    Bent rotor

    The front brake rotor arrived bent. While Addmotor would not cover it Electric Bicycle fully refunded the repair bill. I would definitely buy from them again

    Battery lasts a long time!

    Got it for Christmas. My husband got the men's version. We took them to San Diego and camped at Silver Strand Beach. Rode from there to Coronado, to the Ferry Boat. Crossed over to Seaport Village. Came back and and rode back to camp. About a 17 mile trip. We are both in our 60's. We used the battery quite a bit on that trip and when we got back, only half was used on his and less than half on mine. I had mine in 3rd ad 4th gear most of the time. I am very please with this bike. I give it 5 stars!
