Lloyd Wilcox shows his mechanical skills in building a twin engine motorbike in 1967.....

Lloyd Wilcox of Oteramika Road, Invercargill built one of the most unusual bikes that had not been seen in New Zealand in 1967.  Just by reading "hot rod" magazines he managed to combine two engines into a Triumph frame. 
​

Lloyd along with his friends spend nearly 50 hours on the machine and they were hoping to reach speeds of in excess of 110 m.p.h.
His thinking is that the two 350 c.c. Matchless engines will pull the same weight faster and at higher revs.  This certainly was a new era and was a credit to his mechanical skills.  He was wanting to use the machine for quarter-mile sprints . 
Costing only 15 pounds to build shows how much time he had spent getting parts.
The petrol tank holds about half a gallon of fuel, which means it would take the bike three to four miles.
This ingenuius proves that Southlanders can do anything.
