Very nice and clear explanation.
Vado SL is not the "heavy" Vado, so I cannot make any advice. Let me show you how that works with my 1.2s motor equipped "power Vado" and my poor legs:
The 1.2s motor offers maximum motor power of 520 W if your cadence is over 80 rpm. My legs can provide constant 100 W when I'm fresh, 150 W when I really need it, and 80 W when I'm tired.
100% of Max Motor Power is 520 W. Maximum rider leg's amplification with that motor is 320% (3.2 times).
Here are my custom modes developed for use on long trips with a spare 604 Wh battery in the pannier:
Long Ride, Two Battery Setup Scenario
- Steroid Eco: 40/50. On constant pedalling, the motor power is: leg power * 3.2 (320%) * 0.4 (40%) = leg power * 1.28. When I constantly provide 100 W, the motor power would be 100 * 1.28 = 128 W. However, the motor power ceiling is at 50%, that is 520 W * 0.5 = 260 W. If I provide 150 W by hard pedal treading, the motor will provide 192 W, which is within the power limit.
- Super Sport: 50/70. The amplification factor is 3.2 * 0.5 = 1.6. With 100 W rider's input, the motor will yield 160 W. With 150 W input, the motor produces 150 * 1.6 = 240 W. which is still inside the limit of 520 * 0.7 = 364 W.
- Full Turbo: 100/100. The amplification factor is 3.2. Provide 100 W yourself and the motor will help you with 320 W of power. Provide 150 W and you'll get 480 W of support, still within the 520 W max motor power.
I can only tell you riding in the Steroid Eco on the flat guarantees me the range of 80.2 km (50 mi) sharp with the 604 Wh battery, good roads, mild wind, Summer conditions, few stops.
Short, Fast Ride (Tired Legs) Scenario:
- Power Eco: 50/70. Amplification factor of 1.6, maximum motor power 364 W. 80 W leg input, 128 W of assistance. In case 150 W can be provided by the rider, the max motor assistance will be 240 W for the short effort burst.
- Power Sport: 70/100. Amplification factor of 2.24. Maximum motor power of 520 W. 80 W leg input will yield 179 W from the motor, a 150 W burst will result in 336 W of assistance.
- Full Turbo: 100/100. Amplification factor of 3.2, max motor power of 520 W. Tired 80 W legs will be assisted with 256 W of motor. The 150 W burst will yield 480 W, still within the 520 W ceiling.
- Now, many people sport stronger legs than mine. If @Nubnub provides 200 W of power and rides in Full Turbo mode, the motor should give him 640 W of power but it cannot do it, so 520 W will be provided by the motor max
- The latest 1.3 motor also maxes out at 520 W but the max amplification factor is 3.6. It favours weaker riders. Strong riders are advised to significantly decrease the assistance levels with Mission Control for far better range and only necessary pedalling assistance.
- The 1.1 SL motor has max power of 240 W, and the amplification factor is 2.0 or less. SL bikes are for fit people with strong legs.
