    Need help with wheel size

    This is my friend's bike from the 80's. It had been in the back of her mom's house for years... I asked her if I could refurbish it for her daughter and she said to go nuts with it.

    The problem is that I threw the wheels away and I don't remember what size they were. Any help figuring out the wheel size would be greatly appreciated.

    looks like a typical 20" wheel (by estimating the BB in relation for scale)
    Honestly... ahh I give up

    I'm thinking it's an 18". Check with Russell and see if he has any extras over at Dream Bikes.
    Authorities speculate that speed may have been a factor. They are also holding gravity and inertia for questioning.

    my 20" wheels with tires measured 9 3/4" from the center of the axle to the ground. measure your fork and see if it will fit.

    i am guessing it will be 18 inch wheels too.
    everything sucks but my vacuum cleaner.

    haha, yeah - I think you guys are right - I took a known 18"-wheeled bike; olerlayed and aligned/resized to match BB shell diameter
    Looks like a good match

    Thanks. Based on the feedback, I'll install a new wheelset and new white colored tires and pedals. Hopefully this little frame will outlive us all, not be neglected, and it will be a generational bike for a bunch of little kids in the future. Like a passed down light saber.

    I like what you did. I already have a new saddle. New grips. Just need the wheels. I already have a white KMC chain. I hope they take care of it.

    So when you're driving the "Ice Cream" van you'll have that in the back next to the duct tape for when you forget to bring the puppy...

    That must be one of your sick and unfulfilled fantasies.

    This is for dear friend of mine and her little girl.

    That looks great! Nice touch with the white chain.
    I don't believe anything, but I have many suspicions.

    From what I understand, the 18" wheel on BMX bikes was actually brought to market by accident. I have been told a certain mfr brought in a few containers of 20" bikes in from overseas w/ really short top tubes. The CPSC would not let them in because the toe overlap was too much. The fix was to make the wheels smaller to increase T. O. distance and they sold. Now Co's make them specifically w/ 18" wheels.

    Is there a point to this?

    Yes. I'll bet if your bike is designed for 20" wheels, you miight be able to mount 18" wheels on it without issue. Pedal clearance drops a little, but it probably will work either way.

    Very nice restoration -- way to bring it back from the dead.

    Head to Home Depot for some plastic/rubber caps for that rear axle. While chicks dig scars, they don't necessarily dig 'em on themselves.

    That bike is nice, but it will never climb like a 29er ... good job. Can I drop off my old 26" SS with fake gas tank?

    you could totally fit 20" wheels on there, give up the kiddie wheels and get some grown up wheels. it's not just a fad 20er's are here to stay.

    I'm sorry you took that so seriously, I meant it as a joke, even if it was a sick joke.

    Nicely done gift for her.

    I couldn't sleep for weeks. I wandered the Wisconsin high desert near the border with Montana...

    I was over it about a couple of seconds after your comment

    Really cool that you reposted the finished product. I remember seeing this when you were mid-project. You did a great job! She'll love it.
