Description

The Cannondale Synapse Neo Allroad 2 is a carbon electric road and gravel bike with a Bosch Performance Line Sprint mid-drive, which Cannondale's page rates at 55 Nm, and an integrated 400 Wh Bosch Compact PowerTube battery.

It has a rigid carbon fork, Shimano GRX hydraulic disc brakes on 160 mm rotors, tubeless-ready 700 x 40c Vittoria Terreno Dry tires and a Shimano GRX 2 x 12 drivetrain with flared drop bars. A Bosch Kiox 300 colour display pairs with the Bosch app, which adds a free motor lock.

Pedal assist runs to 28 mph and there is no throttle. Lights, fenders and a rack are not fitted, and the frame takes a kickstand. Cannondale publishes no weight and no range figure for it.
