    Did anyone ever consider a SEMI Tadpole?

    I have this, perhaps crazy, idea to provide a little more stability (less twitchy steering) when a recumbent is expecting to have to ride slowly in a congested area.

    Replace the front wheel with an extended axle, perhaps 1 foot long. Put a wheel on each end of this axle. This would probably work best with 20" front, 26" rear SWB designs.

    Yes, in a small radius turn you would be putting a BIG load on the forks as one wheel did all the lifting. This is not meant for small radius turns.

    Ever see such a thing? Is it totally crazy?

    Interesting concept.

    It would add stability when taking off or at a stop, and I'd think definitely reduce the twitchy steering on a USS. However, the closeness of the wheels I think would defeat the two wheels when running down the road.

    It just seems they'd be to close together to do any good and possibly be a hinderance. Also.... talk about heel knock - it'd be brutal unless you moved the fork positioning too.
    Peace. It does not mean to be in a place where there is no noise, trouble or hard work. It means to be in the midst of those things and still be calm.

    Head tube angle would make your steering sorta crazy with a footlong axle in place of a front wheel, I think you'd really hafta lean to turn, or ride up on 2 wheels, kinda hard to visualize...

    I think someone has done it before. Maybe you could figure out how these guys did it?

    ya know, Chief, I heard the Italian version of the USPS, would that be the IPS, was going to use these as delivery vehicles to swabies that were listing.

    thanks, Don
