There are two categories — purpose-built cargo bike covers and large motorcycle covers that happen to fit.
Bike Parka makes high-quality covers built specifically for cargo bikes. They're designed to fit the geometry of front-loaders and longtails properly, with good weatherproofing and coverage where it counts. Worth the investment if your bike lives outside regularly.
For the Urban Arrow specifically, the Favoto 104-inch motorcycle cover fits well and is significantly cheaper. Good option if you want solid weather protection without the premium price.
For the Aventon Abound LR: [cover recommendation coming soon]
Many NYC cargo bike riders "claim" a street sign near their building and leave a heavy-duty lock there permanently — so the bike goes straight to a dedicated anchor point every night. Use two locks minimum. A well-lit, visible spot on a busy block is meaningfully safer than a quiet side street.
A GPS tracker adds another layer. See our guide: Registering and tracking your cargo bike →
Strongly recommended for bikes stored outside overnight. Check your renter's or homeowner's policy first — some cover bikes up to a certain value. Velosurance offers cargo e-bike specific policies with theft coverage if you need more.
