    Smile Begining of an e-Brompton DIY project

    I've just received the battery from China. Again, I do not want to cross-post so here is the link to the Pedelec forum:

    Here's some interesting GPS tracking data:

    http://www.pedelecs.co.uk/forum/elec...html#post61464

    The electric motor assistance shuts-down somewhere between 20-25 km/h, and furthermore I only use it for going uphill (the Brompton was really heavy thanks to a decent shopping load)

    I'd estimate that on the steepest hills I only contribute 60% of human effort. The rest of the time I am probably providing between 70% and 80% of the effort required (anything below the 20-25 km/h speed
    curve).

    At any rate, I have now learnt how to properly use the pedelec mode (choice of gearing, etc. due to speed-only sensor, no torque sensing), and I am beginning to enjoy it !

    Cheers, Dan
