I know many in SA are considering emigrating. I used to live in Randburg, but have now emigrated to West Yorkshire, UK.
My experience of cycling here is as follows:
Cycling is a BIG sport here in the UK. Everywhere you go, you see cyclists.
Whereas in SA, I used to ride 90% MTB, here I do 99% road. That is because where I am based, the road cycling is simply amazing, and MTB riding is not quite as accessible funnily enough. There are MANY walking trails everywhere, but many of them specifically say "No cycling" for some reason. I've also joined up with a bunch of guys who mostly road ride here so that's what I tend to do.
I find cycling gear here is cheaper than SA. There are lots of great online stores and especially if you are prepared to buy on sales etc, you can get great stuff for big discounts. Obviously with the pandemic, certain items are hard to get and hence not cheap. Cool thing is that when you buy something online, it typically arrives within about 48 hours or less.
The drivers here are largely WAY better than SA in terms of giving you a few inches of space! I am NOT saying it's perfect and I believe much of Europe is much better in terms of respect for cyclists, but I have found the UK to be mostly good. However, there IS a anti-cyclist brigade and a few a-holes that rev their cars as they go by or hoot if you so much as dare to be on the road!
I am riding here a lot more than SA. It's so easy to pop out, particularly on a summer evening and do a ride from 8 to 9.30pm! Obviously we are now heading into winter so that's changing but I still love that. In winter, it can of course be $£$& cold but you buy the gear and get on with it.
Anyway, here are a few recent photos of my cycling trips. That 2nd photo below is a hill called "Park Rash" with a gradient that reaches 25% at places! Lots of steep hills around here. Had to put on an 11-34 to cope!
