I just discovered eWheels maybe a couple of months ago via researching the best eUnicycle for me. Jason @ eWheels was extremely helpful in helping me to make my decision. It basically boiled down to what would be able to support my weight - I'm close to about 6' @ 260lbs and obviously most of the entry level wheels wouldn't support that so it became a process of elimination search. It whittled down to a choice between the Kingsong 18XL and the upcoming (at the time) Kingsong 16X. I chose the 16X because it was the latest / newest and because most of the features it had in contrast to some of the similar wheels in the market along with the input of several comparisons made by those in the know. Then began the wait for release date. eWheels kept me updated on the release and even gave an opportunity for early release shipping which I took because I figured, having NEVER ridden a EUC before, I'd need to start learning as soon as possible! The wheel was shipped and received in days and I have to say that it has been one of the best purchase decisions I've ever made! I first saw a EUC in Paris a couple of years ago and was awestruck by the guy zipping by on a one wheeled device (in my mind, to and from work because my wife and I saw him around the same time on a couple of days) "What the heck is that?!" I thought and Google searched it after getting back to the states. I learned about it but didn't pursue because I live in Atlanta, GA and where in the heck would I ride something like that here? (Atlanta is a mostly Interstate heavy city with a lot of suburban outskirt cities) Fast forward a couple years and during a trip to D.C., my wife and I caught the Scooter craze after renting them from around the city and we just HAD to have our own, so endeavored to get a couple after returning home. Well one of us would get a scooter but the other would finally get the EUC he'd seen a couple years earlier. My wife bought a Nanbot 5 and I purchased the 16X mentioned earlier and after I learned how to stop falling (That only happened 3 times, I'm proud to say - twice in the same day though) I've ridden the wheel in quite a few areas despite Atlanta not being a big connected city like New York or most northern landscapes. I'm closer to 50 than to 40 and heavier than I should be but the 16X handles the challenge like a champ! The learning curve for riding isn't as terrifying as I initially thought it would be but I'm still learning - I'm even thinking about purchasing a second wheel just to have a back-up (from eWheels of course!) Like ANY purchase though, great customer service and information flow is key and Jason / eWheels has proven to be great at dispensing both.
