What should determine getting the 18 inch vs 20 inch frame.
1054527
I am 6'3" and my wife is 5'9" and we both have the 20". Her seat is about two inches above the frame. I would guess 5'7" is the cut-off, and anyone shorter should probably go for the 18" bike. Since the frame angles down, there is no problem for any height standing over the bike. I hope this helps.

Hi, It really has to do with your body size and what you are comfortable straddling. Per the Montague website - - Bike Sizing: 18in Frame: 5'3" - 5'10" Standover height 30" 20in Frame: 5'11" - 6'4" Standover height 31" ====== I am 5'7" with short legs and the 18 inch one works fine for me. The "stand-over height" of 30 and 31 inches, respectively can be a good clue. Measure the height from the floor to the top of the cross-bar on a mountain bike you feel comfortable riding (or straddling at a bike shop, if you have none). See if that offers any answers.

Recommend the 20" frame; 18" frame I purchased ended up fitting like a 16" frame and ended up selling the bike at a yard sale for a huge loss.

Body size.....If you're under 5'10" the 18 inch will work. At 6'3" the 20 inch is almost too small.

Hi.I went for the 20 in because I am 6ft tall inside leg 32 ins and the bike works well for me!If you buy the bike try and get the carry bag as part of the deal as they are not worth the $99 price tag!! brgds Clive

I'm 5'4 and 18inch is just perfect for me. My best guess would be for you to try both size at a local store. Or you can check online for size charts : it will tell you the recommended bicycle frame height according to your height. Under 5'4 = they recommend 18 inches

Don't do it. I have a 17' and used the 18' and it didn't fit right and now it's messed up

You can get 18 inch, 20" or 22" width, depending on model you choose. I am a broad-beam 270-pounder, and the 20" wide chair I ordered is plenty wide enough

the first size (16, 18, 20) is the size of the frame. At 173 cm height you would want the 16", that is the correct size for you. As to whether or not you can ride it ... well I can't answer that for you :P

Sorry I have been painting. inside I would go 18 wide. the unit is very heavy and you need at lease 20 inch for height.

I believe the 12' only has 6 handles. If so I would go with the 20'...don't want kids fighting for handles!

When new, seat frame is 18"apart but probably goes to l9". Arm rests are generous 13"

Yes. Go with the 17" frame. My wife is 5'-4 1/2" and it fits good, if not just a tad big for her. 5'-6" would fit it even better. NOTE: Recommend taking it to bike shop for final adjustments. I did and it rides great.

if from frame edge to frame edge is 11.8 i would get the 12", if it is less then the 10" and the legs will reach the difference

This item is only 20". You have to search the Tess 24". Before you buy this bike in 24" check out the Diamondback Lustre 24". It is a better bike that is on sale for cheaper than the Tess.

Most likely in range 16" Frame. 24" IS NOT THE FRAME SIZE...that's tire. 24" frame would be the size a 6'6"+ person would get

They're on my Model 10 and look great. What you should do is e-mail the seller and ask about returns if they don't fit. Another thing you can do is compare your Model 18 and a Model 10 and see if the frame is the same size.

No, you will be better off making one. I would hate to find a 120 inch frame! That might cost you a bit of change.

Best to measure how you are comfortable sitting. Probably the 18 or 22, depending how you like to sit.

That is tight fit...you can call us and get a small sample of frame and try it. 303-922-8998

20.5" = 52 cm, so you'd be at the end of the spectrum. Better to find one that shows 52 cm +.

It is NOT an 18 inch frame I do not know why Amazon sells it as that. The frame measures nearly 22 inches from the midpoint of the crank to the seat post insert. It is the equivalent of a 56 cm frame (i.e. Large), and best suited for riders 5'11" or taller. Hope this helps and best of luck (if you're looking for entry-level in small check out the giordano libero 1.6).
