Clamping the clamp
Once you have dealt with compression, you need to put the steering wheel back. After that, tighten the clamp, as this can also cause backlash on the steering wheel of the scooter. With frequent use of the vehicle during a certain period, the bolts and nuts in the clamp begin to loosen gradually. The result is steering play.
A similar problem can form on brand new vehicles. Therefore, it is necessary to clamp the clamp from time to time to avoid such problems. It is advisable to check the bolted connections before each ride. It takes a little time, while you can absolutely safely hit the road.
If the front propeller fork is spinning
If you are faced with this problem, when on a scooter with a front shock absorber, the lower part of the fork with a wheel is scrolling, and not the tube of the handlebar itself, more complex repairs will have to be performed.
Complete disassembly of the steering section will be required. In some cases, when severe wear of the unit is noted, it is necessary to replace a special adapter or bolt, due to which the shock absorber is fixed.

Before proceeding directly to the elimination of the steering column malfunction, you must finally make sure that the problem lies precisely in the backlash of the steering wheel. To do this, you need to fix the vehicle using a footboard, while placing a stone under it. After that, you need to slightly raise the front wheel and grab the bottom edge of the fork. Next, you need to scroll the propeller in different directions. In the event that the wheel does not wobble during such manipulations, the steering column on the scooter is in good condition. However, if backlash is still observed, it will be necessary to eliminate the malfunction.

Why does the scooter have a dangling and spinning wheel, and what to do about it?
Due to the steering column, the reaction of the front propeller to the actions of the steering wheel is carried out. As a result, the wheel is transferred from the steering wheel, after which the vehicle turns in a given direction, or performs any other maneuvers. Each unit has its own control system, even for a children‘s scooter. Some are equipped with bulk bearings, while in others they are placed in a special cage.
Compression system check
If you are faced with such a problem as the appearance of a scooter backlash, initially you should carefully check the compression system. To this end, you will need to loosen the clamp, and then remove the steering wheel. If the city scooter has a threaded connection, you need to check the nuts and locknuts, how well they are tightened. If a different type of compression is installed on the adult scooter, you have to tighten it as carefully as possible using a hexagon. In the process of work, you should not squeeze too much, however, it is also necessary to avoid backlash.
How to reduce the backlash of a scooter
In the presence of the slightest wear, the rider will have to get acquainted with such a malfunction as steering play or jamming.
The scooter, although not a complex structure, still needs maintenance from time to time. In order to prevent problems with the steering column and the formation of backlash, you should periodically inspect the unit.
You should also take into account that when it comes to stunt scooters. it is better to entrust the service to specialists if you do not have the proper skills in the field of repair, since a more serious load is imposed on such models during operation.
If there is a problem with the rear ratchet
The ratchet can malfunction if there is too much oil used to lubricate the ratchet, or, conversely, if there is no lubricant in this part of the bike. The ratchet bearings may even crumble or begin to stick. In any case, you will need to remove the ratchet and carefully inspect it. if necessary, replace the bearings, clean the parts from dirt and dust with special fluids, lubricate everything thoroughly. these simple manipulations can already eliminate pedal spin.
Honor should look at it under good lighting before disassembling the ratchet and lubricating it. you can immediately see how dirty the parts are and whether there is oil there. In this case, no disassembly / cleaning / lubrication work is necessary. look for another cause of the problem in question.
If the cranks of the bicycle sprocket are worn out
In general, problems with an asterisk can be detected with the naked eye without proper experience. First of all, you need to pay attention to the force with which you have to press on the pedals while driving. if you need to make tangible efforts, then the problem is in the sprocket. And this leads not only to scrolling the pedals, but also to stretching the chain, and then there is only one way out. to completely replace the bicycle chain with a new one.
There are 2 more options:
- The sprocket is simply “worn out” (licked off). this happens when the bike is used for a long time and in the absence of proper maintenance of the vehicle. With this problem, poor grip is observed, which provokes pedaling.
- The sprocket is too dirty. you will have to thoroughly clean it with special liquids or fine-grained sandpaper.
If there is a problem with a worn out asterisk, then you need to do the following:
- remove the rear sprocket;
- disassemble the asterisk;
- if necessary, replace parts with new ones or sharpen the sprocket teeth.
Note: experienced cyclists recommend a complete replacement of the drive mechanism and have it done in a specialized workshop.
The pedals on the bike are spinning. the reasons and methods of fixing the problem
Bicycle pedaling is a common problem faced by every owner of this two-wheeled vehicle. The reason for this condition can be both worn out parts of the bicycle and improper care of the vehicle. This article will discuss the most likely causes of pedaling on a bike and how to solve the problem.
If there are problems with the transmission
Experienced experts believe that when scrolling the pedals, first of all, you need to pay attention to the transmission. it must be cleaned and thoroughly lubricated with special agents. Particular attention should be paid to the sprockets and the inter-roller space of the chain. To remove the chain for processing, you will have to dismantle the wheel.
