This is a powerhouse of a electronic bike with front and rear suspension, with extra suspension technology built into the seat post for maximum comfort, Morning to Night (MN). A step-over bike, the MN has 7 speeds, with a frame that folds up neatly, allowing for easy storage in the trunk of your car and it won't take up a lot of space at home. No need for a bike rack! This bike has all the bells and whistles, including a 3v smart charger, a rear rack to carry the day's supplies, and to protect it all, a motion-sensing alarm that you control with wireless remote. Weighing in at 72 lbs (with battery), and with a bike length (front-most tire to back-most tire) is 69", with a max seat height of 42", and 34 inches at its lowest seat position, this bike is ideal for adults that are 5'2" and up.
