Very nice! where did you find this thing?

It's a clever gadget. But having made some stuff along those lines before, I can say with confidence it's an expensive, heavy, complicated, inconvenient way to do what a two wheeler does cheaply, simply, conveniently, and with minimal weight.
I'm sure it works better than the one I made, which has a solid front axle and thus steers like a tilting bakfiets. Which is to say, not very well.

Boy, that would actually make a pretty nice all in one system. How well would having dual hub motors work with the leaning? You could have the battery fit into the new second triangle. As well as the controller. You'd just have to run the throttle up to the steering wheel. Sell additional battery pack for the bikes original triangle. Could you even put a steering sensor that would slow down the inside wheel on a turn, and slightly speed up the outside wheel to make it turn easier? Your weight from the battery would be about as low as you could get it. Just a few thoughts. :wink:
If you guys were interested to have a leaning trike and are able to DIY frame work too,I'm planing to make a small package kit(not easy done components for DIYs :CNC axles with heat treatment,plate forming parts,knuckles sets- - )that only few hundred bucks one can have an easy work complete kit to transform a bike to leaning trike

Cool, this is pretty much the same system I built in my trike prototype for winter riding.
The background was added safety on icy roads. Which is accomplishes very well.
However it is always a compromise and it needs to be narrow enough to not be clumsy.
How wide is this front end?
What this system seem to lack are the steering spindle's rotation center projected to the tire contact area (or very close to it)
This means you get a lever that will affect the steering when you hit something with the wheel.

Yes there are some geometry compromise to make maximum profits of all,I saw your avatar on website before,why I didn't incline the kingpin is to get more tilt angleWheazel said:
If you want to reduce scrub,build your own wheel rim like a car ones,the scrub 78mm of bike is actually 70mm

I am doing a version 2 of the tiltbike for the coming winter, it will however have 4wheels to keep the trackcount in the snow down to 2.
Also easier to avoid obstacles with 2 tracks compared to 3. But everything is compromises left and right.
Good luck with the product!

You sound like you are new to electric hubmotors. Until you gain some experience, I suggest a direct drive hubmotor in the rear wheel with a sensorless controller, that would be the simplest and most reliable system for a beginner. Since this tricycle attachment appears to be for street use (instead of off-road mountain paths) You will be fine if you want to choose a smaller wheel, like a 20-inch. A 20-inch wheel will run cooler and more efficiently than a larger wheel, like a 26/29-inch.
If you like higher speeds, I think you would be happier with a higher voltage battery, like 48V, but...if you are just starting out and don't need very high speeds, a 36V battery will be much more affordable. I suggest buying the largest battery that you can afford. Doing this will allow each cell to run cooler and last many more months than if you put a strain on them.

Someone needs to fix some mudguards!
That quad has basically the same tilt setup I am planning for the winter quad build.
The main different thing I have done with the front compared to my trike, is separating the tilt and steering movements to different joints.
This gives me more tilt angle while still having an angled kingpin.
Your front end kit seem to use ball joints to give good tilt movement but less steering angle? Or do I misinterpret the pictures?
Not just ball joint,wondering if you ever saw the tricks before- oversized ball joint with spacers beside so you get enough angle to steer and tiltWheazel said:Someone needs to fix some mudguards!

A whole kit to make any bike into a leaning trike for a few hundred bucks , Yes , Yes !
How much would it cost in shipping from Taiwan to the U.S. ( California ) ?
How much does it weigh ?
Keep in mind that many of us have bikes that have front forks that are tapered, 1 1/8 inches top to 1. 5 inch bottom .
So
You would need to make kits for both kind of bikes, 1) for bikes with head tubes that are straight 1 1/8 inches
and 2 ) for bikes that have head tubes that are 1 1/8 top and 1.5 inch bottom
And/Or
An Adaptor that will allow the use of a straight 1 1/8 tube on your tilting front end, that will fit into a 1.5 inch bottom of head tube on a modern bicycle .

Count me interested too
Don't know the freight cost yetScooterMan101 said:
The 26" blue trike is 23.5kg now,the kit modified from motorbike kit still too heavy,fit for 5kw E bike is still ok;I'll lose it's weight later
The kit won't fit all bikes especially fiber frame

A gadget yes, but also nice for a cargo trike. Non leaning trikes are horrible when cornering. Sure there are great two wheeled cargo bikes, but the length of those cargo bikes makes them a bit slow and cumbersome to handle in urban settings, and in tight spaces or if you live in an apartment and use elevator to get up to the flat. Impossible to get a 3m cargo bike into an elevator. A short wheelbase trike is something else, the trike will fit inside elevator. Nice and easy to ride, easy to handle especially in tight places and the width will still let you ride between lanes when traffic is jammed. And on top of that you can carry cargo, pick up parcels or haul enough beer to last a party. Oh and leaning trikes are also insanely fun to ride. It feels like you are ignoring the laws of physics when the trike leans over.
