From The Electric Garage. In 1974 Mike Corbin (from Corbin Seats & m0re) set the Electric Motorcycle Land Speed Record at Bonneville with “Quicksilver”, a bike that, in 1972 set the previous Land Speed Record running lead/acid batteries.
The 1974 record of 165.397MPH stood for over 30 years. ‘Quicksilver” was running silver-zinc batteries, thus the name. The bike was the first electric vehicle raced with battery technology beyond simple lead/acid.
That year silver zinc batteries represented a 8x “more available power” advantage over lead/acid batteries. Silver-zinc is a well known chemistry that has been used in space and still in use today.
