Hey George,

Thank you! GM does provide separate controllers, we do not use them however. We have a completely Focus Designs-designed BLDC motor controller. Our custom electronics are really the only way we would be able to precisely control the balancing of the motor. It also has MEMS sensors to provide balancing feedback.

Hmm… Athens… Let me think about it, YES! We would love to head over there. Things are very busy for us at the moment but could we take a raincheck? We’ll try to find a few other reasons to head your way but we would be honored to come and meet your ME students.

I have two of these 1KW motors (golden motors) on my mountain bike coupled with a 54V/12Ah LiMn02 battery, totalling 2KW. Trust me, it is very ok power-wise. On certain occasions, even with this power it stalls, exactly because of torque being delivered without any gearing, especially considering that I’m 1.95m tall and 110Kg.

I admire the very clever thinking in this project. The GM hub motor has a forwards and backwards function, which is usb programmable via the in-built controller. So, I guess they coupled a microgyroscope chip with the throttle controls and the forwards/backwards function and got it running. Any chances the “glueing” utilised C in a Linux running Atmel?

I really wonder how it would cope with my weight/height and rather difficult Athenian terrain. I guess there’s only one way to find: how about some holidays in Athens stay at my place, show you around town and introduce you to my mechanical engineering students?

cheers
George

Ha, that is awesome!! it should totally have AWD on the unit somewhere also.

I would love to see an ‘off-road’ mountain-bike style version. All terrain is the best!!

Thank you Ron,

I had a blast speaking to the kids and I would love to come back and bring more hands-on experiments to help the kids learn closed loop systems.

You are fascinating, wonderful, caring people.

Ron

Unicycling since 4th grade eh? You probably think we are all cheaters – this is much easier to ride. 🙂 We put the Kenda Kiniption tire on here and can use any standard 20″ tube/tire. The seat is a Kris Holm Unicycle seat. You can change the tire, tube, and seat at your leisure. We would be happy to solve any mid-life crisis issues. Shoot us an email at sales@focusdesigns.com about distributing. We are setting dealers up in the future and can put you on the list.

Thank you for your business. David

Richard Masoner was my college buddy and best man at my wedding (FYI).

I am an unicyclist since 4th grade. After riding one for many years, I have experienced worn tires, broken seats from unfortunate falls and flats tires. Where do we get the spare parts from? Are the seats compatible with traditional unicycle seats? The banana seats are comfortable.

I love the idea of the overkill on the motor since, I plan to ride mine quite a bit on uneven terrain with a couple of hills here and there.

I was just about to purchase a Segway for my mid-life crisis purchase, but I believe that I will be getting an SBU instead.

Do you have any distributors yet? I would be interested in selling this on the side.

Hey Tessa,

Yes we do ship internationally to Indonesia. I believe shipping to Indonesia was just over $199. If you’d like more information just shoot us an email.

Thank you for checking out the Self-Balancing Unicycle.

Hey Israel,

You can buy the SBU only direct from our website and we directly ship them to you. Visit http://www.focusdesigns.com/products-page to place an order.

Thank you for checking us out!

Hey Reo,

Yes, we do ship to Japan! visit http://www.focusdesigns.com/products-page
