Access to second hand equipment

Hello everyone,

I am looking to purchase a tandem bike for my disabled daughter and I. She is 10yo and has mild cerebral palsy spastic diplegia and ASD. I have tried for many years with trikes and bikes but unfortunately although she is physically able to move the pedals she lacks the confidence to keep at it and master the art of riding a bike. When we have been on holiday, she has done really well on a tandem as I think she has increased confidence as we are in it together! I have had a look at the cost of special tandems and they are eye watering expensive!

my question is, does anyone know of any website or organisation offering resale, or the ability to hire such bikes?

thank you
