Got my Kingsong 14D about a month ago, but have been limited to weekend self-training, as my work schedule has been ridiculous and I was awaiting the arrival of Daylight Saving time to finally get some weekday after work hours training in. First of all, let me echo what everyone else has said: Jason and the team at eWheels are awesome to work with! Their patience, quick response and great tips have all been invaluable to me in getting started. After a good 10-15 hours of practice, I am finally comfortable with this awesome wheel, but admittedly have to work on my sidewalk transition and turning skills before I take it into Washington, DC for my final 2 miles to work from the subway, with no more waiting on the bus (post COVID-19 lock-down and the end of my teleworking schedule,m of course). One of the initial challenges in training was not knowing about calibrating and once that was complete, it was game on! Kingsong has made an awesome gadget at a reasonable price point and you won't be disappointed. This thing has plenty of speed and I don't see myself wanting to do over 20 mph anytime soon. It's easy to maneuver, provides a good body-toning workout when carrying the close to 30 pounds of tech, and If I may offer a piece of advice, even though these wheels are built to take spills on the concrete, if you can locate a middle or high school with a rubber track, any spills will feel better on your body and your wheel won't suffer any scratches. Take advantage of the kids being out of school and practice on their tracks or artificial turf fields. Get your helmet, knee and elbow pads and be sure to check out your model (and other models) on YouTube by the guys and gals who got a head start in discovering these awesome technological machines; you will learn a lot from them. Don't rush your learning and don't give up; it will become natural and easy before you know it. Safety and common sense first and happy gliding!
