My wife and I are certainly not new to biking but new to the electric community. We received her Lectric XP two weeks ago and enjoyed it so much that I ordered one for myself which I hope to see soon. Anyway, we went for a ride yesterday and it was the first time that my wife needed to negotiate getting from street level over a curb to reach the bike trail. She dismounted and walked her bike perpendicular to the curb. Being a heavy bike, she decided to assist climbing the curb with some throttle. Just as I was about to suggest using the "walk" feature instead of throttle, she gave it the groceries and the front wheel climbed just fine. The back wheel however started spinning against the curb and eventually caught catapulting the bike and my wife over the edge before all control was lost resulting in a tangled mess of wife and bike. My immediate reaction was to whip out my phone and take a picture, but survival instinct kicked in and I offered help instead. Fortunately, neither the wife nor the bike were severly injured. Lessons learned: 1) Always have your hand on the brake when walking the bike, especially when introducing any throttle while walking. 2) Use the "walk" feature instead of throttle. 3) It's probably best to stand on the throttle side of the bike so you don't have to reach so far to operate the throttle. 4) Make sure that you remain clear of the pedal or any other bike part that might catch you it the bike decides to leave without you.
