DBT4 FWD Recumbent Trike Build Assembly Series!

A brand new 2013 build and assembly video! We do a dry fit on the new DBT4 FWD Trike. This short video shows some assembly of the internal differential and provides a brief look on the new front wheel drive recumbent design. We raced the new design prototype at the 2013 HPV Race America event in February 2013 and have been working on new "production" units this year.
We've been getting a lot of subscribers lately and this new video should build some excitement of what's to come.

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.

a lot of interest in this diff and a price and no mention of sale or when

[@bobcummings154]

lovely engineeering

[@scbvideoboy]

Not at this time, the current diff is all custom made and expensive. Later on we might try to modify the frame shell to accept a store inexpensive bought diff, however they have proprietary splines and shafts and that would mean a rework of our drive line.

ok thanks for your anser

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?

[@chriscraft999]

Do you still make trikes. I would love to buy one

[@yasser33311]

hello, i am interesting in do some think similar do you self the differential ??

[@guillembriones7907]

hello, i am iteresting in do some think similar do you self the diferencial??

[@thelastwheel]

What is the theory behind choosing FWD/FWS? Does the diff add more weight than the reduced chain length subtracts? Would it be possible to incorporate a single disc somewhere on the axle rather than have two, one for each front wheel? Lastly, did you ever consider a shaft driven system, similar to a car-you already have cogs grinding away, perhaps even a planetary gear system could be possible.

[@thelastwheel]

My mechanics is completely naive, but I feel a reverse gear may be possible as well.

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

How much are you selling these recumbent trike for....
