How about a cargo area that stays level as the trike leans.

You could use the open tube ends on the top A-arms as mounting points for a swaybar.

The PDF BOM file isn't opening the links correctly. Can you provide it in excel?

Can those clip style connectors handle 10A and not make a little unplanned fireworks inside the box ?

Can you make it fast charger?

PLEASE make an electric pedal assist version with suspension

thanks

can I place an order😅?

Keep the aluminum axles, but add internal threads for a 14 mm steel bolt. Or maybe a short piece of 14 mm BMX axle with 1 mm pitch threads. Thanks to your videos, I am thinking about using these hubs for a non-tilting delta trike.

After going to the trouble of building one, I'd hate to have it stolen. What do you suggest to do to prevent this? Theives carry cordless angle grinders these days.

Hi pedro, just an idea : if you redesign your trike, put your shock absorber on the lower arm, cut the front pipe between the plates, make something like a box for the front plates. Like that, the cargo can go until the front (or overlap the front ) of the trike..event reduce the trike lenght.

max and mellon have a similar design if you need ideas

the cable steering is clean, but a dealer that carries cable and rod style steering informed me that they preferred a steering rod because the cables stretch over time and felt more vague.. Love your build. I want to build something at some point, like an electric rikshaw.

A week link in a bicycle wheel is that it is made to be supported on both sides. Regardless of what material you use, I think the axle will bend over time. If not break.

Imagine a 4 wheel version with the cargo section at the back and wider wheels 🙂

Awesome design! Thank you for bringing us along on this journey. I have a couple of questions regarding the front assembly. What type of tubing did you use for the links? (size,wall etc..) And could you provide a link to the ball joints you used or provide information on how to source this "grade" of part?

I’m guessing having a material with a fatigue limit is necessary for those high stress parts like the axle. The load changes so much, I feel like it’s bound to break eventually with almost any thickness if it’s aluminium.

Adding Ackerman angle will stabilize your steering

I am not fully convinced. Doesn't the tilt angle depend on the velocity and loaded cargo's weight? If so, the steering and tilting should either be independent or the tilting must have an element that adapts to the speed and weight. Maybe it must even be an active one, but that's not a problem since it's an electric bike anyway.

I recommend to make the wheel axis of steel instead of aluminum, since a steel axis can be designed to withstand the fatigue effect, but not if we are talking about an axis made of aluminum.

Very nice indeed. Does it have enough tilt angle before the ball joints reach their limits of travel?

Hello everyone, I just created a new video with the newest version of the charging station: kzbin.info/www/bejne/oZ6Una2sjJmWsLcsi=P__f4EJCuyTOBvQZ. I decided to put EV Charging related stuff on a different channel from now on for consistency of the content. Cheers!

steel axles is the way to go

8:51 you experienced my job here haha, yeah 54 in for 54 out NEVER gets in without hammering and damage, even without welding. The CAD is smooth and perfect and (I learned it the hard way as a junior CAD) never ever applies in reality. At least 1 mm even 1,5 mm of gap when you want to position something 🙂 besides, I wish you good luck for the day you may want to put that part out to put something else in place ! That mentionned, great job !

Hi ! Thinking about buying or making a cargo myself What are the positive and negatove points of cable steering compared to "solid" steering with a rod or something ? Is it smoother or something like that ? Thank you in advance Great job !

Very cool, how about 4 wheel tilting ebike?

Exelente!

awesome design

Gracias.

GRACIAS,GRACIAS, GRACIAS!! El video mejor explicado y filmado que encontre., gracias ❤❤❤.

no, heat the outer tube, don't get larger tube

Loctite. I'm dying. Use loctite.

The early Audi TT’s had rose joints on the rear lateral links for the Quattro variant. 8 of them! They were known to seize eventually with road salt and water ingress. People eventually replaced them with bushings as it was only a very small amount of rotation. Such a cool project, congratulations.

Probably the best tilting trike build video you can ever find. Thanks so much

It’s a late comment but if these 3d parts can be casted in aluminum, and wheel epoxied in glass and carbon cloth they’ll hold up I’m sure.

🚴🏼🚴🏼🚴🏼🫡

Neat project. In other vehicles with 2 steering wheels the inner end points of the steering linkages are in alignment with the pivot point of the upper/lower arms and that's achieved by using a rack. It feels like the same would benefit you?

Lets hope the tadpole trike designed aptera has adopted some of your designs

Go with steel axles. But then you have a problem with steel + aluminum where the axle ties into the triangular part. So make both out of steel.

To fix point 1 just add a bend in the lower control arm. So that the ball joint can travel further

steel axles would be great except galvanic corrosion, I don´t know if there is space for coating to separate them from contact, so consider, btw. best trike I saw anyone made, because yours is tilting, I love it, enjoy it

Regarding axles, have a look at a video on my channel, "replacing the bearings on a 8freight cargo bike bootsowen" (search) the bike is a 2 wheel cargo bike with single sided axles front and rear. the axles are steel into aluminium and are 12mm tapering to 10mm, much smaller than yours. I only have one front wheel so the loading is effectively doubled in my bikes axle compared to yours. Regarding where your axle broke in service: where you go from one turned diameter to another in your axle design it is important to have a radius and not a sharp step in the turning, as stresses will tend to be much higher, but putting a radius in will lessen the point stresses in the material.

One feature of a bicycle is the ability to traverse an obstacle like a sidewalk stone by lifting the front wheel, swiftly (without descending from the bike - as well as driving down stairs). It seems to me a major drawback of cargo- and tricycle designs to loose that feature as sometimes obstacles can be overlooked (like a pothole filled with water in pouring rain conditions)...

You have to get other people to ride it because the more You ride it the better you get at riding it and the more difficult it might be for someone that never sat on it.

I think this would be a great Kickstarter project for tinkerers. You could provide backers with a more detailled build guide and the custom parts (e.g. CNC aluminum parts) and get a small profit for the time you invested into the development

Failure is the best part of anything you create and operate. What aluminum alloy did you utilize for the axles? The engineer in me is confident aluminum can be used with minimal challenges. The realist in me says move to steel, and spend the saved time modeling the geometry. I would still increase the diameter as much as is practical. I should have some free time this weekend. I'll download your drawing and see what kind of solutions I can produce.

Awesome project! I think you could make bent arms (U-shape) so the ball joints meet the knuckles at more open angle.

More brilliant work, this is starting to look super clean and I'm excited to start my own!

Fantastic to see the evolution. You certainly have more experience than me, however since a few failures I've developed a nagging fear of metal fatigue in aluminum. I'd probably want to consider steel. But, then we have the potential for galvanic corrosion. There's no way that joint won't have an electrical connection as well as electrolyte (road salt etc.). So I'd be interested in hearing what you think. I'm starting my builds with a bike trailer (non tilting 😂) but would like to someday build a recumbent trike ❤

Excellent work! Very cool design. I think that type of bike would be great for bike delivery especially in winter conditions.
