So I was in a rush with my buddy to finally weld the spincycle together. I had all of the parts put together and as we went I made adjustments, which after fully assembled I realized was a bad decision. Here are the mistakes I made for those taking this on. I went with a more open angle on the front third of the bike. Reasons this was bad, was because I made the handlebars further away and changed the positioning of my bike so that the castors angled back slightly also putting the weight distribution to the rear. I decided to increase the length of the piece you sit on because I am a big guy and might like room. This made it so the pedals were too far away. The recommended length was plenty considering the angle you will be sitting in. Lastly the rear bar ended up offset slightly, so the bike would only spin, never move forward. Then the last thing that happened was the angle iron bent, but I realized we did not weld the underside of the rear bar to angle iron.

So now I need to figure out how to fix it. My plan for the front angle is just to chop it shorten the front bar a bit and shorten the angle making it closer to the prescribed angle. Looks like in the gallery a few people have gone about 90 degrees for this angle. For the alignment of the rear I considered cutting it off and placing it underneath the bottom piece instead of notched. I wondered if lowering the front 5 degrees to get the correct angle on the castors would be enough. Other option is to grind out a side and pound into place and reweld. Finally I believe the angle iron bent from the lack of weld under the bar but I was going to weld additional plate to reinforce underneath.

I was so excited to get on the thing and ride it but it went all wrong. I knew as soon as I had it assembled, the lower rear angle was wrong and would cause me trouble, but didnt expect the bend of the angle iron. guess I am 230lbs or so. glad I started with this build and not the streetfox I have all the parts for. Hope next time it goes better. Felt like a kid that broke his toy. In the pictures I was tryimg to figure out seats. Found 2 butt seats from my boat that I knew I kept for a reason. My wife says it looks silly though. I guess a 230lb guy on a big wheel looks kind silly too

First question you got to ask yourself when looking silly, are you having fun? If yes then what does it matter? It is you wife that is missing out, not you. That's the whole point to have fun.

As to repairs you have been reading Danny C signature have you not. Weld, Swear, grind off and try again. A grinder can correct a lot of mistakes. And so can a welder. It turned an ordinary bike and turned them into something fun. Yes?

04-06-2015, 09:05 AM
Well the building is fun riding was a disaster. I have never had a problem with looking silly, my wife just thought I should make a different seat. Fun stuff for sure just thought I could put a notch on the belt for project 1. Hopefully soon.

04-08-2015, 11:31 PM
Well yesterday I took the cutting wheel and ground out the welds of the rear bar except 1 and knocked it square, so that chould be ready and I cut my new angle on the front end to correct the weight distribution and seat angle. I set it up un concrete blocks to simulate heith and placement of the steering tube. Wasnt nearly as bad as I thought. Now just have to wait to take it to buddies house to weld. I have to say I had waited to use a chop saw but I really liked cutting with the cutting wheel on the grinder. Thats how I chopped bikes, but thought I would prefer the chop saw.

04-09-2015, 02:29 AM

Keep at it and it will soon be ridable.

Chop saw and grinder are not really interchangeable , the chop saw is great if you have large lengths of virgin steel and want accurate parts duplicated.

It is little use cutting frames apart or items to small to safely clamp.

The grinder is great once you have the skill to use it accurately.

As someone once said ' I am not useless. I can be used as a BAD Example '.

04-09-2015, 07:33 AM
I like the front end steering set up. Question is will the wheel hit your leg when turning? This is a question I have been pondering and thinking about using on my Ninja Turtle trike project. Looking at what you have makes me visualize a Ninja Turtle trike.

04-09-2015, 01:20 PM
The wheel can rub that is why brad fabricates a cover in his plans over the wheel. I had to adjust mine to make it more upright. I had a great idea if I ever make another. Look up leaux racing trike on you tube. They use headtubes from kids scooters and fix 1 wheel to a handle allowing for very precise steering. If you look at a kids scooter it will make since after you watch the video. Because the rear wheels are castors you dont have to turn the wheel dramatically for my current one. I am probably not the real guy to ask but mr. Idaho I am glad to answer anything you have to ask with my current understanding of the project.

