How do you secure the battery with ulock? Or are there bikes with non-replaceble batteries? How do you charge them?

The VanMoof has built-in batteries that are extremely hard to access. You must take the bike near an outlet to charge.

Unrelated to VanMoof, my bike has a battery that goes on top of the rack. The battery includes a key, and locks to the bike. To charge it, I usually just leave it on the bike, but you can fairly easily unlock it from the bike and change it separately if desired.

If I had an e-bike I would just take the battery with me. Minor inconvenience for security.
