I own both of these bikes (2020 Levo and 2022 Wild FS) so here is my opinion: I started doing research on E-MTBs in 2019. After a few months of research it seemed the two best bikes would be the Levo and Wild FS based on reviews, etc. I bought the Levo April 2020 and Orbea March 2021. Both bikes came equipped with 29" wheels front and back.
.
I have since put 2000+ miles on the Wild and 1000 miles on the Levo. The Orbea has had 0 problems. The Levo motor overheats after about 9 miles and throws an error every ride (started after 500 miles) and requires the bike to be turned off and turned back on and the error goes away - this happens even on flat rides. The main use for the Levo now is take people out who are interested in getting into E-MTB for a demo ride.
.
For some reason, I prefer a bike with a vertically mounted shock. It seems to give a much more linear response and make the bike more rigid when climbing. The 45 degree angle of the Levo shock seems more "squishy" and non-linear in the response and has more sag regardless of shock pressure and settings. I have experienced this on multiple bikes both E-MTB and MTB but it could just be in my head.
.
Both bikes were upgraded to Shimano XT brakes (N04C pads) and XT Ice Tech Rotors, Ergon SM-E saddle, One Up flat pedals, and One Up Carbon 35mm bar and headset. The Fox 34 fork on the Levo was replaced with a Rock Shox 38 Zeb ultimate and the Orbea came with a Fox 38 grip fit fork. So, both bikes are similar or equal in components at this point. Both bike frames are larges and have very similar dimensions.
.
One advantage of the Orbea is that it has the ability to add an external 500W/hr battery which gives a total of 1100W/hr compared to the 700W/hr battery of the specialized so range anxiety greatly decreases, but it adds 10 pounds to the bike. The standard Orbea Wild FS comes with an internal 630W/hr battery. I recently converted the Levo to a mullet and that made it a bit snappier on trails and downhill. The next E-MTB I own will definitely be a mullet.
.
Bosch vs Specialized Brose Motor: The Bosch motor on the Orbea is quiet and smooth, plus it adds the EMTB mode which is something of an adaptive version of trail and turbo modes combined. It has performed flawlessly for 2000+ miles and i have had zero problems with the motor, battery, electronics, and the bike. The Levo motor has gotten louder over time and after around 500 miles started posting an error after about 8-9 miles of riding or 60-90 minutes. This happens both on pure flat and out in the hills but does happen every ride. Since it can be fixed with a reboot, it isn't enough of a problem to take it in to the dealer at this point. However, I am worried that it will eventually fail and be out of even the extended warranty Specialized handed out due to the high failure rates (4yr vs standard 2yr).
.
Summary: I prefer the Orbea due to handling, extended battery option, and the Bosch motor has worked flawlessly.
.
One more thing: I wouldn't buy a used E-MTB. The warranty for most brands only applies to the original owner. In most cases, this only applies to the frame because that is the only thing actually under warranty by the bike company. All other components, including the motor and battery, have a different warranty based on their manufacturer. Specialized is the exception, since they have designed there own motor and battery based off a Brose design but they warranty it so it would be good to establish a relationship with a solid dealership if you buy a Levo. GP Motorsports in Campbell, CA is where I bought my Levo and they are great if you are in the SF Bay area.
.
Last, both of these bike designs are based on 2018 designs that have been slightly updated and there are now many more options that are more current with the industry. Two people I let ride my Levo both bough Canyon Spectral:ON CF8s and really love the bike. It is a mullet, looks almost identical to the Levo, but also comes with a 900W/hr battery for under $5000 and if I didn't have an E-MTB at the moment I would likely get this bike even though it doesn't have a vertical mounted shock. Giant also has some great E-MTBs using the Yamaha motor with great reviews.
