You want your son's stand-over (flat footed measurement from the ground to the crotch) to be around 2 or 3" more than the bikes stand-over dimension (dimension L). Then with your son's stand-over requirement, you may have better luck searching for the bike. You may find that if your son is tall, a medium size bike would fit better. You really don't want a really long seat tube sticking out of the bike frame. And maybe the medium size would work better has your son is still growing. |
The long seatpost seems to be the thinking in most MTBs.
His cousin has the Marlin 5, which is up-spec a little bit on the same frame, so I’m pretty confident on the sizing.
