Designed in the 1930s by Jumbo bicycle parts in Ede, The Netherlands, Jumbo is the most iconic bicycle pump in the world. In the early 1970s the Jumbo plant closed, and production was taken over by Presikhaaf, a social employment facility to help people with a disability reintegrate with society. The Jumbo pump is durable and parts can easily be replaced. Presikhaaf makes 80.000 pumps per year and has sold over 5 million pumps already.
