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
