Torque (Nm)

The rotational force the motor produces. Higher torque means better hill climbing. Look for 80Nm+ for West Linn terrain.

WLEA Priority: Critical for our hills. We weight this heavily in Terrain Performance scoring.

Watt-hours (Wh)

Battery capacity. Multiply volts × amp-hours to get Wh. Higher Wh = longer range. A 672Wh battery holds more energy than a 500Wh battery.

WLEA Note: We test real-world range, not manufacturer claims. Expect 30-50% less than advertised on hilly terrain.

Pedal Assist Sensor (Cadence vs. Torque)

Cadence sensors detect if you're pedaling and provide consistent power. Torque sensors measure how hard you're pedaling and respond proportionally—feeling more natural and intuitive.

WLEA Preference: Torque sensors feel significantly better, especially for 50+ riders who want natural-feeling assistance.

Class 1, 2, and 3

Class 1: Pedal assist only, 20 mph max. Class 2: Pedal assist + throttle, 20 mph max. Class 3: Pedal assist only, 28 mph max.

Portland Rebate Note: Only Class 1 bikes qualify for the $1,600 Portland rebate. We flag eligible bikes in every review.

Step-Through Frame

Frame design with a low or absent top tube, allowing riders to step through rather than swing a leg over. Essential for accessibility and getting on/off easily.

WLEA Priority: We rate step-through access in our Comfort scoring. Mobility matters more than looks.

Full Suspension vs. Hardtail

Full suspension has shock absorbers front and rear. Hardtail has front suspension only. Full suspension adds comfort but weight and cost.

Hydraulic vs. Mechanical Brakes

Hydraulic brakes use fluid pressure—more stopping power, better modulation, less hand fatigue. Mechanical use cables—simpler but require more hand strength.

WLEA Recommendation: Hydraulic brakes are worth the upgrade, especially on heavier e-bikes descending hills.
