Datacenters are how the internet works

As the other poster noted, they are quoting you for a lot of maybes.

But also, a big part of the price is simply supply and demand. There is a shortage of experienced, skilled laborers, and it isn’t going away anytime soon. If you are dealing with an independent contractor, for example, your price needs to not only compete against other potential projects in terms of time/effort, but also must compete against the alternative of “what if I just fucked off and hung out with my friends instead?” The beauty of having experience in skilled labor (right now at least) is that your skills are in short supply, but are largely interchangeable with anyone else with the same skills. So if you were to get fired - or just quit because you don’t feel like working - there is no hurry to find another job. You know you can find another job almost instantly. Which is why I know several contractors who just work summers, and then fuck off and go rock climbing the rest of the year.

I would be pretty wary of using it with that amount of voltage. If the electricity routes through you, it would probably give you more than a good buzz.

Based on the fact that it made your fingers tingle before you replaced the motor, I doubt the new motor or your installation of it is the cause of this issue. You probably have some kind of short inside the machine itself. Best bet is to crack open the machine (when unplugged, obvs). This could be the most dangerous part - make sure you can identify capacitors on the circuit board and find a youtube video about safely discharging them, as capacitors can store dangerous amounts of electrical charge even when the circuit is unplugged, and discharging them accidentally can fuck you up. Then look for obvious loose connections. If you don’t see that, you will have to start searching for the short. Set your DMM to measure resistance. Search the motor component with one lead and the rest of the machine’s circuit with the other. As long as resistance is a real number, you have a closed circuit and the short is on the circuit the leads are on. When resistance jumps to infinity, you are no longer in a connected circuit, and the short is somewhere else. Often, shorts will read as significant amounts of resistance, as the marginal connection between two components is not enough to allow free-flowing current. Note that this creates a new danger - even if you don’t electrocute yourself with the machine during use, it is possible it will catch on fire as electricity running through a marginal short heats up the components. If you are lucky, you can identify the short by noting the leads have non-zero resistance in one spot, but 0 reistance upstream and downstream of that spot. Then you might look real close and see a loose wire or a burn mark. But maybe this is just an expected bit of resistance that was designed into the circuit. It’s a bit of an art, takes some patience, and if the solution isn’t immediately obvious, there is about a 70% chance you are wasting your time.

Ideally, as the other user said, you would also install a ground during your troubleshooting so you don’t electrocute yourself in the future if it happens again.

Unlikely, simply because this would require some pretty major scientific breakthroughs, and most of these breakthroughs happen from scientists collaborating between institutions. Sure, the actual implementation might be developed privately - but the underlying science would be public domain, and it wouldn’t be long until there were competitors on the market, shouting from the rooftops and slashing prices.

Yeah, I would rec refining your vision - you aren’t building a solar charger for your bike, but building a solar system which can charge anything.

I won’t say I’m an expert in these systems, but my recollection from building out my van about a decade ago was that you want solar panels, a charge controller, a battery bank (maybe), something for your load to plug into, and an inverter or adapter for your bike.

Electricity comes from the solar panels, but it varies in volatage or amperage (i forget) as the sun varies in intensity. A charge controller smooths this out, and will output the appropriate constant voltage at an amperage determined by your load. The battery is there to accumulate power when you arent running anything on the system - after all, the sun shines during the day, which is probably also when you want to ride your bike. Also, I remember something about it is dangerous to not have a battery on some charge controllers, since the electricity needs somewhere to go even if you have no load - but maybe thats bullshit. So the CC and BAT work together to provide power for you to use for whatever load you want, but it is DC power. From here, you have to choose between the more expensive and dumb path, or the more adventurous and dumb path.

The expensive and dumb path is to get an inverter to convert your power to AC. This will let you plug your bike in like a normal wall outlet. Done. But inverters cost an annoying amount of money, and you are also wasting a good chunk of your generated electricity converting from DC to AC, which would be fine if you actually needed AC - but then you are losing even more power converting back from AC to DC. Ridikidonk! But this has the added benefit that you can also just plug, like, your laptop charger in if you just want a normal outlet to use.

The adventurous and dumb option is to modify your charger and/or make your own charger to convert from (probably) 12v DC to whatever voltage your bike needs. Iirc, amperage listed on the charger doesn’t denote how much current you need to provide - your power source will provide as much amperage as it can until it runs out of power - but denotes the maximum amperage the device will take. Presumably, this should be as simple as getting some little electronic componenet to step up your voltage to an appropriate level, and then getting that electricity into your bike charging port… but if the charging port on your bike is proprietary, like the other user said, the easiest solition is chopping off the end of the cable and using that. A slightly more difficult but still easy enough (maybe?) option would be to splice in an alrernate charging port on the bike itself that you could use when at home, keeping OG cable as-is for charging on the go. Or maybe the cable connector isnt proprietary, just obscure, and you can find a supplier on alibaba.

So you have solar, charge controller, battery, and inverter or load. Between all these are wires. The wires need to be the correct guage to handle the anticipated amperage, or they will catch on fire. Then you need to put fuses in all the wires in case they end up with too much amperage anyway, so they don’t catch on fire. And then just in case they catch on fire just because, or someone starts getting electricuted by your poorly planned system, you’ll want some clearly labelled and accessible cutoff switches between solar/CC, CC/BAT, and CC/load.

As you can see, this is, in fact a whole thing. And I do wonder if everything I just wrote was a mistake, and you may be better off just building a dedicated bike-charging system using more basic electrical components… but hopefully you have a better idea of the problem space. I expect your challenges will be:

1. Taming the wiley solar output.
2. Ensuring sufficient power for the bike’s needs even in non-ideal solar conditions.
3. That friggin charger connector.

If economics are supposed to push people to change, apparently the prices are still not high enough

Yes. In parts of the world where the cost of gas is actually significant compared to the typical wage, we see a lot more use of small engine vehicles like motorcycles and scooters - and these places are electrifying far more quickly as well, since the people have a real economic incentive to.

Much as lemmy hates to admit it, economics is a thing, and increased oil prices will drive consumers to make less oil-dependent choices for their transportation needs. Ideally, this would also come with effective pressure on local, state/provicial, and national governments to reform land se policies and invest in low-carbon infrastructure as well. But even if they don’t, people and businesses will eventually find the cheapest way to get around somehow.

Oh, those french children. Digging up corpses again. Rascals!
