    Dorado Batteries

    I purchased a Dorado Battery for my Stunner X from Biktrix. Hasmik from the Customer Support Team was excellent in assisting me purchase the correct battery at a fair price and shipped it promptly.

    Nor sure Battery was the issue

    We purchased the new battery as our Stunner would just shut off under mild load. We purchased the new battery which arrived timely and as described, however our Biktrix Stunner still shuts off. while riding.

    Smooth and thorough return and repair process

    I needed my back wheel rebuilt. There is an online form Biktrix uses for shipped repairs. it requires a lot of detail but really it is no more than what this sort of thing should require. The online process was seamless. I got my wheel back in a couple of weeks and the repair was done perfectly.
