:)

Here is my ideal of a kids/adults 4 wheeled bike, without the frame twist of a Streetfighter....... I have put the front end on a set of 3/4 bearings, with a 3/4 inch axile rod as the link for it all. Have test ridden a few times, and things seem to be fine, but mabe a little to responsive to slight curb inclines... I DON,T KNOW, maybe I am exspecting way to much from a light weight cycle. The front end is set to a 8 degree tilt, as 10 degree was seeming like to much of an angle for my bearing abled front end. Any thoughts on this, garage hackers? Is this way to much weight addition, complexity, for a possible soluction to frame twist?

Hear are some pictures of my latest project, nearly compleated. So let me know what you guys think. The rear end is set up just like the DeltaRunner, except is used 1 disc brake per axile. The seat has been made moveable also, just in case I give this new jem to my sisters kids, who live in Alabama. So I tryed to make her as adjustable to different sizes of riders as possible.

One more thing, I really have a tough time getting the front wheels 90 degrees to the ground. This is my secound build, and I seem to remember my first one having issues to deal with no matter how hard I try to sit down and calculate my front ends up before I welded them........ Is it the heat from welding changing them, or just my inabilty to get it right the first time. The right front wheel came out 2 degrees of from perfect, but the left front wheel is almost dead on 90 degrees... Man, this really bugs me.. lol Am I worrying to much about 2 degrees off?

Any way, here comes the pictures....

Thats exactly what I had in mind when I first came to this wonderful site full of wonderful people who buld wonderful things and give wonderful help. If you cant tell I think AtomicZombie is WONDERFUL. I am going to build one for my 5th bike. I know Ill build that many because I ahvent even started my first and I am already addicted!!! HEHEHE

Good luck an the finishing

Nice job. I notice you are measuring the angle across the tyre. Perhaps check across the rim. The tye could be making the difference. My wife's factory built trike has one wheel visibly out( if you look hard) but it doesn't affect the performance.

You also might want to measure it with someone about your same weight on board. If it is straight vertical 90deg when unloaded, you are probably at least 2deg out when loaded.

I almost did the same thing with my DR, but decided to make the Fox into a LWB tadpole. After seeing yours, I may just make an interchangeable front end. Nice job. For what it's worth, I just eyeballed the wheels on the tadpole, and it handles just fine. Darren's right. When you put a load on it, the angle may very well change.

Out 2deg on one wheel - unthinkable - scrap it and start over :jester::jester:

Looks nice - I would consider myself lucky if I had everything withing 2deg tolerence on my Kyoto.

Could you provide some pics of the front actually in a tilt position and in a turn - I am having a problem visuallizing how it works.

Gotta love a quad! Nice work, DK!

Personally, I think you're being just a touch too critical.
I'm something of a perfectionist myself, & I'd be BRAGGING that I got within 2 degrees! :)

Man is that ever looking good. I can just imagine how much fun you're going to have on it!

I wouldn't sweat the two degrees. You are using tools that are far more precise than many of us own. Brad's designs are pretty forgiving (and from what I can tell 'tested hard and put away wet')and as long as you are in the ball park they will ride great.:)

As an ex welder I know heat will warp welds. If this the worst warp in the trike you have done a great job controling warps.

trikeman
05-10-2009, 02:45 PM
I agree with the others - it probably won't make much difference. But, if it bothers you, you can probably put a small weld across the top of the tube and it will cause it to draw up as the metal shrinks more than it expanded.You may even be able to grind the weld off when you are done and have it stay in line enough to make you happy.

Thank you all so very much for responding. My mothier made me this way, if it wasn't perfect, then I had to do it again untill it was... lol But you know, most people would not see this 2 degree difference, But I sure can. Been really buzy this weekend, had a lot of things to catch up on around the home front....... When I get started on one of these bike projects, I cannot pull myself away from it. Its like I get taken over by the bicycle gods or something. Wish I could make a living at doing this, cause I sure love building them.....

At least no one thinks my bearing ideal for a floating front end crazy, thanks all 8)

I will be a fixing that 2 degree, can't help myself......

Take care all,

Forgot to mention I will be going under soon, on a new build. Just as soon as I finish this quad. I'm going to be a building a DeltaRunner for my wife, along with a new EcoSpeed Electric assist mid drive system for her. She can't pedel to long without her neigh giveing her proublems, and EcoSpeed seems to have just the unit I,ve been a looking for, to put one her new ride... Thank you GregLWB for opening my eyes to this incredible elctric system. ( I read one of your post with this info about them) It is very pricey, but I think it will fit the bill for her. Have all the parts on hand, so I'll be gone soon....

That's a sweet looking ride. I can appreciate your concern about the wheel camber angle. 2 degrees seems like a small number, but on a 20-inch wheel, I figure that's more than 5/8" out top-to-bottom. For a quad, if anything, I think you'd want negative camber (leaning IN at top). But what do I know, I haven't started my quad yet!

Let us know how you go about fixing that angle. I like your angle protractor gage. What do you call it?

That Angle Finder I found at my local Lowe's store. Its made by Swanson. Have to leave the face of it off, as the paper background has warped setting in my garage over time, and I keep pressing it back down with my finger......

