Marcy Onyx B80 Indoor Bike

[martypshill]

Hi, I am hoping that I can get some help here.

I purchased this bike approx one month ago. The right hand pedal does not screw in to the crank arm (I think it's called). It is definitely the correct pedal as the left one is in correctly. It looks like there is a problem with the threading on the right crank arm. It looks slightly damaged. So the pedal does not screw in.

Would you know of a solution for this at all? I have looked in lots of places online and have found nothing. Would I need to buy a new crank arm?

I have contacted the seller, long story short, I got a refund, but got to keep the bike! So, I really want to fix it if I am able too!

Thanks!

You can get them re-threaded.

If you can get the black end cap off it looks like a square taper crank. It'd be easier to replace it with one the same length.

Have a look at this:

Right hand crank is #49.

I would say this is not a square taper: look at this:

Thanks folks

I got this fixed, but now the pedal is making a loud cranking noise. I was going to get replacement pedals.

Anyone know if these are 1/2 or 9/16 pedals?

Take a pedal off your road bike and present it to the 'ole.
