The 47-year-old mother-of-two moved to the property where the bikes were stolen from at the end of October, and recently replaced the garage door to provide added security for her bikes.
But on Friday morning she began a session on her training bike when she noticed something was amiss.
“I got off my bike to have a look and then realised that the garage window had been forced open with something, and there were shards of wood on the floor,” she said.
One or more intruders appeared to have gained access through the small window and then exited via the garage door with both bikes.
Ms Tucker, who is already in the process of upgrading security at her house with new locks, lights and cameras, called it a scary experience, a “personal invasion of privacy”, and criticised the “pure audacity of invading someone’s house”.
