My experience after one year with Wheeltop EDS GeX – I would NOT recommend it
I've been riding a Wheeltop EDS GeX 1x13 for about a year now, around 5,000 km total. Bikepacking, races, everyday riding, after-work rides, etc.
To start with the positive: once the system was set up, shifting generally worked well. The brakes are also fine and I actually like the ergonomics. One thing to note though: the levers sit quite far away from the bar, so I think you need fairly large hands to use them comfortably.
The app is another story. Some of the translations/settings are pretty poor and can be confusing.
Unfortunately, I've had quite a few random bugs and errors over the year. Nothing that happened constantly, but enough to make me question the reliability. I even had the shifting completely stop working during a gravel race once. I had to stop and set up/pair the system again before I could continue.
Now I've had a hardware failure as well.
At the beginning of August 2026, the right shifter stopped recognizing its two buttons separately. Whatever I assign in the app, both buttons always perform the function assigned to the small button.
For example:
Large = "+" / Small = "−" → both shift "+"
Change the assignment:
Large = "−" / Small = "+" → both shift "−"
The shifter is still detected normally, the gear position is displayed correctly, and the rear derailleur itself works perfectly when shifting through the app.
I've tried new batteries, firmware updates, re-pairing, resetting everything and resetting the button assignments several times. The problem is completely reproducible.
I sent Wheeltop a detailed description and videos showing the problem.
Their response was basically just: warranty expired, buy a new groupset.
The warranty had expired by only a few days. I wasn't asking them to replace the whole groupset. I was hoping they would at least look at the problem or offer a replacement right shifter.
But there was no troubleshooting, no technical analysis, no real assistance and no offer for a replacement part.
This is probably what annoys me most about the whole thing. After around 5,000 km I can say that the actual product isn't bad. When it works, it works well. But I need electronic shifting to be reliable, especially when using it for bikepacking and racing.
The combination of random errors, an actual failure during a race, questionable spare parts availability and now basically zero support when a component fails has completely changed my opinion of the system.
I originally bought Wheeltop because I liked the concept and wanted to give a smaller manufacturer a chance.
I wouldn't buy Wheeltop again.
Personally, I'd rather spend the extra money on Shimano or SRAM and have proper spare parts availability and customer support. It's a shame, because I actually enjoyed riding the Wheeltop for the first year.
