My ebike came mostly assembled in a large box. In three weeks I have 200 miles of city riding on it. I am a female, 5’4” and 61 years old. My Espin is an investment in my health. As other reviewers have mentioned, the controls are intuitive. I just had a flat tire yesterday but I walked my ebike to the local bike shop. He fixed the tire with tire liner. He described my ebike as “sleek”. I plan to eventually invest in puncture resistant tires.
