Item specifics

New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is ... Read moreabout the condition is proud to present the worlds most powerful bicycle hub motor 6kw true wattage guarantee! Uk stock don't be fooled by cheap imitations No for the faint hearted
We are official uk resellers of this hub
Cromotor V3
- Continuous power : 6000W
- Weight : 11kg
- Stator manufactured from aluminium,
- Additional silicon steel and copper compare to previous versions​, providing better heat dissipation,
- Higher efficiency on low speeds and higher speed
- Better cooling at higher speeds.
- 11 awg phase wire
- Dual hall sensors 120 degree
- 10k temp probe in windings wires brought out
The minimum recommended rear swing arm dropouts is 155 mm. Very good mechanical skills are needed for this motor to be mounted on 140 mm dropouts. It’s possible, but strongly NOT recommended and you might not be able to fit a disc brake.
This version has a different stator. The old version was a stamped steel stator and these now use a cast aluminum stator. The stator lamination’s are made with a high quality silicon steel and also have a little more copper fill. This all translates into a more efficient cooler running motor.

Electrical Specs:
Continuous power handling: 6000W (please read the following note about wattage ratings), if you stall the motor at zero RPM and put 4000W into it of course you will melt it, even 1000W could would damage it if left stalled for long enough. Your wheel size plays a large factor in this, the larger the wheel the less efficient the motor, on flat surfaces this is generally a non issue, but if you choose to climb steep hills with a 29″ wheel using this motor I suggest you carefully monitor the motor temp and also the controller temperature. Another note about using large wheel/tire diameters is to watch your power. This motor produces very large amounts of torque and a 28-30″ diameter tire is a very long lever. This can produce a lot of stress on the axle. If you intend to build what amounts to more of a motorcycle or moped than a bicycle I suggest you run a tire with a diameter no larger than 22″ to keep mechanical and electrical stresses within reason.
The same general rules that apply to all hub motors still apply to this one and must be observed. This motor is capable of surviving many situations where other motors would not, but caution must still be used.

kV measured 9.5kV (9.5 RPM per 1 volt)
Inductance 145uH
Hall sensors are spaced at 120 degrees,double set of hall sensors 2nd redundant set
Phase wires are 11 AWG

Motor comes as seen is brand new and tested unlaced to a rim. We can lace to rim for additional charge
Manufacturer's recommendations :
Controller to be set up to max 80A with 72V, or higher voltage with lower Amp.

Manufacturer's additional info :
120 kg driver should be able to go up to 45mph max speed, for maximum 60 minutes, in the hotest summer going uphill
At 72 V and 50 A motor will last forever, and max speed will be just under 42mph.
This motor has been designed to be reliable for many years commuting at higher speeds that average electric bicycle, and with lot of torque for uphill, any users using it for breaking speed records, should do so at their own risk.

The axle ends are 40mm long from the shoulder and have 40mm of thread 10mm flats. This means that the V3 Axle is 40mm+155mm+40mm for a total of 235mm long with the 155mm shoulder to shoulder portion centered along with the flange. Axle threads are 16×1.5mm thread pitch if you need to buy nuts other than the ones supplied.

Like almost every rear hub motor, you may run into caliper clearance issues. People have fit many different types of calipers, some which are very wide by using a 203mm rear disc. This larger disc allows calipers to stick up high enough to not rub on anything but due to variances in frame design you still might have a tight fit.

Freewheel choices are fairly limited due to the width of this motor. Most people choose to run a single 16 tooth freewheel. (Not included)

This is the most powerful three phase brushless direct current (BLDC) motor available for use in a bicycle frame without the need for extensive modifications. It was adapted from a light motorcycle / scooter hub design to allow those who want a really powerful motor to finally get one. This motor is all about torque and when you feed it the amps, it really comes alive. It will produce scary amounts of torque if you feed it lots of volts and amps, so you will need very strong drop outs and most likely torque arms if you plan to install this motor into a normal bicycle frame. Please keep in mind that this motor is rated at 6KW. That’s a lot of power and some of the speed freaks are regularly exceeding this in short bursts, but it’s pushing the motor beyond it’s design specs. This motor is capable of propelling you to very high speeds if you choose to do this, but you must be careful and know what you are doing or you may hurt yourself, the motor or your bike. A police officer might not be too pleased to see a bicycle flying by him at 60mph either. With that said high speed should be done on private property as it’s illegal to ride an electric bicycle fast in most places (check your local laws). This motor was brought to market mainly for commuters who want something that can tackle any hill they have to climb during their commute. Responsibility of how you use this motor falls on you, the end user.

Here are some simulations that greyborgusa run to let you estimate the speed and current required to maintain it in relation to the voltage of your battery pack at different tire diameters. You may use this chart to help you decide on a battery pack configuration and controller.

Simulation was done with Bicycle + rider weight at a total of 275lbs. All diameters are tire diameter.

Warranty :
All motors have been carefully tested by the manufacturer and by us at wimbikes, and in the unlikely event one of the motor would turn out to be faulty, the motor will be replaced.we can only give full warranty on motors that are compiled with our surrounding components.
Please note, it is the user's responsibility to ensure this motor is used properly, with the right settings, the correct controller and adequate battery packs. Motors will not be replaced or serviced if neglected or abused. 6kw is 6kw voltage x amps = watts (1000w to a KW) if you exceed this temp should be monitored closely. Motors are tested with supplied wires and can handle 6kw constantly without issue. If running higher power levels warranty will be void if damage occurs due to over heating the hub but we are always here to help with build / repair or modification. For further support ask support team at we always here to help
