From a end-use perspective, the key difference is the extra 5Nm.
We design each wheelbase around the motor, selecting components & developing firmware to most efficiently deliver a given level of performance for any attainable torque level.
This approach means the visual difference is limited to a larger control box for the SW25 (264mm x 246mm x 127mm) compared to the
SW20 V3 (131mm vs 246mm x 127mm).
