London’s Medieval Bike Battle Ends With Lime Issuing A Warning After Millions Watch The Chaos

Hundreds of people gathered in an east London park to witness a bizarre showdown between two men dressed as medieval knights, but their choice of transport quickly became the talking point. Instead of riding horses into battle, artist Jack Carden and actor Camtholomew the First mounted bright green Lime rental e-bikes, grabbed striped poles, and charged at each other in front of a cheering crowd. The unusual spectacle unfolded at London Fields in Hackney, where spectators could be heard chanting “joust, joust, joust” as the armoured competitors attempted to knock one another off their bikes. One rider eventually fell after being jabbed by his opponent, and footage of the encounter soon began circulating across social media.

The event was presented as performance art, with Carden describing it as a “free public joust” ahead of the gathering. A video shared on his Instagram account attracted more than four million views, turning the unusual park spectacle into a viral talking point. However, the stunt also caught the attention of Lime, which issued a warning against anyone attempting to recreate the duel using its rental bikes. The company acknowledged the medieval spirit behind the gathering but made its position clear: its electric bikes are intended for everyday journeys, not for riders to charge at each other with poles in an attempt to recreate a historical battle.

Two Armoured Knights Turn A London Park Into A Jousting Arena

London Fields became an unexpected battleground when Carden and Camtholomew the First arrived dressed in medieval-style armour, complete with chainmail and long striped poles. Rather than using horses as traditional jousters would have done, the pair rode Lime’s bright green electric bikes towards each other while spectators watched from nearby. The crowd quickly became part of the spectacle, chanting encouragement as the competitors attempted to knock one another off their rides. The unusual combination of historical costumes and modern rental bikes created a scene that looked more like an improvised medieval tournament than an ordinary afternoon in Hackney, and the moment one rider fell after being jabbed by his opponent gave the footage its dramatic climax.

Lime Responds After The Unusual Showdown Goes Viral

The company’s response acknowledged the gathering’s unusual appeal while warning against repeating the stunt. A Lime spokesperson said, “While we appreciate the medieval spirit, safety must always come first.” The company also made the intended use of its bikes unmistakable, stating, “Lime bikes are designed for getting around the city, not for jousting.” It added that it discourages similar events to help protect riders and people nearby. The statement arrived after footage of the contest spread widely online, bringing attention to the risks of using electric bikes for activities involving deliberate impacts and attempts to unbalance another rider.

The Artist Behind The Event Called It Performance Art

Carden described the planned gathering as a “free public joust” in a social media post before the event took place, presenting the unusual duel as performance art. The concept brought a centuries-old form of competition into a modern urban setting, replacing horses with rental e-bikes and traditional tournament grounds with a public park. The spectacle was accessible to passers-by who could watch without attending a formal performance, while the costumes and unusual vehicles made the encounter instantly recognisable in short video clips. The Instagram footage reportedly passed four million views, extending the event’s reach well beyond the people who gathered in London Fields and introducing the unusual performance to a much larger online audience.

Five Reasons The E-Bike Joust Became A Viral Sensation

The footage brought together several elements that made the unusual encounter easy to watch and share. Medieval armour gave the competitors a distinctive appearance, while the rental bikes created an unexpected contrast with the historical theme. The crowd’s chanting added to the atmosphere, and the eventual fall provided a dramatic moment that viewers could immediately understand. The main ingredients behind the clip’s appeal included:

• The unexpected setting: A familiar east London park became the stage for a medieval-style contest.
• The elaborate costumes: Armour and chainmail made the riders look as though they had stepped out of a historical tournament.
• The unusual transport: Bright green rental e-bikes replaced the horses traditionally used in jousting.
• The cheering spectators: The crowd’s repeated chants gave the encounter the feel of a live sporting event.
• The dramatic finish: One rider falling after being jabbed created a clear climax for the viral footage.

The combination made the encounter visually striking without requiring viewers to know anything about the organisers or the history of jousting. However, the video’s popularity does not establish that the stunt was safe or that every viewer approved of it. The available details show how widely the footage circulated, but they do not provide a comprehensive picture of audience opinion.

E-Bike Safety Raises Concerns Beyond The Viral Footage

Although the medieval theme attracted attention, the risks associated with the stunt were more serious than its unusual appearance might suggest. Electric bikes require riders to maintain their balance and remain aware of nearby people, obstacles, and other traffic. Deliberately charging at another cyclist while carrying a pole introduces additional hazards, particularly when the objective is to knock the other person from their bike. A fall can lead to injuries, while a rider who loses control could also collide with a spectator or another cyclist standing nearby. The reporting surrounding the incident also noted an increase in hospital reports involving injuries to e-bike riders and pedestrians, although no figures were provided to establish the scale of that increase or connect those injuries directly to the jousting event.

Public Performance Art Meets Modern City Life

The gathering also demonstrated how public performances can attract people who might never attend a conventional art exhibition. By staging an unconventional duel in an accessible public space, the organisers brought their performance directly to passers-by and created a spectacle that could be recorded and shared online. The contrast between medieval costumes and contemporary transport gave the event a distinctive identity, while the crowd’s participation helped turn it into a communal experience. Yet the method used to stage the performance remains central to the controversy. The competitors were attempting to unbalance one another while riding electric bikes, creating risks that could extend beyond the participants themselves.

Any Rematch Will Need A Safer Approach

The London Fields encounter has shown how an unusual public performance can capture attention far beyond its original audience, but Lime’s warning draws a clear boundary around the activity. The company has discouraged people from recreating the joust on its bikes because of the potential danger to riders and bystanders. Anyone hoping to stage a similar medieval spectacle could instead use stationary props, controlled theatrical choreography, or demonstrations that do not involve charging at another person on a moving vehicle. The costumes and historical theme can still provide the entertainment without requiring participants to risk a fall.

For now, the clash between the two armoured riders remains a striking example of an unexpected public spectacle becoming a viral sensation. The footage may have delivered an unusual afternoon of entertainment for the crowd, but Lime has made its position clear: its e-bikes are meant to get people around London, not turn the city’s parks into jousting arenas.
