Agreed - the Crossfire-E puts out over 400w as standard - this is confirmed in the Suntour Documentation that comes with the bike. Also confirmed by comparing hill climbing performance with my Kudos Tornado @15amps.

Let's just get one thing straight in case there's any confusion. Releasing the speed limit doesn't change the power in any way. The motor will almost certainly make less power above 15 mph, so there's no extra strain on it. It's much worse for the motor, the controller and the battery when you go slow than when you go fast.
There's no way that the controller can record anything about derestriction, so if any settings are changed and then they were put back as they were before, nobody would know except the person that did it.

I suspect any changes to power/speed might be possible if there is a data cable from the controller and we only know what wiring it has when some one does some surgery. As yet no one has said whether or not they have tried the lcd button combo's to see if it goes in to advanced settings.
I have noticed this... but the speed on GPS never matches the speed on the LCD. The LCD always has a slightly further distance when compared to the GPS at the end of my journey.

Very little difference between Crossfire-e and Kudos @ 15amps for Hill Climbing. Both are excellent climbers. I prefered the overall experience of the Carrera due to the Torque sensor system which gives full power even in ECO mode if you stomp on the pedals.
The Kudos did my test segment in 9:01 and the Crossfire-e in 9:05:

Both were better than my Greenway Maxdrive for hill climbing until I got hold of a programming lead and upped the current on the Maxdrive. I've not yet had a chance to try the Greenway on my test segment with the new battery and reprogrammed controller, but expect it to be quicker by maybe 20 seconds over the 9 minute segment.

I will do. Unfortunately I had an "off" yesterday after hitting a greasy patch, so nursing some bruises - it probably won't be for a week or two that I do that segment with the 30Q battery pack decent current.
I can tell you that it was 10:40 on the Greenway Maxdrive with the orginal battery and and more conservative programming. Over 15% slower than either of the hub drive bikes.

That's interesting. The only objective test results I've seen before that involved side-by side tests up a mountain were done by a German e-bike magazine. The Panasonic and Bionx hub-motors trounced the Bosch and other crank drives in every performance characteristic, including efficiency!
Just did the segment today on the Greenway (Maxdrive) with 30Q battery pack - 20amp Limit with 80% keep current (equivalent to 16amps I guess).
Result was 9:37 seconds. Now the weather was shocking (rain) and I did have a pannier on the back with maybe 8kg of stuff in. This was 36 seconds slower than the Kudos Tornado with SWX08 hub motor over the same 9 minute route @ 18amps.
I want to try it again with 100% keep current (20amps) and better weather.
But for someone moderately fit (although heavy, I cycle 25+ miles regularly on a road bike), I can't see that there is a massive advantage on the road with hill climbing for crank drive over a hub drive.
If had weaker legs, I can see that the crank drive would be able to pull me up the hill where the hub drive would struggle as the motor drops out of its efficiency zone and stalls.
I reckon at under 12% gradient, CD bikes don't do any better than a good geared hub assuming the same current draw.

Don't forget that not all hub-motors are equal. Some can out-climb the regular CDs by a significant margin, and be efficient while they're doing it.
Just about to pull the trigger on a Carrera Crossfire-E from Halfords through cycle2work and been trawling the internet for a solution to derestrict it which has lead me here...
I'm surprised there isn't more information on it tbh! I would have expected this to have been bottomed out one way or another by now. Has anyone approached one of the retailers who sell modified/derestricted bicycles to ask if they can shed any light on the matter?

All 3 of my ebikes can be 'marginally' de-restricted. I didn't know about that at the time of buying the first one. Consequently, I never made that mistake with the other two. There are good bikes that de-restrict for less money than a Carrera. A few of them are being sold on here.

There's loads of info on the forum about restriction methods. We rely on owners testing out those methods and finding out what works. Until now, nobody has posted any information about anything they tried, so we're all in the dark.
I am looking for a commuter that can handle 14 miles each way. A bit of rolling with very little punctures would be fantastic.
Would you mind suggesting few please?

I am having a hard time convincing my employer to sign up for C2W and probably have to fork out in one go.
