3 wheeled tandems...

I am looking for a tandem to take myself and my 22 year old son out. My son is 6 ft tall and has special needs.


Really struggling to find a decent tandem. Either they are 4k or totally special needs adapted.


Any help or advice....links to sites.


Cheers guys....

If you are looking for something that doesn't weigh a ton and is useful for riding more than just a few miles then you will only find them in that price range. The best one is probably the Australian made Greenspeed. I test rode a tandem Greenspeed at the Midwest Recumbent Rally in Wisconsin. It will last a lifetime. I own a single Greenspeed GTO that has many thousands of miles on it and is still as useful today as the day I bought it (used). You might ask the moderator to move this thread to the Recumbent section where more people who own such things post.

There are conversion Forks that let you put 2 steered wheels in front,

and there are at a higher cost tad pole recumbent trikes..
the Greenspeed, from Australia , was mentioned


the drive train of a single rear wheel in the center, function better, most rear trikes just drive the right rear wheel..


a counterpoint tandem has a recumbent front seat, and a regular bike saddle.. so you can talk to each other ..

but a 3 wheel you are getting into one off custom prices...

Have you seen or tried the ELF from Organic Transit (2 seats in front of each other.
or the Mo From Elvovelo? 2 seats wide by side.

Those look cool, but a bit expensive.

There are also a few pure recumbent tandems (2-wheel). I think most are front-steer, but they could potentially also be modified for rear-steer if one desired.

They might be able to be modified to a trike drive, but I'd probably move more towards a quad than a trike.

There are also a number of side-by-side quads that come up for sale regularly on Craigslist.... I think.

Oh, it looks like Utah Trikes is also building a custom recumbent tadpole tandem. Whew, those look LONG.



Utah Trikes - UTCustom Tandem II

It looks like they can do quite a bit of customization to their trikes, including hand powered. Front or rear steer?

Just saying, the o.p. did not specifically mention a recumbent tandem. The British in particular are fond of using adapter rear ends to convert tandems (regular tandems) and single bikes to a tricycle configuration.

Riding upright cargo trike- my experience is, 3 wheels adds stability when stopped, costs you stability when moving- so, for 6-8 mph, upright trikes are okay, for faster stick with 2 wheels or something with lower center of gravity, ie, recumbent.
Worksman products are not too likely to be found overseas, but, for reference:

https://www.worksmancycles.com/tt.html
Note that Worksman typically makes heavy industrial bikes, so they are generally low-tech, heavy, not suited to very hilly terrain.

The tandem and side-by-side trikes look interesting. But, I suppose it depends on what the OP's goals are. Tooling along the local bike trails, or making tracks across the country.

I've thought about building a cargo trike primarily because of hills. I still have to think about the design a bit, but it is easy to get to the point with my cargo bike that I just can't get low enough gears to get over the couple of hills to get home, and my own driveway can be impossible without motorized assistance.

And the trike should help with slow speed stability and stop & go riding on hills in particular.

That brings up the other point. So far with my recumbent trike, experiments seem to indicate that it is slower and less powerful than an upright. I still need to practice more, but I have a feeling that I'll never get to full power with it. Thus... for cargo, upright is likely the way to go.

a 'Counter point' front recumbent , rear upright.. would lend itself to a steered 2 front wheels , and a single rear drive wheel

tandem trike design not being 10 feet long..
