When I bought the rickshaw half a decade ago, the tires and tubes were already on the rim. Last weekend, I snapped the metal stem on the left rear tube. Thankfully, it had enough air trapped in it to get home, but there was no way to add more air in the future, and all three wheels have leaked a little since day one.
I went to Bikes2Boards and picked up a tube. Then, the process of solving a mystery began. What’s it like under that tire? Here’s a glimpse:
There’s a red tube! The tire is also odd. It essentially goes all the way around with a cut down the middle so a tube can fit in. The uncommon backside of the tire ends up functioning as the tape for the inside of the wheel, which has no tape at all.
Getting the 26 x 1.75 tire off and back on is a serious challenge. It can be done, but it is a difficult process. You have been warned. A nice change is that the wheel now has a common (in the US) Schrader valve. No need to use a Presta to Schrader valve adapter anymore.
