I have a real monster, a Howard Gem. Big TJD Wisconsin twin on it, crank start and heavier than a dead priest. Probably 30-40 years old and dead reliable.
Dad lives in town and had a huge garden, people always stop to look when he is using it. Unbelievably easy to control with one hand, and handlebars swivel to either side.
One of the few examples of British engineering I have ever liked.
