Hi @mynameisluka
As someone who used to be a local at Wolwespruit and enjoys more gravity bases riding here are my 2 cents (it ended up more like 2 rands in the end😅)...
Off the bat: HT (More specifically a rowdy trail HT 😁) all the way if you are starting out!
I will state my case as follows (apologies if you already knew some of this stuff) 😜
1. Riding location NOTHING at Wolwe or Grootfontein is unrideable on a HT. I did it myself for a long time. In fact most of the stuff you will likely end up riding are flow trails where a HT can actually be more fun because it is more efficient to pump (more on that later😁). For these locations though, I will suggest a trail HT and NOT an XC anything. Both Wolwe and Grootfontein have some proper jumps that as a beginner you might end up casing a few times. You don't want to be concerned about your bike's health the whole time. A light XC hardtail is built to be light and pedal easy NOT neccesarily to handle big impacts.
In conclusion here, buy the bike for the trails you are GOING to ride 95% of the time not for the ones you MIGHT ride 5% of the time.
2. Price Mentioned before a couple of times in this thread a HT is quite a bit cheaper to maintain than a fully. Like @droo has mentiined, pivot bearings and rear suspension services don't come cheap unfortunately.
Spending less money on your bikes also frees up some to spend on something else no-one I have seen has mentioned before. GET SOME LESSONS! Which brings me to point 3...
3. Easier to learn on HT don't change their frame shap subtly when you manipulate the bike into a wheelie, manual or bunnyhop. This means it is easier to learn these skills on a HT and turn them into second nature (again go for lessons from the start).
Learning to pump the bike is also easier because you get more direct feedback and results.
Lastly a HT teaches you to move on the bike, so you need to learn to use the suspension in your legs to squash and pump the trail. If you can make this second nature, when you do move tot a fully, you will actually get your money's worth.
@Jono also alluded to this earlier. Learning proper skills early on will make your riding so much more fun and a whole lot safer.
ending off...
So my suggestion would be have a look at the rapide tigre frame. Really good proper steel frame at a very good price. https://www.rapide.co.za/ offer some of the best service you will find anywhere and it's alocal company. Their stuff is also affordable and tough enough to last you quite a while. Their wheels are also great value!
Then get a dropper post (PLEASE don't start riding without one) and other components (get amp series of you can) from https://www.on-lynecomponents.com/.
Again solid reputable local company.
Fork, I suggest a DVO diamond. DVO is travel adjustable which means you can keep the fork of you change to a fully frame at some point.
Drivetrain: Shimano linkglide 10s. Dirt cheap and really solid (I just put the M5130 shifter and derailleur and the LG400 cassette on my bike and really happy so far, entire groupset was cheaper than the freehub body I had to replace to fit the cassette.)
Brakes: hydraulic disc brakes (4 pot if you can) with 180mm rotors (203mm at the front if you are a bit heavier). Honestly brakes are a personal thing but starting out, Shimano is cheap and will stop.
Lastly if possible, try to build the bike yourself. Knowing how to do the basic bike maintenance will save you a lot of money and time in the long run.
If you got to the end of this essay, I hope it was useful to you in some way and may you have a kick-ass time on whichever bike you choose!
Please feel free to drop me a DM if you want any more advice or some contact info for lessons (and no, it won't be from me😅)
