Cargo e-bikes are expensive — $2,000 to $10,000 is a normal range. Thieves in NYC know this, and cargo bikes are sometimes targeted because their higher value makes the effort worthwhile. A $30 cable lock that might be fine for a beater bike is essentially no lock at all for a cargo e-bike.
NYC has one of the highest bike theft rates in the country. The combination of high bike density, accessible public spaces, and a resale market for parts means that an unlocked or poorly locked bike can disappear quickly. Quality locks are not optional — they are a core part of ownership.
A U-lock should be your primary lock. The hardened steel shackle resists cutting, and the rigid design gives thieves very little room to work with a jack or pry bar.
A chain is your secondary lock. It covers what the U-lock can't — your front wheel, cargo box frame, or a second fixed point. Chains are heavier but more flexible, letting you secure awkward shapes.
A common rule of thumb is to spend 10% of the bike's value on security. On a $5,000 bike, that's $500. In practice, most NYC cargo bike families spend $150–250 on locks and get insurance in case your bike gets stolen. That gets you a solid U-lock and a decent chain — good protection that deters most thieves.
If you leave the bike outside regularly or in a high-theft neighborhood, consider two heavy locks plus a GPS tracker. If the bike lives in a building bike room and only goes out for daytime use, a single premium U-lock plus a chain should be okay.
Both Kryptonite and Abus offer key replacement programs — if you lose your key, they'll send you a new one if you registered when you bought the lock. Do this immediately. It takes two minutes and saves a locksmith call later. Also register your bike with the NYPD. See our guide: How to register your bike with the NYPD →
