19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

[johnrobholmes]

I would highly recommend against washers, and offer the nipples we pair with my moped spokes. I keep 12, 13, and 14g nipples with 6mm barrel in stock. Send an email through the site about them and my worker will get you set up, since we don't have them for sale by themselves at this time.

If you got the spokes and nips through us already, we could take your old nipples on trade in credit.

I apreciate all the opinions to my question. I've run 25mph/46kph for going on three years, (maybe 250 miles/460km) so far) on Shcwalbe Bog Apples, with no problems. The do feel a little squishy in corners if I let the pressure bleed off a bit. I'm looking at speeding up a little, and took advantage of the good ebay deal. One pair 19"x1.85" in Red coming my way. It'll be awhile before they're laced up, but gathering bits as I can.

this particular size is rather wide, I have an 80/90x21 on its way at some point thou I am pretty happy with it, about the rest of the build I started a thread http://endless-sphere.com/forums/viewtopic.php?f=3&t=58336

nice! that gonna fit on your bike??

it takes some persuading, its on now some tweaking is order and a couple other knickknacks, like brakes, dropouts, clamping or?

With that wide of a tire, you probably wont be able to use the gears closest to the hub motor, I think your chain alignment will run into the side of the tire. Yah, running a 90/90x21 is wider than an 80/90x21. You should be about 1/4 inch narrower.

 

[2007blueprius]

yeah I forgot to mention that, the 2 largest sprockets are out of commission, I was thinking of making it 3-4 speed, that is all I really use on my 24 speed mtb anyway and with the hub motor, I am thinking of saving the highest gears, maybe I can keep up, or maybe get one of those freewheels with a creeper gear, make a 4 speed 1 creeper and 2-3 high speed

Yah, the 2-3 high speed and the creeper combo is smart for ebikes, that creeper will come in handy if you need to climb something gnarly or run out of battery....

that's what I figured so far, I am not much of a cyclist but on my regular bike I hardly ever use 4 gears, granted most of the time I am just pacing along with the kid, for that 2 will do, so I figured just keep the largest crank a 12 tooth and the next one over and a creeper, in case of a breakdown or such, the large crank and creeper should be about cruiser bike single speed ratio I hope

looks like 34 tooth is about the biggest they get, I thought some of my freewheels had 12 tooth on the small one, will check

that looks so solid. not need to worry about loosing it on a corner with that

I tried the megarange on my initial build. I couldn't get my deraileur to engage the creeper gear because the jockey wheel closest to the cog hit it. To you that you need to make sure that it will work with your deraileur. That was a cheapo walmart Genesis V2900 though and I haven't tried it on any other bike. It was also a 7 speed freewheel.

 

[2007blueprius]

I'm no expert by any means in bycycle parts and mosty of my stuff is cheapos, because I end up cutting them up anyhow and I would feel bad if I paid stupid money for it, and even the higher end stuff I am still not supper excited about I still want to do something different

the jockey wheel closest to the cog hit it, I asume jockey is the derraileur wheel?, cog? is the I dont know, but I get it its a large hop and there may be some difficulties, in my thinking the megarange 34tooth is more so an emergency gear in case of a breakdown or lack of range, I couldnt imagine pedaling home on the highest gear ever, so in real life I hope I wont need it but if it comes to it its there, so maybe I can manually engage it if I must, anyways those are details but thanks for the heads up

that looks so solid. not need to worry about loosing it on a corner with that

I honestly think I overdid it, not so much the 21inch diameter but the with, does not look much like a bike anymore, all in all the tire/tube combo is about an 8 pound penalty and the od is closer to a 29er, you know they make 27 1/2 that would be about it, I like the larger wheels in general for lower rolling resistance higher speed etc, I am not much of an offroader, jumper etc, not too concerned with torque performance and overheating, just want a dependable comuter, and initially I wanted a 29er, should have probably stick with that than I saw this post and went nuts, I hate this hobby,

if I had to do it again I would start by looking for a 21x1.4 rim if they make such a thing and a thinner tire, the 80/90 I ordered may still be too much, maybe a 70/xx in a road tread, andhopefully about 5 lbs, which should be available, this 2 ply is a little over 7 lbs, there is just too much disproportion between the rear tire with and the front one which is a regular 2 inch bike tire, this kindof makes me think of doing something like that on the front, but at that point might as well get a larger hub and more batteries, forget the pedals, see where this is going....

all in all I like the MC wheel I'm just saying if that is all you are going to upgrade on the bike be modest, or it will stick out like a sore thumb

Problem solved, IRC makes a 80/20 road/offroad tire just for you. Its the 2.50x21 GP1. Should com in at 26-26.5" diameter and about 2.75 inches wide or so and around 6 pounds. That's the tire you need for this set up. Someone else got a 19x?? IRC GP1 and it was as light as advertised on DK.

Hey blue, don't despair the fat tire look is the new black. People will think its cool. It's what I was going for when I built my first e-bike. Meet the electric Jeepster:

This bike has a tiny clyte 408 but is still great fun and does just fine. I have gone the opposite direction of most on this thread and started out with MC wheels and now have gone to cycle components for my second, high power, big motor build.

