Mate has asked me to look over his 2 bikes- an unused Brompton and a very well used Bike Friday Tikit – both sat in his garage for years after leaving uni – apart from usual stuff etc anything I should look at – just wants thrum relatively ship shape for commuting –

I’ve never really looked at folding bikes up close before, they’re pretty cool

Check the chain wear. And the hinges on the tikit. Might needs some new cables for smooth operation. Otherwise not much else to go wrong.
