Smart Motor Ristretto 303FS
MOTOR CORE & ROTOR
The Ristretto 303FS comes with the latest X1 PRO Gen 2 motors built with new tooling equipment and QC procedures.
Capable of handling >12krpm >6kW peak reliably.
Hall sensor wire is upgraded with waterproof connectors.
HIGH QUALITY COMPONENTS
There are multiple components upgrades with the best materials in the industry apart from the controller and motor. To follow a concept born in the Renaissance where Leonardo da Vinci told us that art and science are disciplines that need to walk alongside.
To create the Ristretto 303 Full Suspension, we need it to make an upgrade in our performance, to put this together requires creativity, patience and passion that we shared with CYC motors one of the most competent partners in the electric motor sector.
The gearbox is refined and with the new gear machining profile, and the gearbox noise is reduced by 50% as a result.
The electronics and sensors are built in so there is no external part that is easy to be damaged.
Increase of teeth number such that the engagement when pedalling is much faster and more direct.
Sprocket at the output shaft is machined with hardened steel instead of stainless steel, which handles 5kW or more extreme power.
TORQUE SENSOR BOTTOM BRACKET AND CRANKSET
The crank arms are made with CNC aluminum lightweight crank arms.
Meanwhile the torque sensor is equipped such that both the torque and cadence signal are collected and processed by the controller to provide natural feeling of pedal assist.
The Torque sensor and controller firmware is tested extensively in the trails and we are proud to achieve comparable response and feeling as the Euro- spec (e.g. Brose and Bosch etc.) EMTB in the low power legal mode.
