    Great bike that's a lot of fun!

    I decided to purchased the S05 full suspension electric mountain bike mainly based on price, style, and features. Since this is my first electric bike I was not really sure what to expect. I ordered it on Wednesday and it arrived 4 days later which was very fast, partially due to it being stocked in the US. It took me about an hour to unpack and assemble. Once assembled I allowed it to charge for 8 hours per the instruction. My first ride was on Monday morning, the day after I received it. At first I couldn't get the bike to turn on because the instruction didn't say you had to hold the mode button down for 4-5 seconds. Customer service was very fast and helpful so once I knew that everything worked great out of the box.
    I've ridden bike for about 16 miles and it works great. I got this bike mainly for exercise and the electric motor is really great when going up hills on dirt/sandy trails.
    The electric assist levels of 4 and 5 are really faster than I can pedal; however, you still have to pedal to keep the motor engaged in these assist modes so you do get some limited workout. Any time the motor is engaged in one of the assist mode (1-5) you can twist the throttle and go full electric without pedaling.
    Although the seat was comfortable at first, after sitting on it for an hour your butt may hurt. But then again, I think that's common for anyone starting to ride again after a long break LOL.
