Can you grind whilst riding along?

No. There is a clutch mechanism that allows the pedal-drive to be switched from powering the front wheels (ride mode) to powering the grinder and water pump (coffee mode). You cannot do both at the same time for good reason! At the core of Velopresso is the goal of the highest quality ‘made-on-demand’ coffee. In terms of freshness this means the shortest possible time between grinding and pulling the shot, so grinding should really only ever be done immediately prior to pulling a shot….no pre-grinding, no stockpiling of grinds, just grind and pull, bespoke coffee. Besides, riding a bike in the city (and even moreso a state-of-the-art espresso trike) and making high quality espresso coffee both need and benefit from your fullest attention!
