kids bicycle replacement parts image
Someone el
I am looking to buy a bicycle and was wondering if this is a good buy, and if it is worth the possible trouble. The bike is a Nikishi 12 speed "sport" model. It is about 20 years old but in very good condition (looks more like 5 years old). Problem is, it came from overseas and has metric parts. Also he is looking for $75. It has no extras except for a bike rack and a bottle holder. It does not look like it needs any work.
First question. Is this a good value for the bike? I have no idea if this model or brand is any good.
Second question. Will I have a hard time finding replacement parts for a metric bike? Also will I have a hard time finding "add-ons" for it?
I plan on using it to ride with my kids (4 and 6) and commuting to work (2.5 miles).
Thanks!
Sorry the model is Nishiki, not Nikishi... probably a minor detail.
Also, I am on a VERY limited budget. I cannot really afford a brand new bike.
Answer
$75 seems a bit high for a 20 year old bike, even if it is in good shape. The metric parts are not a problem, most new bikes are also metric. The 6-speed cassette (rear gears) might be tough to find if they ever need replacing; most, if not all, new bikes have at least an 8 speed cassette and they might not be compatible with your chain.
Add-ons, such as a rack, saddlebags, lights, etc. are pretty universal so you shouldn't have trouble finding those.

Answer
There are no single answers to your questions.
Do you understand that the rim is the part of the wheel that holds the tire, the hub is the part that allows the wheel assembly to turn? Combination of rim, hub, and spokes make the wheel.
1) There is no ideal weight. This depends on how you will use the bicycle and what the material is. Since the rim is the outside of the wheel it will be most efficient when it is very light. When a rim is very light it will be either very weak or very expensive.
2) There should be no worry about the weight of a hub. It is too close to the center of the wheel revolution to make a significant difference in inertial forces. I prefer more strength instead of lighter weight, like Phil Wood or Hi-E hubs.
3) I think you have already asked this question. Most kids bike rims are 16", 20", and 24". Most adult bike rims are 26", 27", 650C (571mm), and 700C (622mm) in diameter.
4) Aluminum is the best for durability and value when making rims. Magnesium looks promising in the near future. Titanium and carbon fiber are too flexible or too breakable and way too expensive for rims.
5) You cannot separate hubs from bearings. You must have bearings inside hubs. My preference is for stainless steel ball bearings with hardened steel races and cones. Many people prefer sealed bearings but I like to service my own hubs without replacement.
6) Most modern hubs use sealed roller bearings, usually made from carbon steel but these are not serviceable.
7) You asked this before. Please note your last question.
8) There are many brands of bicycles from all over the world. You will have to do this research by yourself.
I do not think you are using this for college. It seems you are making market analysis for your product. If this is true you are cheating yourself by asking others for this information.
