The folding mechanism is designed to have a certain amount of resistance for safety reasons. 

We do have some tips that will make it easier for you:

To open the scooter we suggest placing it on the floor and putting one knee on the deck. Hold the hand grip in one hand and wrap your other hand around the black plastic lock release cuff near the bottom of the handlebar.  Now slide the cuff in the direction of the grips until you feel that the locking mechanism has released.  Let go of the cuff and open the scooter until the handlebar locks in the upright position. (IMPORTANT:  If you are having trouble getting the black cuff to slide, just wiggle the handlebar up and down a little as you pull and the cuff will start to slide. Please do not force the cuff to slide.  Doing so may cause damage to the folding mechanism.)

Repeat to fold the scooter.  If you are having trouble getting the black cuff to slide, just wiggle the handlebar backwards and forwards a little and the cuff will start to slide.

SAFETY WARNING:  Before riding your folding MICRO kickboard, please always ensure that the handlebar has locked into the upright position.  Failure to do so may result in the scooter folding while riding.
