Overall I quite enjoyed this special episode and there were some really good ideas on display. I do hope that the free screen reader catches on, a lot of thought went into that.
One thing that disappointed me about the unique factors segment was that the manufacturer of the lean steered trike was not identified or referred to. If, as I suspect*, it was Greenspeed this is particularly disappointing.
This is not Greenspeed's first entry into access/ability cycling. Leaving aside the obvious attraction of trikes to those with balance/co-ordination issues, Greenspeed have been producing a hand cranked version for several years.
*The shape of the frame, and the layout of the steering mechanisms underneath seemed fairly typical for a GT, and it looked like it had 16" wheels.
