@d8veh you have patience of a Saint, we should really name you St d8ve.

For a three wire speed switch (aka throttle) one needs to connect the wires in the correct sequence so show us what you have. Typically a thumb speed switch is Red /Blk & White, Red & Blk will mate to the same colours on the controllers connector and the White to the Blue. White & Blue are...

Hub motors for hill climbing /inclines are much dependent on the motor winding /rpm of the hub. A faster wound hub is not as efficient as a slowe rwound hub. To be able to comment on your hub one woul dneed to know the rpm winding and the current /voltage used.

OK worth a try with the tape some times. Let us know how the new disc works out as we like a successful conclusion to a simple issue.

The magnet disc needs to be approx. 1mm gap to the sensor head so if your disc is warped then yes one will see operation issues. Often the magnet disc is held in place on the bottom bracket axle by small plastic splines incorporated in the disc. Check the disc is firm on the BB axle , that it...

Gear changing has changed a lot since my first drop bike in the 70's with gear changers on the down tube . Now we have nice all in one brake lever gear changes with with an inward side swipe of the brake lever to go up and an inward side swipe of the smaller inner paddle to go down the gears.

Still have a BPM laced in to a front rim in the garage hanging up, certainly lives up to it's acronym of being a Big Powerful Motor. They are in the main sensorless.

Road bikes have caliper different hole spacing to MTB/hybrid bikes.

One assumes the exsisting controller uses solid state type electronics so a shunt mod is out of the question ( though is possible). Suggested scenario is to upgrade to a KT system for about £80, the KT programming allows a wider power range on PAS from 13% - 100% in five stages of power.

A fad bike for seaside dwellers, have to say the girl was fit . Advertising seems to like to employ fit birds to sell stuff no matter how useless the product may seem.

Hailong and Polly cases look similar , the Polly though looks to be the closer option when you look at the bat1 jpg pic.

The three melted bullet connectors are a common sight and are the phase wires , they simply can't handle strong current. They either need to be soldered directly or one should use a MT60 tri connector. The white wire disconnected is a speed restriction wire . Green/Black are brake sensors ...

Looks like a DP-4C Polly battery to me , one can see them at topbikekit.com.

Sadly efforts at pointing out these illegal riders ends up with them becoming unruly and offensive , it seems age has no barrier . Also sadly trying to reason with someone like that is akin to trying to polish a turd and a complete waste of time. You did your best Andy only to receive a...

I should think that bike is pretty awful to pedal hence the speed device , however set up as it is it doesn't comply with EAPC regs so is currently a moped and thta means it is a motor vehicle. The gig on so called throttles which are just speed devices because there is no throttle variation ...

With KT one has to enter the P & C parameteres to change a setting , one can have PAS only , PAS and speed device set or pedal first option before speed device is activated also one can have a password so no one else can enter the settings. As long as a speed device can't actuate above 6km/4mph...

Only the speed control device makes it illegal unless one can change settings to make it a pedal first option.

There is a low voltage EU directive for DC powered tools etc,etc , with I think approx.70v being the max for hand held /usage items. However EAPC's weren't included in tha list and the max DC voltage for said bikes was set at nominal 48v.

You will have to select from the drop down box a LCD display , your exsisting display won't communicate with the KT so one will get error code and a non working bike. The motor connector is good but as has been said one may need to change a Hall or phase wire sequence so if possible one will...

The country will need a name change soon , it is becoming the The United Hates of America. Trumo 2 , to go down as the worst presidency in history ?
