We get all sorts here
@wafter . From Chinese basic bikes to racers and mountain bikes which are the most popular due to the poor roads. Most are what is know as "home used" in other words sent from abroad, these are the most valued, even parts, you'll pay more for a home used chain than new Chinese one, same with tyres and most else. They come from Europe, the US and UK. There's one street in Accra that is lined with just bike sellers, haven for vintage bikes as well as newer ones.
I bought a nice Specialized AWOL adventure bike a couple of years back for little money which is my main bike. I've also got a Schwinn eighties racer and a nice 2007 aluminium frames Trek I rescued which you can see in this section.
There's no domestic manufacturers apart from some bamboo frame bikes.
Decathlon have a shop here but prices are higher than in UK but you can get most new bike spares which is useful.
