What does it mean that the Blackbird has the 750 Watt Cassette Version?
A cassette is the type of gears installed on the motor. It is a bit more expensive but is a higher quality type of freewheeling mechanism and gearset.
What makes the suspension better?
Vastly superior air fork with adjustable compression, damping, travel, etc. It does not have a fork lock out.
How do the brakes compare?
Many other ebikes on the market use a mechanical brake. We use a hydraulic brake setup with larger rotors and 4 pistons.
In short, this means you could stop the brake with a single finger - Imagine power brakes in a new car vs manual brakes in an older classic car, and less adjustment required.
