Juggernaut 1000 Ultra

Wow just wow. I’ve never ridden this much in my life. These bikes are game changers. My son and I are averaging about 30 km per day. Just a joy to ride. Great job Biktrix.

Kira Ahrens

Was lovely, I would definitely buy from them again

Mitchell Laurio

Great bike , love it and so does everyone else!

Russell Gold
Ultra 1000

Using it is really enjoyable. It is a big machine, wildly different than the old beach cruiser. Once the order was shipped, it took 4 days, I was shocked, stunned and excited! Great pace.

The only problem I had/have is the box arrived with oil on the shock side of the package. The bike has air shocks, so the assumption is that it came from the carrier somewhere. Honestly none have said to me the shocks do not have oil. I have no idea if they do or not.

After that small complaint, which is minor, I love this bike.

I’m 65 years old and I purchased the Ultra 1000 and it’s the perfect bike for me. I use it on and off road and I could not be happier.

Jeff Sorensen
Juggernaut ultra 1000

I'm an active 72 year old who lives in a small town in the sierras,ca. With lots of hills. This bike has allowed me to get back in the saddle and enjoy riding again. This is a high quality bike with tons of power. If your considering buying this bike, don't hesitate. Thanks to the folks at Biktrik for making a great product. I'm having a blast! Jeff

Juggernaut Ultra 1000

I have had my Biktrix Juggernaut Ultra Fat Tire for about two weeks. It is an amazing ebike. I have been able to ride up mountains hills in my area without much effort at all. Have already done a 40 mile loop around my lake the ebike was amazing. Just can't wait to get up in the morning and go for a ride.

Ultra fun

This bike is awesome!! Fun,fun ,fun !!! Just so happens my neighbor just bought a little folding e bike, he brought it over to show me , I said that’s not a e bike this is a e bike, as I opened my garage door! He looked like a porn star that just got out of a ice cold pool! Only it was his ego that had shrinkage! Thanks biktrix team keep up the good work!(no pun intended 😁

Travis Miller
Great bike!

Took about 2 weeks to ship from Canada to the US even with weather delays. I use this bike as a daily commuter and I love it. I was worried about the learning curve of shifting at speed with a mid drive but the shift sensor, motor controller, and rear derailleur all work flawlessly to provide smooth shifting even with the throttle pegged. Do this at your own risk though. The motor is very powerful. This bike is not a speed demon, it's a torque monster. It chews through battery life at high speed. 25-30 mph with a head wind it goes through 5-10% per mile. Throttle only. This thing eats hills for breakfast. Pedal assist 1 lowest gear just stand up on the pedals and it'll pull you through any hill your tires can get traction on. I haven't done a long range test yet and I've been making the bike work hard so I'm sure I'll get more and more efficiency out of the battery as the new ebike excitement wears off and my enjoyment of pedaling returns. Get two batteries! Great work Biktrix! This things a game changer for me.
