That’d be your best use of the two machines. Id cycling hurts your knees then I wouldn’t recommend a cycle ergometer.
The NT incline trainer is not the most robust piece of equipment but I will work for home use up to 120KG they say. Scott Semple and I both have these and while they have some minor irritations they function well enough. If you really want a good incline trainer then you need a Woodway but they are 4-5 times the cost of the NT.
