Upgrading an old bicycle

[kacper6768]

Would it be possible to make a battery for an old bicycle myself to convert it from a regular bicycle to an electronic bicycle. There is acid in batteries. If I pour, for example, acid from cucumbers or other kitchen acid into an ordinary bucket of paint and pull out 2 cables, one plus and the other minus, and plug such a bucket with a lid and connect these cables to the socket, would such a bucket make a battery? How can I make my own battery acid in the cheapest home way so that I don't have to spend a lot of money on original bicycle batteries? I don't need any complicated electronics or gears or counters or controllers in the bicycle just to have any pedaling support at the cheapest cost.

uhhhhhhhhhhhh idk about the battery acid at home but tom stanton (https://www.youtube.com/@TomStantonEngineering) has a bunch of videos on bike propulsion for cheap

Surely most of that isn't serious

You can easily covert a bicycle to electric, it replaced the rear wheel and you install a provided battery pack.

It won't be as good as most off the shelf electric bikes.

You can simply buy acid. It's not expensive. It is, however, not pleasant to deal with. It's also not all you'd need to make a battery, and the type of battery that uses that acid generally isn't the type of battery used in most electric bikes.

 

I really don't think you're going to be successful with this endeavour without doing a significant amount of additional research.

Can you make a cheap battery like this?

Yes

 

Will it have enough power to power a bicycle?

No

I use a Shneider bicycle with Shimano 3CC gears and I have this round wire sticking out of the bicycle.

Should this round wire be inside or outside the bicycle and should it be in contact all the way or should it have a break?
When I ride a bicycle, this round wire enters the bicycle and immediately comes out, but most often it enters in the middle and moves so that it hides in the bicycle and comes out. When I pedal the bicycle, I can hear in the rear wheel mechanism that something is rubbing strongly, that I can feel vibrations and something is braking in the bicycle, but I don't know what.

It happens to me that I take on the repair of devices that I do not know. When I was disassembling the entire derailleur mechanism in this bicycle for the first time, to grease it when they squeaked a lot while riding, all the parts flew out right away that I didn't know how to assemble them and in my spare time for a few hours a day for a week I would assemble it. On this bicycle is in such 2 parts on the left and right parts of the derailleur

the plates that hold the balls were crushed, I put the balls manually in the place where the circle in the balls should be and I threw the crushed plate away, but when I put the balls in, there was a free space, I put balls from other broken bicycle bearings in this free place, but if you spin the derailleurs again, then these balls fall out and you have to be careful not to lose them, is it possible to buy such a part but I noticed that these wheels are of different sizes the same and in the derailleur a small type of balls and in the pedals a large type of balls what about that I have spare wheels with balls if the size does not fit.

Is it possible to buy just this small balls?

is it better to buy such balls mounted in a circle?

I noticed that the bike rusts over time and the screws in it are so rusted that it is impossible to unscrew them, which I did not unscrew them. Only those screws that I unscrew often can be unscrewed. Is it a good idea to turn the screws in the bicycle with a screwdriver once in a while, even if the bicycle worked well, just so that the screws don't get stuck and I can unscrew them later if necessary?

What is bicycle in english? Cycle or bicycle or bike?
The word bike accociates me more of a motorbike.
What is motor in English? Is it a motor or motorbike or a bike or a motorbike?

There is a rusty chain in the bike that does not want to bend in some places. If the chain was soaked in ordinary cooking oil, would it bend? I don't have motor oils or money to buy them.

Cooking oil won't penetrate the rust and probably won't last very long as a lubricant. It will also go rancid pretty quickly.

 

You need a mineral or petroleum oil. Even used engine oil might help, but it will probably sling everywhere once you start pedaling.

 

You can also somewhat loosen up stiff links by bending the chain back and forth laterally (not the direction it normally bends). 

 

Berm Peak is a YouTube channel mostly aimed at tail and downhill mountain biking, but they have a ton of useful repair videos like this:

 

You don't need the expensive brand-name tools he uses, cheap generic ones are generally fine.

 

As for that bearing, what did you take apart exactly? I've seen those in the crank housing, and pedaling feels 'crunchy' when they go bad. Don't try to just replace the ball bearings, because that won't last. You need an entire bearing, which shouldn't be much more expensive anyway. You'll want to completely pack the bearing with fresh grease, then add more grease to the crank housing before reassembly. 

 

And no, a science experiment battery won't have enough power for an ebike. You don't want to use lead-acid batteries in the first place, especially not a homemade one that isn't sealed.

 

What region are you in?

Opatów in Poland.

 

The picture of the bike doesn't show what is being talked about.

Replacing bearings and knowing how they fit is something I've only been doing for 60 years or more. And yes, I've seen some who don't know how and I'd suggest you take it to someone who knows about those things.

 

The bike is very rusty so I'd expect it needs a total dismantle and rebuild.

 

If you have to ask such basic questions about acid and batteries, DON'T try to make one or even think about using one.

 

Why do you need or want an electric bicycle anyway? Your area looks to be flat.

I might get an electric bike for my 100th birthday but until then I'll carry on riding my normal bicycle every few days. Twenty years ago I'd be doing 20 km every day to work and back. Not long before that, a quick 70 or 90 km ride over the hills in the weekend for some exercise. No electric biking.

The metal on the rear wheel derailleur broke on Schneider Shimano 3CC cycle. does it mean that if this metal breaks more, the derailleurs will stop working completely and can this part be replaced or welded? I've been using this cycle for 14 years and it was bought used. Is it the fault of the bad use of this bike that it has a crack or would it break there anyway?

 

The derailleur cable broke

 

 

this is the second part of this cable

 

 

I got a frame from another broken bike

 

 

is whether to take these cables from the derailleurs from this frame or glue that cable somehow. I only have soldering irons but the soldering iron does not want to solder this cable. I've been using this bike for 14 years and it was bought used.
