If you enjoy doing bike mechanics in the workshop and also doing tech posts you should give it a try and see how it goes, cause you have the knowledge and for mechanics video is better I think. But after following you for a while I also really believe you are a very talented writer with good humor and excellent English skills and overall a really good story teller, it's one of your natural strengths. Experiment and see what's best for you my friend, you will learn a lot in the process.
