this greasing issue is quite annoying for a potential customer, i've had different brands of chinese hub motor in past years and never i had to service any motor with additive grease, if the grease quality is unsuitable or no special wrench is provided by Xda for easy opening up the 2 speed...

i met Mr Ching and his son in Eurobike in Germany on the 7th of september and he told me of the upcoming challenge ( because i dared to mention other e-bikes were more powerfull that his own ! specially a XU 700 canadian bike that - in my modest opinion - outperformed eZee models by its power...

Tks so much Flecc...it's most informative so i suppose here again ( like with the eZee torq ) the BMS is separated into 2 control boards , 1 for the the first bank alignment of 5 cells , and the 2nd one for the last 2 cells ...as in underneath photos

after opening a BMS , these are the main elements in photo that i can peer ... is that questionning you ? this BMS is attached to a Lithium manganese battery pack made of 7 cells of 8Ah capacity each ( 24v 8Ah battery pack )

the sales man informs me that the freewheel mechanism is 100% efficient because intead of being made of ballbearing clutch like on Bafang ( ? ) it's made of an overrunclutch that makes the driveshaft of the motor to be totally disengaged from the bicycle wheel's shaft if the motor is not ON or...

because the yearly consumption of e-bike is 30 millions in China when at the same time it's 5 to 10 000 in England or France

any opinion about that bristish ad ? Cycling Awareness Safety Video from Transport for London | Virginia Bicycling Federation

in sincerity i believe there is a dominant standard in the chinese e bike industry, fast-in fast-on automotive connectors for Hall & motor leads and/or Bullet connectors, and for 90% of the apparatus to be connected to the controller ( brakes, pedal sensors, power throttle , power displays ...)...

tks for both above advices , but i want to keep the original type of connector so that in the future if i try new motors or PAS or controllers i use what seems to be the ordinary chinese mini connector standard ...it has the quality of being very small and that's vevy convenient if the available...

In order to modify the PAS ( Pedal Assist Sensor ) I’m using with my controller , I need to modify the connector end on the side of the PAS ( see photo ) , which mean cut , undo , re use , switch in , etc…with lots of care and patience …. The final result is a failure as seen on photo…so now...

to confirm Flecc's saying about Hall sensor to be responsible for noisy phenomena, i was told that motor factories are controlling the quality of the Hall position sensor they use , and discard the bad ones that are to be held responsible for excess noise 2 photos fm the Bafang factory to...

from the basic hypothesis that a life span expectation of an e-bike hub motor is directly correlated with that of its orbital planetary gears ( especially when made of Nylon like the Bafang motors ) or bearings ( Tongxing motors ) i am interested in knowing if there is a way to measure such...

thanks Flecc for the accuracy of your description from the attached link but i believe the freewheel mechanism comes into action in that chinese hub motor in a different way than with the Bafang you described, so since i have not tried that motor and the photos are being sent to me by a...

many among the members of that forum complain that their motor has too much drag in case they are coasting or if they simply power off their motor and wish to use their e-bike as a plain bicycle I here have attached some inside views from a Chinese hub motor – supposedly geared and brushless...

Cyclone DIY kits on fire different techical drawbacks have been reported from end users about that Cyclone company in Taiwan on the french pedelec forum Cyclurba , including some fire accident in France by explosion of Lithium batteries sold through Cyclone Taiwan Co., i would strongly advise...

did you try to remove the throttle , thus starting the motor only from the PAS ( Pedal Assitant Sensor ) ?

nobody's home at Tongxin as soon there is a problem Brett White in Australia ( solarbbq@hotmail.com ) has experimented the Tongxin motor and reported of many problems in regard with the controller ,i think he knows quite a lot about the Tongxin controllers , you might ask him since Diana Lin...

tks Jeremy, but i'm afraid the new motor axle is in different dimensions than the typical hum motor axle ( in photo ) do you yourself own a Tongxin hub motor ( the new model without the 5 hall lead wires , a version probably appreared mid or end of 2007 ) because their new drawings does...

torque arm or special washer to avoid damages whatever is the limited amount of nominal power of that small hub motor , it's probably capable of withstanding instantaneous power of 500 to 700 watt for a few seconts ...( the controller enables 36v x 15 Amp H ) under such circumstances a...

axle dimensions of Tongxin and standard fork dropout slot spacing ?? hub motor axles are generally flatened down to 10mm on 2 opposite edges ( see attached photo ) , because standard dropout slots are also 10 mm wide , so that the hub motor axle can easily slide into place . unfornutanely...
