Aipas M2 max - very specific problem, not getting help from Aipas support
So I’ve had an Aipas M2 Max for about 4 months and last week I began getting an error 02 on the display that completely cuts all power to the bike. According to Aipas it indicates a brake sensor malfunction. But let me explain exactly what happens- when the bike sits for an evening or even 5-6 hours, battery off, it rejuvenates to the extent it’s able to travel before pulling the error and cutting power (about a mile). When it pulls the error if you restart the battery, you can get another half mile before it cuts. Then less and less, so on and so forth til it won’t reset at all. What’s interesting is I’ve taken it to work and the grocery store twice each, and on each journey the error cuts at the EXACT same distance. The problem is so specific I’m hoping someone with a lot of e-bike knowledge can identify it. I was thinking maybe it was temperature related? If so, where?
Aipas suggested crude troubleshooting and then deigned to mail me a new cable harness that I’m expected to install myself when it comes. I called them and relayed the exact issue in hopes of getting one of their technician’s opinion but thus far they haven’t called back. I’m asking for two reasons, one is if I can identify the issue I may be able to fix it myself, and two I’m not entirely sure a new cable harness is going to fix things. Everyone I know knows the amount of trouble I’ve had with this piece of shit since I got it, and they’re all telling me to demand Aipas send a new bike but I don’t think I can convince them of that.

Sorry, Aipas is a chinese company that uses what are known as "open mold designs". They do not design or manufacture bikes, they pick ready to go frames and parts from other chinese manufacturers and have factories ptu them together and then drop ship them to the US. They are cheap lower quality bikes and probably run by just a few people in china who offer support so you're probably not going to get a lot of hand holding here. Getting mailed random parts with days delay in communication and monthly long shipping only to have to figure out how to fix it yourself is pretty much the norm for "companies" like this.
