Blix Ultra is the ‘Monster Truck’ of Ebikes

My latest review comes courtesy of Blix Bikes. They sent me the Blix Ultra a large dual battery 26×4 fat tire ebike with a monster rear rack. This ebike is the biggest bike to date I have tested and it measures 80 inches from tire tip to tire tip!

It is large and in charge.

It sells for $1,849 at (single battery) while the dual battery version goes for $2,249. Blix was founded in Santa Cruz, CA in 2014, and offers offers various e-bike models including city, cruiser, cargo and folding ebikes.

Blix Ultra Ebike Review

I had a couple of issues out of the box which I had to address before riding. First, the front hydraulic brake was not working at all. I brought it to my local bike shop and they quickly diagnosed the problem, The hose that houses the mineral oil was twisted at the connection point thus pinching it and not letting the fluid drop. They had to replace the hose and re-bleed the line.

Second issue was the rear fender which is somewhat loose. I had to add a zip tie it to the rack to keep it steady and raise the clearance over the rear tire.

Bit once I got past those road blocks the Ultra came to life. It comes as a Class II ebike but with their mobile app I was able to update the ebikes firmware and switch to Class III mode which unlocked the speed to 28 MPH. Unfortunately you have to use the app each time you ride to switch to Class III. The app resets each time.

The frame is gorgeous and I just love the sloping lines of the top tube … its so polished you can’t even see where the welds are.

  • Thanks to the two foot long rear rack and available accessories it’s essentially an “off road cargo ebike”.
  • Comes with quality parts, good fit and finish.
  • Top speed is 28 MPH and can be adjusted to class 3 speeds only within the app.

When you get up close to the Ultra you can tell its a beast of an ebike that is worthy of the monster truck tagline. That rear rack is two feet long and those fat tires will run over anything.

It’s size also means its better suited for bigger riders. It is a substantial ebike and probably weighs around 80 pounds with the rear rack installed. I can see it being the perfect ebike for rural living and places with lots of dirt roads that still need to carry some cargo. It is geared well with an 11-32T cassette and hits 28MPH effortlessly thanks to the 750 watt motor.
