Our inconspicuous electronic hub assists your pedaling so you can maintain your speed. All it takes is switching out the rear wheel of our classic hybrid bikes. A control device on your handlebars helps you decide when the motor kicks in and how much assistance it provides. Lighter than a standard electric bike, the entire e-wheel system weighs just 3.7 kilograms. You get the support without anyone knowing. It’s your little secret. Limited availability: E-wheels are offered for an upgrade fee on a first-come, first-serve basis.
