It’s actually upside down so the wheels are turning in the correct direction at each tilt. :-)

My tadpole trike is my personal creation so isn't for sale and I believe the Trivet still isn't in production facebook.com/profile.php?id=100043104670710

Hi Jose, I designed and made this trike myself so I’m afraid it is not for sale.

Sorry, all the plans are in my head. :-)

Hi Rob, this trike was designed from the ground up around the electric hub motor meaning that I built it stronger to handle the higher speeds enabled by that E-assist so the extra weight isn't a problem. What the tilting has allowed is for the trike to be taller with a higher seating position to see over the hoods of cars around me while still maintaining a nice narrow track width of only 80cm allowing me to fit through the bollards of pretty much any bike path thanks to the tilting which saves me from over-balancing when cornering at speed. Here is a video of the trike in action where you see it leaning into curves at speed. th-cam.com/video/vZ6-_mKERUg/w-d-xo.html I've frankly been amazed how well it works. It's not perfect yet as there are a few rough edges and some design changes I plan to make to the front suspension geometry to allow me to tilt to a greater angle, but it is my reliable regular commuter vehicle that has proved itself over these last few years. Here one of my latest videos that shows the lightweight roll-cage, windscreens and roof that I've now fitted to it: th-cam.com/video/WYAoAAKhMu0/w-d-xo.html

@@martinhill9011 Hi, thanks for getting back to me, I was leaving the electric motor out of my thinking. Cool design.

Sorry Gesualdi, this is just my personal transportation so not for sale.

@@andrewfranklin4429 Ok. Fiquei encantado pelo veículo, pois além de inclinar as rodas, tem amortecedor achei‐o muito legal e interessante. Espero que você curta bastante e aproveite o seu veículo. Valeu, abraços. 👍🏻👍🏻👍🏻👍🏻

@@gesualdi1989 No problems Gesualdi, thanks for your encouraging words!

@@martinhill9011 Encontrei um rapaz que falou que talvez consiga fazer uma parecida. 😀 Obrigado pela atenção, felicidades e tudo de bom. 👍🏻 Tchau. 🙌🏻

@@gesualdi1989 Good luck!

I live in Perth, Western Australia

If you look at the other videos on my TH-cam channel you will see much more detail.

I've got a car and a nice 4WD already, why would I want any more? This hybrid (human-EV) tilting trike charges free from my rooftop solar and gets me to work as fast as my car thanks to shortcuts and avoiding traffic and gives me a good workout if I want to pedal. What's not to like? :-)

It’s only a top gear reference, no harm meant

@@reginald8228 yes it did sound a bit Jeremy Clarkson. :-) no offence taken. :-D

The whole vehicle is made of aircraft grade lightweight cromoly steel tubing so it’s actually not too heavy.

Sorry Jose, I’m afraid this trike is my own design and construction and is not for sale.

Again, sorry Jose, this trike is my own design and construction and is not for sale.

Sorry Jose, this trike is not for sale or commercially available as it is my private project. Thanks for the interest anyway! :-)

Hi Antonis, yes, this iteration of the steering geometry suffered from quite a few problems! I significantly re-engineered the steering linkages to eliminate the possibility of the control arms hyper-extending as you can see in this video: th-cam.com/video/koADanl4-vo/w-d-xo.html . With regards the rod ends, in this later iteration, they actually have two axis of movement so that the steering angle range is not compromised by having such a large range of leaning angles. If you look closely at the rod ends, you will see that they freely rotated within the tubes that the rod ends are mounted in. Hope that makes sense.

Hi Randall, I designed, fabricated and welded the roll cage out of lightweight, thin wall cromoly steel tubing myself. I'm afraid the plans are all in my head as with everything else on my trike! I have more ideas for finishing off the roof and body panels front and rear as well.

