Uturn Freeride All Terrain tilting trike
Вставка
- Опубліковано 9 лют 2025
- The construction and the tests have now been completed, as I had invented a superior implementation of a tricycle with the obvious advantage of tilting and comfortable, off-road riding. Uturn allterrain tilting trike has a rear system suspension leaning mechanism that is based on an idea I had years ago. Its implementation was a very difficult process, but I succeeded in proving that the basic working principle fulfills its goal.
The suspension trike seen in the video is commissioned by "Cekta", a film equipment company. The aim is to carry cameras in the rear, as well as a passenger. From now on, my goal is to build a lighter model with some transmission improvement, so that anyone can buy it. At the rear, in addition to the suspension and tilting mechanism, there will be a frame mount design for cargos or whatever else suits the buyer’s needs.
More videos that will provide better views will become available in the near future, while I will also improve the basic version of the bike!

A new version of this unique tricycle is live on Kickstarter now!

Unbelievable result! Congrats!
This is absolutely perfect
Awesome invention, Congrats!
Love it - maybe get ride of that rear derailleur for an internal for less mate. Or even change out the chains for belts.
Cheers
Great work....
Φίλε είσαι άψογος! Πολύ ωραίο!
You could use this suspension concept on a recumbent tadpole trike and be lighter with only the standard single drivechain system. Leading arm suspension for the anti dive braking characteristics and twice the grip on the steering- we all know what happens on a normal bike around a corner when the front wheel slips!
Front wheel drive for snow would be perfect
Hi ... where to buy or can be order by mail? Very interesting to ride.
What was your idea of not putting the two wheels in the front?
this is really cool. I'm guessing the counter rotating motion of the arms is accomplished by a sort of locked differential where the arms are mechanically linked so that they always counter rotate. I'm also assuming that each arm has within their respective pivot shaft some sort of torsion spring that allows each arm to "hyperextend" in order to absorb shocks and sudden changes in wheel elevation. I'm also guessing there's a similar sort of differential between the two wheels in order to drive them both at the same time. either that or the drive shaft is solid and each wheel has a freewheel that can let the outer wheel "fall behind" inside wheel gets the power when taking turns. I can't wait for you to have refined the design enough to let us see it.
When will U turns be available and how much?
The basic version will have two electric motors for each of the rear wheels for better traction on off-road routes. so will be a hub motor with no chain and I believe be rear two wheels will be more closer each other not so wide like long tail back frame. You will have another version with a mid drive motor with belts on the two rear wheels. Great job.
there should be a recumbent version also. if powered with electricity, and with some aerodynamic cockpit, it could compete with cars for in-city commuting
you are unbelievable perfect !
What's the advantage over a normal, two-wheeled cargo bike? The disadvantage, obviously: More moving parts, more prone to failure; and more weight.
Amazing. I hope will not expensive...
I'm sitting here with CAD software open and 3 bafang hub motors.
so

Bonjour où trouver ce tricycle ? Merci de bien vouloir me répondre.
Curious - does this require balancing like a bike?
Does this bike have torsion suspension ?
I will buy this. Please make it.
Nice! But There don't see suspensions, so going off-road is not going to be very confortable....
that is awesome
what type of wheel did you use for the rear tilting system?
Εξαιρετικά ευφυής κατασκευή και τεχνική υλοποίηση. Αν καταλαβαίνω σωστά η λειτουργικότητα του κεντρικού διαφορικού στον άξονα υποκαθίσταται από τα διπλά ελεύθερα ? (δηλαδή ο εσωτερικό τροχός στην στροφή θα έχει πάντα ροπή ενώ ο εξωτερικός θα μειώνει αναλογικά με την ακτίνα στροφής ? ) Όπως και να έχει θερμά συγχαρητήρια! η εφαρμογή σε recumbent υψηλής ταχύτητας θα είχε ακόμη περισσότερο ενδιαφέρον!!!
Καλά το κατάλαβες Δημήτρη! Όντως σε ένα recumbent που είναι δύσκολο ο χρήστης να σηκωθεί σε λακκούβες θα έχει μεγαλύτερη αξία η εφαρμογή του συστήματος. Το έχω στο πλάνο. Το σύστημα μετάδοσης με αυτό τον τρόπο βέβαια έχει κάποια σημαντικά αρνητικά αλλά σε γλυτώνει από επιπλέον μηχανικά μέρη.
Ευχαριστώ για το σχόλιο και την εκτίμηση!
From the looks of this design, it looks like this could be applied to a Recumbent trike?
Yes! It is possible!
@@WhyNotCycles Hi, I'm a big fan of electric bicycles, I fell in love with one in particular with a white inverty motor, because I saw it on your channel and the truth is, I'm building a similar one, I'd like to know about your bike if you kept the one in the video. ? You would sell it to me, it is the best thing I have seen, I would like to buy it or contact you pintosomauricio@gmail.com I live in Colombia a big hug I hope your answer thanks
Como funciona la suspensión?????
which is better the ride this one or the two wheel in the front, one in the back version ?
This one by far.
@@WhyNotCycles thanks for the response!
is it not strange that you can't see the actuall space requirements of the rear wheels with your eyes during the turn ?
Yes it is. The hardest fact is you have to count the upper side of the inside wheel due to tilting phenomenon during turn..
@@WhyNotCycles maybe you could put two lightweight carrying boxes in the front part on both sides which would be equivalent of the rear axle width so your eyes could verify the turning curve in advance for the rear parts.
@Maciej Jan Długosz I think it is stable because it's inclining. On the other hand, tadpole can also crash. badly. Like this:

