Cyclescheme

Thats not 'cyclescheme' it is a specific wiggle set up
My understanding is that Cyclescheme is just a scheme administrator. Any employer could, in principle, do salary sacrifice purchase of bikes for its employees without cyclescheme or wiggle or anyone else. They are just facilitators.

It worked really well for me. At least with this scheme you can go to real bike shops. Previous one where I worked meant you had to go to Halfords. You can imagine how popular that one was.
