2024 Stromer

ST3 ARBR Edition

A highly refined speed pedelec with near-silent motor, regenerative braking, and premium integrated lights. The ST3 Pinion features an internally geared bottom bracket with 9 speeds, a 568% gear ratio, and can shift at standstill. The Launch Edition (LE) features special edition metallic red paint and a red Gates Carbon belt drive that is clean, durable, and quiet.

Top of the line touch points include Ergon saddle, GS1 locking grips, and wide aluminum alloy platform pedals. Custom Pirelli tires offer volume and width for comfort, stability, traction, and puncture resistance. Optional WREN inverted suspension fork with matching fender and suspension seat post take comfort to the next level. Optional anti-lock brake system.

Brake light activation and LED running light with integrated USB charging port are unique and useful. Extra large battery pack extends range but fills fast with the included 4.5 amp charger. Onboard electronics include 4G cellular communications for remote locking, tracking, and over the air updates. Optional smartphone app lets you tune the motor.

The sturdy frame, large battery, and powerful motor all combine to make the bike heavy, but the weight is well distributed front to back. The center-mount kickstand can create pedal lock if left deployed when moving the bike around. It would be nice if the wires and cables could route through the frame itself vs. the external plastic channel below the downtube.
