Well I decided the rear leaning was not workable .Looks like reverse trikes are 3 times more stable based on my modeling. (this from the same guy who thought the leaning rear trike would work) lol.I started taking it apart today and now I need a good rear swingarm, the two lower frame rails and a good seat or pan.Five months of fun I guess but a disappointment.Mayb e the next try will be better.

Still a worthy project . Not a failure if you learned something .

You are right. I did learn a lot.

Some one on Ebay has California EVE frame lowers. Will they fit my convert?

The Tilting Motor conversion is pretty cool, I could actually be tempted by that in my old age.

Keep after it, you may come up with something that really works. If you give up now you'll have a bunch of specialized knowledge just laying around in your brain

You don't know what you don't know until you try it out. You've got the fabrication skills and desire. Keep on the path!

I had a lot of core failures while I was building mine. It took three years to sort out. What is the basic flaw? I'm guessing the rear axle length is too short for the length of the trike, and the weight distribution isn't right, but that's just at a glance. Those things are fixable if you want to keep going at it.

You are to be applauded for at least trying.

In the pile of parts I've amassed for my T-something project, I've ended up with 2 swingarms.

Since I have a couple of cast wheels, I'll be using a rear disc, and the swingarm with the brake stay(those of you more knowledgeable correct me if I'm wrong)

You can have the other cheap, or trade maybe?

The stay is for drum brake. The disk swingarm has a lug near the axle hole for the carrier plate.

What cast wheels?

It's a constant learning experience. This guy figured out how to turn a hi-powered mono wheel vehicle into a drag machine ...... with skids!

Skids, way out front!

Everyone will want one now.

According to RK you need to keep the one wo the stay.Are ther identical except for that? Will it work on my convert?

gearman · « **Reply #17 on:** July 14, 2017, 09:43:14 AM »

RK, the big flaw was that I only had 100 pounds on the front wheel. Going down our bumpy roads it felt like I was only riding on the rear wheels. Scary. The rear engine idea just could not be fixed.She is all apart now waiting for the future.I might use the locking tilt mechanism for the parking brake.I was looking at my posted pictures and thought ,I could have a much crappier job with less work and still found out it was flawed. LOL

rodekyll · « **Reply #18 on:** July 14, 2017, 04:48:09 PM »

So why not flip the rear axle around and make it a mid-engine?

After watching Rodekyll perform miracles on his trike, I bet he could make your rig work.

Chuck in Indiana · « **Reply #20 on:** July 14, 2017, 05:18:17 PM »

I'd go for the mid engine idea myself. The weight and balance on prototype number 1

just didn't get it.

I couldn't say for sure, they look identical except for the tab for the stay. Those more knowledgeable? I would think you could make any Tonti frame work. Not to hijack your thread, but Rodekyll, these are the wheels I plan on running, on a 75 850T project.

Let me know when you figure out what you want to do. Neither swingarm is going anywhere soon, when I figure out which one I'll need, you're welcome to the other one.

rodekyll · « **Reply #22 on:** July 14, 2017, 05:29:07 PM »

I think there is also a tiny (mm's) difference between the drive shaft side trailing arm. That means there could be alignment problems with various final drives.

But the disk brake arm has no brake stay lug and the drum brake arm has no caliper holder lug. So mods would be needed at that level at least if you start out with the wrong one.

Pat -- thanks for the pic. I have a curiosity about who's doing what with cast wheels.

I think I would have a hell of a reverse speed. I also would be sitting on to :grin:p of the engine.

Depends on how you flop it.

Rick4003 · « **Reply #25 on:** July 15, 2017, 04:58:49 AM »

It could be interesting if you could make something that retains the original position for the motor and come up with some transfer system to the rear axle . Still try the leaning idea but with better weight distribution.
The thing that worried me the most about the original prototype was the rear position of the engine and the fact that the mass of unsprung weight was far higher than the sprung part of the trike.

How about hydraulic drive to the rear axle? If you focus on having a good flow in the system you might not loose too much energy on the oil.

It would have to be upside down.Pinion would be on top. Right?
