"high-speed-motor" means the internal speed of the motor. The higher internal speed follows a higher rpm-reduction in the planetary gearbox. the SWXK or SWXH or SWXB work with 4,3 rpm reduction and the BPM with 4,9 rpm reduction. That´s what "high-speed-motor" means. now the real high speed...

I agree with flecc that the hall-sensor replacement is´nt an easy job, i would not do it. If a sensor is failed , I would use an sensorless controller and forget the hall-sensor´s ;) I like easy solution. You know how to measure the sensors ? regards frank

Hi tetpol, on the left side, diskbrake side is a a 28mm/12mm bearing if i remember right. but your idea dont work. I had a look on your picture´s and i belief to know what you want do but i see no chance to do it this way. it is more easy to design/modify your knee-cruiser new. If i...

if you use different controller, you receive different noise and vibration on e-bike Motor´s. Good controller produce low motor-noise and some ... forget it. it depend on different quality´s at the controller and what is inside the controller and the programming of the controller in...

i agree in all points with flecc and i belief for the most people a v-brake is enough. Cheap and high-effective. But i ride my bike in mountain area and myself is 115kg, i know i´m to fat:) so i need diskbrake because in mountain area and my weight the rim-side´s is very fast distroyed...

Near by, but sorry, my english is to poor to explain this problem. a short try, the programming on sensorless motor/controller is not so easy and the signal is not so clean as on sensor-motor/controller because it works with "against EMK" i dont know whether it is correct written? And...

Hello John, there are different Bafang SWXK Motor in trade. SWXK Sensorless and SWXK with Sensor is on the market. Also Version one and two is on the market. The version two is much more easy to fix a diskbrake too as on version one If you have a Bafang SWXK with Hallsensor, you can use...

Hi, in all Hub-motor with freewheel, bafang, xing-feng, tongxin and so on is a clutch inside otherwise you wouldnt have a freewheel ;) usualy the clutch never go brocken. For Bafang, a clutch with rigth turn-stop and in left turn stop is possible, in case you have the diskbrake on right side...

Hi John, first you must check witch sort of sensor you have some give a pulse signal and some give DC-signal. Also you must check the DC signal of your controller for the PAS, 99% it is 5V but a few controller have higher voltage. then you must find a dealer for the PAS, this should be no...

hi john, i have seen a lot of different PAS but this is a stupid construction of a PAS. Only solution, buy an other one. regards frank

If there is relly an intrest, you must know i have an Importservice so every order i place in China at the Producer and it need around 3-4weeks before you would receive the stuff. i have made an example to make clear the cost, 8Motor is minimum order: 4x BPM Motor different rpm is possible...

hi, you can fix the sensor on both side of the crank, any sensor is able to work on both sides, you only must turn the sensor. today i´m to stupid to upload an image, i dont know why so I make a special "help-point" on my website, please check Elektrofahrrad, pedelec zubehör scroll...

dealing with Ping-Yueh Lin from Cyclone works well. Only paypal is possible but it is very fast, usually after one week the stuff arrive in my home, if they have in stock. I agree with flecc, I also dont like this chinese tradition of changing the names to give the western people a feeling...

What you want to know? My experience after testride is: Driving in flat terrain give good support up to more than 30km/h and bring a lot of fun. Controll of the speed is a little poor, on a very small fingerwheel as a throttle. You need Kojak tyre´s otherwise it is to noisy. Or you use the...

the 250watt version had not this heat-problems this motor works well and the plantary is stabil but the noise is the same. I had driven this motor by 36v with crazyman controller and pedal-assist because i dont like the throttle-grip, it makes my hand tired. with 36v the motr runs much...

hi, you can also order the pedal and speedlimiter set on cyclone, it is no so expencive. Then the throttle works only when pedal, if you stop pedal the throttle/motor also stop working. In this way the set fullfill european law I had setup an sensorless crazyman controller to the...
