Technical Details


Product Description

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.

Okay. It would be easy to make this a very long review. I'll try to keep it short. A friend of mine told me about the SBU two years ago. So it took me this long to pull the trigger. I travel a fair amount in my motorhome, Or on my sailboat. And this year in July I tore my disc in my left knee. I was having a hard time doing a lot of walking. And was considering electric bike. But they are just too bulky to be very portable. So a couple of months back I finally purchased an SBU.
In less then a week I was riding it like a pro. Was literally able to carry my coffee, drink it. While walking my dog on the unicycle. I now use my SBU every day. As of yet the range has never let me down. And I have gone on some very long rides. I am 50 years old. But learning it was very easy. I tell people it's more like a bicycle then a unicycle. What I mean by that is you can't fall forward or backward. And as soon as you figure out how to steer with your hips. Then it becomes very easy and natural. I saw a review where someone was saying they wished it had handlebars to give you a better feel. After ridding it for just a bit you will see that is ridiculous. I love going over to Starbucks in the morning and getting two coffees. One for me and one for my wife, And riding home. You can't do that on any bicycle, or anything with handlebars.
I made two YouTube videos. One of me commuting, and passing a bicyclist. The other of me walking my dog with my coffee. That was only after having had it for a bit less than one week. Thank you focus designs for such a great product.

This device is built with real quality. You can tell that it went through a lot of testing. It is made from SOLID materials that perform well and can last over time. The control software is really well tuned. This is not a toy! It is a professional short commute vehicle. It is a pleasure to own and ride.

After owning the original (V1) SBU I recently upgraded to this third iteration of the product and am REALLY IMPRESSED with the new design! The new footpeg style/position makes it easier to get on/off safely and allows the SBU to stand on its own (leaning to one side) when I take it on the subway. The lower center of mass that comes from putting more stuff IN the wheel and frame makes it easy to walk the device when you have to hop off for any reason. The more powerful motor and battery make it easier to climb hills and get where you're going without running out of power. The new power switch is easier to read with its bright blue pulsing LED. A lot of thought and care went into this! It is fun to ride and people enjoy seeing you ride it. With my hands free I can even juggle or play guitar or have a beverage while riding!

It's worth mentioning this is a POWERFUL device. To go full-out ("max speed") is subjectively pretty scary - I wouldn't recommend doing so without a helmet and elbow/wrist pads and a very flat obstruction-free surface. I prefer to keep it down to a jogging-type pace, not a running pace. The fact that you CAN get up to 12.5mph on a one-wheeled vehicle doesn't mean you SHOULD. If you keep leaning farther forward it eventually MUST fall down - physics says so. No matter how smart the electronics are, this product shares with bicycles the property of being really not all that inherently stable - getting scared by a dog or hitting a too-large crack in the sidewalk can be dangerous. So pay attention to what's around you, don't push the limits and SLOW DOWN as you approach people or hazards.

But with all that in mind: get this product! Try it out and have fun!

Verified Purchase
Worked great for 2 weeks then all the sudden it freaked out bucked me off and dragged itself into the trees. It had also had no prior crashes. I charged it and pumped the tire and i worked until i came to a little bump in the sidewalk (something i had passed without problem countless times) and it freaked and did the same thing i had to jump on it and turn it off so it wouldn't run in to the street. Now anytime in hits a bump of any sort it happens. My crashes also resulted in scars on my knees and elbow. I also thought originally when it freaked it world stop but it wouldn't without being turned off manually.

UPDATE: I can no longer recommend this product in its current form, it might be very dangerous. I've reduced my review to one star, details follow.

This is a very fun product and I was riding it every day including commuting to work. Unfortunately after less than a week I had a very bad crash on it at max speed and broke a bone in my elbow and hit my head hard enough to give me a concussion and daze me for a few minutes (luckily I was wearing a helmet). Because of the head injury I don't remember the crash but immediately after the SBU malfunctions in a very bad way. If I turn it on now and move it back and forth by hand it will self balance for only a short time before it goes crazy and falls to the ground. I'm am returning the product. I'm lucky I only broke my elbow, it could've been much worse.

I want to support small green companies and I really like the idea of the SBU. I might buy this product again one day if it matures and includes redundant groups of gyros/accelerometers/sensors that can self-verify each other and determine malfunctioning sensor/software while still keeping the cycle balanced to stop it safely. I believe it does not have this sort of safety feature now and so any sensor or software malfunction might be very dangerous to the rider. I don't know if that's what happened to me, but regardless my broken elbow and I cannot recommend this product in its current form.

Original Review follows:

I've spent hours riding my SBU V3 and I've only had it a few days. It's just too much fun. You get a lot of stares, thumbs-up, and other attention too.

It comes assembled, you just have to attach the seat and charge it. If you need a shorter seat they include a smaller pole (which you'll have to attach to the seat).
