A masked gang pulled a knife on a teen and stole his electric scooter.
Five males threatened the boy, 14, with a blade while they robbed him at an Old Market Street bus stop before fleeing towards Trinity Road.
An Avon and Somerset police spokesman said officers are investigating the knifepoint robbery, which happened just before 4pm on Sunday (January 3).
"The victim had been approached by a group of five males, aged around 15 to 20 years old, wearing dark clothing and face masks," he said.
"He was threatened and his bike was stolen. The victim flagged down a police car and a search of the area was carried out but the suspects could not be found."
A family member of the victim said he is "OK but understandably very shaken".
Trials of e-scooter rental schemes started last year in many areas of the country, including Bristol. And in the last week alone, media have reported on children being robbed of their e-scooters at knifepoint in Liverpool and Coventry, while another was hit in the face in an Essex robbery.
Avon and Somerset police said they did not have any statistics to share on Bristol muggings involving e-scooters, but a force spokesman confirmed enquiries are ongoing into the Old Market incident.

“If you have information about this incident, please call us on 101 and give the call handler the reference number 5221001389," the spokesman said.
A 12-month trial run, which began on 29 October 2020, has made hop-on hop-off scooters available for hire in Bristol and Bath.
The scheme is being run by a Swedish urban scooter firm, Voi Technology.
