    Your Creation's Before & After Pics

    Out of interest would adding an annalogger be the way to look at all the signals to diagnose the issue. I find mine varies the output when pedalling at a constant speed and effort. You can be going along at 300W and then suddenly up to 900W and then back again and i cant quite diagnose what...

    Your Creation's Before & After Pics

    Nice one. I found that having access to the higher gears was not necessary on my build once you have power assisting you. https://endless-sphere.com/forums/viewtopic.php?f=6&t=100917. In fact i lost the front gear selector and only use the bigger chainring. So the bottom bracket issue might...

    Grin Brompton Kit

    After looking at all of the options available here in the UK and stumbling across this forum, it was clear that the Grin solution was the one for me. Primarily because they are so open about what goes into their products and provide all the test information. If you look at other kits available...

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    I have a Crystalyte H3525 UFO and a heatsink set. Noting that Grin talk about installing thermal pads to make up the diameter so the heatsink fits, does anyone have a recommendation for the spec of the pads? Thanks Tc

    Seeking motor and controller advice on 1-1.5kw folding bike build

    If you still have problems I can recommend the SAW20 that comes with the brompton kit that they do. I have only 30 miles on mine but it is very impressive. 25mph no problem apart from shaking everything else on the bike off.... Trevor

I am about to try to convert my specialized stumpjumper and will do a careful measure before ordering. Likewise battery position will...
