Help me choose an exercise bike?

I have had 2 exercise bikes in recent months..

this model:

The handlebars sheared off as the welding was poor quality

and this model:

Which I have had less than a week and is being returned for refund on monday as it is terrible quality and the pedals are very clunky when they turn.

Up until these recent problems I have been doing about 10 miles, 4 or 5 times a week, and my hubby uses it too, so I need something fairly sturdy.

I have been recommended these models:
