I had a hard fall 3 days ago the resulted in me fracturing my Humerus (upper arm) bone. I’ve been skate boarding and snowboarding for many years so riding the one wheel was very natural. I’ve also read a lot of stories around here when trying to hit the top speed and so I never attempt it nor do I ever try to push through the push back. I think the top speed recorded in my app is around 18-19mph and I’m sure it was downhill at some point. But I’m very happy staying under 16mph.
Anyways I was just casually riding to my mailbox which I do on the one whee daily. I was on the road accelerating and was at around 14-16 mph in a straight line and the front of the board just dropped during acceleration and was able to run it out for 2 steps before I came crashing down. I was in complete shock that the board just dumped me forward and my first thought was to go and check if the board shut down. Painfully got up and checked and the blue light was on. So I was accelerating on a level street and the front dropped me at around 15 or so mph. I had scrapes across my knee, stomach area and my arm. But the impact of my elbow to the road cause me to fracture my humerus bone right in my shoulder socket and not sure how bad my muscle is there but I am unable to lift my right arm or use it in any way that requires strength. Doctor says it will probably take about 6 weeks to heal.
I’m not blaming the one wheel here, but I’ve been riding it long enough in various terrains to know what I’m doing. I’m also not pushing the limits. I think it happened in a quick transition between accelerating at a quick pace and then going neutral. There could have been slippage on the road or something. Without data, it’s just hard to know what happened. I’m still riding the one wheel even with the injury, but I’m keeping he speeds to 5-10mph on the street until I can gain trust again (and heal obviously). But I do think there must be certain scenarios that can cause the front to drop too quickly in an unexpected way. Just the nature of trusting software to always keep you balanced in a single wheel. I think my lesson is to take it easy on acceleration and make sure my body weight is always leaning back instead of being so neutral, especially at higher speeds.
