Hive a liberty trike when operated for the first time after charging works fine in all 5 speeds then after a few minutes in #1 speed , the drive motor almost sounds like it is laboring (vibrates) then in 2nd speed nice and smooth 3rd speed fine then 4th speed it shuts down , during this time if I raise the front wheel off the ground it won't spin unless you first spin it by hand. Any body have a clue? Thank for listening Mark

Probably a hall sensor in the motor is bad.
