I’ve had a Kalkhoff Include for two years now. It’s been reliable and fairly maintenance free. The original tyres were too skinny so I upgraded them to 1.75”. (Has anyone managed to fit 2”?) The ride is a bit jarring and the seat post spring seems to be set for far heavier people than me (143Lb). This a subjective opinion but I think the Impulse EVO motor firmware is biased in favour of long range rather than heft. So far total mileage is 2500. I’ve some issues about the Kalkhoff Include’s ability in wet weather but so far no problems - despite going through a ford or two. Typical bike ride for me would be about 40 miles. I’m located in Wokingham in the UK.
