    Fiido D2 conversion to KT controller upgrade not working (noisy motor and cuts out after 5 seconds)

    Hi all, Not sure if anyone can help, but i've been pulling my hair out over a problem with a controller upgrade on my Fiido D2 and wondered if anyone had any pointers or ideas as to what i can try next to get it to work ? The old controller on the bike is a WK3615YS 2019.08 36V 120degree...

    Blown my controller BBS02 750w :(

    Damn it !!, it would seem that i have blown the transistors in the controller on my Bafang BBS02 750w after a good few years of daily use, I have always run it on a 14s turnigy multistar 8ah battery, replaced 2 cells in a battery last year after they started to puff up, but other than that, its...

    My rear derailleur just snapped off !

    I've spent my budget now ! and repaired my bike Bought some Rockshoxx Bomber triple clamp forks with 20mm axle, and new wheels front and rear, downhill specific ones that are massively overbuilt, double width rims and really thick spokes and beefy hubs. Also bought a better spec rear duaralier...

    Hub gears for my bike

    #sigh# your not making a good case for me to buy a rohloff !!, in my excitement 2 years ago, i forgot to set the min max range screws thinking i'll give it a ride, let it settle in, then adjust it, but forgot, that was untill it went into the wheel when i shouted 'oh dear' (or words to that...

    Hub gears for my bike

    Your right of course, i forgot that !, but it was the cable snapping as i changed gear that caused all this damage and the changer ended up in the wheel, possibly as it tried to change 9 gears instantly, the chain got caught up and the gearset then used the chain to wrench the changer off the...

    Hub gears for my bike

    Im already using a wipperman chain !, very good chains. It wasnt the chain failing that caused all the damage, it was the gear cable snapping inside the sheath, the gear changing has been a bit sticky and difficult for a few weeks, and i just push through it thinking i must sort that out, but...

    Hub gears for my bike

    I commute to work from Kilminton to Lyme Regis, and the hills are steep and long, some of the steepest in the country, we constantly get complaints from the holiday makers about how steep the hills are ! Also, I tow a trailer with my bike and take an electric chainsaw up to the local forest to...

    Hub gears for my bike

    I'm stll thinking Rohloff though, hoping that can handle more, but realise that i am pushing too many watts for any of them to handle reliably, so now wondering if i am wasting money buying one if its not going to be up to the job and break ? Too many options now, and a wife approved budget to...

    My rear derailleur just snapped off !

    Just off on my dog walk (or dog bike) and about 2 miles into the walk my bike grinds to a halt with a horrible grinding clattering noise, I was doing about 25mph off road at the time and quickly stopped then looked down to find my rear derailleur was resting inside my back wheel !!! Its done...

    Turnigy Graphene.

    Ahh, so not just discharge rate improvements then, my multistars can charge at up to 2c, but i struggle to find a charger that can better a 1c charge anyway, a 14s pack of 16ah multistar batteries charging at 1s needs a 940w power supply, so to charge it at 5c would need a 4.7kw charger ...

    Turnigy Graphene.

    Very nice, it might be time soon for me to get a new set of batteries as my tunigy multistars seems to be dying slowly 1 cell at a time, I've lost 2 cells in the last month that have dropped to 0v suddenly although the overall capacity of the pack remains pretty much the same as it was 2 years...

    Battery box/bag needed

    Lol !, its only one of those mini lathes from Axminster power tools based on the Sieg C2A but it came with the dro kit and all the optional extras you can buy for it for milling so was a bargain !

    Battery box/bag needed

    Thats a pain !, it looked like a neat and tidy solution but i dont want to wreck my frame, I bought myself a lathe just before christmas which has milling capabilities, so this might be the ideal problem for me to tackle with it !

    Battery box/bag needed

    Thanks for the offer, but i have already bought a rear rack that bolts onto just the seatpost, and i'm currently crafting (bodging!!) a waterproof lunchbox with all the batteries and the bms board and packing it all tightly so it doesnt move, then its going into a shoe bag that will then get...

    Building a battery pack for the Cambridge University Eco Racing Team

    Nicely built battery, lots of attention to detail in that build ! But, I thought solar powered race vehicles were solely powered by the panel ?, if they are allowed a battery pack, surely the panel is just for show and its actually just an electric vehicle ?

    Battery box/bag needed

    Now that looks very interesting, hadnt thought of mounting it on the unsprung part of the rear triangle, my batteries weigh in at 4.4kg , do you think it can handle that sort of weight ? Its not quite the stealthy/streamlined look i was hoping for, but it looks like a very sensible solution
