Litelok Core Plus Bike LockThe Litelok Core Plus ensures maximum security for your electric bike so much so that it's been awarded the highest 'Bicycle Diamond' rating by independent testing organisation Sold Secure. Its 100cm length makes the Core Plus a particularly good lock for e bikes, which are often chunkier than standard bicycles though it also comes in a smaller size (75cm) should you prefer. For such a secure lock, it's also not too heavy, which makes it easy to use
