A bike summit to encourage new industries and businesses involved in cycling will be held in South Australia in a bid to grow the economic spin-offs from cycling.

The State Government said cycling could become a $1 billion industry for South Australia within the next few years, encompassing events, tourism, retail and manufacturing.

Manufacturing and Innovation Minister Kyam Maher said bike tourism in the state was flourishing thanks to major evens such as the Tour Down Under.

"While South Australia is already gaining a reputation internationally for cycling, we can benefit even further by supporting industry to take advantage of opportunities that exist in tourism, manufacturing and innovation," he said.

"Globally, more people are opting to cycle for health and environmental reasons because it is often the fastest way to get around cities."

Christian Haag from Bike SA said there has been a cultural shift in Adelaide towards bike riding.

"If we adopt a steady-as-she goes strategy towards transport, then that's a recipe for a city in decline," he said.

"So really I think the policy framework is now very strong in terms of more sustainable active transport.

"We need to see more investment in that area but I think we're heading in the right direction."

Cycling business flourishes in Adelaide

Mr Langeberg said he chose to start his business in Adelaide after attending a previous cycling conference in the city in 2014.

"That allowed us to have a look at Adelaide and what the plans were in terms of cycling infrastructure, and it being an appropriate place for a transport service," he said.

"Things like the terrain, the cycling infrastructure that already exists here and of course the climate for an open-air vehicle such as the one that we use."

The Government said the summit would be held later in the year.
