    Well, sometimes bigger IS actually better!

    I received the new 20 Ah battery for my Juggernaut Ultra, and suddenly worrying about having enough battery power for the return trip is not longer an issue. I did my best to see how long it would take me to run it down to a 50% charge by using throttle-only while in Level 5 sport mode. I rode for more than 2 hours, but only managed to get the battery down to 83%. I clearly did not set aside enough time for that little experiment, but it sure proved to me that I made a wise choice getting the big battery. I also have an 11.6 Ah battery that came with the bike, but I'll just use that as a backup - not sure I'll ever need it though. Get the biggest battery you can afford - you'll be glad you did.

    Extra Battery

    This is a perfect replacement or extra battery in my Biktrix bike. It also fits another brand electric bike I own that needed more range and wasn't supported by that company.

    Spare 19.4 AH 48 volt battery

    It was a pleasure dealing with Roshan as a person and Biktix as a company. I contact Roshan about a spare battery and he followed up with dimensional information so I could verify the unit would work in my "other brand" bike. I ordered and received the unit, it fit perfectly and gave me increased range. The only mistake was my own in that I should have originally bought a Biktrix bike! Good service and honest answers and good value!

    20 aH battery

    The battery was delivered quickly. We haven't had a chance to spend a lot of riding with the new battery, but power so far is excellent.
