This is the first e-Bike that I have owned. I am really enjoying the bike. Pros- hydraulic brakes, PAS, manual throttle control, powerful motors. Cons- lack of rear suspension, 3 sprockets at pedals (you only need 1 large one), battery life, and key switch (on handlebars). After riding a few miles, you will understand the need for rear suspension. Your rear end will be very sore. I added a Safort seat spring stem for about $90, replaced seat with RockBros seat $20, and added a gel seat cover for about $12. Much better ride now. I also added a handlebar riser stem (130mm) for $25 to help with posture. The next thing I missed when researching these bikes was the front sprockets. The largest one on this bike seems a little small to me, and with the throttle to help starting off, you just need one large one. With the largest sprocket, you are ghost-pedalling at PAS3. That means you cannot pedal fast enough to go faster. You can only use the throttle at that point. As for the battery, you will have to pedal a lot to get the advertised mileage. In reality you get about half the miles or slightly less. My last complaint is the key switch. You will hit your knee on it occasionally. That needs to be relocated. That being said, I really am enjoying the bike. I have over 120 miles on it now. If you are considering an eBike make sure you read up on bike classes and laws in your area!
