Find it yourself lazy!
the wheels spin slower than usuall, or they dont spin very smoothly
The answer is WD-40. It really improves your bearings. This answer is from James P.
Cars have a total of four wheel bearings, one on each wheel. The wheel bearings are designed to help the wheels spin. Many cars have two wheel bearings per wheel, an inner and an outer located in each hub/bearing assembly.
It's the part that helps the wheel spin, also commonly called the bearings.
It is the a part that gosse in the hole of the wheel and makes it spin longer and faster there are diffrent types of bearings and abec is a raiting used and also abec 3 bearings can be faster than abec 5s it really doesnt make a difference its mainly its durrability
Little metal balls that help the wheel spin. The best ones are Reds Dragon
The purpose of an axle cone in a bicycle wheel is to provide a smooth surface for the bearings to rotate on, allowing the wheel to spin freely and smoothly.
Same way as any gear set does. If you have a large wheel(more teeth) driving a smaller wheel(fewer teeth), then the smaller wheel will spin faster, but with less force. If you have a small wheel driving a big wheel, then the big wheel will spin slower but stronger.
To properly grease your bike wheel bearings, first remove the wheel from the bike. Then, use a degreaser to clean the bearings and remove any old grease. Apply a small amount of high-quality grease to the bearings, making sure they are evenly coated. Reassemble the wheel and spin it to distribute the grease. Finally, check for any excess grease and wipe it off. This will help ensure smooth and efficient performance of your bike wheel bearings.
This could be a result of the bolt on the wheel being too tight. try to loosen the bolt just a little bit. Too much friction will cause the wheel to spin slower, and too little friction will cause it to spin too freely. if this doesnt help, try to ride them for a while, and break them in.
Ball bearings reduce friction by allowing the wheel to rotate around an axle smoothly. The bearings distribute the load evenly, reducing the amount of friction between the moving parts, which helps the wheel spin freely and with less resistance.
Make sure the nut that holds the bearing in place is properly adjusted.When you tighten it the wheel should spin free but you should no be able to wiggle it.
