Can't decide between high step or mid step radmission.


New Member
I'n interested in buying an ebike, but I can't decide which size to get for the radmission.

I'm about 5'10 with a bike inseam of around 32 inches.

I see people say they are 5'6, 5'8, and 5'9 with 30 inch inseams or less and they ride the high step comfortably. I've also seen a few people say they are 5'9 and that the midstep is too small, while other people who are 5'11 say the midstep is fine for them.

I contacted rad support and they recommended the midstep for me, and my measurements seem to make me think I would need an 18 inch bike, and that a 21 inch bike would be too big, but I have no idea.

I'm confused on which size it is I should get. Any help?

Also, is the frame size for the radmission high step 21.5 inches or 20 inches? It says 21.5 inches on the website, but the electric bike review says it is 20 inches. Which is it?

Thank you.

According to RadPower website, "The high-step frame offers a 31” standover height for riders between 5’7” - 6’4”, while the mid-step frame has a 28” standover height for riders between 5’2” and 6’2”."

If you're 5'10", either one would be fine.
