MOZA Wheelbases — Latest Versions Comparison
MOZA Ultra Series & Latest Versions
Both Ultra models launched in late 2025, replacing the R21 V2 and the top end of the lineup. Key upgrades over previous generations: switching from servo motors to flat-wire zero-cogging motors (26% higher torque density at the same volume), the new NexGen Force U1 algorithm replacing 4.0, built-in RGB strips for telemetry, and on the R25 Ultra — a built-in torque sensor with 2 kHz sampling rate.
