Must admit I haven't fitted the throttle, am I missing out ? I was struggling to think when I'd use it
Here's a few:
1. When your pedalling is hampered by something you're carrying in one hand or a big shopping bag over your shoulder, you can use the throttle to get you started.
2. When you have to stop on a steep hill, it's much easier to get going again with a throttle
3. To give an instant over-ride whatever power setting you have on the LCD, especially if you're daft enough to set it with the maximum number of levels. That's useful on roundabouts; to get a burst of speed to beat traffic lights; to get a burst of speed when you need to escape from potential danger; to save a lot of button pressing, when you get a short steep hill. like hump-back bridge; when you overtake a roadie and shout, "get a motor" at them and they start chasing you.
4. When you fall off your bike and it hurts too much to pedal.
5. When your knee suddenly goes towards the end of a very long ride.
6. When your pedal spindle snaps.
7. When you forgot to fully tighten your pedal on your new installation, and the pedal comes loose and knackers the thread so that you can't put it back in again.
8. When your left hand crank comes loose and starts making that clonking noise.
