x3.00, it's much smaller with smaller knobs, can't run as low air pressure. There is no 19x3.00 option as gas motored bikes would not use such a large tire up front and I believe the 19x2.75 was made as a front tire.
So take the 19x2.75 and junk it. The 19x2.75 was amazing compared to any bicycle tire, but nothing compared to the 3.00 shinkos. The 3.00 are probably designed as rear tires for traction.
The other options are the 18x3.00 and 17x3.00. I would say that if you're going to use the bike for mostly street use than the 18x3.00 will work well and you get most of the benefits of the 17x3.00 and it won't look as small. If you really want that extra climbing ability and extra acceleration, then get the 17x3.00.

We're using Shinko 19x2.75 front/back, and they seem more than adequate. I'm sure the 17x3.00 offer great torque, but I'm struggling to see how they would offer more traction than a 19x2.75? We are using a spread of 19x1.4 for the rim which could explain it, i.e it's more narrow instead of fatter like when using a 19x1.6"

You bet there is!
We are many thousands of miles away from wearing out our new rubber, not to mention the custom mx wheels that we either built ourselves or paid others to build for us.
I for one got discouraged with 19" after I went shopping for 19 x 2.50 rubber and found such a limited tire selection after measuring my frame and realizing that I didn't have the clearance for 2.75's.
Before i read your recent comments, i had already decided that on my next build i will use 18" simply for the greater tire choices. Your comments about better performance are just icing on the cake.
Thanks for sharing your experiences.

I think the look of 19 and 19 better. Might be s good enough reason for some.
That being said, I am trying the 17 and 19 on 2 bikes.

We originally wanted 26x3 back and 26x2.5 front, but there was very limited tyre selection though we liked the look of symmetry, and loved Snells build. Then we thought 24inch bicycle tyres with 3" back and 2.5" front, but the Duros and Halos are hard to come by and cost as much as the Shinkos. Which is why we decided to just stick to the 19" Shinkos front and back, knowing they're easier to source, cheap and will outdo a bicycle tyre.

I'm looking forward to seeing what the 140 frame looks like with 17,s front and back.

Here is what a SR241 3.00-17 on the rear and a Sr241 2.75-19 on the front looks like. Its been so long, I forgot the builders ES name, but if I recall correctly, he went this route because of how much I like the 3.00-17SR241 on the Bomber when I had it. Funny thing is I don't know if he finished building the bike or what. I guess I need to go through the Phasor thread, get the ES Name, and PM him as I am curious as hell how the final product turned out. But as you can tell, the 17 on the rear and 19 on the front look great together.
Rod, 17s on the front and rear of the Raptor, run the M62 2.75-17 front and 3.00-17 rear, and you got a Super Motard that can be pedaled
That will be really sweet.Attachments

marcn, The 17x3.00 offers a lot better traction because the knobs are much longer. The tire compound seems to feel much softer. You can run lower PSI them. Take a look at Rix picture above of the 17x2.75 front and 17x3.00 rear, you can see the rear tire is much fatter.
Running low Air pressure seem to make a huge difference. The rear doesn't bounce off things nearly as much as before. This was a big problem of mine and I heard it was because of the heavy rear wheel and you could never get the rebound setting low enough unless you had a custom shock. A lot of things I would hit the rear would bounce up uncontrollably. This doesn't happen with the 3.00 tire with 15PSI, at least not nearly as much.
If anyone is not going to off-road there bike much and doesn't want to lose range with resistance issues than you could try the 2.75" tires. Even then, I would say just add a few more batteries as the ride will still be much more softer when hitting anything on the street with the fatter tire.
Honestly, because the 18x3.00 is almost the same size as the 19x2.75, you would be much better off having used the 18x3.00.
Rix, I assumed you never recommended the 18x3.00 option because you couldn't find the tire? Did you also ever receive your 18x3.00 in the mail, how does it compare tot he 18x2.75?

I got the 3.00-18 SR241 now. Its about 2/3" smaller diameter than the 2.75-19. (Both uniflated and not mounted on a rim). I mounted the 3.00-18 and had to take it off, the chain line between the crank and free wheel hits the side knobs. Even though the 2.75-18 SR241 clears, its not by much. But my next Mod on the Fighter which will most likely be a 54xx, which will push the chain line away from the tire. I could get a 1/2 free wheel spacer and achieve this as well. I will have to get some aluminum washer/spacers to align the chain ring on the crank so its perfect.

