I can keep up 28kmh all day comfortably on my road bike and I’m not that fit but that’s 8 kg of carbon fibre running on 21mm tyres at 120psi not your average commuter bike.

I ride much slower on mixed use paths or around pedestrians, me hitting someone at 32km/h is going to hurt both of us potentially badly.

> I cycle somewhere between 20 and 35 km/hour; that's faster than scooters and most electric bikes.

This makes no sense. You can pedal an electric bike at least as fast if not faster than a regular bike.

Some e-bikes are speed limited to cut out the assist at a certain speed, but it doesn't mean it also removes your ability to pedal hard and achieve the same speed.

They generally reduce their assist and completely cut out at 28 to 30km/hour, so to actually cycle 30km/hour takes as much effort as it would on a normal bicycle.

Most Dutch cycle at about 25km/hour (whether or not electric) - those cyclists that easily do 30 on normal city bikes are probably the last generation that will switch to e-bikes.

The electric assist on e-Citibikes here in NYC diminishes with speed and cuts out completely at around 15 mph. Above that speed they're just a heavier normal Citibike. I know because I've enjoyed pushing these things to their limits.

There are many different types of e-bikes, and you're probably thinking of what are effective electric mopeds, with big batteries and engines and a throttle control. Those certainly go very fast. They're also not legal in many places, including here in NYC, and aren't necessarily what people mean when they're talking about e-bikes; that's usually referring to pedal-assist.

You could, but most e-bikers choose not to go too fast. Additionally, they often have thicker tires and enourage poor aerodynamic body positions which mean that they decelerate faster.

Most are either 60+ or are leisure cyclists. So they just doodle along at their 25km/h.

Proper road racing enthusiasts can average 35km/h including stops (the joys of a flat country).
