I agree with you 100%. I am the same. 25 year old mind in a 62 year old body. I have a Kingsong S22 Pro. I am not worried about it breaking physically as I will only get to about 20% of the loading (if that) of what all the daredevils do, but I do worry when I am doing 50km/h+ that it might just say "goodnight nurse" and drop me face first.
I never buy first run wheels. I have had my eye on the V14 for a while, but it will be a year before I buy one if I do. I sort of think I will stick to 14" rims as you can buy "proper" tyres for them easily and the Lynx looks pretty nice. I know Kingsong and Inmotion (and Veteran?) make better quality wheels than Begode, but I think the reality is that they make less worse quality wheels. I have stripped my S22 down and rebuilt the suspension with new rollers, suspension linkage pins, etc and it's gone from being squeaky and clunky to buttery smooth on the suspension, with a decent (Shinko 241) tyre. I've come to the conclusion that with a lot of these things, the design is good, but the execution is poor.
Don't give up though until you just can't do it any more.
