Turtle-Back Bike / Turtle-Back Bike

Normally when a biker meets a steep hill or stairs, the biker has to painfully drag it up. This is very common for those who enjoy mountain biking as they strive to reach higher places. To solve a such problem, we have designed the
Turtle-Back Bike. It's front wheel folds into the rear wheel and the pedals
hang on the shoulders like a backpack strap.
