The Fiido D2 has fairly weedy looking front forks, so want to stick with rear hub drive really, but I'll have a look for a Q128c or a G370, but it has to be a 36v motor capable of a 20a peak current

I havent been able to identify the make of motor, but the hub motor has this written on it 16" 36v250W19H7789 FIIDO 4

Its still available !, nice, but i forgot that they are 48v and my bike only has space for a 36v battery unless i rebuild, but its quite a small battery space onboard, so best to stick with a 36v motor i think.

Thankyou Guerney, Some interesting finds on Ebay there. Back in the day (when i started Ebiking with a BBS02 750w!) that was about 7 or 8 years ago now, there was a Bafang BPM rear motor that seemed to be the best you could get for hills if you wanted a hub motor, but have they disappeared ? or...

I've just spotted that Woosh sell hub motors, and some really nice ones too, but only as kits with everything including the battery and controller sadly, Its a pity that there aren't any UK hub motor suppliers. I think if i cant find anything by the weekend in the UK, then i'll do the alibaba...

Id say the noise was like the old milk floats of many years ago when they pulled off, they made a sort of groaning noise, and my bike is sounding the same.

No, the cable is in good condition and protected but a metal spring type thing covering it.

Thinking about my current motor a bit more, I do wonder if its actually faulty as, although it has a 5 wire hall sensor connector along with the phase wires, It does make quite a noise when riding under power even with the original controller, loud enough to make people look round as i'm...

Hi, Yes, I tried all 36 combinations (took ages!!) and 3 of them produced usable results, but all 3, in real world testing had less torque and were quite a bit noisier than the original controller the bike came with, so i am back on the original controller at the moment, and i just have to get...

Hi, Its definitely a D2 without gears, I wanted the lightest bike i could find, so figured it would be lighter without all the gears and changers and stuff, but maybe i should have got the D2s! The trouble is that i broke my leg in 3 places a couple of years ago, and its never fully recovered...

I put the 500w in brackets because i thought it might be an issue, but i've read that some 250w rear hub motors are ok with being driven with a 500w controller ? and i believe (but might be wrong again!) that its the motor rating that decides whether its legal, not the controller rating ? Any...

Hi All I'm looking for a 36v (500w?) rear cassette hub motor to go with my new Kt 10A (20A peak) controller on my Fiido D2 folding bike, but am struggling to find anyone in the UK that sells them ! Its got 16" wheels and i'm happy to lace it up myself, and am looking for decent hill climbing...

Back again for an update. The bike is riding ok now, but it has less torque for hill climbing than on the old controller, but does seem to have a little bit more top speed on the flat. I dont think its voltage sag or the bms holding the power back as i'm drawing a solid 19.7 amps going uphill...

Back again, I've been out for a test ride now, and its running nicely, slightly nosier than the old controller, but it doesn't have a much torque for climbing hills, less than i had previously, and on measuring the current under load (very tricky!) its maxxing out at 19.5 amps but seems less...

Right, back again, got called away for shopping duties with my wife !, but now its dark i wont be doing the test ride until tomorrow, One thing i have just found is that my back hydraulic brake was binding and making the wheel stiff to turn, I don't think the caliper liked being upside down for...

You're absolutely correct !!, I just found the third smooth running configuration (typically, it was the 36th test!), and they all draw exactly the same current and sound as smooth as each other, so i'm guessing it doesn't matter which of the 3 i use now then ?

Is there a display that shows watts whilst you are riding then ?, I did want the KT LCD9 but couldnt find anyone with them in stock in the UK and i ordered from TorqueTech in the end but they only had to LCD05 in stock

I will plug the pedal sensor back in then and see what its like, I guess i can always programe it to off even with it plugged in, I guess i was going the lazy route by simply not plugging it in ! And I will give the P1 settings a try, thanks, but i'm not worried if it doesn't work, I guess i...

Good news !!! Its running really nicely, and sooo quietly too, much faster than any of the wiring configurations tested so far, should i just accept this one and use it ? or do you think i should test all 36 combinations to see if there's an even better one ? The good working one was the 8th...

That makes sense, I know its got 20 magnets in it for the drive, and we are starting to get a little bit beyond my knowledge here !, but are there a different set of magnets used for the speed (hall?) sensor then ?
