TreMoto Monstrosity leans into the future

Galleries -


Created to prototype a system that could be retrofitted to any two-wheeler, the TreMoto Monstrosity is the product of two University of Mississippi graduates who want to turn their senior project into a viable business. Similar to the front end of the Piaggio MP3 500, the TreMoto Monstrosity is intended to work just like a regular motorcycle, just one immune to lowsides. Lean angles past 45 degrees remain possible, but the system really comes into its own in slippery conditions where the added grip and stability drastically improves safety and speed.

The parallelogram front suspension adds around 35lbs to the overall
weight of the Monster 620ie and, like the Piaggio, employs a lean
locking mechanism that enables the bike to be parked upright or on a
slope. Unlike the Piaggio, the lock can also be employed on the move,
something its creators say can prevent high sides when the rear wheel
steps out.

Helping to keep that additional weight as minimal as possible is a
Kayaba rotary damper similar to that used on the Suzuki TL1000S. TreMoto
promises they’ve made theirs work however, ensuring that the damping
doesn’t go off as heat builds.

The two guys behind the project are Eddie Smith and Rob McIver who are
further refining the suspension, raising investment and figuring out how
to put their patent-pending front-end into low-volume production.
Describing the riding experience, they say, “The back end slides like a
flattracker, and is highly resistant to highsides. Low-sides are
basically impossible, even if you wash out both front wheels you hit the
lean stops rather than the ground. You can lock up both front brakes
without falling or loss of control. Having two front wheels is like the
auto-balance feature from a Tony Hawk video game. It’s sort of like a
Piaggio MP3, but replace the ‘scooter’ with ‘Ducati.’”

We haven’t ridden the TreMoto, but we have spent a lot of time with
Piaggio MP3 500. You ride and steer that just like a regular
large-capacity scooter, but the two front wheels add incredible
stability without sacrificing agility. That machine looks to have a far
higher center of gravity than the TreMoto, which does mean its
relatively easy to tip over when you’re sliding around offroad. The
wider track and lower stance of the TreMoto should eliminate that issue.
No additional steering effort or power is required to turn the
handlebars and you countersteer just like on a regular bike.

TreMoto is a small startup just getting off the ground and are looking
for your feedback on their project. Despite the massive hurdles they
face readying this concept for production, Eddie and Rob remain upbeat,
say, “We have eBay parts all over, but we’ve stolen crowds from
Desmocedicis and Tesis at Daytona.”

    Looks familiar…

  • Shawn

    I like the look of this. Although there are other companies out there doing the same…. just maybe not as nice looking.

  • Mark D.

    Very cool! This could be just the thing to get more ‘merican’s out of cars.

    What size are those front tires? I wonder if they could go even skinnier on the front tires, making it even quicker side-to-side.

    The most important question, though; can it wheelie?!

  • Random

    When they start to look like the Yamaha Tesseract, I’m into it.

  • HansP

    That’s a Brudeli rip-off…

  • brettvegas

    That’s the kinda fucking trike I’d ride.
    Bob Snevies(sp?) Fucked around with quite a few trikes. Crazy as a shithouse rat, that gyuy.
    The polaris trike, whatsitnamed, is a fucking turd.
    Inside front wheel lifts in a turn. Very low lateral g-forse capability.


  • AGP

    Well, they got the name right at least – I think I’d rather take the bus. Perfect for splitting lanes, though… ;)

  • BL

    because people who are too afraid to ride a two wheeler are all about drifting a trike?

    i don’t get it.

    unless you’re disabled or old or whatever…cause then i get it.

  • Eddie Smith

    Thanks for the comments, guys. Admittedly it’s not for everyone, but it’s wicked in the rain and on gravel. Nose-wheelies only, but I promise the Hypermotard version we’re building will hoist both the front wheels.

  • Ray

    I think this thing would be loads of fun. I’m looking at selling off my Speed Triple because I’m moving out of town to a place that’s miles down a dirt/gravel road. If something like this were available, I’d be very tempted to keep the ST and modify it to make it stable (and wicked fun, I’m guessing) in the dirt. Can anyone say 120hp scrambler?

