The data appears to indicate that a zero cost, yet effective design of a turbo boost is to start out riding in MTB Upright, and when you want the turbo boost you shift to MTB Tuck :thumb: . On top of the extra speed you get the added bonus of more range
.
Pedal assist is greatly effective at starting speeds, important when you want to beat cars when the light turns green. Even on my 675w 20mph "geared" eBike, often it'll take cars half a block to catch up. Though, click shift might be needed as I shift through 5 speeds in 5 seconds.
While 250w of sustained pedal assist will give you an additional 3mph, to 30mph ...
(800w output motor of above's motor simulation)
The same 250w pedal assist will increase your acceleration:
643% (46w to 296w @ 1mph)
352% (99w to 349w @ 2mph)
276% (145w to 395w @ 3mph)
229% (193w to 443w @ 4mph)
202% (243w to 493w @ 5mph)
186% (291w to 541w @ 6mph)
175% (332w to 582w @ 7mph)
165% (385w to 635w @ 8mph)
157% (435w to 685w @ 9mph)
152% (480w to 730w @ 10mph)
...
134% (728w to 978w @ 20mph)
"Turbo" might be most easily applied via standing start, transitioning to crouching on lowered seat as 20mph threshold is passed.
Please note, also.
Pedal assist can be especially effective as eBike slows on uphill grade!
