EcoRider Mark9 model is a unique three wheel mover that is made in Singapore. The proprietary gyroscopic control function enables Mark9 to operate in a similar way as a traditional Segway (with zero turning radius). The front third wheel provides a completely stable platform that enables safety of the rider at all times, while still allowing the forward/backward movement controlled by the rider's weight distribution. Turning is controlled by the handle. This revolutionary design enables the Mark9 to be customized according to customer's needs. Mark 9 can be tailored for indoor security patrolling, hospital portering, warehouse transportation and more. With more than 13 years of experience, EcoRider seeks to provide the most durable personal mobility transporter to customers. Mark 9 is designed with minimal maintenance in mind, hence there is no need to change tires or service the brakes. The UL certified battery needs regular charging and it has a useful lifespan of 2 to 3 years.
