Ai OFFSET CHAINRING
A custom Ai (Asymmetric Integration) chainring moves the chainline outboard by 6mm, creating space for ultra short chainstays with plenty of tire clearance, and lining up perfectly with the extra-wide, extra-stiff 157mm rear hub.
To protect the motor and battery from damage, Moterras feature the BatStrap rubber battery cover and a burly, trials-style skid plate.
Si MOTOR MOUNT
This proprietary Cannondale motor mount positions the Bosch drive unit in the best possible position. It allows ultra short chainstays and aligns the pivot so that suspension action is unaffected by motor and pedal torque, no pulleys or linkages needed!
TORSION BOX DOWNTUBE
To maximize frame stiffness and create ideal battery placement, a rigid battery chamber is welded to the underside of a fully enclosed, hydroformed downtube. The resulting "torsion box" structure is massively stiffer than "open" downtube designs, and carries the battery as low and central as possible for great handling and agility.
