I had this same problem once with a bollard and thought, “maybe that’ll trick a crackhead.” To avoid a fail, I then U-locked the front wheel, unplugged the Stokemonkey, and toe-strapped the front brake. If the cable-around-the-bollard trick didn’t fool the crackhead, he’d surely not get far with the front brake on.
Sometimes I’ll also just pull right into a parking slot, and immobilize the bike, as noted above.
What are your locking techniques for a cargo bike? I know Val figures that his Dreadnaught is so intimidating few would consider stealing it and if they do, it isn’t going far with the brakes locked.
