★What is a fat bike? It is a mountain bike that evolved for the purpose of riding on snow. On this tour, you will be cycling along snow-white ski slopes. There is no such thing as ``slipping or brake failure'' that everyone tends to worry about! The reason for this is that the tire width is about 12cm, which means it has a large footprint on the snow, and it is equipped with a disc brake, which is the same system as a car. Our fat bikes are stocked with popular models from top bicycle manufacturers, and are maintained in good condition by our guides who are qualified bicycle safety mechanics. We have 20 inches for children who are over 130cm tall, 24 inches for juniors, and 26 inches for adults. You can also invite your family and friends to participate. On this tour, a dedicated guide will accompany you and carefully explain how to run and play, so even first-timers can feel at ease! There is a warm rest house and restrooms nearby, so children can participate with peace of mind.
