Santa Monica Recreation & Parks Commissioner Phil Brock test-drives an A2B by Hero Eco e-bike at the Santa Monica Pier during a press conference on Tuesday, May 7, 2013. A2B is the premium range of e-bikes from Hero Eco which features a full suspension, thick-durable tires, and a plush seat that makes for an extremely comfortable ride, even on rougher roads. Front and rear disc brakes allow for safe riding in all kinds of weather. With a 500W motor and 20-inch wheels, you can expect a lot of torque for hill-climbing. Combine that with 7-speeds and you have all of the range you'll need for the inclines and the flats. The lithium battery is located inside of the frame tubing and completely hidden from view. Simply turn a key to activate the system and go. The same key switch can alternate your power source to an optional second battery that locks into place just under the rear rack. The bike comes standard with one battery that will get you up to 20 miles per charge. In order to increase your range to up to 40 miles per charge, the second battery is available for purchase as an add-on. Your battery life can be easily read from a battery gauge right on the throttle.
