you can try https://www.greenbikekit.com/ http://www.pswpower.com/ven.php? They ship more cheaply from Germany. Look for BBS01B + 13AH battery. If money is tight, try XF08C rear hub kit + 13AH battery http://www.pswpower.com/ven.php?cargo.2020-35-brmt

what is fairly constant is the maximum power delivered by the motor. The torque is equal to power (in Watts) divided by the angular speed (in radians). The faster the wheel turns, the lower the torque. If your bike has a crank motor, the power is entirely transmitted to the rear wheel by the...

I can, but you would have to pay VAT on importing from the UK. Your budget is not enough for the whole kit, even with Chinese battery cells. Take a look at local suppliers first, as most suppliers on Aliexpress don't ship to Turkey. You need to budget at least £400-£500 for the kit and taxes.

If you want a hub motor, choose a geared hub. If the vendor lists gear reduction ratio: higher ratio is better. If the vendor lists dimensions: larger motor is better. Post the link to what you intend to buy here, we'll check for you. If you want a crank drive motor: choose Bafang BBS01B - it...

No. You need the LCD. Press and hold both the Up and Down buttons for 3 seconds to enter setting mode (long press). Press up or down button to scroll through the settings until you see max speed. press M to select. press up or down to change the setting to 25km/h Press and hold the M (mode)...

yes, that's correct. The OP started already with a kit that is not road legal.

yes. If you want a motor to be best at going up x% gradient at y kph, then just get one that is optimally built for that purpose. When you move one of the parameters, like applying a higher or lower voltage, you lose that optimal yield. That means the motor will shed more heat, become noisier...

to climb a mountain, you'll need plenty of torque which is the power that turns your motor wheel. As with most things in life, it's a trade off. For the same amount of power, if you want more torque, you trade speed for torque. It means in practice you need a crank motor so you can change gears...

have you got an LCD on your bike? if you do, the maximum assisted speed is set in the LCD. Just tell us which LCD it is.

give it two weeks.

That is why I suggest fitting a BB (bottom bracket) with the correct axle length and diameter. make sure that there is 1mm air gap between the crank and the left side sensor and the cranks rotate freely after installation. The problem with kits sold on amazon and ebay is they don't come with...

I beg to differ. The left side PAS is much easier to install and replace. You need a BB axle of 122mm if your BB shell is 68mm, 127mm if your BB shell is 73mm. Check also the diameter of the BB axle, it should be 16mm. If yours has 17mm dia axle, replace it. If it's too short, replace the BB...

I am listening Sunak's speech in the HoC at the moment. He impresses me.

if I understand correctly, the corona virus that spreads is a mild form, it does not kill its hosts. When it invades a new host, depending on the genetic makeup of the new host, it goes through a mutation. This is when about 2% may die from the mutated virus. we still have a window of 2-4 years...

it's difficult to see when this crisis will be over. The NHS tested about 30,000 people, found about 1% of those tested with the virus. That could mean that as much as 1% of the population can be spreaders. The real long term problem for people in our age group is re-infection. You can get...

I equate wearing a face mask to doing a short range self isolation. Our Chinese suppliers sent us a stash of face masks a couple of days ago. The masks are sealed in plastic bags but the bags are wrapped in local newspapers. Hatti treated the wrapping like nuclear waste.

I am taking all the precautions: open the shop to the public only on appointments, prepare for all essential staff to work in isolation, one room per person, wear disposable daily face masks when meeting in the same room, keep windows open for extra ventilation. The idea is the virus particles...

I'll ask my builder to sort it out.

brexit? it's put back on the shelf for now.

You need enough motor torque to suit your weight and how hilly is the area where you live. If you weigh around 13st, I suggest 42NM should be plenty, 15st 45NM, 17st+ 50NM+. Higher torque usually means also heavier and larger motor. The FX2 is a lightweight bike, so the additional weight of the...
