"We just love cycling on the three-seater and we would like to share the fun with more people," said Dr Steane.
Successful bidders can cycle for a few hours or a few minutes, depending on their preference. They can even ask to be dropped at work or catch a lift to a local cafe if it roughly fits in with the route the cyclists are planning.
Dr Steane spotted the three-seater for sale in February and decided the best way to get it from its former Auckland location to its new home in Christchurch was to cycle.
The Trade Me auction for the third seat through Wairarapa closes at 8pm tomorrow and can be found by searching for "Threeseater" on www.Trade Me.co.nz.
