Rad Power Bikes Radster Trail

Buyer highlights

• Natural assistance. A torque sensor adjusts motor support in response to pedaling effort.
• Class choices. The display can switch among class 1, 2 and 3 settings, subject to local rules and route restrictions.
• Mid-fat tires. Three-inch tires balance cushioning and mixed-surface traction with less bulk than many 4-inch fat tires.
• Published range. Rad lists 65-plus miles under its test conditions; route, assist level, load, speed and weather will change actual range.
• Safety equipment. The current model includes hydraulic disc brakes, a 200-lumen headlight, rear-facing turn signals and a UL-certified electrical system.
• Theft deterrence. A fob or personal code can lock the controls, though a physical lock and secure storage are still needed.
