Thanks Tinny for your great videos on Ackerman's law,trike steering ,and axle building -they were a big help in my pipe trike and my current 2 year build coming soon
Wow Tinny, just what I asked to see and more. This video is fantastic! Thank you, thank you, thank you. I'm grateful I didn't try to build one without seeing this first. I didn't realize there was so much to setting up the front end accurately. I'm definitely looking forward to the more detailed pedal axle video.
You have inspired me to build a road bike within a year. I am looking at the tube sets and lugs at Nova Cycle Supply, they sell bike tubes and other bike building supplies for the hobby builder. Now I just need to learn how to braze and weld. Good luck with the build.
Great vid, I'll see if I can post my recumbent. I used a bit of a diffenrent set up but I like the way your's looks. Great info, I will use some of your improvements if I build another one in the future. Did some research but didn't come across your design until after my build was through.
Thank you so much for sharing these important information with us. Its so helpful to know all that. Id like to build such a trike because I dont have 5000Euro to buy a new one and even if i had, iwould never spend that much on metal with some wheels on it. Thank you sir, greets from Germany.
This is the third time I watched Tinny explain recumbent trike steering. Let's see ctr. pt. steering, camber, Ackerman steering, and toe in. I think I got it.
Thanks for the tips. I really needed to clear those angles up before building my first trike. Now I know just what to do ! thank you ! But what are pedal axles ? Confused on that as I am new to this !
Absolutely brilliant video, thanks for the clear and simple explanation. That all makes sense now. Did you ever get to make a video for the front axles?
am building one this week but am making it electric. that is a slick design. i am brazing. dont have welder. u answered a ton of my questions for front end. thanks. i want to sure bout the steering assembly. into autocad it goes :)
Thanks for the video about steering geometry. Your explanation of Ackerman steering was very clear. Incidentally one thing you did neglect to mention was camber, although to be fair almost every trike I've seen has zero camber. I built a recumbent trike about two years ago. Like yours it uses pedal arms for the front wheel axles. The wheels have done more than 4000 km with no problem. I set mine to zero toe-in. Maybe the small amount of toe-in you use is peculiar to the design of your trike.
Easiest front axle/wheel is wheelchair wheels- if you can scrounge the quick detatch ones all the better. Most are 24" I've seen but got a 20" pair today at the scrapyard. Only problem is no brakes on them. Maybe the wheelchair axles fit disc brake hubs- will look into it.
Very informative. Thanks. Perhaps as a suggestion please consider triangulating the load on the lower 90° portion of the frame that connects to the front wheels.
The line from center of the rear wheel to the tilted Kingpin axis can vary depending on where the line ends along the Kingpin axis. Where should the line end on the tilted Kingpin axis to achieve Ackermann compensation ?
Hi Please correct me if I'm wrong... But I think it is "a line from the center of the backwheel axel...", not "a line from the front of the backtire..." !? Happy building. Kind regards
awesome vid . . lot's of great info - thank you . . i'm concerned about the two small pieces of square tubing on either side - where they are joined to the 'head tubes' for each front wheel - and how you cut them out so precisely, what with such specific degrees of angle needed, going in TWO differing directions at the same time? damn tin, that doesn't look easy - doing this well is what separates the men from the boys, since the better they are cut, the higher quality the welds will be . . .
This is very common in DIY and also factory built Trikes. The problem stems from steering geometry. You can increase the caster and get rid of it but will then not handle well when turning at low speed.
I need some help mate sorting out my steering system mate am failing please help me out I've built one from old bikes and the steering is falling on me pal I need serious help

Would like to contact you and see if u build them to sell very interested in speaking with u I have been working on one but turning out terrible!!!!!😡😠 do have a email so I could send
@cdltpx Cool vid. I wish I could setup one that would be electric with a solar panel on it. Sort of like this but with a solar panel maybe mounted over the rear wheel and basket. watch?v=LpZM53VTWxg

Thanks Tinny, this is great info! Very inspiring to see what can be done with some junk parts and a LOT of ingenuity!

Great information about the steering geometry. Thanks for posting!

Thanks for explaining the geometry. Good stuff Tinny.
My you are a clever chap. Great tips. Nice work :)
best explanation on ackerman pertaining to trikes! thanks!
Very Important information. Thank you!!

Very informative , Thanks .
Very interesting, I can't wait to see how the body for it turns out.
oh, and i hope we're gonna do some backpacking before the summer is over . . .

Hey where do you get your tie rods from??
The line from center of the rear wheel to the tilted Kingpin axis can vary depending on where the line ends along the Kingpin axis. Where should the line end on the tilted Kingpin axis to achieve Ackermann compensation ?
chuacl20 Good question ---the formula i used did not address this situation so i just went half way down the king pin. It works well.
Hi
Please correct me if I'm wrong...
But I think it is "a line from the center of the backwheel axel...", not "a line from the front of the backtire..." !?
Happy building. Kind regards
No suspension? U ever think bout doing that on nxt build?
Can toe in effect pedal steer?
One could hang the tires from the ceiling to get the tire level before marrying to the frame for final weld.

I've built a homemade recumbent and when driving fast I get a speed wobble , what's causing this?
This is very common in DIY and also factory built Trikes. The problem stems from steering geometry. You can increase the caster and get rid of it but will then not handle well when turning at low speed.
What about that rod going across at leg level??
@cdltpx post a link to that. WOW I would look.
O frame não ficou fino para peso de adulto?
I need some help mate sorting out my steering system mate am failing please help me out I've built one from old bikes and the steering is falling on me pal I need serious help
where did you find your chair,,i have looked everywhere thank you

That is a trike not a bike. A bike has two wheels. A trike has 3 wheels. I am always amazed that people call a trike a bike.
But a bike is a bike and a trike is a trike.
