Hello,
To start off: I’m not a pro biker. I purchased an electric bike HeyBike Cityrun in May 2024 (3 months ago). I got it from an authorized dealer and got the assembly + tune-up package, so that it’s ready to go.
Love the bike. Over time, some screws got loose under the saddle and on the kickstand – I’ve contacted the dealer and they told me these needed to be tightened periodically due to the vibrations – fair enough.
Today, I felt the front wheel was kinda off. I sent a video to the dealer, whom told me that the alignment washer and bolt were BOTH missing from my front wheel axle. He told me where to get replacement parts and not to ride the bike as it’s dangerous.
Is it reasonable to expect these parts to just pop off mid ride after 3 months? I do my due diligence, but I wasn’t expecting that such important parts could just loosen like that, unnoticeably.
I’m just wondering if it’s reasonable loosening over 3 months, or if I can assume it was not tightened enough originally during the assembly.
Any info is welcomed – video for info (you can see how clueless I was that something was even missing ahaha)

No, it’s not reasonable, you should had been checking that your bike is in a decent condition before riding it.
I’ve never had one of these fall off in my life. Based on what I can see in the video nothing is damaged, just missing. That tells me that is really did just fall off- and the only way that would happen is if it was never tight enough to begin with.
Whoever the last person to remove that wheel was didn’t tighten it up enough. Assuming nothing is damaged, just make sure to check it periodically. I do on my bikes- as a mountain biker, something coming loose could cause seriously injury, so it’s just become a habit to check frequently.
It’s because after 3-6 weeks you should take it back for a bolt check and tune. This is why it’s a thing so shops can make sure nothing’s coming loose. Ebikes especially with the extra weight needs this more often and there usually ridden but people with less confidence to do work themselves. So maybe go over every bolt on the bike and see what it needs.
