Getting plenty of power to the rear wheel is exciting, but has always come at the risk of ongoing costs in replacement parts, and time lost riding. Many casual to moderate riders will not ride hard enough to cause such issues. But for those who want to push the limits, a more robust solution was needed to build the dream e-bike machine, with extreme endurance.

The XD Drive system was developed in Saskatoon, Canada, by a team of e-bike enthusiasts with a shared passion for better solutions to transportation. The global pandemic conditions forced them to improvise, adapt, and overcome, tackling the bike parts shortages, chip shortages, shipping shortages, and forces of nature simultaneously throughout development.
The resulting product and its manufacturing approaches are primed for navigating such challenges with agility, and competitive in-house solutions.
Mid-drive motor
This in-house designed and tested motor feeds 2000+ Watts power through a direct drive secondary chain to the rear wheel. This means unmatched power, performance and durability.

Heavy duty dual drive chain
This rugged 219 chain can handle many times the forces a regular bike chain can. This chain is over-engineered for extreme durability.

Twist throttle
Unleash the power of the XD Dual Drive motor with just a flick of the wrist.

220mm rear brake rotor
The 220mm rear brake rotor along with Tektro Dual Piston brakes will quickly and reliably bring you to a halt.

BOX 4s bike-side drivetrain
The 8-Speed BOX 4S Drivetrain on the bicycle side of the bike with a 12-42T Cassette will ensure you have the range to tackle any adventures the XD leads you to!

Armageddon headlight
The Biktrix developed Armageddon Headlight with 2000 lumens of brightness will ensure your path stays lit up and fully visible.

- Pedal only (with no help from the motor)
- Pedal Assist (with 5 levels of assist to choose from)
- Throttle only (effortless like a motorcycle)
The Biktrix Juggernaut XD Duo Step-Over Fat Tire Mid-Drive eBike can be used as a normal bike where the rider provides all the power, or you can use just the throttle and let the bike do all of the work. There is also an in-between option, Pedal Assist, where the rider pedals and the motor provides a great boost at the same time. You can choose the level that is right for your type of riding. The Levels of Pedal Assist allow for increased ride efficiency, resulting in less strain on your knees while riding. It makes riding fun and effortless.
