    BBS HD internal friction

    I have used my BBS HD for about 300 km and i output power is more and more reduced.
    I have never used more than step 7 out of 9 steps -using about 750w.
    But the bike is slowly getting "slower".
    No sound.
    Yesterday my girlfriend with av BBS 02 750 watt on reduced power was "parking" me and then I realized that there is a problem with the BBS HD.
    The BBS HS was also comsuming a lot of energy emtying the 17,5 Ah Ah battery.
    Leaving me emty after 20 km when the BBS 02 had a lot of power left.

    Any suggestions?

      Using 2 batteries. An last time my girlfriend used one of them. I have never hold my hand on the motor other than last time. But i did not think it was hot. When motor was new it was possible to get aprox 50 km/t. Not possible now. And very nice the comparement with my girlfiends bike - BBS 02 750 watt at reduced power just rushed away while I on step 7 of nine (aprox 750 w). Same bike, different motors.
