Compared to traditional bicycles, folding bicycles can be more convenient to use.
The small size of the foldable Bike allows you to take it on buses, subways and other means of transport or in lifts, making it the best choice for convenient urban commuting. You can easily put it in the trunk of your car and take it to your destination to ride your bike, and it's affordable, compared to mountain bike road bikes which are more cost-effective in price. The Foldable Bike Parts usually cheaper than the mountain bike parts. Such as the Bicycle Hub, the frame, etc.
However, the drawbacks are also obvious; the folding frame are not as strong as the one-piece frame of a mountain bike, and climbing hills is more strenuous than with a mountain bike, btw, the front Folding Bike Hub is too small for force. It is slower and less comfortable than a mountain bike on long rides.
If you ride in the city, or go for a short ride once in a while, it is fine to buy a folding bike. If you climb a lot, like to go off-road, or ride long distances, the mountain bike or the road bike is more recommended.

For the cause of the cracking of the gear cover, the following series of effective countermeasures can be taken.
The four-point positioning is originally designed by the locomotive. Under the premise of ensuring the clearance between the inner side of the gear cover and the gear end face (3 1-2 mm for the pinion end and 13 3-2 mm for the large gear end), the purchase or processing specifications are complete. The gasket is carefully and repeatedly adjusted to be as flush as possible to minimize internal stress.
The original gear cover has a wall thickness of 3mm Boshan Qingshui Pump, and all of the gear covers with a wall thickness of 5mm are now purchased, which greatly improves the strength and rigidity of the cover. Reduce fatigue damage and increase service life.
The gear cover of the cracked part is all removed and repaired, and the old welding wave is partially removed and re-welded to eliminate the problem that the welding part of the original welding is not welded and the welding angle is not accurate, so as to ensure the welding quality.
Once you find that you are not responsible for getting off the train and repairing the old solder wave, you will be given financial penalties. At the flight attendant learning meeting, the role of tightening bolts and the importance of installation were reiterated. The maintenance driver inspected the loosening and loosening of the bolts on a daily basis. Once the loose and lost were found, the company immediately imposed economic penalties.
After adopting the above specific measures, all indicators can show a downward trend.
