The IZIP Sereno Electric Bike is a very well-constructed bike, just like the rest of the IZIP line. As a quality E-Bike, you of course have the option of traveling in fully manual, electric-assisted, or fully-electric modes. Due to it's bigger, sturdier design, the IZIP Sereno tends to be very durable, even at it's top speed of fifteen miles per hour (15mph). Electric bikes are always a great option for Eco-conscious consumers, as they don't create gas pollution as a byproduct (and are cheaper to run to boot!). The Sereno also includes a convenient basket for carrying whatever you might need a long for the ride.
