When you are looking for the best cadence for your 20x4 foldable bike, or any bicycle with square tapered crank shafts for that matter - look no further!
The 63 teeth chainring is the largest you can mount on the foldable fat bikes so you can still fold it and the bike will rest on the foot, without the chainring touching the ground.
The 63T offers 19% better cadence than the stock 53T chainring and combined with the 11-34T freewheel (or cassette on some models), will improve the cadence by 38%! That is massive improvement! No more ghost-pedalling.
