In the United States, the Dusty is classified as a Class 3 electric bicycle and can be updated as such. As standard, the Dusty ships to the US as a Class 1 e-bike, meaning the pedal assistance stops when the bike reaches 20 mph. However, the bike can be updated to a Class 3 e-bike so that the TQ HPR60 motor delivers assistance up to 28 mph — the maximum threshold permitted under the U.S. three-class e-bike framework in the states where such legislation applies.
Some land managers and trail systems restrict Class 3 e-bikes on natural-surface/singletrack trails even where Class 1 is permitted. Riders must confirm state legislation and local trail-access rules beforehand and check state-specific requirements (helmet, minimum age, and in a small number of states, driver's license).Dusty remains pedal-assist only in this configuration, with no throttle, distinguishing it from Class 2 systems.
