hi Drossall
Yeah I've tried kiddie-cranks on the old Disco, but for a variety of reasons (not least I just fancy a new one) I wanted a dedicated machine for riding with the kids and same for riding with my missus.
I looked at Co-motion periscope, but their UK dealer never got back to me. They look nice bikes but expensive.
So, I'm looking at a Thorn in L/S size. Not exactly what I originally wanted to do, but the bikes are nice.
