Men’s bike (Eaton, NR4)

My partners carrera bike got stolen in the city which he used to bike to and from work everyday. He has a bike at the moment but it is quite small compared to him (we don’t think it’s a men’s bike) and it is starting to affect his knees biking but he still has to do it for work. Would anyone have a men’s bike that they no longer use or need? He’s quiet bike savvy and don’t mind if it needs some TLC. He will of course post his current one on here afterwards too. Thank you so much❤️
