Rail (750Wh) '23/'24 Rail Gen 4 Sizing Dilemma

[GravityDT]

Cheers All,
New to emtb's and looking to get electrified and I'm smack dab between the MD and LG for the new Gen 4 Rail. I'm 5'9.5" w/ 32" inseam, looking to get the bike to explore rougher backcountry zones where it has been more moto/equestrian trails, ie bit steep, loose and technical. Solid expert level rider and coming off a '23 Santa Cruz Hightower V3 sz LG which has a 475mm Reach. It feels decent to me.... Looing at a few slightly used '23 Rails online both in a MD and a LG. For the riding conditions I mentioned above, would we want to go a tick shorter than what I'm used to or a bit longer??

Unfortunately the opportunity to throw a leg over both is not really an option with both being out of my area

TIA

For that height shorter. Get a medium and a longer stem.

I'm 5'10 and sized down to the medium, sitting at 460mm reach now and couldn't be happier. The large is nearly 490mm!

I currently ride a medium Gen 4 Rail. I'm 5'9.5" w/ 32" inseam also. The stem length was 60mm but I reduced that to 45mm along with a carbon bar cut to 760mm. The geometry seems right for my body size even though I have a long reach. I don’t think I would be comfortable with a large size Trek Rail.

I heard that when in doubt…size down.

I'm 5'9" and ride a medium. There are times when I think I could have gone for a small.

Thanks All for the input. Thinking of pulling the trigger on a MD, now I need to convince the CFO.....

Shorter. You dont need to be as stretched on an e-bike and shorter will be more fun and playfull. Ps. I'm 5'11 and ride 450 reach Voima.

180 cm with Large 9.9 gen 4. Would not have wanted Medium. Came from a 9.7 gen 2 (2021). Barely noticeable difference in size

1m77 on a medium Rail Gen 1 with a shorter stem and more rise on the bars for better gnarability.

… for better gnarability.

How in the world did you get past ‘spell-check’? Mine keeps spelling ‘gardening ’. .

Bar rise adjustment definitely helps and it’s easy to do.
