Snow Traveler / Bicycle

This bicycle-- Snow Traveler can switch modes between snow bike and land bike. It’s applicable to a lot of weather. Its central structure contains two auxiliary wheels which can be expanded in rotation. They increase the contact area and friction, which enables users to travel smoothly in snowy days and guarantees their safety. The two auxiliary wheels are on both sides of the wheel. Usually, the bike can be used normally on land when the auxiliary wheels are retrieved. The dual-purpose concept bikes have broken the single-use scenario of traditional bikes. They increase new functions and make the riding experience more enricher.
