The tubes are made to last, but punctures do happen. The easiest first step is to seal the hole with a tube sealant available from your local bike/trike shop.
There are 2 styles of tubes to consider
(a) one with an angled valve stem fits in the aluminum colored wheels (2011 – 2019) for use with any schrader pump.
(b) straight valve stem fits in the black colored wheels (2020). May require a stem extender for easy access.
