i think this is an admirable effort. however, i don't think it can be used for straightforward comparisons between gear, as bike configuration (including handlebar/seat height! and tire choice), rider weight, terrain, number of stops/starts, presence of a headwind or tailwind, pace, and riding style/pedaling effort play a HUGE role. i could use 0 Wh/mile with my current setup and have used as much as 37 Wh/mile, after all.
that said, here are my data:1. Efficiency
. 25.89 Wh/mi lifetime average as of today. Scatter plot of energy use over time.2. Speed
. I cruise on the flat at 22-25 mph but my CA-reported average is almost always 15-17 mph due to hills as well as many stoplights and stop signs along my route.3. Gradient (%)
. My normal route has 250 feet of vertical gain over 1.22 miles
: an average grade of 3.88%. There's a short pitch in there that's probably a 5-6% grade.4. Pedaling effort
. Moderate. My bike is geared such that I can pedal along at a reasonable cadence whether going 5 mph or 30 mph.5. Bike Type
. Flat-bar hybrid with 26x1.75" semislick tires, with handlebars about level with the seat
.6. Motor Model
. Crystalyte 407 in a 26" wheel.7. Controller Model
. Crystalyte 72V 20A pedal-first controller.8. Battery
. 48V 12Ah prismatic ebikes.ca LiFePO4.
