Rotec Powered Bikes

Back in 1999 I dreamed up a radial engined trike just for fun (Cadbike 3),
never expecting anything like it to ever be really built but:

I have been getting a lot of Email about these 2 bikes recently, both are powered by an
Australian built radial engine, built by Rotec (http://www.rotecradialengines.com)

The bike in the lower right picture is built by JRL Cycles (http://www.jrlcycles.com),
the other one was built by Jesse James (http://www.westcoastchoppers.com)
