Puncture Resistant Tube

Puncture resistant tubes, sometimes called thorn proof, have an outer wall that is three times as thick as a standard tube (see the cross section photo) and this extra thickness dramatically reduces the risk of puncture.

In our experience they will decrease your chance of getting a flat by more than 95%. They also hold air much longer than standard tubes, usually only needing to be inflated once every 6-8 weeks.

The downside is they cost and weigh a lot more, so we only buy them in E-bike sizes because the extra weight is not felt and punctures are a bigger hassle than normal.

They typically weigh around 200g more than a standard tube, about half a pound per tube of additional rotating mass on your bike.

These tubes are the best choice for heavier and difficult to change e-Bike wheels. 

This size fits our most popular models, the Aventon Pace & Level as well as the Rad Power RadKick.
