Mongoose full-suspension mountain bikes, like the Ledge 3.1, have a little bit of height adjustment for the handle bars. See the manual at https://www.mongoose.com/pages/product-manuals . The current link to the appropriate manual is https://p.widencdn.net/brqquy/OMMGFS-1_Mongoose_FullSuspension_OM . Start at page 18 (20 of the manual in the browser) and determine the type of stem on your version of the bike. The quill stem version has minimum insertion marks that must be below the top of the headset and not visible. For the threadless stem version of the mountain bike, you adjust where the handlebars clamp onto the steerer tube. However, this is very imited since there should be only 1/8" to 3/16" gap between the top of the handlebar stem and the steerer (stem) tube. The is where the top cap and bolt to replaced on the handlebar stem and thread into the steerer tube.

I hope this helps.

in the middle of handlebars you will see a hexadon bolt,when you got your new bike the right angle wrench should have been with it if so place the wreanch onto the bolt and turn anticlockwise this will loosen the nut,then pull the handlebars up until the wright is achived make sure they are straight then turn the wrench clockwise until it tightens,.Adrian....

There are typically two allen bolts that mount on the side of the handlebar stem. Those should be tightened. The top one should only be tightened to remove up and down play in the headset. If you tighten the top one too tight, steering will feel clunky. Only tighten the top one tight enough to remove the up/down play. Use the side bolts to keep the handlebars from turning relative to the wheel.

Just loosen the nut on the front of where the handlebars goes through, adjust it the way you want it, and tighten it up.

You haven't given me much to go on, but a common problem is to mis-identify where to tighten. There is a large nut (about 1-1/4 inch) that is the locking nut for the headset (which is where the bearings are that allow the fork to turn and steer the bike). This large nut does not tighten the handlebars. Rather, there is a long bolt that travels straight down through the handlebar stem. The handlebar stem is the bar that clamps to the middle of the handlebars and extends vertically down into the headset. At the bottom of the bolt (where you cannot see it) there is a wedge shaped nut. When you tighten this bolt the wedge nut jams itself inside the tube which is the top of the forks inside the headset, thereby locking the handlebar stem to the the forks. The head of the bolt you need to tighten can have a variety of shapes - could be an ordinary hex head, or it may require an Allen wrench (hex key). There are lots of different styles, but if you Google images of "handlebar stem" you will get the idea. good luck. Al K

THE HANDLE BARS SOUND LIKE THEY ARE THE WRONG CIRCUMFRANCE

well you should try to tighten the bolts first

Check the splines on the handle bar. Just loosen the "clamp" and slide the bar over to one side enough so you can tell if the are stripped or not. If they are then replace the bar, if not then reassemble and try to put a littlle extra torque on the bolt.

I have noticed with the 2 of these bikes that I have that the bars do not like to stay tight for long, they tend to work thier way loose about every other time we use them. I just keep tightening them untill the splines strip, then pick up a new bar.

Good luck.

where the bars slide into forks there should be a allen nut on the top undo this slightly and adjust bar height then tighten up allen nut
