The WHEELTOP EDS GeX is a wireless electronic 1x gravel groupset that offers exceptional versatility (3-14 speed compatibility) and strong hydraulic braking at a fraction of the cost of SRAM/Shimano electronic groups. However, it suffers from a finicky app, inconsistent setup, non-removable batteries, and long-term reliability concerns, making it a value-oriented choice for DIY enthusiasts willing to tolerate quirks.

Reviews & Ratings
34:27The reviewer includes the WHEELTOP EDS GeX electronic groupset in an AliExpress gravel bike build, noting that he paid for it himself and that it is an electronic shifting system. He shows the brake calipers, which arrive pre-connected to the brake hoses with pads and protective covers installed, plus a small parts box with bolts, olives and mounting hardware. He notes there is no included instruction manual for which bolts go where. He installs the flat-mount calipers on 160mm rotors, routes and shortens the hydraulic lines, and bleeds the brakes with EZMTB Shimano mineral oil following the Wheeltop instructions. He mentions the levers already had power and that the rear derailleur shifted while still in the packaging, indicating it works. He had trouble accessing the lever clamp bolt and had to redo a brake line after assembly mistakes. Detailed riding or shifting performance is deferred to later parts of the series.
23:24The reviewer does not explicitly discuss a 'Groupset' as a single component in the transcript. Instead, they describe assembling a mixed component setup, including a crankset (with 175mm crank arms and Torx screws), an electronic Wheeltop EDS G rear derailleur, and a KMC waxed chain. They mention using ChatGPT to help determine component compatibility with the BXT frame and express hope that the mixed components will work together.
34:27The reviewer mentions the groupset only briefly, noting that the build will use an electronic Wheel GEX groupset, which he paid for himself. He does not evaluate its performance or provide detailed commentary in this excerpt.

While the shifting and brakes worked well when functioning, they encountered random bugs, a complete shifting failure during a race, and a hardware failure in the right shifter.

I just wanted to add my 2 cents to this convo. I am a dealer for wheeltop and have set up a few bikes with the road gruppo. I am no where biased to wheeltop as I am a shimano fanboy. What I can say about the gruppo is. 1 it was a pain in the ass first time around to set up the fd as someone else has said here the trim screws do nothing. The Rd is clunky. The app sucks. Now haveing said all that once I got over the first time pains and I went on to insatll it another time on another bike I can say. Fd was a breeze to set up the app still sucks but what it does allow is great. It allows you to use 3rd party cassettes and trim them perfect for flawless shifting. I wish the group was much lighter but app its in the works. Being from canada I had a issue with 1 of the shifters. Customer service from the wholesaler was fantastic. I will say this if the group was the same weight as a duracace and im fine if the gruppo was more money it would be my gruppo of choice.
real world exp. here... mounted on my gravel Niner RDO 46/30 ... 11-34/11sp (edubied monoblock) absolute no glitches whatsoever...it just works, now since May! Yes, setup isnt for the 'faint-hearted' but hey...its still fun...from what i saw, they updated some of the setup instructions/videos. App design still quite the same...which is a bit...weird... and whats really amazing..you can finetune each cog if needed...e.g. range of 11sp cass...gives you around 0-1800 index units in the App so for every step you have roughly 180 IU to play with...to give you an example how much micro fine tune is possible. it also has autotune for the FD... and FD is my only complain...being not as powerful under load for shifting.
