The Raleigh m20 Mountain Bike is a hybrid Mountain Bike. Troubleshooting is fairly straightforward due to the commonality of the bicycle.
Loose/Damaged Rear Rack
The rear rack is loose or damaged.
Loose Top Screws
If your rear rack is loose, you need to tighten the top screws. Use your hand and level the rear rack. Once it is level with the tire, use a philips screw driver to tighten the screws on top of the rear rack.
Damage Rear Rack
If your rear rack is damage, you may want to replace it. Refer to the Rear Rack Installation Guide for information on how to remove the old rear rack and install a new one.
Your handlebars aren't centered or are bent out of place.
Turned Handlebar Stem
If your handlebars are out of alignment with the front wheel, (not physically bent), loosen the stem bolt. Then straighten the bars to the front wheel and re-tighten the stem bolt securely.
Bent Aluminum Handlebars
If the aluminum handles bars bend slightly, try to straighten them yourself with a vice or grip. Keep an eye on the area near the bar clamps because if they break that would be the place where stress risers would develop. If the bend is beyond repair, replace with a new set of handlebars using the Handlebar Repair Guide.
Bent Steel Handlebars
Unlike aluminum handlebars, steel handlebars cannot be bent back into place. This issue requires referring to the Handlebar Repair Guide.
