Most of the recommended mirrors in this thread are specifically designed for NON-electric bikes, where the weight of every item matters.

Huge image, v.little vibration, a real safety feature. Too heavy (a few ounces) for the lycra brigade. Just check your handlebars will take the 7/8th fitting - most will.
