I need one, I think. I will soon have 3 kids and this means I will not get to the gym for ages (I honestly know what I am like here). But also I go nuts without exercise. And I will save enough in gym fees to buy an okish bike.
So.
What do I need to know?
Would it work to just buy one of those very cheap, basic Tescos ones, plus a heart rate monitor?
Is there such a thing as a decent quality folding bike?
Any more thoughts?
