I think this is an issue better-resolved by separating traffic modes. Strapping noise makers on to a vehicle to make it safer is a sort of "pseudo-solution" which hops around solving the core issue.

Electric bicycles traveling that fast probably shouldn't be permitted on the same channel/road that foot-traffic uses. Though I don't live in Beijing so I can't speak to their decision (or lack of) for that.

Likewise, in the U.S. I've seen a few downtown areas try to be "green" by simply throwing some bike lanes on a 5-lane road. It's quite dangerous to ride a bike along that because of the traffic going 35-40mph. Separate that bike lane with bollards, at minimum, or build a separated "sidewalk" for e-bikes and scooters. Putting bicycles on the same road as 3,500 lb vehicles hurtling at 40mph is a joke.

One reason to like Seattle is that they actually have bike trails, not just lane separation with car traffic.

Beijing used to have a lot of such bike lanes in 1999 when I first visited (the land of the sea of bicycles) but sadly all of this has been turned into parking for cars.