Well, I had a great day yesterday, and made good progress. I finished the spincycle frame adding the needed supports and correcting the angles. I still need to grind a bunch, but otherwise I think it is right this time. I then got to start my streetfox. Guess I will be taking a break. for a little bit as the schedule is busy over next few weeks. Too much fishing and morel mushroom hunting to focus on the bikes. I assembled the spincycle tonight after work, will give an update tomorrow about the ride. Feels much more comfortable and moves great the little in the garage it moved. Cant wait to be riding it around. Now I have to decide on paint.

04-15-2015, 06:53 AM
If it were me, I'd wait on paint for a few rides first. Make sure of the fit and welds before painting. After all is not the title of this thread "trials and errors".😯
Paint can go on later as it is much easier to grind and reweld bare metal. But it is your build

04-15-2015, 10:04 AM
Oh I don't think it will end up painted soon at all. I will be riding it

Holy you know what this thing is fun!!!!!!! It is a serious workout but you can get going pretty fast and then all of a sudden wham you are spinning all over the place. WOW! If I spent an hour on this every day, there would be no need for a gym. Brad and others, I can't thank you enough for the fun that will be had on this. I felt like I was 5 years old cruising down the street on my rhambo big wheel. Now I know it wont get paint for a while, because I won't want to take it apart

Thanks for sharing!
Glad you are enjoying the ride. Brings a new meaning to "heading out for a spin".

Not sure why you'd do the Castor mounts like that, when you could simply drill a hole for the stud through the square tube, then open out the top hole to give clearance for the socket that fits the nut! :smartass2:

04-21-2015, 08:59 AM
If you
drill a hole for the stud through the square tube, then open out the top hole to give clearance for the socket that fits the nut!
then the castors would have a thin metal mounting pad that would not be very strong. IF he welded say a 1/4" thick bar stock on the bottom side of the box tubing then you could drill a clearance hole for the nut. IMO
QUESTION about this spin cycle - this has me contemplating for my Ninja Turtle trike but wonder if the steering could be slowed down or a better mouse trap to avoid having the front wheel possibly hit the child's leg.
BUT having second thoughts on a 6 year old riding a spin cycle??

04-21-2015, 04:35 PM
The reason I made the mounts for the castors that way was because I had already welded the 1/8 inch angle iron to the bike which you can see in the first pictures and it bent. I realized we hadnt welded the underside, but felt it needed more support. I had considered welding a piece under, but figured why not be sure that it is strong enough. Thats why I adeed the pieces I did. We talked about in future ones just drilling through square tubing. First bike I made I followed the plans for support and added where I needed it. My plan is to cut them at an angle or round them off before paint. I will say for a 230lb guy this bike is solid. I believe the way the mounts were, we made the best decision to give it the greatest strength. I will tell you, they will not bend again. I also have to say with the 2 boat seats I could take a nap on the bike it is so comfortable. Mr Idaho, I am telling you take a look at the trike I saw on youtube. The scooter headtubes with a handle on one side would give better control. There were also a few guys who made them with big wheels in the front.

04-21-2015, 05:11 PM
I meant there were a few guys on here that made them with the same big wheels on the rear as the front. The spincylcle as it is would be a little scary for a kid, but with a few modifications would be nice. My neighbor who is a little over 6 ft. Has almost no leg scrub where my wife who is 5'7 has more. The taller the person there knees bend over it. So you could find a way to bring the wheel closer or have the person sit up higher.

04-21-2015, 06:02 PM
I viewed the leaux racing trike on youtube and I am inspired to rethink my plans for this Ninja Turtle trike. I like the Leaux trike and somehow connecting the handle bars to one of the the rear wheel instead of the handle connected to the castor.
A version of a spin cycle could emerge.
Brakes are an issue as I don't want to utilize hand brakes. Thinking utilizing the rim w/ coaster brake for the front wheel that is non rotational (no steering capabilities, only pedal power) then the handle bars control one wheel in rear OR go with rear steering as http://www.target.com/p/mobo-triton-pro-adult-the-ultimate-three-wheeled-cruiser-20-blue/-/A-10935949?ref=tgt_adv_XSB10002&AFID=bing_pa_df&LNM=10935949&CPNG=Sports&kpid=10935949&LID=14pbs&ci_src=328768002&ci_sku=10935949

04-21-2015, 06:26 PM
Another option!!
Just viewed several videos about a FUNCYCLE. It utilizes tilting front wheel for steering. Not sure how it works but looks like it turns very easy and tight.

