TL;DR

A 17-year-old named Yosman Stiven Cossio Urrego died in a gravity bike accident on the vía Las Palmas in Medellín.
He lost control of the modified bicycle, which was equipped with weights, and collided violently with the pavement.
Gravity biking involves modifying traditional bicycles with weights to achieve high speeds downhill, often exceeding 100 km/h, and typically lacks brakes.
Yosman's girlfriend, also 17, survived the crash with multiple injuries and was hospitalized.
This incident marks the eighth death related to gravity biking in the year, according to official records.
Another case is highlighted: Emmanuel Vallejo Morales has been bedridden for 12 years due to a similar accident in 2013, requiring constant care from his mother.
Practitioners like Alejandro García (Popeye) express passion for the sport, citing happiness and adrenaline as motivators, despite acknowledging accidents and the deaths of friends.

La Ceja has banned gravity biking by decree.
