11 Reasons Why Qulbix Frames Are Best for the Job

Crash Resistance

Are you one of those rides who ride hard? Even crash sometimes? No worries – the Qulbix frame can take it. It may suffer some dents and scratches on the surface, but that won't stop you riding. You can't say the same for »plastic cover« tubular frame designs or carbon fiber frames.

Handling & Geometry

A great bike is much more than just two wheels with a frame in between. Geometry matters! Our frames are carefully designed in such a way to insure that the bike will steer and handle with ease and precision. BB height is perfect for rugged terrain, so you don't need to worry that you'll bottom out on a rocky trail. Our bolt-on rear shock bracket with three holes allows lots of combinations for fine tuning the rear end suspension. We understand not all rides are the same. It doesn't matter if you're very tall or kind'a small - you'll be able to set up your bike to fit you perfectly.

Super-strong Swing Arm

The Qulbix swing arm can take the torque from the high performance motors with ease. For extreme torque set-ups dropout reinforcement brackets are available as add-ons.

Modification Potential

Need to tweak, add or modify something? An additional hole for the cable or to mount a new kind of controller? Not an issue, drilling a small hole in your Qulbix frame will not compromise it's integrity. You can't say the same for carbon fiber frames.

11 Reasons Why Qulbix Frames Are Best for the Job


Qulbix frames are fully enclosed and thus IP54 waterproof. All cable inlets are sealed with silicon rubber grommets, well protected from water when riding on wet terrain. So no worries if you splash over some puddles, your electronics will stay dry. You can't say the same for »plastic cover« tubular frame designs.

Battery protection (against mechanical damage)

The strong monocoque frame will protect the battery in case you crash. You can't say the same for »plastic cover« tubular frame designs or carbon fibre frames.

Battery Fire Hazard

In case you decide to use cheaper LiPo hobby battery packs and you are concerned for the safety of your property, Qulbix's fully enclosed steel and aluminium frame will contain or limit the potential battery fire outburst better than any other frame design. Other frame types - epoxy resin (carbon fiber) and plastics will even intensify the fire. But be advised: Qulbix does not take any responsibility for the fire damage! We STRONGLY suggest you use safer cell types and always handle all kinds of batteries carefully, safely and in accordance with instructions!
