I have both an Alice and Nesta and have had the opportunity to test the for the first time today.
Both have been run in on a rolling road for the recommended 30 -45 minutes and a bit more , however, both are slow to start or need a nudge when they do at slow to medium speed they both 'pulsate' or jerky along the track (like there isn't sufficient enough power to turn the flywheel) turning up the power up they run quite smoothly but too fast!
I'm using a cheapo Hornby controller, before I return them could controller be the issue or is further running in required or return them?
It just seems strange they both react the same way at the slower speed but ok at a higher non-realistic speed
