The ST2’s SYNO Drive motor is a brushless, direct-current motor located in the bike’s rear hub. Since the motor is fully integrated inside the hub, the only mechanical contact is between the industrial-quality ball bearings, resulting in an incredibly quiet, ultra-efficient, and virtually maintenance-free system.
If 35Nm of torque isn’t enough to put a smile on your face when you first put pressure on the ST2’s pedals, then its 500 Watts of power as you tackle hills or race to get to work on time, surely is. The ST2 provides pedelec assistance up to 45kmph, so you can save energy even above cruising speed. To handle all this power, the ST2 is equipped with front and rear thru-axles for increased rigidity and security.
