    I order this for my Mongoose Malus based off of anther purchasers recommendation. I received my order and found that there was a problem with one of the bearings. I reached out to the team at Sick Bike Parts and they took care of me in no time. No Hassles, just Great Service!

  3. Suitable for Mongoose Malus 5 Star Review

    Posted by on 07 01 2020

    Have a Mongoose Malus and the stock spindle threads got messed up. Tried to find a direct replacement, but due to COVID-19, Mongoose support is currently hugely backed up. Couldn't find anything suitable for the Malus as the BB shell is 110mm, and other options look to require me to re-face the bb shell. That is, until I came across this listing. The images looked nearly identical to what came with the bike, so I figured it was worth a shot and ordered one.

    What arrived actually seems nicer(?) then the ad images, as the product I got seems to have a beefier spindle and sealed bearings on either end. It also uses a 20-spline tool to install the cups, vs the pin style YST cupset I had installed previously. Installed it and it seems fine, but have yet to take the bike for a spin. It seems to pedal much smoother/with zero play (although this is with no load as I have some other stuff to fix first).

    I do want to note that it didn't seem to come with a lock ring for the non-drive side, but that might be due to not needing one on an motorized bike for whatever reason? I might honestly also have installed it incorrectly, but we'll see. I ended up just using the lock ring from the previous bb cups I had and it seemed to install fine. Ordered a second one for a spare for my brother and his Dolomite.

  6. Perfit replacement for my Fat tire electric bike 5 Star Review

    Posted by on 08 22 2017

    I purchased this item to replace a bent bottom bracket. The item fit perfectly and the bearing slides on the shaft to fit each custom need. I recommend this product to anyone needing this for a fat tire bike.
