Paul Debban
I purchased this battery with my new Roadster V3. It nearly doubles the range as expected. It is a good vale when compared to range extenders for competing brands and works well, with the extender compleminting the built-in battery. I recommend that you ride the bike before purchasing the range extender and determine if you need the extra range. The range of my Roadster V3 without the extender is very close to the advertised range. Also, read the installation instructions before you buy. Installation of the range extender can take longer than the assembly of the bike itself. There was a stripped screw on a cover plate on the bicycle that made installation more challenging. The last comments are on the item itself. If you remove the range extender for charging, the cable that attaches the battery to the bike is recessed, making the cable difficult to remove. The holder for the battery has a couple of design issues, the flexible strap that retains the battery sticks out and can rub on your leg while peddling. The water bottle holder screws that come on the bike are not recessed in the holder and rub on the battery case. Overall, this is a worthwhile upgrade if the standard range is not adequate. The extender works well, with a controller that shares the load between the extender and the primary battery. There are some small implementation issues that could be improved, mostly with the holder that comes with the extender.
