Hendrick’s Rolls Out Victorian Penny Farthing (Big Wheel) Exercise Bike

The gin maker’s newest offering, ‘Hendrick’s High Wheel’ is a stationary ‘penny farthing’ bicycle. (For readers who are not up-to-date on cycling history, the penny farthing was an early cycle popular in 1870’s; you might recognize them as those old school cycles with one giant wheel and one small one.) The Hendrick’s version is intended to be a throwback, low-tech response to the likes of the Peloton.
