Build to Bond: bikes built by fathers, ridden by their children

At HMP Lowdham Grange, men learn to build a bamboo bicycle by hand — and many build a balance bike for a child waiting for them at home.

The idea

Lowdham Grange is a Category B men's prison in Nottinghamshire. Inside it, Bamboo Bicycle Club runs Build to Bond: a course where Makers learn to build a bicycle frame from scratch and earn a recognised qualification while they do it. The bike that comes out the other end is often a small balance bike, made by a father for his child — something to hand over on a visit, or to be there waiting when he gets out.

We use "Makers" deliberately. The point of the programme is to treat the people on it as people who make things.

What we do

The course runs over six weeks, at eighteen hours a week. Makers start with basic joints and work up to a complete frame, using bamboo and hand tools suited to a workshop environment. It is delivered in a dedicated 2,000 sq ft workshop on site, and it carries OCN London Level 2 accreditation in sustainable manufacturing — a qualification Makers can carry out of the gate and into work.

It has been running since late 2024 and is oversubscribed: more men want a place than we can take. Three Makers from earlier cohorts have gone on to train as peer instructors, helping to teach the men who came after them.

What it has done

Every Maker who has started the course at Lowdham Grange has completed it. Programme evaluation has measured a 26% uplift in confidence. An independent impact assessment puts the social return at £11.41 for every £1 invested.

One of the balance bikes built on the programme is on display at the National Justice Museum in Nottingham, where it has been shown for a year — a bike made inside, exhibited as a piece of justice history.

The wider context is well established: Ministry of Justice research links maintained family contact to a 39% reduction in reoffending. That figure is the MoJ's, not ours — but it is exactly the kind of contact a bike built for a child is meant to keep alive.

In their words

Lord Timpson, the UK Prisons Minister, has publicly backed the programme:

"Innovative projects, such as Build to Bond, support rehabilitation and help people leave prison as better citizens, boosting the economy and keeping our streets safe."

Why it matters

A prison course that ends in a qualification is useful. One that ends in a bicycle a man made for his own child is something else — a reason to finish, and a thread back to a family. That is the whole idea of Build to Bond, and it is why we want to take it to more prisons.
