Thunder review

I've had the Thunder for about 2 weeks and I like it. Its my first E-bike so there is a learning curve. Assembly was easy and straight forward. Make sure you go through EVERY bolt and Allen **** and not just the ones you have to assemble. I ride it to 16-20 miles a day to work and back and with all throttle and no pedaling the bike is usually at 30-40% when I get home. Obviously it would go up if I do pedal assist. The seat isn't the most comfortable. The biggest downside I've experienced is flat tires. In 2 weeks I've had 3 flats. My city doesn't have the cleanest bike lanes but the website says "puncture resistant"---I know that doesn't mean "puncture proof" but the tires have not "resisted" punctures lol. I bought liners to go in-between the tire and tubes and it helped for the front tire but the back tire is still going flat. I think its a learning curve replacing the tubes but I do wish they already came with a liner or something more heavy duty for a turn key bike that you can enjoy for months without having to service it. Taking the rear tire off was a little scary but once you figure it out its not so bad.

Overall I'm happy, just need to get the tires to hold air so i can enjoy it!
