Have to admit, my wife is smarter then I am. I rated the purchase as a one star, as it was just charged for the first time yesterday, when I received the bike back from Eric's Bikes, and once charged, wouldn't turn on. I thought the rear light was great. Loved the ability to change the light settings. I told her this am, the light didn't appear to work, and showed her that the light wouldn't come on, and she said it probably takes a long push. She did it, it came on. She loves it, especially the three light settings on the front light. I bought her a Pace 350 for Christmas 2 years ago, and this year bought the light kit, a front and rear fender, a back rail, a handle bar storage bag and a rear expandable bag for the top of the rear rail for Christmas for her this year, from you. Took it all into Eric's, and they did the installation on all. I apologize for the one star rating, as it's no longer valid. Seems to have been a good purchase after all, and one I would now admittedly do again. Just a thought though. Any chance you might consider coming up with a 40 mile battery for the Pace 350? My wife, doesn't drive, and takes this bike everywhere. She rides it to farm where we board horses, and it's a 10 mile one way trip. Now, she can take the charger with her, but it would be so much nicer if she could rely on having enough battery power to make the return trip without worrying about it dying on her. Thanks.
