Cargo Bikes

Pragmasis is the brand everyone rates. They're expensive so any Sold secure GOLD lock will be much of a muchness when it comes to deterring thieves, and as long as it ticks your insurance box.

I'd highly recommend getting some sort of GPS tracker too, particularly if you have an ebike.

I got this and also carry a couple of d-locks and a chain that connects to a front wheel cafe lock.

The litelock isn't as flexible as I was expecting, but Sold Secure Diamond and waaaaay lighter than a big motor cycle chain. Tricky to store but mine hangs inside the stormbox on my GSD from one of the rails.

@rwn as @MCamb said. Get a motorcycle chain style lock and make sure you use it and lock the bike to something immovable. I still see so many expensive cargo bikes just locked using the Dutch style rear wheel locks! :O

We cut the legs off an old wetsuit and use that to store the lock in to prevent too much rattling around, but we can stash it behind the kids seat so it doesn't move much.

Also got a pitlock on the front wheel to save us securing that with an additional lock. We have a dynohub so don't want that getting stolen as it's more £'s!

what do people reckon the best locks are for a cargo bike?

I have:

1. a D1000 Hiplok - https://hiplok.com/product/hiplok-d1000-anti-angle-grinder-bike-lock-waitlist/
   
2. a Kryptonite NEW YORK FAHGETTABOUDIT CHAIN 1415 - https://www.kryptonitelock.com/en/products/product-information/current-key/999492.html
   
3. a Monimoto Tracker - https://monimoto.com/uk/shop/
   
4. Insurance
   
   

Still feels like it isn't sufficient in London!
