MTD Hi/Lo "Folding Bike"

[ADVHOG]

It doesn't fold so much as it breaks down.

Seems like they only made these for a short time in the sixties.

It's kind of neat...

Thanks!

I cleaned it up a little and rubbed it down with BLO. It rides nice, like a bigger bike.

It's gonna be my shop beer runner now.

What size tires on that bad boy?

 

[ADVHOG]

It's got 16's on it.

The gear ratio is crazy...54 tooth front and 13 back.

 

[horsefarmer]

Lets see,
using 54 t front sprocket and 13 t rear sprocket (original)

54 tooth/13tooth = 4.15 wheel revs per crank rev x 16"= 66 gear inches

I usually like to keep single speed CB bikes in the 50 gear inch range.
So if you changed out your front sprocket with a common 44 t:

44 tooth/13tooth = 3.38 wheel revs per crank rev x 16"= 54 gear inches

A Wally world kids bike 32 t sprocket would yield a nice around town hill climbing ratio:

32 tooth/13tooth = 2.46 wheel revs per crank rev x 16"= 39 gear inches


Sport Touring Steep hills 27-37
Medium hills 32-42
Flat 37-47
Road Racing Steep hills 47-60
Flat to rolling 57-66
Mtn bike Steep hills 17-20
Technical trails 17-20
Dirt roads 20-27

Thanks Horsefarmer. I'm gonna copy your post for future reference!

I've got boxes of chainrings. I'll do some swapping and see if I can tame it down some.

 

[horsefarmer]

No problem. I think some of these bikes came incredibly tall geared from the factory. Maybe that's why we find them in good shape sometimes - they just were to much of a workout to ride!

Cool. How about a "breakdown" pic.
Keep original sprocket on there...
Probly get it up to 70 mph.

Here's a broken down view...

 

[Wildcat]

Nice find. All the others I've seen are Vagabonds.

 

[DJ Bill]

That front sprocket looks vaguely familiar......Roadmaster copy?

 

[Wildcat]

It looks more like a Monark chain wheel. Roadmasters like that were skip tooth, nearly the same design though.
