Best For Scooter: Onguard Great Lock

The onguard great lock's material feels more premium than its price would suggest. The Onguard Mastiff Chain Lock with X4 Padlock is a very big and heavy chain and lock. The chain is long enough that it reaches pretty far if you have to park it kind of far away from whatever you're securing it too. The light on the key is helpful at locating the mechanism at night. Even with an angle grinder it'll take a while for anyone to get through this chain.

The chain is well made and the lock is solidly constructed. It offers optimum resistance against physical attack and picking. The chain is very thick and sturdy. It's a bit heavy to wear while riding.

Best For motorcycle: Onguard disc Lock

Buy on Amazon

This lock is higher quality, better built, and cheaper than the kryptonite chain locks. It is a short shackle boxer u-lock paired to a 3.5ft long, 10mm hardened steel hexagonal link chain. It is reinforced with titanium and the boxer u-lock can also be used alone as a disc lock. It also is super heavy and you have to be careful what it bangs in to since it's not covered like the chain. It is also long enough to put through both wheels and the back triangle and to something.

It comes with this lock, no bike thief is ever gonna steal your bike.

Best For Locking up Bike: Onguard Mastiff Chain Lock

Buy on Amazon

Next on the list, we've got yet another product that manages to win our hearts. It's the onguard mastiff chain lock and it's widely considered as one of the best convenient products you can buy. It can be quite the overkill in safer places. It is one heavy duty chain and it is heavy. The large end link (noose) enables one to lock up both wheels/frame to a bicycle rack without needing an even longer and heavier chain. This allows you to get a much greater usable length out of a chain, since you can loop the chain around an object and just U-Lock to the frame. It covers the length/conformation is great and the lock is fantastic.

The only practical way to defeat this lock in a reasonable time should be power tools, like an angle grinder.
