I've been shopping for an ebike and I haven't found the exact bike. Easy Motion Evo Street is looking good except I think I need a bigger motor than 350w due to my weight. I have a regular bicycle that is perfect for me and now looking at conversion. I'm not mechanically inclined and at a loss. My bike is a Trek comfort bike, step through ladies frame with 26in tires. Shifters are little not twisting. I think 21 settings. Thanks!
