Ok so I still have my Gen2 carbon expert Levo 700w 2019 and I also have a 2021 XT air build Bullet.
the bullet is a better bike but the Levo is a better ebike. I know that sounds odd but this is how Icome to the conclusion.
I have hada Levo gen 1 and gen 2 for 4 and a half years.My gen1 had a motor and battery after it got super wet but other than that it was an excellent bike. I have had 3 motors anew wiring harness and the TCU replaced on my Gen2 Levo. Specialized warranty is second to none and Birkshire cycles always got me up and running whilst I waited. The 700w battery and the Brose motor when it works is significantly better than the shimano EP8 and 630w battery. It’s no contest really the powers and the way it delivers it is much better on the Levo.
Range is a big issue on the bullet. I dropped from 92kg to 80kg this year just to try and improve the range on the EP8 and apart from being in the best shape of my life for 20 years the range gain was negligible, I genuinely get 30% less range from the bullet. I have fixed that now by picking up a second 630w battery but that took me 5 months to track one down, they are not in stock anywhere.
This is my experience and people will claim they get more and it’s about the tune but I have both bikes with over 2500 miles on the Levo and 600 on the bullet so I think I have a good benchmark.
as for the ride, it’s difficult to compare, my times and ridding came on leaps and bounds on the bullet it’s a lot more capable than the Levo. However I should have got a Gen3 Levo, I think that would have suited me more.
Now I have the extra battery I’m sorted to keep the bullet for the 2022 season I am sure in the next 12 months Specialized will bring out a 800w plus drive train and revise the Levo for 2023 to get back ahead of the market, I will put a deposit down as soon as that drops.
I paid £8200 for my bullet and it was the only bike in the country I could find, I could not even find a Gen3 Levo at the time, expert was not released so the S works would have been too expensive for me to be honest. You won’t be disappointed with the way the bullet rides but you will notice the power and the range for sure. Santa Cruz are amazing bikes and the brand is super cool, however Specialized are nothing to sniff at having had many of them over the years. I had always wanted a SC and it’s scratched that itch.
I seldom ride in Turbo, mostly eco when I am solo and trail with Dom and co.
Hope this helps
