    Need cranks for this fatbike

    Help!

    bike in question(specs)

    I own what I suspect to be a 2015 era Charge Cooker Maxi. I purchased some pedals to upgrade and have ended the upgrade process with an unusable bike. It seems to make these cranks fit the fatbike, they spread the crankarms out and then used some kind of thread insert to aim the pedals so they don't behave like bent pedal axles do, wobbling your foot around.

    I removed the pedals, which were not easy to thread out then started trying to thread the new pedal in. When it didn't want to go, I tried the other pedal with the same experience. I decided not to press my luck and tried to install the old pedals but they didn't want to go in either. After an hour of trying, I threaded it all the way through forcefully, not realizing that I was supposed to be trying to thread the pedal in at an angle to the crank arm and not in a perpendicular plane and now I have fully threaded pedals that are so "bent" that the bike is unrideable. Whatever thread insert was there has been gobbled up and now will no longer accept the pedal in the correct angle.

    After this, I found a review online where the reviewer talked about the ingenious way the brand managed to repurpose a standard crankset by flaring the arms out. I'm sorry but I am unable to currently find the article as it was on another computer.

    So now I own a bike I can't fix. I was wondering if someone might know of a cheap set of cranks I can get for this bike to move the components over to. I'm afraid just finding the correct spec cranks will cause me to have cranks whose arms are too narrow to clear the chainstays.

    I'm lost without my ride. Please help!

    Did you install the pedal on the correct side? Pedals threads are directional and can only be installed on one side or the other, not both

    Also, post a pic of the issue.

    I had the same bike, cranks arms are parallel and are nothing special.

    Hi there and thanks for the help!

    The pedals threads were oriented correctly. Common thread on left foot, bass ackwards on the right.

    I'm pretty sure a vid might work better to explain my issue but I'll do my best to figure out a way to explain the issue in an image.

    I found the article that makes me worry I might not find a replacement crankset:

    Itís achieved this by cutting down on the specialist kit. To give enough clearance for the 4in wide tyres, the extra wide bottom bracket does require special cranks, but theyíre FSA Comets matched to SRAMís X7 group, so you get a full 2◊10-speed setup with a normal range of gears, just like on your trail bike. Instead of a super wide spacing on the rear hub, it uses a standard 135mm rear hub at the back and one of matching width up front.

    It's most likely a standard FSA Comet Fatbike-crank and you just cross-threaded your pedals in.

    Measure bb whidth, chainline and q-factor, and you should be able to find something that works. Or take it to a bike shop and ask for help.
