The Schwalbe Marathon E-Plus embodies absolute excellence for electrically assisted bicycles: designed specifically to meet the demands of high-speed e-bikes (S-Pedelecs up to 50 km/h), this 28-inch tire combines maximum puncture protection, exceptional grip at high speed, and outstanding longevity. ECE-R75 approved and E-50 certified, it is intended for demanding cyclists seeking total reliability on long distances and intensive daily commutes.

Technical Summary

The Marathon E-Plus 28x1.50" (40-622) is part of Schwalbe's Performance Line range and stands out with its "flat-less" design dedicated to electric bikes. Weighing 990 grams, this wire bead tire incorporates the German manufacturer's most advanced technologies: Smart DualGuard double protection (level 7), specific ADDIX E compound, reinforced TwinSkin carcass, and "anti-age" sidewalls that durably resist damage. Its modern and dynamic HS498 profile offers remarkable versatility for touring and urban as well as suburban trekking.

Technical Highlights

• Smart DualGuard — Level 7 puncture protection: The patented 5 mm thick SmartGuard layer made of special rubber is reinforced by two high-resistance RaceGuard textile plies. This double defense protects against punctures from sharp objects (glass, flint, tacks) and guarantees maximum safety even in intensive use.
• Exclusive ADDIX E compound for e-bikes: Developed specifically for electric bikes, this compound offers remarkable grip even at high speed, optimized rolling resistance, and exceptional durability. It meets the increased thermal and mechanical demands of electric motors.
• Reinforced TwinSkin construction: The new carcass architecture incorporates an additional textile layer on the sidewalls, stabilizing the tire for increased load capacity (112 kg maximum). The "anti-age" sidewalls prevent cracking related to prolonged use at low pressure.
• E-50 approval (ECE-R75): Certified for S-Pedelecs and high-speed electric bikes up to 50 km/h, this tire meets the strictest European standards for safety and performance. Also compatible with standard e-bikes (assistance up to 25 km/h).
• Versatile HS498 profile: Modern and dynamic design with optimal tread depth for touring and trekking. The tread pattern ensures balanced traction on dry and wet roads, while efficiently evacuating water.
• Fair Rubber commitment: Schwalbe pays a fair premium on each kilogram of rubber used, contributing to improving the living conditions of small producers and their families. An ethical and responsible approach.

Geometry and Standards

The 40-622 format (ETRTO) corresponds to the designations 28x1.50" (inches) and 700x38C (French). This tire fits rims with 19 to 25 mm internal width and allows inflation pressure from 3.5 to 6.0 bar (50-85 PSI). With its 67 TPI construction, it offers an excellent compromise between rolling comfort and structural robustness. Schwalbe inner tubes 17, 18, 19, and 19A are perfectly compatible.

Performance and Longevity

The Marathon E-Plus positions itself as the most puncture-resistant tire ever tested in the e-bike segment, while maintaining surprisingly smooth rolling thanks to high-tech materials. Independent tests (Bicycle Rolling Resistance) confirm controlled rolling resistance (27.4 watts) and an exceptional puncture resistance index (163 points). The average observed lifespan regularly exceeds 5,000 to 8,000 km depending on usage conditions.

Recommended Use

Ideal for urban cyclists and bike commuters using high-speed e-bikes, long-distance touring enthusiasts on e-bike touring bikes, professional electric bike couriers, and all users seeking absolute peace of mind against punctures. Integrated reflective strips enhance visibility and safety at night. Compatible with all types of approved E-25 and E-50 electric bikes.
