Using torque wrench to tighten bolts

Hi,

I have a 20" electric folding bike - Italwin eLight. I hear a clicky noise when I lean against the handle bar as I I begin to ride, so I need to tighten some bolts, but there are no markings for the nm values at which the bolts are to be tightened. The bike is still under warranty at the bike shop, but it's far and I'm tired of going there to fix this bike, so I think I'd like to do this myself. Right now, I don't have a torque wrench because different models can do different nm values, so I don't know what to buy.

Do the values differ greatly between models?

For almost everything on a bike, a 3/8 drive 20-250 or 300 inch-pound (around 30 Newton-meters) wrench will be sufficient. Park tools has a page on selecting a torque wrench and how to use it with recommended values. Park Tool Co. ParkTool Blog Torque Specifications and Concepts
