I’m fairly certain 24” was common for DH biking many years ago.
Ive ridden 24” bikes and find them similar to riding a 26” bike.
I also appreciate that anything that’s folding and larger than 24” is not going to be a compact fold anymore.
This is what makes the Helix so appealing. It’s the largest practical tire size with the smallest practical folded size.
dang...I wish they would just release the darn thing. Next week another’s update right?? Nothing this weekend.
