The Electric C Line. The original folding bike, loved by hundreds of thousands, with the added oomph and ease of electric. It’s a real-life magic carpet ride. There when you need it, tucked away when you don’t.

We’ve been unlocking cities around the world,underground and overground, since 1975 – connecting people and places with our famous folding bikes. And for a bike that’s given so much, would it be fair to ask for more? Well, why not? Because we could all use a little help, whether it’s work or play. Here’s the bike you’ve been waiting for.

Hills? Errands? Weekend adventures? With our Smart Pedal Assist, you can go further, faster and even higher. The compact motor does the hard work for you. And when it’s time to go again, rest easy knowing the lightweight battery quickly detaches from its secure mount, so you can take it with you and charge wherever is convenient. With the most compact folding e-bike, you can do it all.
