Pilot and YouTuber Sam Barker has a passion for engineering projects. This project combines the classic Penny-farthing bike with a 3kw hub motor, Sam manages to hit around 25mph, but the bike is a little unstable, he hopes to build his own more ridged frame in the future and push the speed up to 40-50mph. At those speeds he could set a world record for the fastest speed on a Penny-farthing bike.
