How tall are you?
To measure your height, stand up straight, 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.
Verve+ 4 Lowstep is an electric hybrid bike perfect for riders looking to go far and have fun on daily commutes, recreational rides and workouts. It's as rugged as it is sleek and features a powerful Bosch BES3 drive unit with smart system integration, and four different battery options at 400 Wh, 545 Wh, 725 Wh and 800 Wh for you to choose from. This e-bike comes equipped with parts that put your comfort and safety first, like a suspension fork and seat post, wide, stable tyres and integrated lights.
