Roman Road Cycles is a small company based in Wales, somewhere a bit south of the middle, or more precisely, about half-way between Aberystwyth and Carmarthen. We make tricycles and tricycle conversions, both solos and tandems. Our trikes are different, as you can see in the picture below, in having 2 wheels at the front and one wheel at the back.
We also supply some components, principally hub gears and hub brakes, and we offer a custom wheelbuilding service. We can supply mail order to most places.

The picture below left is of a Newton Tandem trike. This is a
custom-built frame suitable for touring. On the right is a solo trike,
the C21. Designed in 2000, the C21 is a complete solo trike frame (not
a conversion) and is available both with touring equipment or for the
more sporting types."
