Why do the majority of people on an ebike ride at a fairly low cadence?

Personally it's because I'm using my ebike to get to work, wearing work clothes (which restrict my pedalling) and not wanting to get too sweaty. If I were just out for a ride I'd pedal faster.

How many watts are lost when pedalling on Bosch e-bike without a motor/electricity?

In theory - none because the motor has a freewheeling clutch that is completely disconnected when it is not providing assistance. That is when you're travelling over 25 km/h (location-dependent) or ...

Why are regenerative brakes uncommon on e-bikes?

Short answer: it's not worthwhile. Most bicycling energy goes toward overcoming wind resistance, especially for casual riders. That energy is lost, with no chance for regeneration. Liberty Trike ...

Why do the majority of people on an ebike ride at a fairly low cadence?

For me, as an occassional ebike rider, it feels I get kind of better connection to the bike when pedaling at lower cadence, but higher force. Because the electric assist otherwise reduces the needed ...

Are electric bike speed limitations set in stone?

The limit is set by law depending on the country. There's nothing to prevent you from going faster if you can pedal harder. The limiter just cuts off the electric assistance above 25km/h, so you'll ...
