Great for kids not ready for bigger powerful bike
Very sturdy and will put together bike. We added a bag for the rear rack and a bottle holder. My son has so much fun with this and gets great exercise. No problems going on 20 mile rides as far as battery. I wish there was more pedal assist speed levels. Acceleration is smooth and manageable for anybody.

Great for teens!
This is a decent bike for someone who wants to purchase an electric bike for the first time without having to spend over 1k! I got this bike for my son and he loves it! He enjoys riding it to and from school and he loves that it has lights on it for night riding
