This bike boasts 14 speeds in addition to a step-through frame. 

As you'll soon discover, the advantage to electric assist bikes is that you enjoy the benefits of the exercise but the bike is there to do its part. The motor is silent but its gentle push makes an amazing difference. Since pedaling is easier - even uphill - your pedaling becomes more consistent, thereby creating a more steady aerobic workout. 

What's more, your pedaling actually powers the clean electric hybrid motor. The bike utilizes your energy before the motor takes effect.

This bike is an ideal way to return to this wonderful hobby after a long hiatus or to perform your daily commute.
