My 48V 2000W Diamond Back Mountain Bike with 52V 20AH Bat

This is my second hub on this bike and by far the best. This 2000W hub/wheel has all the power needed to climb the numerous hills around my house. The weight of this hub is amazingly light and actually freewheels so I can peddle (only) unlike the hub I purchased on Amazon from another vendor. I use this with the 52 volt 20 AH battery also from Calibike. Calibike has been very supportive with very quick responses to all of my questions.
