As a fellow Clydesdale rider (128kg), I can empathize with you when it comes to bicycle industry parts failing prematurely. Fortunately, there are at least three direct drive trainers that will hold up to the weight and power of bigger cyclists.
I have personally ridden 5,000+ miles in the past 14 months on a Tacx Flux S without any issues. I have a friend @110kg that has 2,000+ miles over the past 8 months on this same trainer, also trouble free.
I also ride on a Saris Hammer H3 at work, as do a couple of co-workers. One of my co-workers is 118kg and the H3 is working great with 3,000+ miles in the past year.
The third trainer that I’m confident will hold up to heavier/stronger riders, is the Tacx Neo. This has been ridden 8,000+ miles by a very powerful 108kg racer (4w/kg) without a single problem.
All of these trainers have held up to thousands of out of saddle sprints between 800-1,500W, hundreds of 2-4hr workouts, along with multitudes of hour long threshold grinds up the Alpe, Epic KOM and Innsbruck climbs.
I definitely recommend you make sure the frame dropouts are fully seated on the trainer axle and the skewer is properly tightened. It is also worth checking this connection weekly, along with cleaning and lubing the chain.
Hopefully this info helps you in your quest to get for, lose weight and stay healthy.
Have fun and ride on!
