My Literider 2.0 ebike came assembled. The frame welds and paint are high quality. After inflating tires, it was ready to street test. I am a 73 old retired Architect. I have not riden a bike in 60 years. My surgeon suggested an ebike for a post surgery tool to get up and be active. With the pedal assist design, it helps me with hills. When my legs get fatigued, the bike helps me return home.
