    Range extender does not work

    I recieved the package and installed it but have yet to get a resolution from the support team. They have been very responsive but it still does not work.

    No range anxiety!

    When I rode my juggernaut FS XD and I took the riding to work route. With my old bike, when I got to my work, I had to plug-in the battery for at least an hour and a half before I went back home. This time I did the full route and still had 50% left! This range is great and I love not having range anxiety!

    OEM GARBAGE

    I purchased the duo OEM backup battery a little over a year ago. The first battery I received did not charge. I was made to prove to them that it was not charging before. They would send her a replacement and I had to pay for shipping. The second battery I received Worked for the first few months. I hadn’t used it for a few months, but kept it charged… I thought. When I went to use it, it had no charge and was unable to hold a charge. In other words, both batteries were faulty and a complete waste of money

    Juggernaut XD Range Extender

    Hello, I really like my Juggernaut XD, it’s just that I have a challenging commute and I need more battery. I bought the XD expecting the range extender to be available soon after buying. Well, I was happy to be informed that the design had been completed so I ordered. I was told “plug and play” but the 11 step directions said that a qualified person needs to install. Being a bike mechanic from the 80’s and 90’s I reluctantly decided to install. I basically got to the end but could not stuff all the wires, connectors, XT-60, etc. back inside the frame. I cannot get my original battery back in the back so I have decided to go to a reputable local bicycle shop to see if they can help me. I am hopeful but it has been a challenge. So, my beautiful XD is resting awaiting to be revived. When this is all done, I hope to write a better review. Most everyone at Biktrix have honestly tried to help. More to come.

    Great purchase

    Prompt delivery. Excellent customer service. On two separate occasions I called and it was off hours and I did not leave a callback message and the next day they spontaneously called me to ask if they could help me

    New Battery

    I ordered a new extended range battery from Biktrix as I’m planning for a few extended day trips this summer. Curtis quickly got my order in and I was surprised and pleased that it was on sale for $200 off the regular price. It was shipped and got here quickly with no issues. Thanks Curtis and Biktrix!

    Nice addition

    The main battery gets good mileage, however I would suggest going with the extender. It fits nicely and can still use the step thru.

    Don’t know if they work.

    Installed correctly, but no indication if they work or not. Nothing on the computer screen. Rode 37 km with both turned on but got down to 2 red bars, just the same as if I only had 1 battery. Used pas 1 100% of the time. No instructions or advice on what to expect from the company and no easy to find (did not find any) links to show how they work.

    Great to have plenty of power when off the grid for week or more at a time.

    This is a handy way to have the extra power for bike use when camping off grid for extended periods. Unless you have an elaborate solar power setup, it takes quite of bit of time to totally charge up the larger batteries. It adds extra weight to the bike, but that's not a big issue for my particular use. It would be a smart idea to drill and tap a couple of holes in the frame to be able to clamp the electrical cable down, so it's not able to be snagged by brush or your foot. I ended up buying the cheaper extra battery because in haste , I didn't review the options close enough. Its not even worth trying to exchange it because of the return policies. I think that selection process could be a little more easier to understand if it were more obvious that there are two options of battery quality. I'm happy with the outcome, and know I have plenty of battery power to get me around before I have to charge everything back up. I use mine for better fishing access and exploration when camping, i don't use the extra battery a lot for just doing errands and exercise trips, the main one ( 17 AH ) does fine for that.

    Nice extender battery

    Fits perfectly and functions/meshes perfectly with the standard battery as one. The only possible weakness are the 4 firnished mounting bolts which I think should be 1/8" longer to provide more threads screwed onto the frame. So I just got longer bolts to make a more solid connection. Also the battery electrical wire connection to the frame mount is bent into what I consider to be too-sharp an angle that may weaken over time...possibly the frame socket could have been located 2" lower!?

    52v, 13AH extender battery

    The battery was sent expeditiously, well packaged and complete as described, and included a charger which can be used on my Juggernault Ultra Duo also. However, my range increased only about 11 miles which is not much ( I had expected ~20 miles more). So possibly not cost effective for $400 more... you can decide if it's worth the additional $$s for you.

    Extender Battery

    Mounted easily. works as advertised. Wish there was a better way to rout the connecter cable. Have it covered with Gorrila tape so I don't trip over it when I get on the bike.
