J7ggernaut duo awesome

Great riding and dual batteries are long lasting. Thanks

Range Extender Battery

The Sale and Delivery was Awesome. The Installation was good, It is very difficult to actually install the battery onto the mount plate, the upper end of the battery hitting the step over bar. I am planning on removing the extender battery tomorrow, so I can bring it inside for the winter, I am sure this will be a difficult task. I did not get a chance this Fall to really give the extender battery a real good test, Spring will be here in 6 months, so next year I will try it out.

My teen has been riding her bike to school from Mosier to Hood River, OR, about 15min each way and over some steep hills, with no problem
