I’m a passionate bike rider for local transportation in Boston, but live on top of a steep hill. This has been a little intimidating when considering a bike, rather than car, errand. However, this kit (which was very easy to install) is exactly the right answer. Without using the motor, the bike looks and operates like a bike. The extra wight of the motor and battery are hardly noticeable in most circumstances. But when I need that boost up the hill, or when carrying a lot of cargo, that boost is just right. I still have to pedal, but don’t have to kill myself. Thanks.
