Question about Cycling
The bars feel still and makes a cranking noise when moved, I think the bearing have gone but not sure how to remove them from new bikes.
I don't know what type of bicycle you have, or how modern it is, but the handlebar and steering head are similar on most models. Try to remove the handlebars and steering head from the bike as a unit. There is a large nut at the top of the head tube (where the steering stem goes into). Loosen this nut, and the handlebars and steering stem should pull up and out of the bearing inner races. When you completely remove that nut, the headset will come apart... (including the fork and front tire which will drop out of the headset. If your brake and shifting cables are too short to let you pull the steering stem completely out of the steering head, you'll need to remove the handlebars from the steering stem. If you are careful, the bearing set, spacers and washer will stay on the fork tube when it comes out of the bicycle frame head, so you will know which order to reassemble them in. Either tag them or lay them in the proper order. Now you can clean the bearings or replace them.
It would be a good idea to clean the bearing races at the top and bottom of the steering head too.
Once everything is cleaned and ready to reassemble, grease the bearings and the bearing races and reassemble. When you tighten the stem nut down, make sure that there is no play between the steering head and the steering stem.

You wil need a couple of special tools, or be fairly creative with the tools you have.
to assemble, reverse above procedure, insuring bearing play is minimalized.
Hope this helps.

This isn't Bike Repair 101-level stuff. Take it to a reputable bike shop and have them teach you while they do it. If they're cartridge bearings it's fairly simple. Next time, you can handle it. Be advised, crankset removal tools are specialized and expensive for the casual bike owner who would use them only once every few years..

Testimonial: "After more investigation, I strongly agree!"
Take it to a professional bike shop. They have the knowledge and tools to set it right.
Or take a look at this:
The headset nuts were not necessary to be moved for handlebar adjustment. Now the bearing load is too tight. Correct adjustment of the headset requires a delicate balance between tightness and freedom of movement. If your bike has/had the original bearings it's a safe bet they may be due for replacement anyway.
