* 9) Color Options - Frame Stickers:

See all the standard sticker colors HERE and all fluorescent colors HERE.

Bike Add-ons:

The standard rear chain wheel size mounted on a Q140MD Core e-bike is the 30T chain wheel for the optimum speed / torque ratio. You can check the box(es) below to add additional chain wheel sizes to your order. The standard Core comes with a twist grip throttle, but you can choose to add pedal assist system. You can also add mudguards and/or a kick-stand to your bike.

* Color Options - Frame Kit:
* 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).

* Grips Upgrade:

You can choose to upgrade the standard grips to a softer set of rubber OURY MX grips. See the comparison HERE.

Customization options for the Q140MD Core performance electric bike:


The Q140MD Core was the winning e-bike in the first ever FIM E-XBIKE World Cup race (read an article on the MXGP website or go to MXGP Mag magazine) in Imola, Italy in 2019. Since then it has become our best selling performance e-bike, and now we've decided to make it even better.

2020 Q140MD Core bikes will feature a brand new throttle activation type: PAS (Pedal Assist System) option. Beside the classic moto twist grip throttle you will now be able to opt for a pedal activated throttle as well. Read more below.

The New Q140MD Core 2020 The New Q140MD Core 2020 Handlebar

The New Q140MD Core 2020                        -               The New Q140MD Core 2020 Handlebar


The new pedal assist system lets you add throttle by simply pushing on pedals. You can manage the starting power of the first few pedal pushes with the PASS ASSISTANCE LEVEL SELECTOR and tone the over-all power of the bike by choosing one of three power modes, using the POWER MODE SELECTOR.

The new PAS option will enable your e-bike to have three throttle set-ups:

  1. Classic moto style twist grip throttle - use only the twist grip to regulate throttle.
  2. Twist grip throttle AND pedal assist - use the pedals or the twist grip to regulate throttle. Using the twist grip will override the pedal assist throttle. This double throttle option is best for off-road trips, where you wish to have a workout, but also want to have maximum control over throttle in case the terrain gets to rough for pedals.
  3. Pedal assist - use only pedals to control throttle.

Throttle set-ups can be easily be regulated on your bike's display. You can also set up an end speed lock, at 25km/h.

Now you can transform your Q140MD to mach your needs. Ride it in four different ways - from an off-road explorer to a pedelec with limited speed of 25km/h.

This means your Q140MD Core can now be ridden in 4 DIFFERENT WAYS:

 Ride it like a/an:





 Throttle control

 By pedals (active PAS 1) only  By pedals and twist grip 2  By twist grip only  By twist grip only

 Footing type

 Pedals  Pedals  Foot pegs  Pedals 

 Seat style 

 Classic bicycle seat  Classic bicycle seat  Moto style seat  Moto style seat


 Can be restricted to street- legal 25 km/h  Full  Full  Full


 Commuting, getting a classic bicycle work-out
 Off-road trips, exploring nature  Training of MX tracks  Challenging off-road terrain, such as steep hills and on narrow forest paths

 1 Pushing the pedals will activate the pedal assist system (PAS); twisting the grip throttle will over-ride pedal assist and activate twist grip throttle. Using classic disc brakes or regenerative brake will cut off both types of throttle.

 2 The bike can be started by pedals or twist grip throttle. Using twist grip throttle will over-ride and shut down pedal assist. Using classic disc brakes or regenerative brake will shut down pedal assist for safety reasons.

One bike. In 4 different ways.



Uphill tracks, wheelies, power slides – don't let the gravity stop you! Qulbix e-bike's massive power will satisfy even the most power thirsty riders. Qulbix bikes provide enough power and torque to get you places, and fast! 



Rugged, uneven terrain, that’s where your performance electric bike will shine. Have the time of your life and get the workout you need. All with one powerful, quiet, cool looking machine.


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.

STRONG & RELIABLE - Doing It Right

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

As plastic and carbon frame casings will crack on contact, Q140MD’s steel and aluminium frame can take a beating, and still work like a charm. Q140MD is no pretty little city dweller, it’s an off-road monster waiting to be unleashed!

Quality Matters!


Q140MD’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 Q140MD 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.
