My sikk ss aluminum fat tire cruiser build

[Defjr333]

Cool looking build, you should look into upgrading to a Phaserunner controller and 72+V battery pack. Night and day difference.

Never mind, a useful skill called reading helps, the stock seat post is stamped with the diameter, 30.4 mm.

Do you recall what size shim you had to use for the suntour NCX?

Hi JVG, I have the exact same bike. How did you port the bottom bracket?

This is an old thread and JVG has not been active in a while. A lot of builders have had this problem. A Dremel or a small drum sander on a drill can smooth out burrs on the inside of the BB. Never force in the BBSXX you will have a hard time getting it out. Don't forget to blow out the grit. That can bind you up just as bad.

This is a theory of mine and I have no proof. Here are 4 forks that take interchangeable steering tubes.



The links http://www.bikeman.com/store/merchant.mvc? link for steerer tubes http://www.bikeman.com/Steerer_Tube.html



These are not fat bike forks however I am quite hopeful you could fit a 3.00 and maybe a 3.50 X 26 into the one I linked to. Now could you press this steering tube into a Rockshock? Probably not. Could you machine/weld a bushing on to this steerer to fit a RockShock? Probably. There is also the probability that this steerer could press on to the $90 Luna fat fork.

So who is going to be the one to figure all of this out? It is on my schedule but not until around June. There I am giving you all of my secrets........calfee.

I have the SIKK bike that came with a rear cassete and metal frame. Not the Single speed and not the aluminum frame. The steering tube is definitely 1 inch. I would love to find some downhill style forks without having to weld a new steering tube on.

[JVG1967]

Do you have the same frame as mine or do you have the standard model? I think it's called the UFO fat tire cruiser. Look at the springer fork at the bottom of this page: https://squareup.com/store/Sikk/

From checking the Sikk website I only see that front fork on a different model frame

which looks to be a completely different steering tube.

[SDharlie]

So what are my options. To cut off and weld on a new steering tube that will accommodate better options for forks?

[JVG1967]

Doesn't SIKK make a springer front end for the standard cruiser? That's where I would check first.

[JVG1967]

That fork is only $1150.http://vintageelectricbikes.com/prod...n-fork-upgrade

Yeah, um, not happening

[g725s]

Are you meaning to say that the steering tube is 1" I.D. ? Is not the Sikk bike frame able to accept a standard shocked fork?

Help with forks on my SIKK bike. I too have a SIKK bike but it the steering tube is only 1" thick and I cant find too many options for front suspension forks. Any info would be greatly appreciated.

I have the same problem with my Electra and I have been trying to think of an easy way to modify the frame for a 1 1/8" steering tube. Then I saw a post over on http://www.bikeforums.net/beach-crui...ruiser-26.html The member there had a 1 1/8" threaded tube welded to a straight tube fork to keep factory quill stem.



I think our best course of action is to get a fork and modify it to the bike and not the other way around. Of course a careful plan is needed because the price of a fork, machining and welding could be the price of our basic bikes.