    Nice job, guys.

  • Rob McIver

    Thanks for the publicity Wes. Eddie and I really appreciate it.

  • Cajun1958

    Is the TreMoto a graduate thesis project? If not that’s an impressive undergrad program you’ve got at the UM. Anyway the bike looks interesting and an off-road version would I think be a lot of fun as well. I’ve seen pix of the Brudeli just baking it down a fire road and backing into corners like nobody’s business. Very nice job fellas it’s good to see college kids putting their education to good use!

    • Rob McIver

      The TreMoto was invented during our senior year as undergrads. Neither of us are currently enrolled in graduate school. Thanks for the feedback, our next Hypermotard-based prototype will have even more of an off-road focus.

  • Ken

    So is the aim to sell it as an aftermarket conversion for any appropriate existing motorcycle or are you wanting to market a whole trike?

    • Rob McIver

      The aim is to market a whole trike, centered around retrofitting an existing motorcycle. Right now, we are focused on bringing the TreMoto Hypermotard to market, but we are open to doing one-off customs as well.

  • JR

    Very cool! I would love something like that. I’m sure it’s solid as a rock in the rain!

  • Jbo

    Awesome! Just imagine what 4 wheels could do!

  • Andrew

    Great job guys its never easy getting a start-up going. I had a Hyper for nearly 3 years and loved every second of it. Having a version that your describing would be amazing, looking forward to seeing it in action.

  • james

    I love anything three wheeled! This design is very dynamic and I hope great success for this start up. Cottage industries “bolt on trikes kit, dirt bike to road legal kits, wheel chair side car motorcycles ect…” find an important need within an industry. My all time favorite trike is a Honda Gyro-X ….

  • coho

    Go, Rob & Eddie! Reverse trikes are made of awesome.

    Slick bit o’work that Monstrosity is.
    More, please.

  • Red Rob

    This is truly one of the SWEETEST vehicles I’ve ever seen. The the increased stability that makes a highside nearly impossible is the mark of some KICK ASS engineering!
    All in all there is only one word to describe this trike:


  • BL

    i guess i shouldn’t be surprised, but i can’t help it.

    the readers of HFL hate high speed sportbike riding, but love bolt on trike kits.


    don’t get me wrong, props to the guys building it…that’s cool, way to do something with your lives and best of luck to you….but don’t quit your day job.

    the road to moto obscurity is paved with ideas like these…

    • coho

      We love us some high speed sportbike riding, it’s some fcuknut doing 180+ in traffic in the dark that gets our angry on.

      In the eyes and minds of the non-moto portion of the population that sort of thing reflects badly on all of us murdercyclists.

  • Botswana Meat Commission FC

    Something I’ve been wondering…

    I know that 4-wheeled ATVs are NOT road legal in most states (there may be an exception in, like, Wyoming or Montana) and that laws basically require a rear differential on 4-wheelers instead of a chain/sprocket final drive.

    So why then are trikes with chain drive DOT legal?

  • brettvegas

    BMC-FC, I’ll tackle that:

    It is a mass thing. Trikes cannot mass over ~one ton. The tires don’t work on a trike that is one and one half ton. The law has to include them, but has a tough Time determining WTF the vehicles ‘class’ is. Basickly the law says ‘fuck it, it’s a motorcycle, move along, nothing to see here.”.

    I must agree with BL, don’t quit the day job.
    However, following one’s dream is never wrong.

    Find a salesman, and get him to find ya money.
    Don’t work for nothing.

  • Scottie

    I’m still waiting to see where Yamaha goes with the Tesseract. I like the narrower stance.

  • Brian

    seems “interesting” .. not really what I would want.
    Seems like a lot of steering input. … even with lean , I wonder about its turning diameter capabilities.

  • FTroop

    I love it. After my accident two years ago where my yamaha (and for a short time my body) was decommissioned by a Camry making an illegal blind turn, my wife has been reluctant to let me get on two wheels. She likes the idea of a front wheel trike though and this could be a great option for me. Eddie and Rob, count me interested…and Wes, how did I miss this site?!
