The company isn't resting on current products. They have introduced a new Mini in China. It has longer range (20 miles), storage (in the control bar), and a "follow me" mode.
The follow me mode looks to be a most useful mode addition to the remote control option found in the MiniPro. Easier than the constant attention required to remotely operate it.
The batteries are now located in the center hump the control bar attaches to instead of below the platform. Higher ground clearance?
Price, in China, looks to be the same as the Chinese version of the Segway MiniPro. $540-ish.
