The y-belt can be adjusted to fit the passengers perfectly and gives the passengers a great level of safety. It is available in two variations; one for children, and one for seniors. It is bolted securely to the box to withstand a powerful braking and can be used with our wooden bench, the tip-up seat or with the soft seat. The y-belt is made of strong nylon webbing and with soft pillows around the shoulders to protect the passenger and for improved comfortability.
