I have answered that question in a PM to you
Here is the copy. In case I'm wrong in any aspect, please correct me.
The
Peak Power setting is the one that primarily responds for the Vado's acceleration while the
Support is about how much it should help you during the ride in general.
Let us assume your legs are strong and you only need to compensate for the bike's weight and general resistances in the Eco mode for the ride. You might have set the Support to 25%. The Peak Power means how much power is delivered to the motor when you step on your pedals harder. It might for example be 100% Peak Power. There are three situations in which you might need high Peak Power:
- Cold start, e.g. from signals at the junction;
- Riding uphill, for example negotiating an overpass;
- Overtaking someone.
The Peak Power overrides the Support when the cyclist stamps on the pedals hard. Let us assume you're in the Eco mode and will just ride up the overpass. With high Peak Power you don't need to switch to the Turbo mode; you'll be just pedalling harder, the motor will temporarily get a lot of juice and you'll ride up without even losing the speed. Of course, that will make the battery used harder and will reduce the range.
In the simplest words: The more Peak Power in given Mode, the more "sporty" and less sluggish the Vado becomes.
Other interesting settings:
Acceleration Response determines how fast the motor will respond to the rider's pedalling. With 100% (city ride, dry good surface), the motor will respond almost instantly when you start pedalling, like in a racing car when you press the gas pedal. With 0%, the motor will kick in with a good delay. The latter situation is for riding in wet, muddy, snowy, icy, slippery conditions. You would not like it if the rear wheel got high power in a fraction of second and started slipping under hard conditions. 0% makes the motor kick in after the Vado has started really moving. Setting of 50% is in my opinion the safest.
Shuttle mode. Let's assume you feel the most relaxed when you pedal slowly. Now, you are being hit by a gusty upwind; the bike slows down. My reaction is to downshift and pedal faster. With 100% Shuttle Mode, the motor gives more support when you are pedalling fast. With 0%, pedalling faster or slower takes no effect on the assistance level.
Hope that helps.
