Quality machine

Can’t wait to use this bike on some expeditions. Just waiting for the snow and freezing temps to disappear. You can tell this bike is well built with quality parts. It rides amazing around town and so far I’m super happy. Looking forward to riding it hard in the near future.

Ultra Beast

This is my first electric fat tire electric bike. It is a tall beast really fun to ride so far no problems and it was easy to assemble.

Hannah Gifford
The Beast Rocks

We bought a Juggernaut Ultra Beast and it is correctly named. This is our 6th electric bike and we couldn’t be happier. Stop shopping elsewhere and buy a Biktrix, you’ll be glad you did.

Carlos Perez
Juggernaut Ultra Beast

Love my e-bike it's great, though I had a surprise when I put it together it's a hell of a lot bigger in person than in the pictures, it almost looks like a motorcycle it truly is a beast. but it's a great e-bike very comfortable, great ride no regrets here love it.
