History of Tandem Bicycles

Patents related to tandem bicycles date from the late 1800s.[1] In approximately 1898, Mikael Pedersen developed a tandem version of his Pedersen bicycle that weighed 24 pounds and a quad that weighed 64 pounds.[2] Tandem popularity began to decline after WWII until Bill McReady at Santana Cycles instigated a revival.[3] Modern technology has improved component and frame designs, and many tandems are as well-built as modern high-end road and off-road bikes.

Collection tandem bicycle from buddy bike

The Buddy Bike - The Alternative Tandem Bicycle. The Buddy Bike is an inline tandem bicycle (bicycle for two) that places the stoker in the front seat while the rear rider controls the steering. It is shorter in length than a standard tandem and has a lower front seat so both riders can safely enjoy the view. The Buddy Bike can support up to 380 pounds; making it the ultimate family bike that can be enjoyed by riders of all ages and abilities. Its features make it especially beneficial for special needs children who otherwise would not be able to experience the thrill of riding a bicycle. Utilizing this unique patented design and quality bike parts, the Buddy Bike provides safety and REAL quality time!

Buddy Bike provides safety for child riders. When your child is too big for the baby seat and too small to ride alone, riding with your child behind you on the old-fashioned tandem or tag-along bike can be a risky experience. With the Buddy Bike, your child sits directly in front of you, between your arms. You no longer have to twist around to check on your child, losing your balance and risking an accident.

Buddy Bike provides REAL quality time for the whole family. On the Buddy Bike, your child will love being out in front with only the road ahead, feeling like they are in charge, but knowing they are still close enough to get verbal encouragement and an occasional kiss! What a great way for a child to learn how to bike safely, get great exercise and enjoy real quality time with mom or dad! The Buddy Bike can be ridden alone or by two adults. It can be a useful tool for teaching older riders how to ride a bike. The Buddy Bike is the ultimate family bike. It can be enjoyed by riders of all ages and makes a wonderful addition to bike rental fleets.
