Mongoose Paver 700c
 

I really love this bike, I've had it for a few months, I know it's nothing special, but I had a Californian Mongoose when I was a kid, and got this for cheap. I know it's not a great bike, but I like the frame and it's a fun ride to and from work.

What I need to do: replace the bottom bracket, the crankset, and the chain.

I found a Bucklos crankset that I'd like to get for it, but I'm not sure on the bottom bracket. I can't find anything regarding what I would need to get in terms of size for it. I was hoping someone here could give me an idea of what I need. I haven't replaced parts on a bike in a long time, I remember how and have done it many times, but that was 20+ years ago lol.

Any help would be appreciated. I know I could just go out and get a better bike, but I'd like to make this one work for a while.

I would move on quickly. You can get a brand new bike with all the same common problems from Wally-mart and similar places for the price you will pay to get this one fixed. You could also save up money and get a bike that is more practical for commuting.

If that many things are damaged and need replacement on a few month old bike that is a bad sign and will just lead to pumping a ton of money into something worth $10 new (I didn't say cost but value)

Mongoose is really no longer the same Mongoose that made the cool IBOC frames and fun old BMX stuff.

Bucklos cranksets to fit hybrid bikes like the Paver are available in two types: square taper and what Bucklos refers to as "Hollow Integrated." The latter is newer and is based on Shimano's Hollowtech II design. Either type should be compatible with your bike.

The Paver's bottom bracket shell is undoubtedly threaded and the English/BSA type, which is as standard as it gets. Measure the shell (it's either 68 or 73 mm in width), and order the correct bottom bracket for the crankset and the shell width.

Once you know which bottom bracket you'll be installing, check the bottom bracket type that's currently in the frame and look at YouTube videos that demonstrate how to remove that type. Then, if the new bottom bracket is the other type, look for videos on how to install it.

Note that you'll need some bike-specific tools to remove the pedals, cranks, and bottom bracket. If the new cranks are not the same type (square taper versus hollow) as the old cranks, you'll need additional tools to install the new bottom bracket. Which tools are needed for each type will be explained in the videos.

here's a vid from another Paver Owner...


the Crank arms on the stock bike are Cast Iron, weight a ton, rust quickly, and have been known to get loose...i've seen one broken one, not too long ago, and a few with bad pedal threads... the bottom bracket is also junk waiting to fail. they rust easily, and love to get loose. they rarely have enough grease, or a good setup, from the factory...

the first thing i'd change would be that crank and BB... look into any reported failures of the Bucklos cranks... they've had serious quality issues around bucklos, but are trying to improve things...
measure the frame's bottom bracket to begin your search... report what you find here.

the crank i'd get for that bike would be a Shimano HT2.... they make a wide range of them, in both 68 and 73mm styles.
Here's an example... ebay Search: Shimano CUES FC-U6030-1 Gravel & Road Crankset 42T, 165mm, Asymmetric 110BCD,

$75... count the teeth on your present chainring, and get that frame's BB measured.


the hubs and steering bearings need to be gone thru too... many are nearly devoid of grease, and the front hubs' bearing adjustments are almost always too tight from the factory.....

replace the chain soon, or you might find out why breaking a chain is never comfortable.
a KMC X8 or SRAM 830 chain will be appropriate

While I appreciate the love of a bike, I parted one of those out some time ago. I'd be hesitant to spend the money on a new crank knowing the quality of the rest of the bike.

was the frame still solid, unbroken, and usable?

i've parted out, revived, and upgraded a few dozen mongooses over the years... and they always sell fairly quickly

a walmart bike won't bother to revive or upgrade? Kent, heavy steel framed versions, or any walmart bike of any brand with the name :"Glacier ... " on it.
