Main difference is that 500w accelerates faster and stops "faster" - hydraulic brakes. On either one you must rotate pedals before the throttle kicks in. Going uphill from dead-stop is a bummer on this one . Try holding the down-button to activate the Walk mode, rotate pedals at the same time and then activate the throttle.Hmm...Can you explain that last thing about the difference between the 350 and 500? I just received my 500. I'm almost 65, and I see a few problems I will have to get better at dealing with. One being stopped at a light, and when I can go, and it's a steep hill, how to get going, when I can't get the pedals moving! I haven't downshifted to the lowest gear yet. I will try that next time. This time, I walked the bike up the hill. UGGG.