04-22-2015, 12:30 AM
I had just seen one of the funcycles for 150 on craigslist. There is something very similar at toys r us near me

04-22-2015, 12:41 AM
. . . then the castors would have a thin metal mounting pad that would not be very strong . . .
Most castor wheels have a fairly wide mounting, it's not the stud that takes the load.
It would be well supported by the full width of the tube (and therefore by the sides as well), which would be plenty strong enough.
The stud is basically just holding it in position.

04-25-2015, 09:26 AM
Call me crazy but am thinking of a "spin cycle" similar to the Leaux trike but using 10 inch wheels from HF (#62388 or 30900) as rear wheels but configured as castors. The handle bar connects to the right rear castor similar to the crank steering on the Leaux trike. The front wheel is a 20 inch wheel w/ coaster brake driven by a crank set.
Hopefully the 10 inch wheels will slow down the spin effect seeing how a 6 year old is riding this.
As for fame construction, contemplating 1 inch box tubing 12-14g.

So I made a few changes to the hardware I had on the bike and man what a difference. I will say it made it less unpredictable which takes away from the craziness a bit, but made it a much better ride. I decided to try a different crank and figured why not try a smaller wheel. My thoughts where that this would increase the angle of the castors making it more likely to track straight. It really did. It took the bike from a culdesac bike to one I could ride around the neighborhood and the park. Decreasing the size of the crank and the wheel made pedaling a lot easier. It still does great spins and by shortening the wheel base it is more responsive. I rode today around our neighborhood circle about a half mile and later rode to the park and around a 1.25 mile loop. It is really fun to try to manage small hills with turns. I was able to drift the hills and not lose control, I just had to keep the front wheel in sync with the back 2. I do miss the 20 inch wheel, but the new ride will help me use it much more. I kept up with my 7 and 9 year old on their bikes. Anyone who has made one of these and put it away should consider it. Great family fun on the bike today.

Pretty cool Slippy.
What size wheel did you go to with? Hard to tell from photos.
Sir Joe had a switchable rear. Coasters to wheels on his.

05-25-2015, 10:21 AM
I dropped from 20 down to 16. As far as the crank I would have to count teeth. It is about 2/3 the size

Finally got the spincycle painted and ready to roll!!!! I have ridden it all along but had to take it apart and finish it. Maybe a few touches left, but really like the trike!!!

08-03-2016, 02:32 PM
My guess is you were having too much fun riding it to paint it. :rockon:

However now that it is painted it looks to be just as much fun, and it looks great. Thanks for sharing.

08-04-2016, 10:19 AM
You are right dtd, too much fun riding it. Glad to have it complete except for a few fun touches here and there.

One more finishing touch. I was so confused with the decals Emma sent. At first I believed them to be white, but when I peeled it back I saw black. After I put it on the streetfox I realized they were white, so I could use them as previously planned

"Thanks for the plug"

It was a strange but durable white vinyl with a dark layer in the construction , I got a huge roll of it and it is "nice to cut" as well .
Just cut a few black ones for my next project which will be unveiled soon - until then you will need to wait

How are you cutting these Emma? Presumably you have access to a Robocutter or the like.

How are you cutting these Emma? Presumably you have access to a Robocutter or the like.

Being retired or is that just tired

I have a Rowland plotter/ vinyl cutter , I am happy to cut decals if required see the thread below and PM me , dispatch time is a few days but delivery depends on the postal system but it works out about 10 gbp for 2 pairs of AZ logo shipped with post/packing


Smallest I can do reliably is 10-11 mm 3/8 inch high as the cutter blade does not track with the cut .

regards emma

08-09-2016, 10:41 AM
Thanks Emma. My SIL has a cutting machine (she's in the UK, and we're visiting in a few weeks) If I can find some vinyl there, I'll get her to cut some words for me.