Rix, when comparing the 3.00x18 to the 2.75x18, is the 3.00" tire much larger with longer knobs? Does the compound feel softer?
Would you recommend the 3.00x18" over the 2.75x19" if you can fit both tires?
That's too bad you can't fit the larger tire.
I'm off now to see if I can get the raptor into Manhattan with public transportation.

Offroader, its hard to say if the 3.00-18 is better than the 2.75-19 being that I really haven't had any time riding the 18 yet, yah, when I mounted it and road it around the block with the chain off, it didn't feel any different than the 2.75-18. I cant tell much from around the block pavement riding. The knobs feel the same as the 3.00-17, which to me feel not so much softer, but spongier than the 2.75-19. By spongier, I mean more flexible. Been a long time since I ran the 2.75-19 on the rear, but what I remember was the 2.75-19 on the rear wasn't any difference than the 24x3.00 Razorback, and when I went from the 2.75-19 to the 3.00-17 SR241, there was a very noticeable increase in acceleration. Size wise, the 2.75-18 is 24.2 inches vs the 3.00-17 which is listed at 23.7 but my tape shows 23.5. Performance wise, cant feel much, if any difference. For the 18x1.4 MC rim, I am deduced to think the 2.75-18 @ 24.2 inches will feel closer to the 3.00-17 acceleration wise and the 3.00-18 at 24.7 inches will feel closer than the 2.75-19 acceleration wise. Obviously what ever diameter size some one goes with, the 3.00 wide size will have more traction in loose stuff than the 2.75 wide. I know this doesn't answer your question completely, but for me to accurately rate a tire, I need to put 200 miles on it in various terrain to give better feed back, cant say that about the SR241 3.00-18.

Hey not bad! I am pleasantly surprised.

Ha! Hilarious. Pics or it didn't happen! Also, don't let someone steal the bike while you are taking pictures of it! Even pedaling with no key, it might be hard to catch them!

Now we know the look that is going to get electric bicycles banned from unregistered use nationwide. Great.
If these jackasses would just get moped plates, we wouldn't soon be facing 500W e-bicycles having to be registered and insured. But no, can't do that-- even though they are currently clearly defined as mopeds or even motorcycles under the law.
I'm still waiting for an even more audacious jackass to put pedals on a Tesla Roadster. Legally, that's the same as y'all are doing.

Hmm... I'm going to out on a limb and and say that's probably not the best way to win folks to your cause....
Chalo, didn't think you even looked in these threads.
E-bikes of any watts are actually banned completely in New York State so I can't make anything worse here. What actually got NYS to ban them? Those low wattage bikes all the delivery guys use in Manhattan, the 250-500 watt kits.
But yeah, if these bikes ever do go mainstream I see them cracking down on them. Buy and use them while you can and take advantage of the fact that nobody has ever seen one and doesn't know how to classify it. I bet cops don't bother with them because they have no idea about them or the legality.
I had a good laugh at chalo's post because we are really pushing the ebikes to a whole new level with these things we are building here. I'm also driving around a very flashy bike here that looks like a dirt bike and has colors that seem to attract everybody's attention. The huge dual crown fork with those gold stanchions, white bike with red lettering.

DK, have you ordered tyres, and did you get any 17,s and if so have you got any spare.

In seriousness to Chalo's post, I think the real issue is that ebikes are in a no man's land right now (as Offroader alluded to). It is too difficult to register (if possible at all) and the ebikes rules seem to be getting tighter. It doesn't leave a lot of room for the big power bikes.
That being said, I don't think we should stop Development of something because the law hasn't figured out how to regulate it. We'd be just slowly regulating our way out of dark ages if everyone took that approach.

Chalo, you know $h!t. As Offroad said they are illegal in new york, but the way bike messengers ride there, the cops are going to enforce the bike messenger running through red lights and causing traffic to stop before they enforce an ebike following traffic laws. I am not talking out my ass, I have 17 years behind the badge and currently am a Patrol Sergeant. I see more gasser Spooky Tooth conversion kits on bikes then I can count, and we don't even look at those if they aren't failing to yield for traffic control devices, speeding through school zones, blasting through the parks, in other words, endangering the public. A while back, I clocked a lycra wearing Lance Armstrong wannabe hitting 50+ MPH down Mt Rose Highway. I could give a crap. If Offroader rides smart in New York, he will have no problems. The only way our high powered ebikes will be banned is if the public demands it from City Mayors, County Commisioners, elected Sheriffs, Chief of Police, or appointed mayors. And that wont happen if we ride smart in public places pedaling our machines, regardless of whether we are running 50 watts, for 15000 watts on any ebike that can be pedaled.
