How Many Moving Parts on a 50+ Bicycle?

Or any bicycle, for that matter?

I am sure it must be less than on a car. Then, why is my bicycle(s) under repair/maintenance/update, etc., many times as much as my car - which requires a lube job/oil change about every 3,000 miles (knock on wood)?

That's an interesting question. I even used to know the answer but I'm not good at remembering numbers. I do remember that more than half of the moving parts are in the chain.

The chain has to operate in a rather adverse environment. It's out in the open and the front wheel throws water and crud onto it every time you steer a tiny amount to the left. Not surprisingly, the chain is the component that demands the most maintenance attention. I do almost nothing on any of the other parts of my bikes.

Now that's for a 50+ bike. My son rides a 35+ bike. His bike has about the same number of moving parts but his move a lot farther and faster than mine.

I read the OP title and thought it said, "how many moving parts on a 50+ human".

Do we count each spoke, nipple, and chain link as an individual part or as a unit?

I guess it depends on how many links on the chain, spokes in the wheel, balls in the bearings, etc.

Your real question is why is your bike in the shop so much compared to your car. That question I will not touch.

All of them. When you're riding all the parts are moving on down the road.

Have you been cleaned, lubed and adjusted recently?

I could figure it out, but then I would forget what it was.

DnveFox, Motorcycles aren't a whole lot better when it comes to maintenance intensity than a bicycle. Part of the importance has to do with only having two wheels. Poor bicycle maintenance can not only strand us, but also cause pain.

Thinking back over the past year I've only lubed the chains and inflated tires on the bicycles I haven't tinkered with for other reasons. One of my cars had alot more maintenance! I shouldn't be too sad tho', it could've happened on a 2200 jaunt to the east.

Me, too. I used to be a maintenance fanatic, lubing everything and checking everything before any ride of significance, tearing down the headset and BB at least once a year, repacking pedal bearings in my idle moments.
Now I pretty much check the tires and go, but I do lube the chain every 100 miles or so. I know for sure the BB on one of my bikes has at least 12,000 miles on it, and I just replaced the original headset on a 1985 Bridgestone I use as a beater.

When I was a 4-season all-weather commuter in Atlanta a long time ago, I spent a lot of time servicing chains, pedals, bottom brackets, hubs, etc. As with Velo Dog, now my tires get air added, the chain gets an occasional wipe and light lube, and that's it until something really needs attention, which isn't very often.

Because your bike is something of a precision instrument and your car is not. The average car probably has a dozens of things out of adjustment or in need of replacement. If you took your car to a NASA type repair shop and asked that everything be bought up to "new" specs. I imagine the bill would be $10K. With respect to my 740i, $40K.

Hmm!!

I would venture to state that clearances between pistons and cylinder walls (and other clearances), for example, are manufactured to a degree of precision exceeding that of any bicycle part.

I think a lot of people go overboard on the bike maintenance. Also, while you do some things to your bike more frequently, often the jobs just take a few minutes. Compare brake work on a bike with brake work on a car. I think if you included putting gas in your car as maintenance, it would change your perceptions as well.

And would you include as bike "maintenance" the cost of putting fuel (food) in one's mouth to feed the bike "motor?"

No one has taken a guess yet. Since every part on a bike moves, I'm going to guess at how many individual parts if you took everything apart.

Here are some guesses:

I took my chain apart to count, but lost some of the pieces.



I'd say about 270 parts in the chain.

Front wheel, 32 spokes, 32 nipples, 1 rim, 1 hum, 1 tube, 1 tire, two valve nuts, two valve "bolts," a valve cover, 20 bearings, 2 cones, 2 spacers, 1 skewer central part, 2 springs, OK, I'm bored.
