The power (Watts) is less (PAS = Pedal Assist Sensor) Full charge 36v battery and typical 15 Amp controller = 630 Watts Empty battery = about 480 Watts Motor speed will also be reduced because it = RPM per Volt X number of Volts In the real world that means I used to recharge as soon as the...

Does it turn the motor off? If so it is working.

Anything I buy from China is VAT and duty free if the price is under 100€. The other solution is to buy from a company that has an EU warehouse like PSWpower, VAT is included (theoretically) in the price. Note that Bafang is setting up a factory in Poland so in the near future Bafang products...

Don't forget to factor in 10-20% less Ah than on the label: - salesmen are sometimes overly optimistic :rolleyes: - over time the total capacity will diminish to about 80% of rated capacity so it is better to buy a larger battery than you think you need

What kind of coffee machine? How many kWh? How many hours will it be running? Once you have those numbers you will be able to calculate the size of your battery pack. You want a 48v motor and your batteries would be 2 x 24v used in series for the motor and in parallel for the 240v AC inverser...

Yesterday was very productive! Lots of loose ends were tidied up: PAS I started out with PAS in the normal position as shown below The cable was extended to about 2.5 metres long and attached to the gear outers all the way back to the controller. The disk is zip tied to the 26 tooth...

I had my Number Two up in the workshop last week to replace chain and gears and gave it a quick wipe with a soft cloth. It did get a quick bucket wash last year at about the same time. I do wipe the trike down with a rag a bit more often just so that it looks pretty :D

Unfortunately Julet and Higo connectors are made in China and that is where you will find the lowest prices and the cheapest shipping (often "free"). I doubt very much that any European electronic parts shop stock such items which are only used where water resistant electrical connexions are needed.

Decathlon seem to prefer the absolute shortest bottom brackets for some reason. Dremel is your friend! I put a disk on the left hand side and to make it work I cut the centre of the disk out and mounted it to an adaptor cut from the bottom of a coffee can - more or less 4,500 km later there is...

You might get away with 4 links, I just lengthened a chain to fit my 46:11-42 up from an 11-34 cassette and used 8 links and it is a bit sloppy. 7 links would have been perfect... Yes the 11-50 would be my first choice for a 1 X 9 setup. The cassettes aren't quite up to Sunrace quality but...

What size cassette do you have? Correct gearing is more than just a chainwheel. I have gone back to the stock 46 tooth on the GSM because I have a new 11-42 cassette, the motor would stall if I had an 11-32 cassette (real life experience).

1. They are plug and play. 2. Your motor needs headlight wiring output for the headlight control to work. You should have an unused plug coming out of the controller.

If the 38 is listed as being for a triple it will have the holes. Other 38s will be the external ring of a 2x setup.

First road test and I really like the compactness - some would say stealth but I'm not hiding anything. I can't see the average speed, do I have to ride for more than 9 km for that to display? Mine is on it's side for the moment but even upright there is no way I can see the screen while...

It all comes down to the quality of the bearings in the hubs. If you have a mid drive bike with wheels built around DT Swiss ceramic bearing hubs then there will be less rolling resistance than cheap Chinese ball bearings in a hub motor.

Here the lad rides one with a 750W Bafang BBS02 marked (badly) 250W. He is set up as a proper business and insured and top speed is limited to 25 kph, I pass him under pedal power alone. I think 25 kph is the sweet spot for little old lady passengers... He charges 2€ per km with a 2€ fee per...

I'm bent and electric! First test ride with the KT-LCD4 and the new non Bluetooth controller, the setup went smoothly but the LCD4 isn't for blokes with big fingers! Pressing the up and down arrow buttons simultaneously is a bit fiddly even for me. There is a typo in the online manual - passing...

Somewhere in the French postal strike there may be an eight speed shifter/brake lever combo, the nice Chinese man first sent me a 7 speed one by mistake... As soon as it gets here there will be two bikes in bits in the living room: - Alivio 8 speed rear derailleur off the trike (replaced by...

I think the first reason is mostly cost. A 10S4P battery is cheaper than a 13S4P battery because there are 12 fewer cells and at the price point of most hub motor bikes on the market that makes a very big difference. Second reason is weight - a 48v BPM is quite a bit heavier than a smaller rear...

Both. The charger detects that the SOC of the battery has reached 42v and turns the LED to green and stops sending current. If the battery drains to 41.xxv it will resume charging. The BMS starts balancing the cell groups when the SOC reaches 41.5v and when the first parallel group reaches...
