I've just got a new BMX and tried to ride it and the crank feels really easy to push unlink my old BMX where it had a bit of a push this one feels like in gear 1 on a Mountion bike what can I do it want it to be a bit tighten so harder to push down on

Ps the chain is tight
Thanks Adam

Gear ratio? 25 to 9 or 44 to 16 is where you want to be.

Count the teeth on your sprocket and your rear cog/freewheel, and see what your current "gear inches" number is.

As mentioned, 25/9 is really common, and it gives 55.5 gear inches. 44/16 X 20 = 55.
