Jousting on bikes is a “legitimate” form of the sport, a professional jouster has said before a duel on Lime bikes.

Earlier this month, footage emerged on social media of hundreds of spectators in London Fields, east London, watching artist Jack Carden and actor Cameron Carnegie-Brown, known as Camtholomew the First, joust in an earlier duel while riding the bright green rentable e-bikes.

The videos show the men wearing chainmail, red and black cloaks and armour, including helmets, as they ride towards one another brandishing striped poles.

They have since advertised a “rematch” on their social media pages, which is expected to take place on Saturday at a location yet to be announced.

After the first duel, Lime released a statement saying “while we appreciate the medieval spirit, safety must always come first”, adding that its bikes were “not for jousting”.

The company discouraged riders from “attempting similar events”.

Andy Deane, captain of the Royal Armouries jousting team in Leeds, said it was a “joy” to see the bike jousting “capturing the spectacle” of the medieval sport.

“This is absolutely a legitimate form of jousting,” he said.

“Historically, you had sort of piggyback jousting pictures in the 14th and 15th century. You had jousting on water where you had people rowing boats towards each other with people at the bow with their lances and shields.

“So bicycles – absolutely the way to go. Certainly if you can’t afford a horse.”

Mr Deane has been jousting for 33 years and has travelled across Europe, Asia, Canada and the US performing and teaching the sport.

“Bringing the lance down and holding it firmly to hit a very specific target is difficult when you’ve got all the other things going on,” he said.

“So messing around on a bicycle in the middle of a park, you’ve got uneven surfaces, you’ve got an uneven speed.

“One might be going faster than the other, and so it’s all hand-eye co-ordination, and again, it sort of comes down to practice.

“What is a joy to see is that Lime bike jousting is capturing the spectacle of medieval jousting,” Mr Deane continued.

“You’ve got hundreds of people getting really enthusiastic, laughing their heads off and cheering on the knight they want to win.

“That’s what jousts are all about. They’re loud, rambunctious, brilliant places to perform.”

He said the sport’s biggest danger was being flung from your horse or bike and “landing badly”.

“There’s definitely a risk involved, but that’s why you’re wearing the armour – to protect you and, for the most part, it does,” he said.

Lime has been contacted for comment.
