Bring out the mouseketeers, and you can start your own Mickey Mouse club.
You gotta make a few more posts, that's all.

Obviously the operators are not familiar with vBulletin, all they need to do is flag posts with links, set them up to be moderated and a moderator either approves or disapproves the link.

I can make 20 posts of rhetoric then put in my link? So that resolves the spamming problem? Not in my world.

o.O

or just a 3 post minimum - which is easy enough. You just managed to do it so all's well.

It stops a LOT of spam thanks and I think the mods here would rather play with their bikes than babysit every link.

Charged can you get someone to follow you and look for the rear wheel to shift left or right? A swingarm setup like that is prone to wheel walk. The original shaft drive motorcycles use to do it. The torque would twist the rear wheel sideways. That maybe the "flex" your feeling. The pivot and the swingarm itself would need to be very tight and strong to stop it. A normal rear triangle the seat stays stop it. Also the pull of the motor drive chain could be pulling the whole swingarm to the left. I've wanted to build a rear suspension bike similar to those but coming up with a swingarm pivot that is stiff enough but doesn't weigh a ton has excaped me so far.

That is the problem that I am having with this build is the
swingarm. You can spread it apart by hand or push it in by
hand very easily. I think it would have to be replaced with
a stiffer tube type than the box type that is on it now.
It makes a very good peddle bicycle but not a motorized
bicycle. I think the way it is now that a front wheel friction
drive would work on it. But that was not my plans for it.

Well, unfortunate as it is that it didn't work out there's still potential - and I just wanted to thank you again for being our guinea pig. While I'm sure I woulda gone nuts with a welder and mods and come up with something eventually, you saved me some cash and frustration.

I'm still half considering it actually... keep us informed on what you end up doing with it, and thanks again Charged!

It rained all day yesterday and that gave me some free time to mess
around with the soft ride bicycle. I installed a front springer a while back
and that gave me my steering problem with the bike. That was my first
rush attempt or noob. I put the original fork back on the bike and got it right.
I used a rack mount belt drive engine, shimano cb-e rear wheel with 105 gauge
spokes- coaster brake. A x-fd sturmey archer front, drum brake wheel. Maxxis
Hook Worm 2.5 inch tires and slime tubes. I went 15 miles through the country
way and put it to the test. The soft ride gave a great performance ride and handling.
The rear wheel swing arm is strengthen by the attachment of the rear brake arm. I also
made a swivel attachment to the bike for support of the upper arm coming from the engine.
The bicycle holds true to its title of soft ride and I am very pleased with the bicycle. I can
get a picture posted as soon as I can borrow a camera again if interested.

Please do Charged - that sounds sweet! It's great news that the steering problem was simply a mismatched springer issue, no worries man - I woulda done the exact same thing lol

I second the request for pictures, if you can.
Also, I am glad you worked out the steering issue. An old roommate of mine had a 20" bike with a springer front end. That thing felt rubbery in the handling department.
I like positive handling, not a wandering flexi-flyer......

I shortened the seat post by 3 1/16 inches and added a classic
hair pin web spring cruiser seat. This turned this ride into a firm but
soft ride, like your floating with the bicycle instead of that roller coaster
effect ride. I have never experienced a ride like this on a bicycle before.
The suspension shock is rated at 650 lbs/in .
