A big and bad attitude to match the wine that shares its name, the Barolo is the first in the line of exciting things to come at Masi. A Fazua drive unit and full carbon gravel frame and fork make for a bike that is as happy on a lonely dirt road as it is mixing it up in a Saturday morning group ride. The Fazua evation drive system is the lightest and most compact mid-mounted system, having a non-motorized appearance. The ability to replace the motor and battery with a cover, coupled with the low-friction feel make the Barolo easily converted to a standard, non-assist bicycle. Whether it is going further faster, or just keeping up with stronger riders, the Barolo will bolster everything you love about riding.
