I'm running a 49cc huashengtaishan 4 stroke on a 21" (2005)Schwinn Mesa.
It's a tight fit on my old school mountain bike, but, the only problem I'm having with that is that I only have one side for pedaling. The side with the 3 sprocket crank is holding me up.
Does anyone know if there's a way to extend the lower bracket? I've called bike shops, and have researched it online with no answer.

Hi. Thank you for your post. I'm wondering if those cartridges are for fat tire bikes specifically? because they have much bigger lower brackets than a regular mountain bike

Should be both there, depends on how wide you need them, try calling them, they have just the shaft also...........Curt
