I carry a "missing link" and small chain link removal tool with me in a little pouch attached to my bike so that I can be ready for a chain break (also a spare tyre tube and tyre removal tools). My e-bike _really_ likes to eat chains. I've had it for 2 years and I'm on my third chain now. I don't do anything fancy, just ride it for 7km on pretty flat bike paths twice a day for around half the working year (so I'd estimate I've done ~2100km on it so far).
