This bike is freaking awesome!

Juggernaut Ultra 1000 Pro

This is built like a tank! It will definitely outlast me with upkeep. 1000w is a lot of power. I get up my nearly 40 degree hill with no problem at almost 7mph and I’m just getting into shape.
The company has been very supportive with questions and issues. They really care and that is big these days.

Great bike. Very smooth and enough power to take most hills or terrain.

Ellis Nease
Very pleased with bike

Took delivery of my Juggernault Classic last week. Bike received some damage during shipping that messed up the front fender and put a very small scratch on the battery and frame. Customer service was extremely responsive and I just got notice today that the replacement fender cleared customs and is on the way. Additionally they are sending some touch up paint for the battery case and frame.

The bike itself is well built and I'm getting used to riding again (been several decades) . The pedal assist is a bit surprising when it kicks in and is more than adequate to climb the hills around my house and the 11% grade of our driveway. Looking forward to taking it to some local trails with flatter terrain to see how well it rides for an extended trip.


Fast shipping, arrived with no damage and easy setup. I haven't put very many miles on it yet but it's an awesome ebike. Thanks biktrix!

Juggernaut Review

I ordered both a Juggernaut Ultra 1000 Pro and a Stunner LT. Even after held up in Memphis, both arrived timely and in good condition. I assembled the bikes in about an hour each. Although I've not had time to put a lot of distance on the Ultra Pro, it performs as advertised. There is a long, steep hill nearby and it climbed easily in 3rd with a 3 assist. I've driven it across rough terrain, after which I changed the saddle. This is my first e-bike, but friends have them. The Ultra 1000 Pro is the top of the heap.

One of my top two favorite bikes of all time. Fantastic bike and components at great price

After seven year's experience with fat-tire ebikes, and multiple brands, the BikTrix Ultra 1000 PRO is one of my top two favorite bikes. The other being the Ultra FS. Great components and top-of-the-line assemly, coupled with a price that is well below the competition.

Bike is stuck on FedEx. Cryptic comments in FedEx app say bike “not scheduled for delivery”. Supposedly great customer service from Biktrix is patronizing and consistently not helpful. I am one unhappy customer.
