    All this knowledge.

    Sigh.... I think to a certain extent we(I) should take the blame for that as we mollycoddle our kids too much. Only yesterday my teacher daughter (she marries and moves out in August) got in on her bike and said "dad the gear changer is broken". I dutifully take it to the workshop and fix it for...

    BEBA Survey

    It does not really cover DIY bikes which a lot of us here do, but I am guessing we are in the minority anyway. I filled it out as best I could using generic responses. Regards Jerry

    Kit fitting problem

    I am curious, why not ? Does the motor shaft only have flats on the non threaded part ? Regards Jerry

    £20 Ebike Battery

    Thanks John, I have only been in this game just over two years and to give credit where it is due everything I have learnt has come from this and other ebike forums. I have made some great contacts on here from which I have learnt almost everything, the most enjoyable being wheel building :)...

    New Kudos Secret bike

    From experience just buying the odd part from China is hard enough. Trying to buy in bulk with all the language barriers and different business etiquettes must be a nightmare! I can see the need why you would have to go to China and meet your business partners before parting with cash for large...

    Another Minimalist EMoulton Build

    To be pedantic the Moulton does not fold, it splits. As always its a compromise. The Brompton folds small and conveniently, the Moulton rides like a dream :p That is not a torque arm its known as a leading link which is part of the suspension. As this is only a 180W motor and the front...

    Brompton electrification

    Cwah, If you don't put the chain tensioner back on you won't be able to wing the rear triangle under without the chain falling off. Also I think the chain tensioner is required to ensure the rear suspension can operate correctly (the triangle moves up and down when riding) again without...

    Yes Scotty its probably as close as I can get to no electric fit. As you say the real advantage is to help with take offs and cope with the few inclines (railway bridge) that we have in Cambridge. I doubt the battery would suit many UK landscapes but fine for Cambridge. There is a fitting on...

    Brompton electrification

    Easy to add or remove links. You are also going to have to drill out the tensioner fixing hole as it will be too small for the larger motor shaft. PS and it is made to go over the smaller nut that attached to the original back wheel shaft (see above pic). The new motor nut will be larger. As...

    Brompton electrification

    My Moulton gets a lot of attention to keep it looking nice. The Brompton is my work horse, though I even try to wash it down every few weeks. For me half the fun of bikes/ebikes it the constant fettling :o Regards Jerry

    Brompton electrification

    cwah where is the Brompton chain tensioner ? You need it to take up the slack and stop the chain falling off when you fold it. Also you are going to have to check your chain line. Regards Jerry

    Thanks for the comments. They are 30c constant and 60c peak. All in my battery build thread. The controller only pulls 12 amps max anyway. Regards Jerry

    Another Minimalist EMoulton Build

    You may notice this new build has a radial built front wheel. I have done a couple now after advice from Alan/catsnapper (many thanks to him). They look wonderful even if they do have limited application. I have also managed to get some decent spacers. These are machined out of plastic...

    Another Minimalist EMoulton Build

    Been meaning to post some pictures of my re-working of my EMoulton TSR2 What you are looking at above is the completed bike ready to go with battery. Weight 14.5kgs. It uses the latest small controller I got recently with my Tongxins and my new £20 battery all in the bag. The battery 36v...

    Brompton electrification

    Moulton's make great conversions with front and rear suspension. With lots of advice from Alan (Catsnapper) I have also recently built two radial wheels myself including this one for my latest minimalist Moulton build. I will start another thread. I have been taking lessons Regards Jerry
