Heavy Rider Option is available on the Bike Friday Pocket Llama.. I own one.
But , in General, think Metal fatigue .. heavy will = a shorter time before if weakens .
hard use also shortens the usable life span, of course.
so keep a more careful eye on the inspections for signs of fatigue, then replace..
