Electric scooters are all  rage in many cities across  world. The electric-powered two-wheelers are helping people nimbly zip through traffic and effortlessly get about town. However, they have also brought problems and safety concerns. Many scooter riders disregard road regulations, ignore traffic lights and illegally ride on sidewalks.  major scooter manufacturer has started selling  speaker that will alert pedestrians and other road users of  scooter's presence. Segway is marketing  new speaker accessory that can add V12 engine noises to its scooters. Alternatively,  user can plug in their music device and  speaker will boom out  rider's favourite tunes.
Segway's $150 Ninebot Engine Speaker can play music or revved up sports car sounds for 23 hours when fully charged.  speaker syncs with  scooter's accelerator, so  faster the vehicle goes, the louder  speaker's rev sounds are. Segway said its engine speaker acts as  continuous warning to anyone in earshot that the rider is approaching. Many road safety analysts believe  speaker could reduce the number of collisions between scooter riders and pedestrians. However, critics are concerned about  increase in noise pollution. They say the beauty of electric engines is their silence. They believe  simple beeping sound is sufficient to alert other road users and  V12 sound is overkill.
