TTW - Tilting Three Wheelers

Human Powered TTWs

last updated 6/26/2005

A partial survey of human-powered tilting trikes... (a more complete list is below)

LE CRAFT, early on Andrew Phillips' L.E. C.R.A.F.T.

This picture, from Feb. 2000, shows the trike in development. Note the supports for the canopy for all-weather touring.

1F3T. I finally have got around to putting up information about this beautiful home-built trike. The "L.E. C.R.A.F.T." (Leg Energized Commuter Recumbent Aero Faired Trike) is "a fully enclosed, three wheel, Human Powered Vehicle or, H.P.V., also referred to as a Velocar." Andrew's plan is to make a journey down the West Coast, across the country, and partway up the East Coast... starting in May 2000.

Go visit Andrew's page, and help him on his TOUR! He's welcoming all interest, from good wishes to suitcases full of cash.

2F3T. A very sophisticated, yet simple, TTW HPV. Wayne SooHoo is licensing this very interesting technology. Any interest? He's Give him a shout. You can also read more about Wayne's bike at this page, for a complete reprint of a news article about his speedy tilter. Wayne also has a powered version, also visible there.

Frank Bokhorst Frank Bokhorst's Recumbent TTW HPV, The Lean Steering Trike.

2F3T. In Mr. Bokhorst's own words: "The advantage of lean steering in the case of a trike is (hopefully) that there will be less tendency to flip over during tight cornering than is the case for a conventional trike that remains upright. This tendency can be countered by a low center of gravity and wide track. However, the present design has a narrow track, so it can pass through a normal doorway."

2F3T and others. This page has a range of home-built HPVs, some of which are tilters, but all of which are good looking to anyone with DIY compulsion.

Derek Round, & Co., Gravity Racer

Derek Round built this as a school project (with some partners, I think). Before the race, he wrote..

Its taken a bit of time, but its finished at last, and we've entered it for the UK National Red Bull Soapbox Racer Competition this Sunday!
Wish us luck?

And the caption for the second pic, a few days later:

Just thought you'd like to see a picture of our Soapbox racer, on the downhill course, just before we crashed(ouch!).

Well done, lads!

Bram Smit, Holland, tilting recumbent

Cool-looking guy on a cool-looking bike! Bram wrote:

Max....I tried to build a tilting recumbent trike as simple as possible. It corners like hell. Here I send You some pics.
greetings from Holland

I think he's got it!

He added later: 

The latest version of the trike has an vertical lock-out. So if I enter a traffic light, I stay in the upright position and I can keep my pedals clicked on .

Nice improvement.

He added this detail pic later:


It's a pleasure to make your acquaintance, Bram! Good luck with this cool machine.

A gateway to all kinds of good people-powered stuff: it's the International Human Powered Vehicle Association. Not just bikes, but boats and other vehicles, too. These are the champions of, as they wittily ascribe to one designer, "Muscle Cars."
