Keep your bike safe with 6 of the best locks from Squire

Toughness guaranteed! The best Squire locks for locking your bike at home, plus 10 top tips for keeping your bike safe

With a range of more than 80 different products, and a tradition of lock making that has been passed down father-to-son through eight generations, your bike is in no better hands than when it’s protected by a Squire lock.

From humble beginnings in the late 18th century with a small selection of padlocks, door locks and cabinet locks, to the first lever padlocks in the 1800s, to a breakthrough range of dedicated bike locks in the 1963, Squire has constantly innovated and developed to make sure your property is ever more secure. That approach continues today, particularly with products that offer ultimate protection for bikes at home.

Of course, there is a temptation among cyclists to think that if their bike is in their house - or garage or shed - it’s safe. But that’s far from the truth. Garage and outbuilding doors are particularly easy for thieves to open, and once they’ve broken through that, your bike is easy pickings. Insurance companies know this, too. You may find that, should the worst happen, your insurance policy won’t cover you for a stolen bike even from your own property, unless it’s suitably locked up.

So that is why Squire’s range is so important for cyclists. With the Sold Secure standard you not only get awesome security for your bike, you also get peace of mind that the products you are using will conform with the requirements of your insurance policy. And with Squire’s ‘Toughness Guarantee’, you also get a personal 10-year no-quibble guarantee from John Squire on all Squires locks – you don’t even need a receipt.

So how should you keep you bike safe and sound? Before we look at the options from Squire, here's some general advice...

10 tips to keep your bike safe at home

  1. Keep your bike or bikes away from windows and out of sight
  2. Choose something solid, secure and immovable to lock them to – a wall or floor anchor is a good idea
  3. Use two different types of lock – having to think twice will help to deter would-be thieves
  4. Use the very best locks you can afford – these will stay at home, so there’s no need to worry about weight. Consider spending 5-10% of the value of the bike on locks and ground anchors. If you’ve got a £8,000 e-bike, a £15 entry-level cable lock isn’t going to buy you much time against a professional thief 
  5. Feed one lock through the front wheel and the main triangle of the frame
  6. Feed the second lock through the rear wheel and the main triangle of the frame
  7. Try to make the locks fit as tightly to the bike as possible to reduce the amount of ‘wiggle room’ where thieves can use tools
  8. Put up a sign or use a sticker to warn would-be thieves that your bike is registered and trackable
  9. Make sure the lock isn’t resting on the floor as the floor can be used to gain extra leverage when using bolt cutters, or as a solid base when using a sledge hammer
  10. If you have your bike locked up in the shed, get as good a hasp and staple as you can afford. We recommend Secured By Design products. Plus, you must change the hinge screws over to security screws so the door can’t easily be removed on its hinge side.

Sold secure – what it means

Sold Secure is a not-for-profit organisation to which manufacturers can apply to have their products independently tested and verified. It was established in 1992 by Northumbria and Essex Police with the backing of the Home Office, and is now owned and administered by the Master Locksmiths Association. 

Sold Secure approval is classified into three main categories; Bronze, Silver and Gold. The categories reflect the amount of time it takes to overcome the lock, and the tools required to do it. The higher the grading (Bronze is the lowest), the higher the security provided by the product. Many insurance policies require that bikes are secured with Sold Secure Gold locks.
