P1. Is setting based on the internal gear ratio x motor winding magnets used, with a correct figure and P2 set correctly it gives a ear enough odo reading. P2. Is wheel speed pulse or magnets sensed per revolution. P3. Speed control or current control for PAS use. P4. How the throttle works...

The ten pole PAS is the best option. All items selected from the drop down boxes will be a match so plug and play. The drop down boxes are there to make it almost fool proof.

D/D hubs are a plenty they are on ebay etc,etc and are heavier 5kg + hubs usually black and large in diameter, most are 1kw or more.

As vfr mentions the gearing isn't changeable, the exception is the Xiongda 2 spd hub that does it automatically. The gearing is a simplistic clutch with tri planetary gears running against a larger sungear machines on the main hub casing, the clutch simply allows freewheeling. Unlike a D/D hub...

These kits are not CANbus like Bosch, Shimano or Yamaha etc,etc, any generic battery can be used. The only part that is semi Canbus (if use wish t call it that) is controller/display which need the same matching programming protocols supplied via the tx/rx lines. All or most digital comms are...

Geared hub motors have an internal clutch so when one rides with no power it will still happily freewheel. When/if trying to turn the wheel acw then yes you will feel some whirring resistance as the clutch doesn't freewheel, what you hear are the central planetary gears being turned by the...

A geared hub should quite happily freewheel as a non motor wheel does.

All my KT controllers are torque simulation as that is what the Chinese like to call current control, they only need the 1/4 turn to activate. These are std off the shelf ones sold by many vendors, a lot of 12 pole magnets are used with KT controllers. When CANbus is mentioned is full hands on...

If you wanted a different display then yes one would also need to change the controller an option if the controller ever fails, topbikekit sell the integrated KT controller.

It doesn't say that on my pc, the user monika applied is by a computer a litho gramme and reacts to how many posts one makes.

If the integrated battery controller is a Lishui then no you can't, KT aren't compatible with Lishui.

One has to enter the settings in the display and see what the P2 value is. Turn the display on depress the +/- buttons simultaneously for about 5 - 10 secs, the basic settings will display, quickly press the on/off button going thru the first sequence of basic flashing settings. When the last...

Nice for readers or potential buyers to know the difference when looking at two bikes that in all but name look the same, they have choice. The UK built one also has the local/UK back up should something go wrong.

Most likely issue is that one of the phase mosfets has fried, rather then use one of those stupid light gadgets it will be much easier to understand with proper resistance values by using a Digital volt meter. Simply disconnect the controller (no power) , attach the probes to Red battery input...

BBS models/power rating. BBS01 36V 250/350 or 500w . BBS01ETM 36v 250w uprated internals and 25a controller. BBS02 48V 500 or 750w. BBSHD or some call it the 03 model 1000w. Plenty of sellers about.

30Q are high draw cordless cells that some have used for bike batteries, they have shown to be ok for bike batteries but for most uses are not worth the extra cost to use and as vfr say's are overkill 120a discharge for a 15 - 20a max current take. One could as vfr says use cheaper 8 -10a rated...

The new kits use a slower wound hub motor, I believe they are now higher torque 201rpm wound rather then the previous 280/300 rpm wound hubs. At 36v 28 -32kmh is about the top assisted speed so about 17 - 19mph. Some LCD's have adjustment to 70km/h but this doesn't mean drive's can attain this...

For generic battery operated bikes that don't use handshaking between components then any battery of the correct voltage will work or one can opt for a re-cell from the likes of eikebatteries.co.uk who provide top service. Other bikes with handshaking you are at the mercy of genuine battery...

As vfr say's lift the geared hub wheel off the ground, a hub rear hub motor or a front one will quite happily free wheel many rotations as a normal wheel would. It matters not whether powered or not the hub wheel should freewheel if it doesn't then either brakes or rubbing is hindering rotation...

My C300 has three connectors and not the same. It was used with a hall sensor Lishui controller A throttle 3 pin Julet, male pins. A 2 pin brake . A 8 pin trunk cable julet, male connector (yours has female connector) this is different from your 8 pin connection as it doesn't have the 8th...
