Ya the pedal crank broke off of my bike.

I think I can get the part I need from who I bought it from (spinning.com). Just I was wondering has anyone repaired a spinner bike before? The way it connects is really different from an ordinary bike. Any website with blue prints on how to fix them?

I took some photos.

Contact Jeff Wimmer at www.studiocycles.com. He is the indoor cycling repair guru. Which bike do you have? The home version? That BB doesn't look anything like what I use on my Schwinn and StarTrac Spinner Pro bikes.

Gojohnnygo.

I agree, the BB looks funny, maybe a cheap copy. What kind of bike is it? The cranks look like the steel replacements for the star-trac Vbike, But not the BB?

The damage looks like the bike was rode with a very loose BB or crank arm bolt and spun it's self out.

If you feel the cranks rocking back and forth, Don't ride you could hurt yourself.

Like demoncyclist said www.studiocycles.com is a good place. even https://www.sportsmith.net/

When looking at your first pic it looks like you sheard off the crank bolt. Due to a loose crank arm bolt.

Gojohnnygo.

The easy way replace the BB and crank arms.

Uh, what does BB mean?

Its a Johnny G Spinner Home Edition.

BB= bottom bracket- the spindle and bearings that connect the cranks to each other and alloews them to turn smoothly. How did you shear that thing off anyway? I would think that a home use Spinner would get far less abuse than those at a club. Are you doing your calf stretches on the bike? If so, you are putting too much stress on the pedals and spindle. That is the only thing I can think of that would put that much stress on that part.

Well I do do it standing up and I'm about 200 pounds.

Uh, ya it went crooked, and then it just came off...

Uh okay, where would one buy a normal square taper BB spindle?

Also how hard would it be put it all together?
