Hello Marvin,
No the "trike" will not keep upright in it's current state when at rest. I have designed the trike to have the rear brakes activated by the left hand "hydraulic clutch" lever. This leaves me room to install a rear foot brake to engage a disc brake attached to the rear swing arm. This WILL lock the rear swing arms from moving. The design for the rear tilt lock is completed however I have decided to hold off on that fabrication until I have installed the batteries, controllers etc. The bike however has been through a series of "roll test". It appears to be very stable at slow speeds.

The trike is now "under power"!!

Very Very nice fabrication buddy...One small very minor critique though, and its nothing to do with your build more the comment you have on EV Album... i.e "First known dual rear Hub motor, Leaning, Delta style Motorcycle. (Tricycle)." It isn't, as mentioned above Carvin Marvin beat you too it :wink: his is powered by two x5 hub motors in the rear wheels and is also a tilting delta setup ;-)

Would LOVE to see some video of the bike in action.

EDIT: damn beat me too it Marvin hahaha... i was busy looking at the pics on EValbum before posting LoL... it is definately a neat bike none the less thats for sure ...

p.s welcome to the forum too johnhead@frontiernet.net glad to have another fabricator on the boards :-)

Welcome to the forum John. Amazing work. I think I spied pics of your machine with paint at a show. At the Enertrac tent? Pretty sure I followed a link or two from this site.

I'm curious is there another licensed road legal with tags Electric tilting trike capable of highway speeds. If not then it's fair to say John's trike is the first registered with tags (plates) highway capable (will achieve 70 MPH) Electric tilting trike. If there is another then I'll stand corrected.

First or not, John did a brilliant job designing and building the trike

She's been a fun project mostly for John, he brought it over to EnerTrac and we did the final wiring of the controllers and motors and got to take test rides on a fun machine.

I agree...but that is clearly not what is said.

""First known dual rear Hub motor, Leaning, Delta style Motorcycle. (Tricycle)."

^^Exact wording copied from EValbum...the statement is completely false whichever way you want to spin it. It is a fantastic build as said before take nothing away from that, now the builder is aware others have come before him IMO the wording needs to be changed to reflect what you have just suggested markcycle, it doesn't make the trike any less of an achievement in any way :-)

Markcycle seeing your the designer of the motor maybe you can clear up what the cause is of the chattering at 1.32min mark of the video when the bike is starting off? Also...what is the turning circle of the bike, if the turns in the video are anything to go by it looks like pretty wide turning circle? and does it have reverse?

I'd like to know how these tilting trikes feel/operate differently.

What benefits do they have over a regular bike? Can I go faster in turns? Can I turn sharper at lower speeds and feel more stable?

I'm looking for info from actual riders here, not theory.

I think it's great to see your hub motor being used this way Markcycle.

No I'm not a rider but two advantages come to mind easily. Traction and no need to balance at or near a stop. The second may be very important for folks with weak/damaged legs.

"First Known" has now been remove from the description in this site
http://www.evalbum.com/preview.php?vid=3367
Thank You for pointing this out.
The trike feels just like a standard 2 wheeler. The trike was designed to maintain a very low center of gravity. The availability of the hub motors for use in this design allowed more space in the "Body Cavity" for batteries, control hardware etc. This bike is also equipped with a foot operated lever that prevents the trike from tipping when at a stop. As with any prototype, improvements and redesign is ongoing. (It's now Winter in Western New York)
Mark has been INSTRUMENTAL in assisting me with this build. His Product and Customer SUPPORT is without a doubt the BEST I have ever had with any product.

Great build John. I don't care if you are first or not, I know making a tilter is not easy. Must be some awesome power with not 1, but 2 of Mark's motors.

Do you have any more closeups of the tilting mecanism, including the lockout? Do you have any video of really carving in the turns? The one pic showing you tilting it over gives an idea of how far over it goes, but I would love to see that much tilt in motion.

Do you have any acceleration numbers? 0-30? 0-60? etc


Thanks for sharing, and great build. I look forward to seeing where you will take this design.

The so called chattering is motor cogging. For some reason the camera seems to make it seem worse than it is. I call it the grunt. Many folks like the sound as the bike isn't completely silent at takeoff, you don't feel it in the acceleration. Depending on the bike and fairing design the sound can be tuned as crazy as that is.

As far as the turning circle for me my arms aren't long enough to completely turn the fork to its stops I can't even get close, but it wasn't design for me.

Yolk? which part is that?

I recently got a chance to ride the Zuumer standup scooter.

it offers 'return to center' and a bit of rear steering.

I rode it parallel stance like a ski, nice carving sensation..

Design concepts that contributed to the Yolk design for my "Stealth-E 3" trike came from http://jetrike.com/
The yolk is NOT simply a straight bar that pivots in the middle. It is designed in such a way that makes the trike "self centering". Today we had 9" of fresh snow in western New York. The maximum lean angle that I feel can be achieved may have to wait for a few month's! During that time I will be fabricating a battery covering and completing the "lean lock" assembly.

Hi John,
Great work! I can't wait to see more details once you get through winter. Since you set it up with self balancing, how much does the height of the COG increase with lean?

I chose a "self balancing" geometry that was "minimalist" as I didn't want the trike to "not lean" as I was carving corners. I have not tried to tip it yet however I am pretty sure that It would "fall over" given enought leeway. By changing the geometry of the crossbar I can modify this if it is necessary. I haven't measured the amount of "rise" yet either. I do know that it handles and feels just like a std. motorcycle at speed and at the angles that I leaned it so far. I do expect to be more agressive with it next year as spring arrives to western NY.

A lil late, but I wanted to congratulate John. That is one bad ass looking trike!

For a short "PHOTO ESSAY" of how I built the Stealth E-3 follow this link. Approx. two years from start to finish.
