    Ongoing reliability of Kalkhoff/Focus Impulse 2 motors

    I'd like to know what fails in the motors and how the failures have been resolved? At the moment I'm under the impression it is the freewheel/hub in the motors that breaks, and it has been resolved by making the motor soft start and with lower power? I'm sure a comprehensive answer to that...

    Ongoing reliability of Kalkhoff/Focus Impulse 2 motors

    Except the Karoo doesn't have a 20ah battery. Seriously I think the 15ah battery would be flat at around the 30 mile mark if I rode it around here. Sorry about the extra h woosh

    Change Bosch Classic motor

    I guess there must be a few configurations they can be set to, wheel size and whether they are for a bike with a derailleur or hub gears, the later having a softer start and less power. Have you a link to the supplier please? I'm tempted to buy a spare motor.

    I used to, although I only ever borrowed them for a few hours, these days I often don't even bother looking and just list as e-bike now. KOM's on the flat take some beating on a hybrid.

    Ah I see what you mean now, It must be a long commute, Whoosh would say you can go 120 miles or so on 20ah.

    Help us build a better Ebike battery

    If only that were true, I'd have to be extremely economical with the assist power on my bike to achieve 70 miles from 500 wh, it's more in the region of 30 miles or less for me.
