The Pathfinder ST is driven by a 350 watt brushless motor, which is capable of momentarily delivering as much as 700 watts of power, allowing for quick take-offs and instant acceleration. With the power off, the Pathfinder ST will ride like a regular bike, no resistance noticed. Its fixed derailleur-less drivetrain has a constant chain tension that makes for smooth a quiet pedalling. The internal Shimano Nexus rear hub provides 7-speeds that give you the pedalling cadence you need to get some exercise, or giver her a boost on starts and steeps.
Important note : The Black version has a townie handlebar that is less upright than the others.
