The PAS is dual Hall. Best get in touch with Andy, email support@wooshbikes.co.uk . He will help you solve it.

You can. You won't feel much drag from the motor.

Did you get the tsdz8 or tsdz2b?

Hall sensors: Andy or me replace them ourselves. Speak with Andy, he may have a solution.

The connectors only fit one way: battery > extension > motor. Excess cable goes inside the bag. Ask Andy to send you some pictures.

You have two wires: red to red, black to black. Ask Andy to send you a picture if you are not sure. Did you download the installation manual from the webpage?

It behaves as expected, so expect 250rpm. I am still getting to know the new kit. There is no manual yet.

Yes. It's the size of a 6 fet controller

The new Tongsheng hub kit arrived last week. I have been using it on my bike. The kit comprises of a 1.8kg motor, a stem mounted LCD, a controller in standard aluminium casing and two cables: one goes to the LCD and the other to the motor. stem mounted colour LCD: Here it is mounted onto a...

Braking on a 100kgs bike + rider travelling at 25kph does not generate much power. The kinetic energy of 100kgs at 7m/s (25kph) = 2450J = 0.68WH. Some of it will be shed by the rotor, brake pads and the motor, the net recovered energy is even less if you only want to slow down instead of...

We usually need to know who the first owner is, pictures of the bike, details about the faults etc. in order to assist you. Your situation is a tricky one. On top of that, you did not post any pictures of your bike and the state of the bottom bracket. I don't know if you have the tools and can...

magnet discs don't cost much, it's usually the post and packing that costs more than the goods. The main thing is we can help you better when we know your situation exactly. The Big Bear was sold for nearly 10 years. When we get your email, we can check your email address in our database to find...

Your picture shows a replacement pedal assist magnet disc, we use this part in some kits. We have the part but it is not what was fitted originally to your big bear. This is why I suggest you contact us. We have various models, the cost is about the same.

Please email support@wooshbikes.co.uk we will help you.

if the BMS talks to the charger then fast charging at 10A is very doable.

what happens if you smoke your battery while fast charging it at 10A?

EV's batteries have different chemistry compared to most of e-bibke batteries. The latest Lithium iron Phosphate from CATL (they called it the Shengshin battery) can be charged at 4C until 100% full. Your e-bike battery would normally be charged between 0.2C and 0.4C. When you charge a battery...

I watched recently a YT video about some thermo-electric engines. The idea is simple enough: you burn fuel to heat up some salt like table salt in a jet engine. The sodium in the salt emits an intense yellow light. At the closed end of the chamber, you place a photo-electric cell whose band gap...

Cheap Chinese bikes rust. Chain, pedals, seatpost, bolts and nuts, brakes cables and brakes. Also, most of us are overweight. We need some suspension and hydraulic brakes.

unfortunately, most of the important progress is only for cars and trucks' batteries: rapid cost reduction, durability, fast charging, standardised connectivity and energy density. e-bike batteries are left in a mixed bag with tool batteries. Just look at how little you'd pay for a car that can...