If, even after cleaning the transmission, the pedaling problem persists, then it is advisable to completely replace the entire set.
You can repair or replace the rear hub. this will be a cardinal solution to the problem in question. We act as follows:
Note: some “craftsmen” give the cone for processing on a lathe. This approach to solving the problem can delay the cranking of the pedals, but sooner or later you will have to replace the rear hub kit anyway.
Pedal scrolling may occur due to a lack of bearings in the hub. To verify this, you need to disassemble. If there are not enough steel balls, add the required amount.
Be careful when disassembling the bushing as the bearings may spill out. While the mechanism is disassembled, you can clean and lubricate all components.
Assessment of the general condition of the bike
If the pedals on the bike are scrolling, before moving on to disassembling its components and thinking about repairs, it is worth assessing the general condition of the bike. First of all, you need to check how correctly the rear and
front derailleurs are set, which are responsible for changing the speeds. A failure in the settings will be indicated by an uncharacteristic annoying crackle while driving, as well as a fairly regular hit of the chain between the sprockets when pedaling.
Sometimes the problem affects bikes that do not have a gearshift system installed. In cases where the pedals on a bicycle of a similar plan are scrolled, first of all, you should pay attention to the condition of the chain. It may just take a thorough cleaning and lubrication to fix the trouble.
Why pedals are spinning idle
- increase in free wheeling;
- weak spinning of the wheel;
- chain slippage in motion.
If a malfunction is detected, there is a keen desire to check the pedals, more precisely, the drive connecting rod-pedal mechanism. Some of the scrolling is due to the carriage, but often the reasons lie elsewhere in the drivetrain:
- rear wheel hub;
- sprocket system. cassette or ratchet;
- chain and chainrings.
The first reason is common for road bikes, mountain bikes, and single-speed bikes with hub-drum brakes. With long-term operation, the inner components of the bushing wear out, lose engagement with each other, due to which the torque from the sprocket is not transmitted to the bushing. As a result, the cyclist pedals only the stars, but not the wheel itself.
The pedals rotate completely, and the wheel does not rotate. a neglected case when the hub fails. But most often there is an increase in free travel, the bike gets under way harder, and slippage appears on the move.
Cassettes and ratchets are parts for high-speed bikes. Complete wear on cranks and bearings can cause chain slippage and idle pedaling. Other reasons are partial wear, dirty sprockets, too much or no lubrication.
The chain is the same on singlespeeds and speed bikes, so wear and / or dirt can cause the pedals to crank here and there. In the extended state, the chain hooks on the teeth of the stars worse, slipping over them. Ranges of total link length:
- 304.8. 306.4 mm. normal chain;
- 306.4. 308 mm. Average chain wear. May affect the transmission of torque, single pedal clicks are possible.
- 308 mm and more. the chain is worn out, causes wear on the stars, slips and flies.
Worn chain sprockets, coupled with a worn chain, can also increase pedal cranking and bouncing. Although the problem may arise due to accumulated dirt.
Incorrect speed change setting
The last reason is the wrong bike speed setting.
This is due to the fact that the shifting foot does not reach the required sprocket:
- To solve this problem, you first need to check the cable and clean it of dust and other debris, if any.
- After that, you need to re-configure the gearshift system on the bike.
- Having done all this, you need to conduct a test ride on a bike.
- If the connecting rod-pedal group no longer scrolls, then the problem was precisely in this.
- If no changes have been made, the rest of the bike components must be checked.
How to fix the trouble? The root cause here may be the stretching of the cables, the presence of dirt on the gaskets. The solution is to remove them from the jackets and flush the connections from rust using a special WD40 tool. In the event of a break or critical damage to the sections of the cables, you will have to replace them with new ones.
Should I lubricate the ropes with oil? Experts do not recommend resorting to such actions. It may be easier to change gears at first. However, over time, the grease-coated cables will adhere to dirt, making them much more difficult to move.
It is necessary to lay the cables in shirts so that their bending angle remains minimal. This will avoid excessive friction.
After servicing or replacing the cables, it remains to re-adjust the gear selectors. Finally, you will need to ride the bike, checking if the pedals are cranking as before.
Often the center of the problem is an old or worn chain.
If it has not been cleaned for a long time, then you need to clean it with a rag, kerosene and an old toothbrush to clean in inaccessible places.
After that, it is recommended to let the chain dry, and then lubricate with a special oil (silicone-based). You can prevent this situation if you hear a creak in advance or the pedals will start to spin harder. In this case, the chain is wiped prophylactically.
There is another situation when the chain is too stretched.
This is determined by external examination:
- If it hangs, then the reason is this. In this situation, it can be shortened.
- To do this, you need to find a specific link on which there will be a latch.
- It fixes the ring connection. It needs to be removed.
- To shorten the chain, you need to remove several links with a hammer by knocking out bushings from them.
- After that, put the retainer back and put on the chain.
- If after all the above operations nothing has changed, you need to change the chain to a new one.
