Designed to work with all terrains, the G-force T42 provides 4” puncture-proof fat tires. It increases the tire thickness to minimize the risk of punctures.
If a flat tire happens to your rear tire, please follow the instructions below on how to remove the rear wheel and change the inner tube.
Step 1: Turn off the bike, shift to the smallest cog, and remove the battery from the frame.
Step 2: Turn your bike upside down, or lift the rear wheel high off the ground with a bike repair stand. You can proceed with it the way you like.
Note: If you decide to flip over your bike, adding cushion pads is necessary. Letting the handlebar hit the ground immediately might damage the LCD display and scratch the seat.
Step 3: Locate and disconnect the motor connector, which is on the right seat stay. Then carefully take the motor cable out of the wire harness retainers.
Note: Hold and pull the connector halves apart directly, do not twist or turn them.
Step 4: To remove the wheel from the rear dropouts, take down both rubber axle caps, and unscrew the axle nuts on both sides with the electric wrench.
Step 5: Pull open the rear derailleur and draw the chain away from the cog, then you will be able to remove the rear wheel.
Step 6: Deflate to remove the inner tube. Press down on the central pin of the valve to expel the air, use the tire levers to help pry the tire off.
Step 7: Patch or change the inner tube. A tube patch kit for regular bikes will do the job.
Step 8: Partially inflate the inner tube to check whether it can properly hold the air or keeps losing air.
Step 9: Install the rear wheel and put it back on the rear dropouts. Line up the rear axles.
Step 10: Tighten both nuts, put back the axle caps, and plug in the motor connector as per the directed arrow on it.
Step 11: Inflate the rear tire to proper tire pressure.
Note: Some sharp objects can give rise to a tire puncture. But if the tire keeps going flat, it could be due to improper tire pressure and tire care. The recommended range of tire pressure should be 20-28 PSI; you can adjust the PSI according to the rider’s weight and road surfaces, such as lower PSI for rough terrain.
