Reviews of Sglocks:

"Finally a lock with a hidden punch for
anyone trying to get my bike for free!"
Tough Stuff, Erika Cerri, Birmingham

"Thieves hate noise and I knew if anyone
tried anything they’d be drawing a lot of
unwelcome attention, well done SGLocks!"
Tough Stuff, Nathan Jordan, London

"The alarm is sure to attract attention and
scare away potential thieves. I am sure
this lock will have a similar effect on
reducing bike thefts that the introduction
of the audible car alarm did on car theft."
Street Safe, Michael Cornes,
Elite National Triathlete
