Our speed test evaluates the Latch 2’s programming across assist levels and advertised speeds, using both torque and cadence sensors at Class 2 and 3 settings, plus the throttle. Without pedal assist, the bike averaged 7 mph.
At Class 2 speeds, the torque sensor settled at 9 mph (PAS 1), 15 mph (PAS 2), and maxed at 20 mph (PAS 3). The Class 3 torque test showed PAS 1 at 8 mph, PAS 2 at 16 mph, and PAS 3 reaching 28 mph. Switching to the cadence sensor, Class 2 speeds progressed from 7 mph (PAS 1) through 11, 14, 17, to 20 mph (PAS 5). Class 3 cadence followed a similar staircase: 12, 16, 20, 24, and 28 mph across the five levels.
A key distinction emerged in how the two sensors modulate speed. The torque sensor uses only three levels but feels responsive and intuitive, allowing easy speed control through pedal input with notably generous power delivery. The cadence sensor offers five distinct levels, each capped at a specific speed; riders cruise up to the limit and must increase the level to go faster, a common cadence-sensor approach that relies on level changes rather than pedal modulation. Both systems show linear, progressive speed increases.
The throttle, driven by a 750W motor, is peppy and powerful. It requires a double twist to engage—a customizable safety feature—but the twist mechanism felt slightly awkward ergonomically, with a thumb lever preferred even among twist throttles.
Overall, the Latch 2 is approachably programmed, delivering solid, predictable performance across all tested modes. The torque and cadence systems are both well-executed, differing in philosophy but serving rider needs effectively. The only minor critique is the throttle’s ergonomics, but it doesn’t outweigh the bike’s good results.
