Charter+ 4 Lowstep is a premium city e-bike that delivers comfort, confidence, and convenience on every ride.
The easy-on lowstep frame and adjustable stem let you fine-tune your fit from upright and relaxed to more active and efficient. Road-smoothing front suspension, a Bosch Performance Line motor, and up to 110 km range keep you rolling with ease.
With a top-eject battery, high-beam headlight, and Bosch eBike Flow app security, it’s a true first-class experience.
How tall are you?
To measure your height, stand straight up, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.
What is your inseam?
How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
