Suitable for groups of all stages
Thanks to its low frame, light weight and foldable features, it was created for the elderly. However, it is also suitable for people of all ages due to its practicality.

Easy to reach
The wide seat is ergonomic and makes long-distance riding painless. The refined shock-absorbing front fork is the highlight. You don't have to worry about cobblestone roads.
