Dirt world?

I was wondering who/if anyone has set up a frame mount for off road?

Any input?

 

I take mine offroad but its horrid if I go too fast

 

i have a few off-road shortcuts i use, but i have to be conservative...still fun tho 8)

 

My botm entry was nicknamed the dirt-kicker right after I built it. But I only had it off road a handfull of times. there's an old overgrown alley behind my block, with a good ditch to cross. we do just fine there. I run a 50 tooth sprocket on it, so it's got some climbing power.

so, Joe..... what are you thinking here? wanna give us a hint?

 

Kings Motor Bikes has a really neat looking bicycle/dirtbike.

Here is a pic

 

Well....I saw your bike and it started the wheels turning......I have also been thinking about the Honda 90 I sold to "finance" my endeavor into motored bikes.

I used it to explore the considerable network of abandoned railroad right of ways around here. I was thinking of making an off road compatable version of one of these bikes. I wanted to make it more suitable for off road than on. I was thinking as light as possible, bulletproof tires, big, semi waterproof airbox, low gear and maybe increased fuel capacity and quiet(er) exhaust.

I haven't had any luck selling the Western Flyer, so I was thinking if I removed the kit from that and started working on an "off roader" I would like suspension, but it's not completely needed as the right of ways are packed gravel for the most part, and I'd rather have less weight.

 

hey, joe-
you said you wanted to make it more suitable for off-road than on...IMHO you should really consider front and rear suspension. i mean if you're going to a lower gear, what's an extra pound or so? think of how much less stress everything will have on it over bumps. riding through town i wish a had some cushion

 

here's some set ups you might like 8)

 

GT used to make a full suspension frame where the triangle was wide open. I think I saw pics of one on this site?
just a thought

 

But think of the chain tension from the engine to the wheel, unless maybe you have a spring loaded tensioner that could keep the chain well tensioned as the suspension moves. Maybe something along the lines of the tensioners for rear derailers, but for the engine chain.

 

good point.

 

rear suspension is really unnecessary, go front susp and just get a susp seat.... I mean, you not moto-xing it are you?

 

if it's what they want, offer suggestions for how to get it to work, I wouldn't go around telling them it's not possible or unnecessary. Are these engines we put on bicycles really "necessary"? no, but it's fun and each bike is different. This guy wants a offroad bike with rear suspension, so let's put our heads together to get it done. :grin:

 

Here Here Good Point Ol'Chap

 

I thought I was offering a solution, maybe it's just my simple nature

I'll wait to be asked next time......

 

I thought the suspension seat was a pretty decent idea.

It wouldn't have the "off road" creds of a full suspension,
but then it also doesn't have the associated liabilities, such as
the need to develop a method of springloading the tensioner.

FWIW, I have been considering adding a suspension seat
to my motorized Huffy beachcruiser, as it's quite the bone
shaker down the city streets!

 

If you happen upon a Cane Creek Thudbuster for cheap, you just might want to buy it.
They come with three sets of elastomers that can be mixed or matched and the pre-load set.
They can really be dialed in.

 

Suspension seats really are amazing, I can't believe I didnt get one sooner. It could replace the rear suspension, it did for me. I got mine for 15 bucks, find one and do it!

I find they develop strange squeaks that won't go away with any kind of lubricant, though.

 

Thudbusters make no noise.
