E Bike Fix a Flat

FIX A FLAT

Remove wheel
• Front: undo axel nuts and remove from E bike
• Rear: shift into smallest cog in rear, undo brake clamp then axel nuts; remove
• Rear: set bike upside down on handlebars and seat before removing nuts (caution: Motor wire protrudes out from left side of axel. You do not need to remove wires to change a flat. Wheel can be removed but it cannot be seperated from the bike by much distance.)

Deflate tire
• Remove remaining air by depressing valve
• Schraeder is larger, spring loaded valve and must be depressed; car style valve
• Presta is all-metal, air sprung narrow valve; unscrew then press

Remove one side of tire from rim
• Using tire levers, unseat one side of tire; start away from valve stem
• For tight rim/tire combinations, multiple tire levers are needed; do not use metal levers
• Many mountain and hybrid bikes tires will come off by hand; practice at home

Remove tube
• Remove tube from tire; avoid valve damage by starting away from valve
• Keep tube and tire in same relative position to each other to aid in finding puncture
• Inspect tube for hole; mark for patching or use your spare tube for replacement

Inspect inside of tire
• Feel inside of tire for the cause of flat; use caution as the cause may cut your finger
• Remove thorn, glass, staple, nail or whatever caused your flat
• Inspect tire for damage caused by flat

Install new or patched tube
• After repairing damaged tube or retrieving spare, inflate tube to give it round shape
• Fold back tire to allow access to valve hole; insert valve first then tube into tire
• For presta valve, screw valve closed and install valve nut loosely against rim

Reseat tire bead
• Start reseating tire by hand at valve hole; work in both directions
• Push valve partially back through rim to insure proper seating of tire bead
• Visually inspect tire bead to insure proper tire seating on rim

Inflate tire
• Inflate tire slowly, checking for bulges which might indicate improper bead seating on rim
• Deflate if bulge occurs; carefully re-inspect and reseat bead on rim
• Inflate to desired pressure

Install on bike
• Front: install wheel; tighten axel nuts making sure that front disk rotor is positioned in the middle of the disk calipers; make sure the wheel is straight
• Rear: install wheel by placing chain on top and bottom of small cog
• Rear: push pulley closest to you forward; drop hub down into frame and tighten. Reattach brake.

Ride away
• Check brake and hub quick releases; make sure that tire does not rub brakes or frame
• Check rear derailleur to make sure that shifting is still smooth
• If anything is wrong, the wheel is probably crooked; make sure wheels are in straight
