Purchased used beach cruiser today frame measures 18" and it has 26" wheels.

When pedals most low position rear of my heel is dragging on the ground (unless i keep my feet horizontal) to the point that i almost able to brake with back of my foot without taking it off the pedal.

Never had this with any other bike, but i never ride cruisers before wonder if its normal or sign of having frame that is too small?

Not normal. Got a picture or the name of the bike? Roger

Sounds like the saddle might be lower than optimal, and/or the tires are skinnier than the bike was designed for.

This.

But a picture of your peddle strokes (top, middle, bottom) would be even better.

I never heard of anything like this in all my years.

It don't let me upload pictures until i have 10 posts.

Bike is Schwinn cruiser no idea what model.

Seat is not much of a problem i believe because as i was making 180 turn across the road i leaned bike and pedal dragged on the road, luckily i was pedaling so it only touched road for less than second so i balanced okay.

On flat ground distance from bottom of the pedal to the ground is 3" when pedal is horizontal and when i turn pedal 45 degree distances is 2", crank arm length measures 7 1/2".

It has MTB tires installed 26 - 1.95" wheel outer diameter including tire is 26".


Regarding the frame being too small, when i stand over the frame distance between my crotch and the frame is 3", isn't this like recommended distance for proper frame size?

The best way to tell what's wrong is to see a video of your pedal storke in motion. Otherwise, the best anyone can do is to make an educated guess.Rule of thumb. Any measurement can be modified +/- to fit your individual body dimensions, comfort and taste.

When your pedal is horizontal, it is at the same level as the bottom bracket(= crank arm axle).
If your crank arm is 7 1/2" - more than twice the stated pedal clearance when horizontal - then it should strike at EVERY revolution, unless you tilt the bike vigorously while riding.

So something doesn't add up here.

Abused step-thru frames sometimes bend in the middle, that's an option.
Regular triangle frames "never" do that.
But I suppose it's possible to splay a fork forward to drop the BB.
I'd imagine the bike would ride kinda funky though.

If you can't find a model name on the bike, do an image search on "schwinn cruiser". Scroll until you find one like yours, post link.

would it maybe have a bent springer on it or something (or maybe a regular springer that sags more than usual)? does the frame have a "foot forward" design? lay back seatpost? it's happened to me, but not on a stock/normal beach cruiser frame.

Crank arm axle center to ground is 10 1/2" i think bike is stock someone just installed longer crank arm pedals on it from a vintage bike they look nothing like cruiser.

fietsbob

size feet like a 14 shoe ?

KraneXL

My first though, then I remembered I wear size 48.

PimpMan

My shoe size is 10.5"

Swapped crank arm to 6" one now i have about 4.5" space from bottom of pedal to the ground in lowest position, got to move seat up a little though, but its not a problem.
