OUR OPINION

The best foldable E-Bike with Bosch motor!

Ideal for commuting, we see it as a smart investment for covering long distances, hopping on public transport, or navigating the first and last commute legs with speed.

While its foldable design is convenient, it does come with a bit of weight.

We recommend it for those who genuinely need a foldable bike for specific uses like buses, metros, trains, car trunks, or elevators – this should definetely be the go-to choice!
Keep in mind, carrying it upstairs might be a bit of a workout.

The bike folds seamlessly, thanks to a robust magnet ensuring a secure connection between the rear and front parts - adjust it easily for a snug fit.
To keep the handlebars secure and compact, a strap with multiple hole options is included.

Pro Tip: Take advantage of the reengineered bike saddle's underside, turning it into a comfortable grip and shoulder pad for easy bike transportation.
