How to Replace the Inner Tube

How to Replace the Inner Tube

The inner tube is a consumable component of an electric bicycle that may need to be replaced when you have covered a certain distance or frequently ride in challenging terrain. You can follow the procedure I provide here or watch our instructional video on YouTube for guidance.

 Please watch the video for replacing the front or rear wheel before you remove the tire that requires the inner tube replacement.

Tools: Tire lever, multifunctional Allen wrench



Step 1: Unscrew the valve cap and use a tool to press against the valve to release the air until it's completely deflated.

Step 2: Use a tire lever to pry off the outer tire.

Step 3: Remove the old inner tube.

Step 4: Inflate the new inner tube to a suitable level. Then, position it correctly inside the tire.

Step 5: Insert the outer tire back onto the rim.

Step 6: Inflate the tire, pumping it until the inner tube is about halfway filled with air. Check if the safety line on the outer tire is approximately 1mm away from the rim and evenly distributed.

Step 7: Fully inflate the inner tube, pressing firmly to ensure it is adequately inflated.

    I purchased a RV3 off Amazon in April 2023.

    I had problems with the handlebars not tightening . I had a new bike stem sent and , I put it on and it got a little better. But , the handlebars still will move when I hold the front wheel in place. It’s not safe to ride .

    I’m guessing it’s on me to repair it and I’m taking it to a bike shop to repair it. Unless you have a solution. I’m still waiting for a $30 Amazon card that your representative said he would send me. For a bent kickstand I replaced on my own.

    Hope you guys have a solution to make things right. I’m not going to pack it up and send it back then wait 4 months for you to repair and send back.
