Flat Tire Defender - FTD II E-Bike 27.5" & 29"


FTD II E-Bike Tubeless Race


Why are FTD II so important for E-Bike mountain bikes: E-Bikes are heavier, sustain higher speeds and carry more load on tires and rims.

FTD II E-Bike is 40% wider to maximize rim protection and dampen out suspension harshness on rough terrain, 30% taller to maximize tire sidewall support and allow lower tire pressure for increased traction, light weight to minimize rolling resistance and un-sprung weight, excellent high quality foam rubber based material (no pool noodle here). All this at a very affordable price!

Based on Flat Tire Defender field testing, we’ve found on average, tire pressure can be reduced approximately 10% from a tubeless tire pressure without foam inserts.
