The Speedshop | Preview (BBC Two)

An ex-Special Forces colleague and close friend of Titch needs his help. Toby was shot while on ops in Afghanistan and is now paralysed from the neck down, requiring a mechanical ventilator to breathe.

However, he has a burning desire to experience his pre-injury passion for riding motorbikes. Titch and Toby hatch a plan to create an adapted sidecar that can hold Toby securely and house his life-preserving ventilator system. The pressure of

getting this build absolutely right is self-evident - there is no margin for error.

To relieve the pressure of the sidecar build and boost morale among the team, Titch devises an in-house competition, the Drill Bike Derby. The challenge is for each of the team to build an electric bicycle powered by a cordless drill. Their creations will then go head-to-head in a race to find out who’s machine is the fastest.

The victor of the inaugural Drill Bike Derby will win the heady prize of not having to make the teas for a month!

The Speedshop returns Sunday 20th March at 8pm on BBC Two.
