The weight of an Ahooga Push Bike is only 10 kg (22 lbs). An Ahooga e-bike, depending on the model, weighs between 13 kg for the Essential (29 lbs), and 15kg (33 lbs) for the Power+, with the electrical system (motor and battery included).
With such weight, the Ahooga is twice as lighter than any other folding bike. That is why, even without using the battery, the Ahooga remains light and easy to propel. You do not depend on the battery, which is even better for the planet :-)
