Versatile all‑round MTB and e‑MTB tyres with smooth on‑road rolling, confident off‑road grip, and a heavy‑duty Plus version for maximum puncture protection.
DESCRIPTION
The Schwalbe Smart Sam (HS624) and Smart Sam Plus (HS624 PLUS) are popular, versatile all‑rounder tyres designed for riders who split their time between paved roads and off‑road trails. Both feature a modern tread design with a compact centre ridge for smooth, low‑vibration rolling and edged outer blocks for stable grip on loose terrain.
Smart Sam (HS624)
The classic, fast‑rolling all‑rounder. It balances on‑road efficiency with off‑road traction, making it ideal for everyday commuting and light trail riding. E‑25 approved for pedal‑assist bikes up to 25 km/h. Puncture protection varies by production line, typically using Schwalbe’s standard K‑Guard or basic protective layer.
Smart Sam Plus (HS624 PLUS)
The premium, heavy‑duty version engineered for higher puncture resistance. Favoured for E‑MTBs and cargo bikes that encounter tougher terrain and debris. E‑50 approved for fast e‑bikes up to 50 km/h. Equipped with Schwalbe’s Double Defense system: a 3 mm GreenGuard layer under the tread combined with SnakeSkin sidewalls for maximum flat prevention.
