Battery purchased

Wow what customer service they went and measured one of there 48v short battery’s for me. it worked perfect on my other brand fat bike which only sold a 10.4amp battery but the bike comes with a 20 amp controller so 17amp is great almost double the range

Still waiting

A lot of promises - disappointed by their fallow through. I am still waiting for my spare battery that I paid for and replacement of a non-operational sensor!

Sorry about that Patrick. We see that your battery was delivered 5 days after you ordered. Did you not get it! https://www.purolator.com/purolator/ship-track/tracking-details.page?pin=331468832661

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.
