Thicker 40% 14 x 2.125 Inner Tubes Heavy-Duty 14 Inch Electric BikeTubes for Replacement Electric Scooters and E-Bike Tire Tube 2 Packs

These are great for my daughter E-bike - other tubes would not last very long and would require her to reinflate every week or so. These retain the air; are durable and are a great value price wise. I would recommend changing out e-bike wheel tubes for these ones, you won’t be disappointed!

Great

Great tube. I'd had issues with others going flat after short usage but after placing this tube in I've had no flats.

I've ordered 2 sets of StaiBC tires of the 14x2.125 for electric E bikes. Each time I've had issues with small manufacturing/pinhole defects that have caused me to change out 3 flat tires within the past 2 weeks. Onto my 3rd tire, aired it up, crossing my fingers but I'm not impressed.

Package looks good.. quality is satisfying.. butt I didn’t use them yet.. but the both tubes looks high quality..

Ok

One tube was good, the other had a slight hole and didn’t hold air. The good tube is really spot on and holds air very well, need to work on quality control.

Nice look good
