EXOS : TYRE MAINTENANCE

Flat Tyre

If you get a flat tyre, remove the wheel. Depress the tyre valve to let all the air out of the tube. Remove

one bead of the tyre from the rim by grasping the tyre at a point opposite the valve stem with both hands

lifting and peeling one side of the tyre of the rim. If the bead is on too tight for you to unseat it with your

hands, use tyre levers to lift the bead carefully over the tyre rim. Push the valve stem through the wheel

rim. Remove the inner tube.

Carefully check the outside and inside of the tyre for the cause of the puncture and remove the cause if it is

still here. If the tyre is cut, line the inside of the tyre in the area of the cut with some handy-tape, a spare

patch, a piece of inner tube, or whatever will keep the cut from pinching the inner tube.

Either patch the tube (follow the instructions in your patch kit) or use a new tube. Reinstall the tyre and

tube. Slip one tyre bead over the rim. Insert the tube valve through its hole in the rim. Feed the tube

carefully into the cavity of the tyre.

Inflate the tube just enough to give it some shape. Starting at the valve stem use your thumbs to seat the

tyre bead inside the rim. Work your way around both sides of the wheel until the entire bead is seated in

the rim. Be careful not to pinch the tube between the tyre bead and the wheel rim. If you have trouble

getting the last few inches of bead over the edge of the rim with thumb pressure, use a tyre lever and be

careful not to pinch the tube. To avoid punctures we recommend slime tyre sealant or similar.

Check to make sure the tyre is evenly seated around both sides of the rim and that the tube is inside the

tyre beads.

Push the valve stem into the tyre to make sure that the base is seated within the tyre's beds. Inflate the

tube slowly to the recommended pressure, all the while checking to make sure that the tyre beads stay

seated in the rim. Replace the valve cap and re-install the wheel.

WARNING

Riding your E-bike with a flat or under-inflated tyre can damage the tyre, tube and E-bike, and can cause

you to lose control. Please ensure that your tyres are inflated to the correct PSI indicated on the tyre
