Engineering Excellence in Electric Mobility

About Qulbix

Established in 2012, Qulbix is a world-registered brand specializing in high-performance electric bikes and motorcycles. Headquartered in Slovenia, EU, Qulbix was founded by Mitja Šorn, a mechanical engineer with over 25 years of R&D expertise in the automotive and motorcycle industries.
Between 2001 and 2008, Mitja’s work in elite R&D departments (Akrapovic, Rotax) contributed to the development of components for Moto GP, Superbike, and Motocross projects. This deep-rooted experience in prototyping, CAD, and reverse engineering—including pioneering one of Slovenia’s first 3D rapid prototyping services—forms the foundation of every Qulbix frame. We combine racing-grade innovation with precision engineering to redefine what an e-moto can be.

design and prototyping

Our design philosophy is rooted in continuous improvement. Based on insights from previous models, we established new, ambitious goals. Whether the objective is more power, less weight, extended range, a removable battery, or any other innovation, our iterative prototyping process allows us to rapidly develop and refine solutions to meet and exceed these challenges

Engineered for Resilience

Testing is where the Qulbix reputation is earned. Our test riders put new designs through a brutal "destroy" phase—simulating years of heavy-duty abuse in just a few months. This process allows us to identify and eliminate potential weaknesses, ensuring that every component we ship can handle the demands of everyday hard riding and beyond.

production

Having successfully addressed all previous engineering challenges, the bike or component is now move-in ready for full-scale production. While manufacturing has begun, our commitment to excellence is constant: we continue to subject our latest designs to rigorous testing, ensuring that every new breakthrough or refinement is immediately integrated into the final build.

Qulbix hystory

models Timeline

The first model, FR1

2012

Those times when electric bikes are still mostly unknown to the general public. Qulbix (then under a different brand) becomes one of the pioneers of performance electric bikes.

Model Q165R

2013

This design enables the mounting of a large li-ion battery pack to power the bike, giving it a much longer range. Frames doubles as a structural part of the vehicle and a protective battery box.

Model Q140R

2015

Lighter and narrower then its predecessor, with an even bigger battery box. Qulbix becomes an international registered brand of electric bikes.

The Q76R

2016

The Q76R is developed for riders who are looking for a lighter, narrower bike. The number 76 indicated the width of the bike’s frame (in mm). This is the first model wit two types of seats – moto and bicycle seat, which are easily interchangeable.

Q76 MD

2017

Q76MD is the first model, where the electric motor is no longer located in the rear wheel. This marks the end of the hub motor era and marks the beginning of mid-drive electric bikes for Qulbix.

Q140MD - gen 1

2018

The first version of the Q140MD - a mid-drive performance electric bike is launched. The motor is now placed at the centre of the vehicle, which minimises un-sprung mass and effectively improves the over-all performance of the bike.

racing

2019

The Qulbix Team begins racing in e-bike cross sport and takes golden medal in the first ever FIM World Cup in Imola, Italy.

racing

2020

Other racers start competing with the Q140MD Core and take first four places in the Italian National Championship in EX-Bike Cross.

Q140MD - gen 2

2022

A new version of the Q140MD Core is launched, featuring all the little tweaks and improvements based on racing feedback – the front wheel changes, the moto seat becomes longer and with harder padding, the controller is moved to the inside of the frame, making the bike even more dust and water resistant. Core is still available in multiple set-ups: pedals/foot pegs, moto/bicycle seat.

Q140MD Core L1e-B street legal

2023

Qulbix launches its first ever street legal model, the Q140MD Core L1e-B which is intended for the wider audience, not just racers. The new bike has all the features of its racing ancestors, but is locked into moped, so it can be easily registered and ridden anywhere.

q155/Q80/q140md with qulbix removable battery system

2025

The Next Generation of Performance. We’ve overhauled our entire lineup with the launch of the Q140MD (Gen 3), the all-new Q80, and the Q155—the powerful successor to the legendary Q140R. Every new model now features our proprietary QRBS (Quick Release Battery System), offering expanded capacity and lightning-fast swaps to keep you riding longer.
