I purchased 2 rad minis and have been happy with the bikes. My partner and I didn't ride them together as much as we would have liked the 1st year, so one bike got far more use than the other. After 14 months one mini had only a little more than 50 miles on it. At that time, it's battery died. The battery claims to charge up, but has no juice at all when put back onto the bike. I've tried all the usual fixes from RAD (changing fuses) and have had no luck (other than not being able to help me replace the battery, the support has been good).

I am forced to pay for a brand new battery to get this bike running again ($500) because I was out of the 1 year warranty. Very disappointed in the reliability of this battery. Maybe I just got a lemon, but feel that the company would do better by their customers if they updated their warranty to include a mileage specification. Just like a car engine. Something like, "warrantied one year or 500 miles which ever comes first". A dead battery after only 50 miles of use is really unacceptable and I wish that they could provide some support for my case. I provide this testimonial as a data point for those researching these bikes. I hope that my case is the exception and that I was just one of the unlucky ones.
