That depends on the model of e-bike. I bought mine about 6 years ago, for $3000 (high quality but still cheaper than $5000 non-ebikes), with a removable battery pack. Remove the battery, and the e-bike can be stored safely just like an ordinary bicycle. I charge the battery pack separately in a safe area, but only to about 80 percent. If fully charged, the e-bike can go up to 100 mile range. The safe thing to do is to charge between 20 and 80 percent.
The problem for college kids, is buying cheap inferior Chinese e-bikes that are susceptible to explosive fires when charging - especially not good if charged in crowded dormitory rooms.
Sounds like you have a very nice bike. Where do you store the battery when you are charging it? Also, concerning college kids, what if a college adopts a rule where there is a specific place they all store their bike’s batteries and charge them while they’re being stored. Looks like another severe fire hazard.
