Key Features

E-Bike Ready (E-25): Specifically designed and tested for e-bikes with pedal assistance up to 25 km/h. The E-25 rating ensures the tyre handles the additional torque, weight, and sustained speed of electric-assisted riding safely and durably — the most important criterion when choosing a tyre for your pedelec.
Addix Performance Compound: Schwalbe’s universal compound for the Performance Line. A highly durable rubber with a wide performance range — excellent grip, low rolling resistance, and long service life across road and off-road conditions. Specifically formulated to handle the extra demands of e-bike use.
Perfect road and trail compromise: Fast-rolling centre knobs for efficient rolling on tarmac and gravel, combined with aggressive side knobs for confident cornering on dirt and loose terrain. The Smart Sam does it all.
Distinctive Black/Bronze colourway: The warm bronze sidewall gives the Smart Sam a premium, retro-modern aesthetic that complements any bike build — from sleek urban e-MTBs to adventure trail bikes.
Wire bead (Drahtreifen): Robust and reliable — the steel wire bead provides a secure, consistent fit on the rim. Extremely durable for everyday e-bike use.
29 x 2.60" (65-622 ETRTO): The generous 2.60" volume rolls over obstacles more easily, provides more traction, and delivers a more comfortable ride — ideal for e-MTB use where comfort and control are paramount.

Frequently Asked Questions (FAQ)

What does the E-25 rating mean?

The E-25 rating means this tyre is specifically designed, tested, and approved for use on e-bikes with pedal assistance up to 25 km/h — the standard speed limit for pedelecs in Europe. E-bike tyres must meet stricter requirements than standard tyres because e-bikes are heavier, generate more torque, and are ridden at sustained higher speeds. Using a non-E-rated tyre on an e-bike can lead to premature wear, reduced safety, and potential warranty issues. The Smart Sam E-25 is the safe, correct choice for your pedelec.

What is Addix Performance Compound?

Addix Performance is Schwalbe’s universal rubber compound for the Performance Line. It is a highly durable compound with a wide performance range — similar to Speedgrip, it delivers an excellent balance of grip, rolling resistance, and longevity. For e-bike use, durability is especially important because the additional motor torque and weight accelerate tyre wear. Addix Performance is specifically formulated to handle these demands without sacrificing grip or rolling efficiency.

Is the Smart Sam suitable for both road and off-road use?

Yes — the Smart Sam is designed as a road and trail all-rounder. Its tread pattern features fast-rolling centre knobs for efficient rolling on tarmac and gravel, combined with aggressive side knobs for grip in corners on dirt and loose terrain. It is the ideal tyre for riders who mix commuting, gravel paths, and light trail riding — particularly on e-MTBs used in urban and peri-urban environments.

What is the recommended tyre pressure for the Smart Sam 2.60"?

The maximum pressure is 3.0 bar (43 psi). For most e-MTB riders, a pressure of 2.0–2.5 bar provides the best balance of comfort, traction, and rolling efficiency. Heavier riders or harder surfaces may benefit from pressures closer to 3.0 bar. Always adjust based on your body weight, terrain, and riding conditions.

What is the difference between the Black/Bronze and Black sidewall versions?

Both versions are identical in performance, compound, E-25 rating, and specifications. The only difference is the sidewall colour: the Black/Bronze version features a warm bronze sidewall for a premium, retro-modern aesthetic, while the Black version has a classic all-black look. Choose based on your personal style and bike build. The bronze sidewall is particularly popular on bikes with gold or copper accents, or for riders who want a distinctive, premium appearance.

What is the difference between a wire bead and a folding bead tyre?

A wire bead (Drahtreifen) uses a steel wire to hold the tyre on the rim. It is heavier than a folding bead but extremely robust and reliable — ideal for everyday e-bike use where durability matters more than weight savings. A folding bead uses a Kevlar or nylon cord, making the tyre lighter and packable. For e-bike commuting and trail use, the wire bead Smart Sam is an excellent choice for its durability and value.

Can I use this tyre on a non-electric bike?

Yes. The Smart Sam E-25 is fully compatible with standard (non-electric) bikes. The E-25 rating means it meets the higher standards required for e-bikes, but there is no downside to using it on a regular bike — you simply benefit from a more durable, well-engineered tyre. It is an excellent choice for any 29" MTB or trail bike where road and off-road versatility is needed.
