On my way back from Central Otago I stopped once again in Oamaru and the Cycle Works had acquired from their Steampunk friends a recumbant tricycle that looks like it is steam engine assisted.
As a rusty old recumbant it rode quite comfortably, but alas all that copper tubing is only for show.
So has anyone out there got a steam assisted bike or trike in working order?
And has anyone made a full size penny farthing with electric assist? (Kind of steampunk in reverse.) And I don’t mean one of those mini penny farthing contraptions like a Yike Bike.
