Discover the Schwalbe Smart Sam Plus at BIKE24
The Schwalbe Smart Sam Plus adds extra protection to an all-round tread that's equally at home on forest trails and city streets. The Plus stands for Schwalbe's Double Defense construction, with added protection under the tread and along the sidewalls. It's made for riders who commute during the week, hit the gravel on weekends and don't want to change a tube by the roadside. Picture an after-work ride: ten miles of bike path, a rooty stretch through the woods, then coarse gravel on the way home. The compact center tread rolls smoothly on asphalt, while angular shoulder knobs bite when the surface gets loose.
Why choose the Schwalbe Smart Sam Plus
Three features set this tire apart from basic all-rounders: puncture protection, versatility and the right approval for e-bikes.
- Double protection: GreenGuard under the tread and SnakeSkin along the sidewall.
- E-bike approval: ECE-R75 approval up to 45 km/h for most sizes.
- Visibility: A continuous reflective strip improves side visibility at night.
Schwalbe Smart Sam Plus tires at a glance
All Smart Sam Plus tires share the same tread pattern, rubber compound and puncture protection, with differences in wheel size, width and e-bike approval. Wider MTB sizes suit more off-road riding, while the narrower 28-inch tire is better suited to asphalt. The series builds on the Schwalbe Smart Sam with increased puncture protection.
Schwalbe Smart Sam Plus in 26, 27.5 and 29 inches
The MTB sizes from 2.10 to 2.35 inches wide form the core of the series. Their higher volume lets you run lower tire pressures, smooths out roots and ruts, and provides confident traction on loose ground. They're well suited to hardtails and e-mountain bikes. The 26x2.10 size carries the E-25 designation.
Schwalbe Smart Sam Plus in 28 inches for trekking
In 28x1.60 and 28x1.85, the Smart Sam Plus becomes a touring tire. The narrower profile rolls more easily on asphalt, while the tread pattern carries you across dirt roads and wet forest trails. These sizes are well suited to trekking bikes and commuter e-bikes. The 1.60-inch size is approved for pedelecs up to 25 km/h.
Schwalbe Smart Sam Plus in 20 inches
The 20x2.35 size brings the series to the smaller wheels found on folding and compact bikes. Its high volume helps compensate for the reduced comfort of the smaller wheel diameter and absorbs impacts from curbs. ECE-R75 approval makes this size suitable for fast compact e-bikes.
Schwalbe Smart Sam Plus technologies
Three elements define the tire: Double Defense construction with GreenGuard and SnakeSkin, the Performance Line ADDIX compound and e-bike tire approvals. Together, they create a tire designed to rack up miles without demanding much attention.
Double Defense on the Schwalbe Smart Sam Plus
Double Defense protects the tire in two key areas. Under the tread, a 3 mm GreenGuard layer made from special rubber, some of it recycled, helps stop glass and thorns before they reach the tube. SnakeSkin adds a lightweight fabric layer along the sidewalls to protect against cuts. That means fewer roadside stops.
ADDIX Performance Compound from Schwalbe
ADDIX is Schwalbe's family of rubber compounds. For the Performance Line, Schwalbe uses a compound that prioritizes durability over the last bit of grip. It remains supple enough for wet conditions but wears slowly, even under the torque of a mid-drive motor. In everyday use, that means plenty of tread left after a season of commuting.
ECE-R75 and E-25 on the Smart Sam Plus
Tires on motor-assisted bikes face greater loads, so Schwalbe tests them to specific standards. ECE-R75 indicates approval for fast pedelecs up to 45 km/h, while the E-25 designation covers pedelecs up to 25 km/h. Most sizes carry ECE-R75 approval, while two sizes are marked E-25. Check which approval your bike requires before ordering.

Frequently asked questions about the Schwalbe Smart Sam Plus
What size Smart Sam Plus fits my bike?
Check the sidewall of your current tire for the width and wheel size, such as 54-622 for 29x2.10. Use these dimensions when choosing your new tire. You usually have some flexibility to go wider or narrower as long as your frame and fork provide enough clearance. If you mainly ride off-road, choose one of the MTB sizes. For daily commuting, the narrower 28-inch tire is generally the better fit.
Can I run the Smart Sam Plus tubeless?
No. The Smart Sam Plus is a conventional clincher tire designed for use with an inner tube, not tubeless use. This makes installation and roadside puncture repairs simpler because you don't need sealant. Add the right tube to your order so you're ready to ride once the tire is installed.
Does my e-bike require a specific tire approval?
S-pedelecs up to 45 km/h require ECE-R75 approval, and a tire without it isn't approved for this vehicle class. For standard pedelecs up to 25 km/h, the E-25 designation is sufficient. You'll find both approval types within the series, with the applicable designation listed in each tire's product name. Check your e-bike's documentation before buying to make sure you choose the right tire.
