Renewed interest in biking! Pre- Ordered a GEN 2 kit several years ago with the understanding delivery would take about 10 months. Patience is key. Installation was easy and results were better than expected. Now I ride a lot with average trip being 40km. Use PAS sparingly (0 on flats, 1-5 for slopes/hills) and have never ran out of power. Did have judder issues that were resolved after changing handlebar bracket, battery bag, controller over 3 seperate interactions. Customer service was prompt and accomplished via on-line interactions (no phone calls). Will probable upgrade to GO kit once Gen 2 battery pack depletes
