Stupid
kind of reminds me of those ugly honda dh bikes
A bike that you don't pedal... kind of defeats the general purpose doesn't it?
lthumbsdown:
Didn't some kid on this board build one of those for a school project?
I don't know if anyone has read the write up but I suggest that you do.
It is the most pathetic sales pitch for the junk on wheels. It is absolutely pathetic.

Like.... really? The fvck man. The fvck.
Always with the 5050s on those bikes, like they're determined to **** up the remains of the bicycle under the ugly.
This is a mispost. You should have typed the idea in a blank document, and then dragged it to the trash.
I wanted an FX bike real bad, but not for the price. Just build your own and use a small turbo diesel. That would be awesome.
small turbo diesel?? what size engine are you talkin about??
Your gay but I still claim you as a friend..........
You'd be chased off the DH trails, you'd be laughed off the moto track.
Where exactly does this bike fit in?

So, Rufus...what are you REALLY trying to say??? Don't hold back, man! :biggrin:
Like a 2.5hp Yanmar with a mini turbo on it. I can't find a picture, but I'll keep looking. I had one spec'd for a motorcycle project a while back.
dumpster?
Oh, cool. Crummy bicycle and crummy motorcycle in one convenient package.
Looks like a souped up moped to me.
a small Volvo turbo would work on that i suppose. ive seen them on lawnmowers before, so i dont see it wouldnt work for a motorbike
which are like fat chicks.....theyre fun to ride until someone sees you riding one
while not arguing for this particular instance, i think the concept of a machine in between motox and dh 2-wheelers has promise. electric power might be the answer to trail access issues for the motox crowd, and why not make it lighter once the design constraints of the gas engine are removed?
but how much would battery cells and motor weigh in order to get a decent range? especially compared to a gas or a small diesel like JimmyDean recommended.
FOUND IT!
One of these on a very small diesel engine (one used for portable generators) could put out a good amount of torque.

thats the engine?? wheres the piston??
you found that on ebay right?

That's the turbo, with blow off valve. I was talking about putting that on a single cylinder Yanmar or other diesel. They make small 2-3hp engines for one hand carry generators.
<edit> Like this, sort of.

i was gonna say....that didnt look like no engine ive ever seen. im a moron
thats a pretty nice sized turbo for a small 1-cylinder.
turbo diesels are my fav
If I'm ever on a trail and some dude on a motorized mtn bike is riding my ass I swear I'm gonna freaking lose it.
better watch out then........one of those would be right up my alley.......no more pushing back to the top, just braaaaaaaap right back up & back down
BS and I had a great conversation a while bake about full blown dirt motos running diesel motors. There are a bunch of cruiser/chopper diesel setups, but only a handful of dirtbikes. The main problem is the coupled engine/trans. One option would be to convert the gas dirtbike engine to be a diesel engine, but that it a ton of work. The other option is a separate trans, like a Harley style, but that's heavy.
yeah, converting the gas into diesel isnt feasible really.
hell if theyre putting rotary engines in bikes now, why not diesels? they have their big advantages over gas

I have seen diesel based choppers that get 100mpg. Not the fastest things out there, but sure beat a scooter
they must sound sick w/ their large exhaust pipes.I have seen diesel based choppers that get 100mpg. Not the fastest things out there, but sure beat a scooter
100mpg is a little above what bikes are getting nowadays isnt it?
I am pretty sure I wont be on the same trail you are.....
My R1 gets about 38mpg. But it's the price you pay for 167bhp vs. a 3-5hp diesel. Kind of like comparing a Prius to a Vette.
