3553 - wow I wonder what sort of wind that is, even the 3540 is a 12x5.
So are they claiming 53km/hr on 36v ?? Sounds a bit excessive. I wouldn't advise people get that wind for offroad riding, I imagine it'd have VERY soggy performance through most of the speed range you'd actually want to ride it.
I think the 3540 would be the pick of the bunch on 48v. The 25 is too slow unless you're running 60v+ (in which case it's great) and the higher speed winds will lack torque unless you throw masses of current at them, in which case they'll get hot.
What current limit are you running on yours remf ? I imagine with 3548 it feels well down on torque compared to the bomber ?

There's also a 3543 in between the 3540 and 3548 !!!
In terms of torque, yes the Bomber pushes way more, much faster climbing hills and much faster acceleration. Can't recall the current limit and I'm nowhere near the bike, could be 65A. So yes in terms of all round performance, I'd have to agree, the high torque winds are preferable and the 3540 may be the best of all.

I failed to mention one of the other caveats to my decision is that I am planning (after a year or 2) to get a LiPo pack built so I can swap it in when I want a bit more power etc.
I was hoping to just be able to wack the LiPo pack in and instantly get more volts/amps ect and not have to modify/replace the controller in anyway. Is this realistic?
Based on this (and what you helpful people have already said), I would think I should go with the 3548 motor. What do you think?
Cheers,

I don't know if there are any motor options. I didn't get to choose. I can imagine the issues with everyone wanting different this, different that. Cost would be more, lead times would be longer etc. No harm in asking though.
Great thing about Stealths, there's nothing stoping you from installing your own LiPo whatever either with the stock controller, a new controller or a different wind motor.

I do not think it is so much about the speed but more the environment drawing the amps. At high speed I do not draw that much power unless I am climbing hills or riding in soft sand. I would be able to cover over 30 miles at high full speed but I expect it could be as much as 40 to 50 if all on road.
If you weigh more and cycle lots of hills in to the wind and you had the knobbly tyres then it would be a lot less than the hookworms with a light rider on the flat.
40-50 miles is a long way. Don't forget that you can recharge in about 2 hours.

With my Bomber...
I have gone 66 miles and still had more in the battery and think I could have gone 70 total.
Amps were set to 7 max (575 watts) as I was riding with road bikes.
Riding at WOT 99% of the time to test the battery capacity I have used as much as 65 WH/Mile but that is far from normal. Normal to fast would be maybe 30-40 WH's/Mile.
Bomber battery should be 1500 WH's but I only show 1400 from new so you can do the math EZ to see mileage.

I don't know, 51 miles @ 35 mph sounds high but yes this is for a 156 lb rider on 0% flat terrain so it may not be too far off the mark. I've only been able to go on one long ride so far, just over 25 miles but with lots of stop starts & WOT on steep grades.

WOW! T'riffic vid mate. Love the variety of camera angles and Melbourne...the most liveable city in the world according to the Economist Intelligence Unit's Global Liveability Survey of 140 cities...also undoubtedly one of the best in the world for bike trails 8)

I dont understand what that 52 miles ( you circled in Red) represents. First, I tried the calculation on the ebike website (thanks) but it doesn't appear to ask for the capacity of the battery, how can it determine range if the battery capacity is not defined. I also input all the data you provided in the chart you posted and I did not get 52, I got a number like 27? whatever that means??
Am I missing something here ? what is 52, at first I assumed it was a calculated theoretical range ?

The battery selection drop down menu is there...I selected the 20 Ah Ping at 52V.
You can then click in the graph to select a different speed at 100% throttle at various % grades whatever you like OR reduce the Throttle selector bar and see the effects of reduced throttle, especially on range and Wh/mi, quite interesting.
So if you set all the options, yes theoretical range on flat ground at 100% throttle (WOT) is 51 miles. Real world, probably something less than that.

30 miles would be a safe conservative estimate at 25 to 30mph.

The graph Kepler posted is correct - look for the black and red curves to cross each other. That's where the motor's output equates to the wind resistance. The graph remf posted is for rolling down a hill.

I was wondering who would pick up on that. I should have known :? -5% downhill coast and you'll get 51 miles. Still interesting to have a play with the numbers...my Fighter will do 35 mph easily but for how long??? That will remain a mystery for now.

A battery's capacity (Gas Tank Size) is listed in watt hours (WH)
1100R is 875 WH's I think
Fighter is 1200 WH's
If both are driven at the same speed there is no question the Fighter will go further on a charge.
The fighter will go faster as well and 0 to 40 MPH far faster so it would be possible to drain the battery quicker as one can pull 1100 watts and the other 3000 watts if demanded.
One is quiet, faster, better range and costs less.
One is noise, slower, less range, and cost more.
BTW I have had both an Optibike 850R and a Stealth.

Some nice angles to see the suspension movement at speed.
Been enjoying your Contour camera?
Good points Paul
The stealth fighter does have the higher capacity, until you add the aux battery to the 1100r. The problem is the aux battery raises the center of gravity. I want to be able to get at least 30 miles out of whatever bike I get, at higher speed, with some hills. I like how the fighter has easier acces to elec for maintenance too, but I'm not sure if it has the range at the speed I desire. So I'm asking for various rider experience. I contacted stealth but they are sticking to their advertised specs, which seem low, and understanly conservative. The bomber is a bit too heavy for me.
