You can't get with this bike on one long hill or riding at full speed some time it will overheat. I try with second gear option (max. 70 km/h) on MX track and bike stoped on half of it. It is so heavy compared tofor example Sunron.,
If I am honest this bike is useless with pedals because they are so short and bad gearing ratio. This bike have pedals are there just that it looks like a bike
Hi Guys,
Before we introduce the new, Q140MD Core 2021, we'd like to comment on some old post, which were left unanswered.
REGARDING THE OVERHEATING of some of the 2018/19 versions of Core - there was an issue with the sensor calibration, which was related to the controller. The temperature reading on some bikes was incorrect - the actual temperature of the motor was much lower than it was detected by the sensor, and the result was that the bike shut down to cool off, even if it didn't need to.
When we discovered what the issue was, we notified the affected customers and offered the instructions how to re-calibrate the sensor and fix this problem.
A few words about the motor:
The Core's motor is a quality BLDC outrunner motor and is additionally cooled with fins on the outside and ferrofluid on the inside. The low rotational speed makes practically no noise (compared to high noise motors from other manufacturers like Sur Ron etc.), has a lot of torque and allows us to directly connect it with the pedals which is a unique solution on the market. No other manufacturer offers mid drive bike with this kind of pedalling feature.
REGARDING THE Q140MD CORE'S PERFORMANCE
Since 2019 we have been involved in racing and Qulbix has become a part of the FIM e-bike race format development committee. We have tested the Core in the harsh conditions of the race and have incorporated these findings into to newest version of Core. You can watch the latest race of the FIM Italian national championship in cross e-bikes in Italy here:

From this video you can get the feel for the Q140MD Core's:
- clear power/performance advantage
- there are no overheating issues in 1 x 10min training, 15min qualifications and 2 x 15min races, which push the bike to its limits
- the Core's sound - it is quieter than other offroad bikes, such as Surron
- the use of pedals - they are optimised for hard riding, so you can corner and jump without issues. They work up to end speed and enable the rider to get the maximum work out from their ride. Of course their purpose is not solo propulsion of the bike, which has so much power it does not need human assistance.
- our bikes are the same weight as Surron
