A local pedal bar company blasted music so loud that the driver could not hear panicked screams when a woman's foot slipped off of her pedal and slammed against the pavement, according to a lawsuit filed last week.

The suit, filed against the Sprocket Rocket company and an "unidentified" driver, claims that plaintiff Michele Calabria suffered "serious, disabling, painful and permanent bodily injuries" during an Oct. 23, 2016 trip on one of the company's pedal bars.

According to the complaint, which was filed Thursday in Davidson County Circuit Court, Calabria was pedaling when her foot slipped and hit the pavement.

"Her body was thrusted (sic) forward onto metal bars, and her foot was dragged several feet," the complaint read.

"The music was too loud for the Defendant Driver to hear the screams asking him to stop," the complaint read. "After several high-pitched screams the Defendant Driver finally stopped the party bike and tavern."

Sprocket Rocket did not immediately return a Tuesday morning voicemail at its business office requesting comment.

According to its website, the company currently requires customers to sign a waiver that says, "I fully understand that the Activity can be HAZARDOUS, and involve unknown risks and unanticipated risks which could result in BODILY INJURY ... I fully accept and ASSUME ALL SUCH RISKS." It is unclear if Calabria signed the waiver, or if the language was the same a year ago.

Although the complaint suggests Calabria's injuries were serious, it does not specify what they were. Her lawyer did not immediately return a message requesting additional details.

Sprocket Rocket markets itself as Nashville's No. 1 "party bike and tavern tour" that allows riders to drink and sing along to songs while sitting on bike seats and pedaling to power the vehicle. The company's website promises prospective customers a ride on "an all fun party mobile machine for folks who take their revelry pretty seriously."

According to the website, participants must pedal to keep the vehicle moving forward. But a motor also powers the motion.

Bars on wheels in all of their forms — including pedal taverns and tractors — have been a controversial addition to Nashville streets as the city's tourism industry has boomed. Companies have faced off against one another in lawsuits and the city government has worked to limit their operation.

The complaint accuses the driver of being "careless" and "negligent," and of playing "booming music" that was so loud it violated Metro code.

The company and its employees "acted with a conscious neglect of duty or a callous indifference to consequences," the complaint read.

Calabria wants a jury trial on the incident and a money judgement of up to $750,000.
