    Fitting an internal dropper seatpost

    im planning to fit an internal dropper to my cube stereo Ebike but hate unsightly cables. Is it a simple job to access the inside of the frame tubes round the motor? Is it a simple job to just take the cover off the motor or does it need dropped out? Thanks

    I managed to pick up a second hand one on gumtree with charger for good money so that saved a lot of hassle. Good old gumtree.

    Bosch powerpack replacement

    I asked that too, it was a colleague moved to the uk from Germany and the bike made it safely but the battery and charger got lost in transit. He could stomach the £800 insurance payout for replacements on a bike that would end up being worth £1200 at best so I gave him the £400 and he bought a...

    Bosch powerpack replacement

    To answer part of my own question I have identified the 37v +Vé and -Vé contacts and the computer powers up. It says the battery is empty so won’t power the motor. I now need to find out which of the other 3 contacts send a signal to the brain and what that signal is.

    Bosch powerpack replacement

    I previously fitted a cyclotricity 1000w to my bike and made a battery using hobby king quadcopter batteries. All very successful. I have now purchased a bike with no battery or charger and wonder if I could build a 36v replacement using hobby kings again. The original battery was Bosch...

    Cyclotricity 1000w kit and a specialized hard rock

    I have a low voltage alarm on them that goes off when it hits the trigger value. I think ( need to check my note and the setting programmed in) they charge to 14.4 v using the balance charger and the low voltage is set to 11.8

    Cyclotricity 1000w kit and a specialized hard rock

    I'm new to all this, When you say BMS is that to do with a balance charger? I remove the lipo' s and charge then individually on a balance charger. If not that, can you give me more info? I charge them outside in a non combustible area as I have read some scary stories. Thanks

    Cyclotricity 1000w kit and a specialized hard rock

    I test drove my new project. A £40 specialized hard rock sport and a 1000w cyclotricity. 24mph on the flat , me pedalling but with the very high gearing on the bike. Haven't got the derestriction code yet . Is the code unique for each unit or is it simply a hidden menu. I have also made a 5ah...
