For the best defence against angle-grinder attacks, you need a Hiplok DXL1000. 
It's part of our Anti-Angle Grinder 1000 Series - there's nothing else like this on the market.

It's at least 20 x more resistant than standard D locks, and multiple tests prove it.

You can fit your DX1000 to most large bicycles, e-bikes & motorcycles, 
with a locking area 205mm x 112mm (L x W). At just 2.6kg, 
the DXL1000 is still one of the lightest Sold Secure Diamond rated motorcycle D locks around!
