What is your Miles per Amp Hour used?

I did a 60 mile ride and this is what I saw on my Cycle Analyst. I have nothing to compare it to so I thought I would ask. My bike has a gas motor as well and it was also running at the time these stats were made.

Amp Hours used before Regen: 8.8 Ah
Brake Regen Amp Hours placed back in the battery: 1.99 Ah
Actual Amp Hours used for 60 miles: 6.8 Ah
Total Regen of batteries capacity: 29.1%
Max. Speed: 38.2 MPH
Avg. Speed: 22.5 MPH
Max. Amps: 42.3

Miles per Amp Hour used: 8.82
 
I wonder what your true bottom line results would be with the gas motor off since the gas motor creates drag (transmission, chain, tensioner etc)

Actually the gas engine was solely propelling the bike down the road about 80% of the time. That's why my results are so off the charts high. LOL

The batteries would be dead within about 30 miles without the gas engine.

I get ~ 2 miles / AH.

Yep, I get just a bit more than that without my gas engine running and I paid over $700 for my 48V 13 Ah battery. That totally sucks.

So I more almost quadrupled my range with gas engine running and Brake Regen activated and it's still not enough for me and my range is about to fall off a cliff when I install my 26 x 4.8" tires.

Mine gets a half mile per amp hour of battery, but it also has 8 hp and can pass cars uphill, lol.

Now that's what I'm talkin' about!! LOL

I'm tossing out my 49cc 4 stroke for a 98cc Lifan that has the same physical dimensions. I initially tried to squeeze a 9HP 200cc go kart racing engine in my bike but it just wouldn't fit. Ended up selling it for a loss.
 
My chain drive currie ezip, modified with a 40ah 24v LiFEpo4 pack.
First let me say, Pittsburgh is HILLY!
Cruise on bikepath full throttle 190lb rider and some gear 10A/16-17mph.
(in theory that's 4hrs X 16-17mph = 64-68Miles range)
Based on recharge times I can count on 1Ah/mile, ie a solid 40mi range inc hills.
I pedal about 15-20% btw.
Alloy frame, 250w hub motor Lithium Manganese 10ah bike (54lbs vs 70, 85psi vs 65psi)
I have run it 19mi and LVC was cutting it off. So about 0.51Ah/mile.

I'm getting about 8 miles per Ah as long as the 49cc gas engine is running. Terrain here varies but not the stoplights. There's millions of them and it seems like I hit every one of them.
 
Miles per amp hour should not include GAS... Or even pedal.. IMO
A real test would be on an indoor velodrome track, WOT etc...
Do you know that the record for fuel economy is something like 5,000mpg?

True it should not. I'm just trying to gauge the improvement gas/electric makes over a pure electric bike. I would go all electric but my Lithium Nickel Manganese Cobalt batteries cost a small fortune.

5,000 MPG. I could live with that #.
 
It would seem to me a nice small gas friction drive on a hub motor wheel might do pretty well to increase the mpah.

On a trike it has to go on the front wheel and that is the only good breaking wheel so it is difficult at the very least.

If I went lith it would be for the weight since I don't travel long distances but I would miss all that reconfiguration of the battery packs.
 
it's called a SOLEX , 1950s/60s tech and they SUCKED ASS.
low speed and ate tires left and right.. EWWW!
 
The tires is true there was also the honey bee the bike bug and several other including some new one being built now. The poor performance really is dependent on the size engine and tension on the tires.

Up side lift it off the tire and there 0 drag.
 
It might be easier to compare Watt hours per mile as some have 24V or 36V or 48V. I read somewhere that with active peddling you can figure it takes 21 watt hours/mile. That seems to be what I'm getting using a 36V 450W geared front hub on a Sun recumbent trike with active peddling. The 12Ahr lead acid battery get me about 20 miles. 12Ahrx36V=432 watt hrs/20 miles=21.6watts per mile. This is on packed gravel roads with some moderate hills using 2 inch tires at 42 psi. and I'm not moving real fast, probably 10mph average.
