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

I could send it all no prob but I'd struggle with the correct spokes .. seems like a bit of a mine field..
Was thinking of this rim:

But would it need nipple washers etc.. I'm just not wheel build savi Argh! :oops:
 
I have just bought 2 of these

and 72 of these

Guys, anyone recommend somebody to lace up a cro to a 19" Moto rim in the UK ? Don't really want to take this on myself?

What I used to do before I dived in with a truing stand etc, was to lace up a wheel (the time consuming bit) then take it to a bike/motorbike shop and get them to tension it up. Ive heard that sometimes for legal risk reasons, in the UK, they wont build a wheel from scratch but if you take in a built up wheel and get them to tweak it, then the emphasis is off them. Just copy the spoke pattern of another rim/wheel.

Hey thanks for that.. I really could do with it all done by a pro tho. Had a recommendation to try a Guy called Bob at http://www.teamhybrid.co.uk/
Sent an email and he defo seems to know his stuff! just have to make my mind up.. having doubts over the weight of a cro..?

A cromotor into that nice looking rim is prob the hardest build going for your first shot at building, so yes maybe get a pro to do it. Those guys have been around for years and will do a good job I'm sure. Maybe try a front wheel (if you need one?) loads more forgiving!

I think you should give it a shot. My first time was lacing a cromotor into a 19" prowheel. It's not to bad once you grok the pattern. If you need some visuals there are all sorts of youtube vids.

Heres my first attempt. I've put a lot of miles on it already.

10kw carbon.jpg

Heres my attempt at the lightest 10kw carbon build, along way off finished. Going to be road registered in the UK as a motorbike. All be it a motorbike that only goes 10 miles before charge, waiting for battery technology to get me further! 2.75 241's fit well in modified rear triangle. Lets see if it holds up?

That's sweet, but I got to ask, since the goal of your machine is clearly light weight, why not run MTB rims and a MAC10 geared hub, that would be perfect for what you got going on here. I bet you would have an under 55 pound ebike. Really great looking machine though, do you have a build thread showing the CF mods in detail? Would like to subscribe.
 
10kw through carbon?

I'd be scared to ride it unelectrified with the weight of those wheels....

I wish you luck and make sure you wear a full face helmet and full leather jacket and pants - because if that carbon fails suddenly at the speeds which 10kw can produce it will not be a gradually noticable problem but a sudden catastrophic failure.

Purely because I had this motor and other parts kicking around from my old build; I was going to take it apart and mod it, however am open to suggestions like the Mac10, sounds good:)
No build thread yet but will start one soon. I put this bike together today as I wanted to test it out for angles/stress points before dismantling it and doing it properly. Very much still prototyping. What benefit would MTB rims be over BMX rims? One must is that I use road legal motorcycle tyres and prefer a smaller wheel. I'm used to 17inch supermoto bikes, so trying for that sort of ride :)

That's why I'm doing it! When I say carbon, its ultra modified, I.e the rear triangle has been opened out and filled with and Alumilite/carbon mix. Its as tough as hell from what I can gather. I can jump up and down on it with hardly any flex. This does however start to defeat any weight saving over aluminium/cromoly etc, however its really quite a nice material to work with for modding purposes.
Time will tell and yes I agree, a full face helmet for test day!
 
did you have a build blog?
to build a CFK Frame you must have alot of skills...on my RC Hobby time, i build some Carbon Fenders for a bike....it was a PITA (!)

i would like to see what kind of negative forms you had and how you ......forget, i want to see EVERYTHING :mrgreen:

I'm not claiming to have built this from scratch!!! this is a blank frame from the same Chinese factory where they resticker frames under many guises i.e Giant, Specialised etc.
I'll start up a thread soon, however am no expert at carbon mods but wanted to see what the possibilities are.

It was a bit painful to take my dremel to a new carbon frame but actually quite interesting to find out which parts are solid, which aren't and the general construction of the frame.

I've just snapped one of the original crappy pivot bolts so will be replacing them all, prob with titanium ones and new bearings etc.

I'm figuring that if i can route all the cables and wires needed through the hollow parts of the frame and then fill it with something like the Alumilite that ive been using, then end product should be pretty stiff and tough. The batteries are a snug fit encased in aluminium, so the down tube is taken care of. The rear triangle will have cables running through and will be solid. What can go wrong ;)

Anyhow i'll start a thread and post it on here so as not to take this one over.....
 
I'm getting a wheel built by roadrash to mount on a dnm usd-8 dual crown fork with 20mm thru axle. The Shinko 241 2.75x19 (what I want to use) is actually 3 inches when inflated. Does anyone know if it will fit in between the stanchions. If no one knows I should be getting the fork on Friday and will post the answer here.
