Yes, we know rubber.

Ask a regular bike rider if they’ve ever had a flat. “Oh, yeah! And, it always happens at the wrong time and the worst possible place.” But beyond the potentially dangerous mishap of getting a flat, think of the cost—new tubes could easily set you back $200 or more over a 5-year span. So, we’ve put together a product that goes beyond what others offer. We believe in our product and we’re willing to prove it.

Why PERAM™ ?

The PERAM Smart Tube is US patent pending (15/600,212, 29/604,562). Made of sophisticated rubber composition, the Smart Tube is designed to provide a maximum protection of your air tube tires from getting flats.

It was our goal to offer a solution to riders everywhere – flat tires!   And, we’ve done that.  We have created a unique rubber composition that performs far beyond expectations.

  1. Offers the option of a softer PSI in the air tube, while maintaining a harder PSI tire surface. The softer the air tube, the greater the effectiveness against pinch flats.
  2. Special rubber properties which resist heat.
  3. Provide puncture resistance. Most debris will not penetrate the thickness of the tube.
  4. Combines the ride of conventional pneumatic tubes with the flat resistance of the Smart Tube
  5. Allows PSI adjustment for changing terrains.
  6. Reduces the possibility of broken spokes (as compared to solid or hard air tubes).
  7. Promotes longer E-Bike battery life due to a harder tire surface, and improved comfort through better shock absorption.
