A step-through bike is a type of bicycle frame that has a low or absent top tube or cross-bar, making it easier for the rider to mount and dismount without having to swing one leg to hip-height. Here are some key points about step-through bikes:
-
Design: A step-through frame is much like a step-over frame but without the top tube. This allows riders to easily slip into the saddle without having to lift their leg over the frame.
-
Types: One particular type of step-through frame is called a mixte. In a mixte frame, the top tube of the traditional diamond frame is replaced with a pair of smaller tubes running from the top of the head tube all the way back to the rear axle, connecting at the seat tube on the way. The normal seat stays and chain stays are retained. This provides the lower standover height of a step-through frame bicycle with a strong diamond-frame geometry.
-
Benefits: The ease of maneuverability is one of the main benefits of step-through bikes. Getting on and off the bike is effortless, making it a popular choice for delivery bicycles and other purposes where the rider has to mount and dismount frequently. Step-through bikes also offer riders a more upright riding position.
In summary, a step-through bike is a type of bicycle frame that is designed to make it easier for the rider to mount and dismount without having to swing one leg to hip-height. It is a popular choice for delivery bicycles and other purposes where the rider has to mount and dismount frequently.
