Bonnell Electric becomes first eMTB OEM to equip bicycles with Tannus Armor from the factory.
Bonnell Electric, a leader in high-performance electric mountain bikes and lightweight electric motorcycles, has announced a groundbreaking partnership with Tannus America, becoming the first e-MTB manufacturer to factory-install Tannus Armor tire liner on production bikes.
The integration launches with the Bonnell 775 MX, which now ships with a rear Tannus Armor liner pre-installed. The result is a ride experience that delivers superior puncture resistance, enhanced rim protection, and virtually eliminates flat tires: an industry first for OEM eMTB production.
"Flat tires and damaged rims have long been a frustration for riders pushing the limits. By integrating Tannus Armor directly into the 775 MX, we're delivering real-world performance and reliability that riders can feel from day one."
"It's another example of Bonnell engineering solutions that make riding more fun and worry-free," Wauters added.
Tannus Armor is a multi-density foam liner designed to sit between the tire and tube, providing 360° protection against punctures and pinch flats. It enables lower tire pressures for improved traction without compromising rim safety, which is particularly vital for high-torque, high-weight electric mountain bikes like the 775 MX.
"Bonnell's decision to include Tannus Armor from the factory shows a deep understanding of the eMTB customer: someone who values performance and reliability without compromise."
"Our partnership with Bonnell sets a new standard for OEM integration," Crowther said.
The 775 MX, known for its category-defying design that blurs the line between MTB and lightweight moto, already delivers exceptional torque, control, and handling. Now, with Tannus Armor installed, every 775 MX rolls out of the box ready for serious trail duty. No upgrades needed.
The best anti-puncture solution for your bike.
Tannus Armor is an insert positioned between the tire and the inner tube, drastically reducing punctures and maintenance. Its patented multi-density foam liner provides full tire and rim protection while allowing lower pressures for greater traction.
The Bonnell 775 MX with factory-installed Tannus Armor is available through Bonnell's U.S. dealer network and direct-to-consumer channels beginning November 2025.