Still evaluating which is best for me. Obiwan

 

[2007blueprius]

I saw those ones, not extremely excited about the patern, and 2.75 inches may still need a little tweaking on a regular frame, the one I am working with was about that stock, no clearence at all unless you shave the tire some, I think my mtb tire is 1.95 I know some are over 2 inch, 2.75 does not sound like much but it may be just wide enough not to clear.

don't get me wrong I am perfectly at home cutting up a steel frame just saying for a straight forward build a little smaller would be better, at the same time I wanted the OD closer to a 29er, so this compromise works for now, on the next one I will certainly try something more modest, thou this is a front MC tire even on the mack of a large 29 looks a liitle overkill, but 21 is the largest available MC rim and to get close to a 29er od you need a tire that big as you noted the IRC would be closer to a 26 in OD and If I were to go for say a fictive 2.25x21 70/80x21 that woul be even smaller just about a 26 inch bycycle wheel, than I could always run 29 up front, should work ok, but for now I got to slap this one together and log some miles

I am not complaining at all, I like it, just saying it is a bit biger than I expected it to be for your average ebiker that may be too much and it strays away from the bicycle I started with, I am getting other ideas and by the time I'll be done with it there wont be much of a bike left.

for someone looking for a straight forward upgrade stay under 2.5 inches, anywhere above that likely you'll be cutting frames or get other ideas, more money out the window, but a cool bike that resembles more a motorcycle, I am not sure what the deal is in Michigan I am sure this allready exceeds the law, well maybe I think 3hp is max, either way no sense drawing too much attention, honestly lately I have been looking at some stealth builds, I kindof like them better, problem with that I am so out of shape on a 250w setup a decent licra will wipe the floor with me :lol:

OBwan, very nice clean home builds. Your second build has some very impressive features like the custom dropouts that blend right into the swingarm and battery cover.

Checked out your build, you got it to fit with some creative frame mods, I like it. Looks mean as shit with that wheel on the rear.

Rick

 

[2007blueprius]

and that was my point, I like it too but this is what you are going to get into, and than you want larger disks and than you might as well build something simmilar up front, initially I just wanted a 29er and I did not want to wait for a 700c wheel from china, figured I'd lace one myself, than figured why not an MC wheel etc, so in retrospect I should have stayed a bit more modest it looks like it dont belong on the bike without further upgrades, a 70/80 x21 in a 1.4 rim would have blended better and not get as complicated, still look mean

CST 2.0x19" tire

I should note that although the tire looks new, the manufacturer's paper label that came on the tire looks aged, as if stored in a warehouse for a while. I thought I read somewhere that some of these tires were older before purchasing them, so I was prepared for it, but I thought I'd mention it in case others are interested in trying this tire.

From a website referenced on an earlier page:
http://www.myronsmopeds.com/category/parts/tires/

19-1 tire 2.00-19
Cheng Shin C109
DI151-023014
(23×2.0) $30

< These 2.00-19 tires are NOS, new old stock. They were made in the 1980′s, but do not have any cracks. They have become smashed and bent from being in a tightly wrapped bundle for many years. The shape becomes normal after mounting and inflating.

Just adding confirming info. How are they holding up?
My rims are at the house waiting. After much searching, and reading this thread multiple times, finding my top choices never seem to be in stock anywhere... I'm going with the Vee Rubber VRM 013 moped tire.

https://www.treatland.tv/vee-rubber-vrm013-moped-tire-19-x-2-25-p/vee-rubber-vrm013-19x2.25.htm Rated 43J = 62mph (99.7kph) and 342lbs (155kg). Sounds like enough. Still spokes to get or lacing to outsource.

thx for that pics. *helpfull

Laced up the Fighter to a MC Rim and tire. Had to decide which size I wanted to go with. From left to right, I had a 19x1.4, two 18x1.4s, and a 17x1.4. I went with the 18x1.4 running the SR241 2.75x18. Came out great. As you guys can see, I employed two different style for truing the rim. The homey the clown swingarm truing method and the advanced homey the clown Vice method with a 2x4 and line drawn on it using the bead as the guide. Doesn't get much lower tech than this. JRH, those 18x1.4 Aluminum moped rims I bought from you had the perfect spoke hole angles punched to line up with a H40xx motor. Perfect spoke angles.

I wonder what these Shinko radial trials tires would be like. 4.29 width, recommended 2.50 rim width. Might be a great 'fat tire'.

http://www.shinkotireusa.com/tire/trail-pro-255

That tire would be way too heavy for any hubmotor short of the 603 Enertrac or the Mamoth Cromotor. I had the 110x18 on a 1.85 wide rim and the thing measured almost 5 inches wide. I ran one of those tire on a 2006 CRF230F which was bored out to 248cc with a bunch of head work and after market exhaust. It dynode at 24.89HP at Sea Level, so figure 21HP at 4000 feet. Anyway this tire bogged my 230 down so much I had to either change gearing or go to a smaller tire. I went with a Maxxis Desert IT 110/100x18 which is still a big tire, but quite a bit smaller than that tire. Can't always go off the posted width data. I have ran Shinko SR241 17x2.75, 18x2.75, and 19x2.75 on ebikes for a while. Every one of these tires is at least 3.2 inches wide or wider, and that's a on a narrow 1.4 wide rim. Shinko lists them as 2.95" wide on their website. As I learned from Zombies build, the 2.75x19 he is running on 2.14" wide rims is over 3.3 inches wide so they do expand with wider rims. You can't always trust the manufacture listed data. I will post some comparison pics of tires that will emphasize my point I have 2 SR241s in stock that are 2.75x17 abd 2.75x18, I also have a three IRC TR1s two 2.75x18s and one 2.75x17. They all fit my respective rims, but the IRCs are close to 1/2 narrower than the totally bad ass shinkos. Anyway I will get some pics posted in a day or two.

Found a review that claimed 11.5 lbs. for weight. Also found reviews that claimed it wasn't good for street duty at any inflation pressure due to the soft sidewalls. I wonder if they'd do better on lighter machines? One review said it was a great cold weather tire, but not in summer. Maybe it has a niche as a fat tire for slow winter driving?
