FX+ 7S?

Having said that, you may have gotten water in/on the bike’s power controller. Hope when it all dries out that it works for you. You may need to do some part swapping to locate the failure. Honestly, I doubt it was the display, but of course many things are possible.

At least on Specialized e-bikes, the top-tube display is also the central controller for the bike. Get it wet internally and it will act pretty much like the OP's did -- you're not going anywhere without it.

The TQ is the same way. The display is the controller. The system itself has sealed connections, don't know about the display itself. If there's a seal between the display and the frame, that's on the frame manufacturer.

Interesting. In the immortal words of Johnny Carson… I did not know that!

Dropped the bike off at the shop today. Even they were insinuating that it's my fault for leaving it outside. Not surprising that an employee working at a Trek dealer geared more towards recreation would say that. Still disappointing and frustrating though.

My Vado SL has been rained on countless times, while I'm on and off the bike, and there's never been an issue. The display also has a better design that won't let water into it at all.

When I get it back, I'm just going to have to add some type of protection to it myself, which I shouldn't have to do. This is a pretty big negative on what's otherwise a great bike. It's also apparently a common issue with this display from what I've seen online. Had I known of this issue ahead of time, I wouldn't have bought the bike.

I wouldn't expect anything from Trek dealer email support for the end user. They are not there for you, they are there for your dealer.

The TQ system itself has a pretty good water resistance rating. The motor and battery are IP67, and the display, remote, and connectors are IP66. It's up to Trek to seal the display to the top tube, but that doesn't explain why your display had moisture inside. Get the bike to your dealer. The display should be warrantied.

That's unacceptable, @BakedPringles! Not only have I been on some bike tours where we had to ride in rain most of the day, but, even when riding casually with my local group, we don't start off intending to be rained on but it certainly has been known to happen. I can't imagine riding a bike and being afraid that it might konk out if the skies open.

It should be noted that while there are some UL standards about batteries, I don’t think there’s any standard about water prevention for e-bikes in general. I even have a UL listed battery which is fatally-flawed with open ports (but easily sealed) so don’t get cocky and think you’re immune to the elements. I say this for all bikes, and some of you folks who think you’re immune will find out someday that you’re not. Water/salt/sand are pretty pernicious.

Go over your bike carefully. Buy some sealant or at least non-conductive tape and figure out how to keep the water off/out. Also, avoid direct water spray when cleaning your bike.
