Base on paper specification that say TICO has max speed = 6000 rpm.
But I don’t believe it and use 5000 to calculate expected speed instead. (also include speed@6000rpm as theoretically limitation)
For roughly reference for various gear ratio, expected speed (@5000) and speed limitation(@6000rpm).
In case of gear ratio: 1:12, max speed will be ~40km/h and cannot exceed 47km/h ß Cario’s transaxle is 1:12.3 which should not be able to reach 45 km/h
In case of gear ratio: 1:10, max speed will be ~45km/h and cannot exceed 56km/h
In case of gear ratio: 1:9, max speed will be ~50km/h and cannot exceed 62km/h
In case of gear ratio: 1:8, max speed will be ~55km/h and cannot exceed 70km/h ß Unitemotor
