The EU Commission says [0] 3km is the average bike trip length in most European countries. They reference this other EU funded study [1] on replacing short car trips with walking and cycling, which says:

> The willingness to cycle over longer distances differs between countries, but in general we should not expect people to use a bike for transport on distances longer than 3-5 km.

Both are from before the e-bike boom. A 2019 Dutch study [2] says the average e-bike commute trip is ~8.5km, which indicates a rough doubling of the conventional bike range from 3-5km to 6-8km. Notably, commutes are significantly longer than all other ride types in the Dutch study, even with e-bikes.

Also in NL I feel like 10km (one way) is already more than most people are willing to cycle daily.
