The SBU V3 is precision crafted by hand with 6061 alloy. Built to last and to stay pretty, the SBU is ultra-portable and is capable of 325-lb loads and beyond! No handlebars, no steering wheel, no need for any of that! Control your SBU with natural leaning motions (similar to the Segway) and experience a new way to travel. Lean forward to go, lean back to slow down/stop. The Focus Designs Pure Sine Wave controller is more advanced than anything you can find on the market. With regenerative braking, unmatched efficiency, eery silence, and torque-control at the granular level, this BLDC controller is the only one it it's class. The SBU takes about 20-30 minutes to learn and once you master it you'll find that riding becomes as natural as walking and chewing gum (only way cooler). Using some cool features like Turn AssistTM and Smart SenseTM the SBU V3 actively "learns" your motions and performs numerous safety calculations every second you ride. Multiple 3-axis accelerometers and gyros provide superior inertial measurement enabling for a ride like no other. When you turn, the SBU's motion-learning algorithms detect your intent and provide stability assistance throughout the turn. It's a lot like having a sloped embankment for a racecar driver; only Turn AssistTM help is provided with software and 3-axis sensors. Navigate through narrow turns. It can handle a lot, but if you push the SBU near its physical limits, Push BackTM will kick in and push you backwards, telling you that you need to ease off. Upon a depleted battery, your SBU will gently immobilize by slowing your motion to stop while still safely maintaining balance. Smart SenseTM software automatically and carefully shuts the SBU off upon sensing any abuse or an accidental crash. It's clean. It's green. It's an elegant machine! The SBU's portability makes it the perfect in-between commuter as it fits on the bus, the subway, the train, and underneath your desk at work.
