Hey Bruce, if you're still around, I was wondering if I could pick your brain about those axles you use on your fwd trikes. I'm trying to make a lightweight velocar/cyclecar and have been looking for something similar to what you've crafted.

Why?

A Velomobile Milan going back in time to 1985, would be faster than these !

It makes sence having front wheel drive because more wieght is on them then on the back wheel...

That front derailleur has quite the jump between gear rings

🥱🥱😴😴

Bhai agr koi samne lkde ya bans agya to sedha gand me ghusega ye khtre ki gadre he I don't like this

Hello David, Could you build a frame for me? Thanks, Giovanni

Your trail videos are awesome & informative about all of the local Florida trails. Where I live currently we only have a few trails with decent scenery, but nothing like what you have in Florida. You have me very excited about riding all of the bike trails when we move there. I've been roller skating (real quad roller skates not those blades) & biking now more often for a few years now. I also do HIIT training on my home elliptical machine & also have an outdoor elliptical bike to get into better shape (I've done 21 miles on our trails on that beast a few times). I want to get into better shape before we move to Orlando in the future. I'm retiring from my job in a few years & am moving to Orlando to work part-time at Disney. Could you tell me some really close places to Disney where we could move where I would not have to cross I-4 to get to work (we are having trouble narrowing down where to search for a new house)? Are there other trails in the Orlando area that you could highlight in the future ? Thanks again for everything that you do with your channel.

Any details of the Sinclair C5 race held in 1985? Would love to know more about this!

Would be interesting to see how the pivot point/shock in the middle effects control dynamics and ride at speed.

I've never seen anyone use a pin as a key. This doesn't seem to be a good idea.

What a great evolution since the S-327! I wonder though, why mechanical front brakes when hydraulics have so much better modulation, especially when running a dual set-up?

Nice project! And ... weight?

Are there CAD files available?

Wonderful design.

Wonderful...

Bad picture quality

Blowing through stop signs. What as pro

Can wait to see it test film

Inspiration good to me sir #DavidBruce Thanks a lot

Very Cool!

I like you video and you created... #DavidBruce imagination for me for make one like yo do. Can you send me detail of you bike front wheel.. please sir

What design work and what quality of construction !!!

HoLa me gusta mucho lo que hiciste, me gustaría hacer lo mismo tienes planos que me los compartas ?

You have done some impressive engineering here and my hat goes off to you. That being said, there are so many possible ware and tare points of failure with so many store-bought parts that have been modified service would inevitably become a nightmare. If this trike is only for you're sole use I see no problem and say well done but if you intend on selling them I truly would have reservations. Its a beautiful bike none the less, well done. I hope over the years you have realized and addressed the concerns I have raised here as its an interesting design. There is a reason multi-wheeled front-wheel-drive anything has been a pain in the azz and that is because if its complexity vs rear-wheel drive. I'm in no way saying the rear-wheel-drive is better just it is simple with few points of failure. If you can produce quality standardized replacement parts to customers without delay I can foresee success but if not I foresee a lot of aggravated customers in your future.

Thanks for showing the CV shell! I want to build a front wheel drive quad bike / velomobil and been trying to figure out how a CV shaft works. Yours is really nice and compact. Beautiful machined. I'm hoping to find an affordable set of differential and CV shaft light enough for a quad bike. What I don't understand is that you have a CV joint (Rzeppa? Weiss?) on one side and a cardan joint on the other side. From what (little) I understand this wouldn't lead to a constant velocity shaft. Or you'd need a double cardan joint on the wheel side.

Where you can find a dealer for or you have to order online 😍

David, update please.

I know this video is 6 years old but, dbtrikes.com is no more. I wonder what happened?

Look Mom no hands street legal got to love it spring is coming

Yup!!!@ some took the time!!!

And finally, where did you get the green and yellow polyurethane springs/dampers from again? And also the metal pieces that press against them?

Believe me I'm impressed, but can you elaborate a little, please, on why you went through all this effort? I can tell that you really wanted to see this to completion, but can you tell us more about what your motivations were? I'm just gobsmacked here.

Did you cook up that suspension mechanism yourself, or did that come from elsewhere? If elsewhere, I'd sure appreciate knowing where that was.

Hi David do you make the trike its really well built if you do make the trike I just want to ask if you can do ships it to Canada and how much it is thank you

Hi David Bruce, your trike is great! i am planning to build a 4 wheeler in brazil myself. my traction will be rear. how did you do or find this differential axle and the transmission bars to the wheel? could you give me a hint? sorry for english and translation. thanks!

That is an awesome trike. I wonder, what are the advantages of forward wheel drive compared to a rear wheel drive setup? I suspect that you can't climb steep hills with this setup (while climbing hills 60% of trike + rider weight will be distributed at the rear wheel). So would it make sense to go 3WD (three wheel drive)?

This is excellent. I hadn't heard of this event before, and I love recumbents, and faired bikes. Great upload, cheers!

where can i get that mechanism

Very nice! Amazing quality!-Where did you get such axels for front drive and differential? Thanks in advance!

Awd 🤔

nice engineering !

Hi David, constructing a traveltrike myself and am searching for a nice smal cv-joint, like you made in this video. You don´t have one lying around to sell me or found an industrial equivalent?

Great looking machine but where is it? The website you list is not working.

As of 2019, are any of these front drive differentials available for sale? Is anyone producing them?

Can I have this bike please
