Countless companies and industries enjoy making up scary stories when it comes to justifying their opposition to making it easier to repair your own tech. Apple claims that empowering consumers and bolstering independent repair shops will turn states into “hacker meccas.” The car industry insists that making it easier and cheaper to repair modern cars will be a boon to sexual predators.
Almost got scammed by Rad Bikes this way. Battery mysteriously failed 10 months into their 1 year warranty. Rad Bikes accused me of sabotaging the battery and refused to honor their warranty, but “generously” offered me free shipping on a $300+ replacement battery. Turns out the off-the-rack fuse they use blew; identical down to the manufacturer to the ones used in cars. Replacement fuse was <20 cents and fixed the problem instantly.
Do you recall the specific fuse? There was someone asking about ebike battery fuses on !micromobility@lemmy.world a while back. Wasn’t really sure what to tell them, but automotive fuses make sense.
On my RadCity 5 Plus, it was a 10 amp red mini-blade fuse. I had a “variety pack” in my car that I’d gotten at a local auto part store, but looked it up any way, just in case. This may be different on other models/batteries. Ironically, it did require a warranty voiding opening on the battery casing. :-)
Fwiw those “warranty void if opened” stickers are not legal
What tripped the fuse, though?
Rad City support could not or would not explain how my battery might have stopped working, but would only say it was “not covered by warranty”. They could also not explain what sort of causes of battery failure were covered by their warranty. It was pretty clear they just didn’t want to cover the expense of honoring their warranty (the battery is probably one of the single most expensive parts on their bikes).
This may be a combo business problem where they don’t have enough technically qualified people to troubleshoot with you. It’s cheaper to pay minimum wage for someone to just do replacement customer service than it is to pay someone with more valuable knowledge and sit on the phone for an hour with you. I have a bad habit of just tearing things open now, assuming the company can’t help me. But it usually works out
