    Hey Guy's,
    My A50 bike I built for my son has been chugging along since replacing the bad Mag.
    What happened now is the chain broke. I looked on bikeberry for a replacement but I'm seeing several types of chains.

    Which one will work on the A50 setup?

    Once again, Any and all help would be greatly appreciated

    110 link - 415H is what comes with the kits

    a #41 industrial can be used if 415H is hard to get where you are

    You could also run 410 bmx chain. If your engine or wheel sprocket is too wide you could remove some material from the sides of the teeth to make it fit. Lightening any rotating mass on the bike allows quicker acceleration.

    Most kits, at least Skywawks, used 410# in the kits way back when.

    I just don't get all the problems some seem to always have with 415#.
    If you get your back sprocket aligned with the engine sprocket and mounted true and use intelligent tensioner placement with stock parts i have over 40 builds like that here.
