Propella has announced the second generation of their 9S Pro model, the 9S Pro V2. This is a Class 1 commuter (20 mph max speed, no throttle) that comes in both a traditional frame as well as a step-thru frame. The Propella 9S Pro V2 is unusual among e-bikes in this value-focused tier of e-bikes. It retails smack-dab in the middle
of the $1000-$2000 price range, but it sports a collection of features that would be more in keeping with an e-bike priced above $2000.
The Propella 9S Pro V2 is light for a commuter e-bike, weighing just 43.5 lbs., which is an impressive achievement for any e-bike. They manage this by making a number of strategic choices with regard to components. First, there’s the 350W brushless, geared hub
motor. As we’ve mentioned in reviews of other sub-50-lb. e-bikes, when an e-bike weighs less than 50 lbs., a smaller motor (like this 350W unit) can offer terrific performance because it doesn’t have to accelerate as much weight.
