Very new to the wheel I think I only got the hang of riding on friday, the wobbles were so scary at first they happened when breaking and accelerating down hill, and when accelerating past a certain point period. Recently I've found that they're strongly related to my not doing duck feet or having my feet very far forward on the wheel, or not having it so that one foot is further forward than the other. Gripping the wheel with my calves/knees a certain way seems to have an effect. As well as how far forward I put my calves to grip on the wheel. A quick correction of this or my feet, while in movement after slowing sufficiently, however terrifying always seems to fix the problem.
Now I'm getting the please decelerate warning, any suggestions on what levels to keep your speed alarm and tiltback for a more heavy (250) Rider on a 16s? I think I keep tilt back at 32kph my 3rd alarm is at 30 to let me know if I'm pushing to hard.