05-13-2009, 09:26 AM
Well finally got around to fixing that 2 degree proublem by useing my angle grinder with a cutting disc. Cut a notch into the stearing tab, thin enough so that I could persuade it to move with wheel on, and welded it back together like new. I figured I would have little to no heat warping this way, and it worked great. All is right with the front end, now..... 8)

Have to tweak my handle bar set some, as there is no spare room between legs and bars. Just to close for an adult. But this shouldn't take long to do... Thinking about adding an extended goose neck, back towards the rider, maybe adjustable height... Will see how it goes...

A couple of pix of fix cuts.... The cuts where done on both sides, just not in these pics...

That is a great way to "fine tune" an angle. I have used this system many times, sometimes even planned to use it knowing it would be easier to get a perfect angle later. There is probably a real name for this technique, but I have been calling it the "pie slice" system.

Lmao brad funny thing is remember on my wifes streetfox build, I had that slight toe-in problem it was like 2 or 3 degrees.

I used your pie-slice technique, when wife asked how I was going to fix it I told her I would take a slice of pie out of it and reweld LMFAO

Ok !!! So this is the end result of my 4 week marathon at building this little quad... Took her for a spin once around the neighbor hood, right after I took these pics... Stated to rain, so hear I am posting.... Boy, I forget how much work it is to pedal around on a bike, I need a motor !!!! lol

Sweet, a very clean machine.
Is the pulley there for a reason? as it looks from the pics as if its not required and you could get a straight chain run.

05-15-2009, 10:14 PM
I'll see what I can do about those pics for Kat, Brad. Thank you so much for giving us all such a great place to learn how to make these things come to life. I could have never been able to do it without your place, you and Kat rock !!! This has been a kind of therapy for me, as I use to work in the automobile part suppler industry, and felt that it was in my best interest to take an early buy out. This keeps me from being depressed, to say the least, and I can't thank you enough for that.......

savarin, the pully I added just to keep the chain away from ridder a little bit more, as I will prouble give this ride to my sister kids in Alabama. Haven't given them anything before, and maybe this will make up a little... I do think of them from time to time. 8)

Cheers all, and happy trails to all !!!

That's a nice little quad you've built there. Should turn a few heads.
I think the kids will love it if you give it to them. Only prblem I see is different size kids reaching the pedals. Might need to make the seat position adjustable.

Thanks John,
But the seat angle, and possition are fully adjustable, as I have allready considered that proublem. The paint will prouble get scuffed up when moveing the seat clamps ahead or backwards, as I left as little space as possible for them. ( Wanted a tight fit ) Didn't want seat rocking back and forth while pedeling down the road.......

Thanks for input, though .... 8)

Very nice build. Color looks the same as my Marauder. (Rusoleum Professional Enamel?)

I like your steering linkage. I may want to incorporate something similar into my Street Fox, but with USS. I'd need two more rod ends though, as your system uses six total.

I used some floresent red orange paint as my first 2 coats, and didn't like the way it was looking.... So I painted over that with Sunrise Red... Looks like maybe the floresent red orange is bleading through a little, but thats ok... I like the end result... Both cans I believe are Rust-Oleum, at lest the Sunrise Red was. ( Gloss Enamel.....)

It's nice to see another version of the tilting front end. Your excellent video clearly shows how it smooths out the rough terrain.

You're in an elite group since you, Sir Joey and I are the only quads I've seen here on AZ with a "Rock 'n' Roll" front end.

Be sure to post pix of your next project.

I was looking through the SF threads for any discussion about the angle for the front axle mounting tabs. I know it can vary, but I figured there's a ballpark angle that the tabs can be ground to, to get close. The technique for fine tuning here is good!

Hello Ron, I was just admiring your red quad on the AZ gallery. I'm new to quads and am ready to build my Street Fighter. I really like your seat design. Do you have any photos you could share that would help me build one? I have a bad back, and think the radical recumbent design would bother me. Yours looks comfortable. Did you have to change a lot of stuff in order to make your main beam parallel to the ground? Thanks for any help you can give me. This quad will be one of my main forms of exercise and I really want to incorporate all the best features I can and get it right the first time.
Ted


Hey pappy,

Sorry to be a little slow to respond to your question, have been away from home. Had to deliver that bike to my sister in Alabama......

I used the design from the Deltarunner for the back end of that bike, and the front end design of the StreetRider for the front.... The angles work themselves out while I was in the middle of it all. Just have to keep the main boom pearalell to ground. (forgive my lack of spealling issues)

Don't have any real close up of seat design to give you, as bike is gone. All I wanted was 2 things, though. A little tilt in the bottom of seat, and a adjustable backrest for the ridders to be able to sit to there most comfortable possition.....

The seat tilt is easy enough, just take DeltaRunner design for seat, add the desired tilt wanted, and cut the meatel to seat boom support to correct length. I think more of a tilt would have been better from that one I made, as seat was not to good on tailbone comfort after a few test rides I took with her, so I tilted back rest a lot more back to compensate for it some. (not perfect)

The back rest was made adjustable by a couple of flat iron pieaces welded to seat bottom, hole drilled through them, a bolt to tighten down throught that. Then I welded two 1/4" tie rod ends (left & right threaded) to back rest boom, and seat bottom boom with the appropeate pieace of rod in between them to make it adjustable.....

Hope this helps get you started, and let me know if I can help any futher...
