This was the moment a man riding an electric unicycle on a New Jersey road has to jump for cover after the machine bursts into flames on May 31.<br /><br />Helmet cam footage shows a group of unicyclists manoeuvring in the road where one of the machines burst into flames.<br /><br />The rider in question came off the machine with such vigour he broke his leg, while the electric unicycle veered towards a tree. <br /><br />The filmer told Newsflare: "I usually go up to New York City to ride with the crew but this time I hosted the ride and we rode down the shore. <br /><br />"The unicycle that caught fire had its original battery swapped out for a larger one by a third party seller. <br /><br />"We think there was a short in one of the battery cells due to a faulty weld. <br /><br />"My friend needed an ambulance because he broke his leg stepping off and twisting his knee. <br /><br />"He then later announced his retirement from EUC[electric unicycle] riding. <br /><br />"The fire was so violent because the battery was 3108wh or 31 times larger than what the TSA allows on an aeroplane."
