* Disc Brake Upgrade:

Your bike comes with a set of single Shimano ZEE disc brakes. You can upgrade disc brakes by choosing one of the options below:

  • UPGRADE SINGLE BRAKES: upgrade both, front & rear disc brakes from (single) Shimano ZEE (standard) to (single) Shimano SAINT disc brakes.
  • UPGRADE TO DOUBLE (FRONT) BRAKES: upgrade from single front Shimano ZEE (standard) to double front Shimano SAINT and single rear Shimano SAINT disc brakes.

* Footing Options:

Read more on how to choose the right FOOTING OPTION in the tabs below.

* Front Brake Lever Position:

Qulbix bikes typically come with a front brake lever on the right side of the handlebar, which is a motorcycle arrangement. This has proven to be the most practical option, since the regeneration brake lever is on the left side of the handlebar. But, if you wish you can opt for an alternate position and have the front left brake lever positioned on the left side (classic bicycle arrangement).

Other Add-ons:

Choose to add a KICK-STAND, a rear and/or a front MUDGUARD.

* Seat Options:

Read more on SEAT types: moto seat and bicycle seat.

* Tires:

Please select at least one tire type. Read more on rear 19'' moto TIRE types: MX, Intermediate and Road tires. The front (26'' bicycle) tire type will match the chosen rear tire type.

Feel like having a nice, long ride around the county or a quick run up to the woods? Just change your bike's seat type (from moto to bicycle style seat or back), your bike's footing (from pedals to foot pegs or back) and tires (choose among MX, intermediate or road) and your bike is transformed to suit your needs best!


Qulbix performance e-bikes are no pretty little city dwellers. They pack enough power to get you up that hill. Regen brake on your way down, and you can do an extra round before hitting home.

You can customize your Q140R in any way you want, all parts are modular, and can easily be replaced.

3 options in 1 e-bike:

Q140MD Options


This is the Q140R basic version. Perfect for riders who want to take full advantage of optimal seat height for best pedalling performance. 


This option combines the best of both worlds – pedalling to get a workout out of your rides, and larger sitting area to precisely position your body weight when cornering.


Have no intention of pedalling when your monster e-bike can put out 15kW? No problem, this version is rid of everything your e-motocross bike can spare: pedals, chain ... No extra junk, no fuss.

STRONG & RELIABLE - Doing It Right

Be sure, quality matters when you’re riding off-road.

As fancy plastic and carbon frame casings will crack on contact, Q140R’s steel and aluminium frame can take a beating, and still work like a charm. Q140R is no pretty little city dweller, it’s an off-road monster waiting to be unleashed!

Quality Matters!


Q140R’s frame is made of extra strong steel (tensile strength: 1200N/mm2) and 7075 aluminium.


Our bikes are designed and fabricated in Europe, they're quality made, TIG welded masterpieces made of super strong construction steel, and we guarantee they will hold.


The Q140R frame is not only strong but also built smart. Its shell like frame design can store large battery packs and ensures that it will stay well protected even if you fall.
