Easy, that bike just keeps getting cooler and cooler!

Easy I took some more pic's of the bike, I am liking the bike more than I did before I put the motor mount on. I am going to try and get a stiffener over to the head. Ill keep you posted. Have fun, Dave

PS: This bike was dumped in the park, that I work at.

Looks good Dave. You lucked out finding that bike because it doesn't look like a cheap one. I was going to tell you to add a top mount bracket but it looks like tank is in the way. I wish I could install a tank like that on my bike. How big is it, 1.5 gallon?

Dave, where'd you get that tank? it really looks good with the geometry of that frame.

I am still fascinated with the George Wyman bike of 1902 and I would like to have something that looks like it, this is as close as I can get. I got the tank from Dax but he is out of them now and It looks like they are not getting any more. It will only fit a frame like this. The problem I have had with this frame is that it is so large that it gives the engine a lot of tubing to shake, and it makes it hard to get it to ride smooth. Have fun, Dave

From the looks of it, your bike frame is probably a 20 or 21" frame.

HI Easy,

I was reading earlier in this thread that you locked out the rear suspension because it didn't work right....what exactly wasn't working right?....I hope it isn't a design flaw or something because I recently bought a GT LTS frame like yours for my next build....

Thanks!

Andrew

PS - I think I'll have to rig up a chain tensioner in case the chain gets too slack when the suspension compresses....

Andrew, The chain slacks too much during the suspension travel. One of the pivot arms needs to be moved to the center of the motor sprocket. I think if your using Pablo's Jackshaft kit you won't have to worry about moving the pivot arm. I think this frame is idea for the Jackshaft. I was going to use one but I would need to fabricate another bracket. Also I feel a little hesitant to use the thin bike chain for the 5.8hp motor (soon to be upgraded to a 9.4). However, I think you should be fine if you’re using a HT. Hurry up and get that project going Andrew and don’t forget to post pics!

HI EZ,

That's what I thought was the issue...the chain slack...I did buy a kit from Pablo so maybe the derailleur will take care of all that....

I was going to put Pablo's kit on a disc brake bike I recently picked up (I bought the bike to tinker with the Top Hat adapter) but when I ran across the frame like yours with the full suspension....well I just couldn't resist...I'll have to wait another week or so until it gets here (unfortunately it was a bare frame more or less so I will have to start searching for things to make it a bike...luckily I have a few "donors" around.....still have to get the fork tho....

I'll definitely post pics!

Thanks!

Andrew

Wouldn't a properly placed spring-loaded tensioner (or two) get around the chain slack issue?
