Description: HJMBIKE uses a Shimano gearing system and thumb shifter. The shifter on the right side of the handlebar controls the rear derailleur, which moves the chain from cog to cog, changing the way the bike rides. Shifting down to a lower gear moves the chain to a larger cog. Shifting down before slowing or stopping the bike can help make it easier to start pedaling again. Lower gear, easier climbing. Shifting up to a higher gear moves the chain to a smaller cog. Shifting up can help a rider propel the bike farther and faster with each pedal stroke, but will require more effort from the rider. Shipping Information: Free shipping on orders over $69, orders under $69 will have different shipping costs depending on the size and address.
