Tecnium 90/90-19 Tubes for Surrons and Dirt Bikes

Built for 19” off-road wheels, this Tecnium 90/90-19 inner tube (also equivalent to 3.00/3.25-19) is a solid upgrade for Surron-style e-motos and lightweight dirt bikes. The TR4 straight valve suits most 19” MX and enduro rims, giving you an easy fit with common 90/90-19 and 3.00/3.25-19 knobbly tyres used on front or rear wheels.

Manufactured in quality butyl rubber with a standard-duty wall thickness, this replacement tube is designed to hold pressure consistently and cope with the repeated hits of trail riding, enduro loops and track days. Match the tube to your tyre sidewall markings (90/90-19 or 3.00/3.25-19), pair it with a suitable rim lock where required, and you’ve got a dependable inner tube for everyday off-road riding and e-moto commuting.
