Yallstore via eBay offers the Segway MiniPro Smart Self-Balancing Personal Transporter in Black for $499.99 with free shipping. That’s the lowest price we could find by $94, although we saw it for a buck less last month. It features top speeds of 10 mph and distance of 14 miles on a full charge. Connect to the app via Bluetooth to get remote control operation, anti-theft alarm, speed control, customizable lights, vehicle diagnostics, and firmware updates.