@@martinhill9011 The big additional features i would like to see: turn signals, good lights, a horn.I can live w/o the windsheld, but if you have it, a wiper might be nice. Prtdonslly ig i hsbr onr og these, i would like to be belted in. I think there really is a market for somethign like this. The only commercial product i have seen that has a good roll cage is this one, which is a racing trike with no suspension out of austrailia. I think it is $5400. It has a seat belt and straps folks in. www.bentrideronline.com/messageboard/showthread.php?t=138369&page=2

@@randallburns5704 In my case, I need to re-hook the turn signals, lights and horn back up that you can see in this earlier iteration: th-cam.com/video/wLmHCX4uZFY/w-d-xo.html I do also have a retractable seatbelt ready for installation, but haven't got around to installing it yet. I do also have some ideas for a wiper, but we have so little rain here in Perth that it hasn't been much of a priority yet. :-)

Actually the wheels do in fact stay parallel at full tilt as you can see in this later video: th-cam.com/video/koADanl4-vo/w-d-xo.html

Hi Peter, this recording is probably the best way of showing the mechanism in action: th-cam.com/video/koADanl4-vo/w-d-xo.html

@@martinhill9011 Martin, what are the spacings of the top and bottom wishbones at the frame end and the wheel end? And how wide apart your wheels? What distance is between wishbones vertically at both ends tremlett@emailaccount.com if you want to continue in private

Not for sale sorry emdr, it's just a personal project of mine.

Hi Orlanda, this is the front suspension of my recumbent trike. More videos here: th-cam.com/channels/y5hIJH6TQ5sob3XYsXMlAw.html

Yes, if you check out my later videos, you’ll see I fixed that issue with better chain routing and chain tubes making for a much quieter, more efficient drive train. :-)

I did indeed calculate Ackermann Compensation geometry for the steering tie rods though it is a bit difficult to see with the kingpin castor angles making it difficult to spot in the video. Also, when tilting, the Ackermann compensation gets less accurate at tighter steering angles. (although at higher speeds that result in greater tilt angles, the trike tends to rely more on castor steering and longer radii of turns meaning Ackermann is not as big a problem as I thought it would be)

@@martinhill9011 Thank you !! Very fast response! I understand, I was doubting how important it is on this type of trike. I have a project and I needed your opinion. Even in the distance, you help inspire us.

Unfortunately the plans are all in my head. When I finally get around to drawing them up, I will post them. Sorry.

Please when you will do the plans , share . Have a great day

Thanks to the tilting front suspension, there is a good 30cm (12") wheel travel on each of the front wheels individually. If both wheels hit a bump simultaneously, wheel travel is about 10cm (4"). Wheel travel on the rear is about 15cm (6").

I added a 48v - 12v DC-DC power converter and drive the flag, indicators, brake lights and headlights off that. Works quite well. Similar model to this: www.ebay.com/itm/Power-Converter-DC-DC-12V-to-48V-3A-144W-Boost-Step-Up-Voltage-Regulator-Module/333010479049

Hi Frankie, are you referring to the steering kingpins? If so, if you look closely, you'll see the kingpins are those black cylinders with silver tops between the outer suspension tie rod ends that are angled outwards and downwards which do in fact intersect the centres of each tyre's contact patch. This means the trike doesn't suffer any bump steer or brake steer and is actually very easy to control by tilt steering thanks to the castor-angle of each kingpin.

@@martinhill9011 I meant the suspension a-arms. Look at the way Steintrikes does the same thing except their upper a-arms are shorter and end right above the kingpin axis. :)

​@@FlankyFrankie Unfortunately that doesn't work for tilting suspension geometries. The A-Arms have to be equal length and parallel to each other for the wheels to stay parallel to each other (and the body of the vehicle) when tilted. Not to say my geometry is perfect though - Sometime in the future I plan to replace the front wheels with dished wheels that would allow me to mount the kingpins vertically within the wheels to better maintain the correct Ackerman compensation angles at extreme tilt. I'll also be mounting the inner suspension pivots on the centre-line of the vehicle to maintain the same wheel-track width even at extreme tilt and to reduce the acute angles of the steering tie-rods at extreme tilt angles. All of these changes are pretty necessary if I'm going to be able to increase my maximum tilt angle from the current 30° to closer to 45°.

@@martinhill9011 Fair point :)

Indeed! Half the problem was that my trike was quite noisey back then. This footage was from before I oiled and properly isolated the suspension pivots and the chain was rubbing against a guide close to the camera. Even then the noise was not as obvious from the rider's position and is much better now. :-) Some manufacturers use double-wishbone suspension, notably Stein Trikes and a few others, but it can be heavy hence some of the alternatives like ICE trike's ingenious compact front suspension elements.
