Hi Ya'll, I have been in search for a light weight foldable e-bike to take traveling with me. I am 65 year old women and can lift about 50 pounds (if I have to) but would prefer 40 lbs. Also the bikes that I have tried did not have a very smooth transition from peddling to and the battery kicking in. Are their some that have a better intergrated system out there. Appreciate you advise and wisdom. I like the fatter tire bikes.