can I buy this
Hello. Im working on a new improved design of my rear suspension tilting system and I think, by the end of the summer, a Kickstarter campaign will be launched.
Thank you
Wonderfull
#whynotcycles you may reduced the rear weights by going front wheel drive FWD, lean steering instead. Same leaning design on rear minus chains and drive system. Or you may do both FWD and RWD lean steering. Now I subscribed.
@Maciej Jan Długosz For real????
@Maciej Jan Długosz Oh wow so disappointed. I need a trike bad. Thanks for the heads up.
👍👍👍
This before in future
How to make brother
Plz tips
How much cost
Bos aku orang indonesia berapa harganya?
Ты крутой челаут...тотко двигатель нужен не на батарейках...вся эта электричесская дичь это маленький пробег и шесть часов зарядки...нужен бензин.. и будет Ок :)
kickstarter Τώρα!!!!!
Make it gas powered with like a 50 cc 2stroke/4stroke or maybe a small rotary wankel engine(yes it exists!) from a lawnmower , it will be a lot more fun for your ears and it will be probably cheaper and faster to refuel.
What has a small rotary engine? Smallest I've ever heard of was a largish 1970's road bike (Suzuki I think) anyhow, rotarys are as thirsty as 2 strokes and need more care to keep running. If there's a lawnmower with a 50cc motor, it's a scale model! Smallest I've seen starts above 150cc.

Shut up and take my money!
I have built 13 tilting trikes. here is the UA-cam video I recently posted. ua-cam.com/video/dAXDy5tCgy8/v-deo.html I like your presentation, but your ideas on suspension and steering are too related to no tilt vehicles. Tilting changes a lot. I work mostly on active tilt control that manual and auto levels the vehicle at low speed and stop so the vehicle can be enclosed. You do no have to prop the vehicle up at stop so you can do everything a car can with smaller footprint material and fuel usage all beings being equal. Contact me if you are interested in sharing insights.

when this bike turns the axel pivot point comes way to low you will hit a boulder a curb the deraileur even closer you slow way down when you come to roughness because it will bottom out and derail the chain .you have a lot more work if you want to carry weight any thing in all applications of transporting cargo does not lean . come on now the weight be all over the place. bike manufactures wont touch it because it has problems only the creator knows of your spinning counter wheel useless on hill climbs oh i didnt see any hill climbing you know and the people who buy this bike will still have to navigate terrain so that claim is false show it climbing anything something also allow others colleagues people who use bikes day in dayout decide if this design is superior under true conditions it will fail thats why manufactures wont touch it sorry i know a little something about bikes simplify when designing for average consumer trouble free easy to maintain is the key
how many times does this bikes chain come off your rear tires ....alot you slow way down on bumps and that chain is loose you dont pedal at this time because it comes off alot stop speeding up the film is the bike simply a down hill bike not one incline in any of your videos not one the terrain has already been selected and you have to navigate its course or bad things will happen some your claim is not true superior to what iknow all this because i did the same thing your arrogance angers me because i know and others need to
Have you seen the Mastretta MX3?
That is bad ass
