Hey Freddie! Thats pretty darn good efficiency! How much do you + trike weigh?
1) Efficiency, 8.5-10 Wh/Km
2) Speed, 35 kph cruise, max about 42 kph with pedaling.
3) Gradient, up to 10% for my commute.
4) Pedaling, moderate.
5) Homebuilt tadpole trike
6) bafang rear brushless, geared. 20" wheel.
7) ??? Std, 36v, 14.8 A
Ping LiFePo4, 36v/10AHr
I haven't weighed the trike in quite a while, and it has gone through some mods!
Original weight was 22Kg, add 3 Kg+ for the Bafang motor, and 3.5 Kg for the Ping battery. Maybe a 2-3 kg in rack/panniers guards? I weigh less than 75 Kg, so I'm guessing 110-120 kg all up? I am running narrow high pressure front tyres, and a similar tyre on the back. I think that helps.
I also think the lowish Amp rate of the controller helps a lot too!
With my riding style, I tend to avoid adding power from a standing start, and I pedal whenever I can, especially going uphill! There are even times, like on a downhill run, or slow speeds in traffic, when I don't even engage the power.
Hmm, maybe I should weigh her again? Dunno, but I'm actually thinking about a new, lighter frame. My new trike is 16.5 Kg bare, but that one was built for a different purpose, i.e. group/rando rides.
