April 25, 20178 yr Hi Ladies/Gents, I appreciate there is another popular thread that covers the subject to an extent, but it doesn't solve the issue definitively, and has been dead for a while now, so i wanted to start up a new thread and get the latest info on the subject... Can you delimit the Carrera Crossfire E!? I've had mine for 3 months, I'm coming up to 1000 miles and i really enjoy it, but I would dearly love to be able to cruise at a more potent 20-25mph, 15.5mph is just a little too slow, and the bike itself is too heavy to peddle any faster without gravity or wind assistance! If anyone has managed to crack this conundrum then please share :-) FYI, yes I am aware of the legal ramifications, I'm looking for solutions to the question, not for legal advice. Thank you :-)

April 25, 20178 yr Author You can delimit, but your warranty will be invalid. Sent from my SM-G920F using Tapatalk I'm perfectly happy to forfeit my warranty, do you have any specific info on how it can be carried out? I've been told its a mixture of software and hardware, and the battery manufacturer has told me directly that its impossible, but then I suppose they would!
April 25, 20178 yr People keep coming on here asking the same question, but nobody that owns one has made any contribution to furthering the knowledge base. Until we see which motor connector you have. what the motor controller looks like or which LCD key combinations have already been tried, we can't help.

Until we see which motor connector you have. what the motor controller looks like or which LCD key combinations have already been tried, we can't help. I think, with respect, people that already own one and are asking the question, are, like me, asking for assistance from someone who has already successfully delimited their own, and therefore will be aware of the motor/battery set-up. Assuming that no one has managed this yet, I'll get some pics up of the various components so that anyone with a technical mind could better advise...I'll get these up shortly....
April 25, 20178 yr Author People keep coming on here asking the same question, but nobody that owns one has made any contribution to furthering the knowledge base. Until we see which motor connector you have. what the motor controller looks like or which LCD key combinations have already been tried, we can't help. In order we have: 1; The LCD display. Only an On/Off button on here. 2: The controller. This has +/- buttons to toggle assist mode, a button to apply a small peddless assist for walking with the bike, and a screen brightness button. 3: A very muddy motor hub! 4: This is the connection from the controller to the motor to disconnect when removing the rear wheel. There are no other notable exterior components. Anything that registers the rotations to determine speed must be self-contained within the motor hub itself. In terms of key combinations, the only one I am aware of + and - to reset trip distance. Thanks in advance.
April 25, 20178 yr The controller is likely in the base of the battery. There are other key combinations (scattered through various threads on here), but nothing that seemed to enable limits to be removed or wheel size to change.
April 25, 20178 yr Author Thats interesting to know, I'll try to hunt down the various key combinations.
April 25, 20178 yr OK, so we're one step further forward. I can see that the motor connector is not a common one. That doesn't rule out using a different controller, but makes it more difficult because there would be 9 additional wires to solder. That wouldn't be a problem to anybody that knows about wiring/soldering, but it does make it difficult to test the motor speed by powering it with the cable from another bike. Derestriction would be futile if it's a 180 rpm motor. Another good connector to look at would be the one that connects the display to the controller to see if it's a standard one. You need to pull it apart and photograph the pin arrangement. the system has to be programmed somehow- either through that connector or there must be a programming header on the controller. It would be fortunate if the Bafang or similar programming leads worked with the Suntour system. I think that there's a fair chance that it could work even if that means adaptor cables.
April 25, 20178 yr You can delimit, but your warranty will be invalid. Sent from my SM-G920F using Tapatalk The question being asked is how ? You say you can delimit it have you tried or is it just a mere sweeping statement, if the latter then your post is useless.
April 25, 20178 yr As mentioned know one who owns one has actually come on here and said you have do this or that. As d8veh has said if hub rpm was known that would be a start. Opening the controller to see the wiring may give a clue, is there a potentiometer attached to any wiring ? I have 2 KT controllers which have a speed link, disconnect the wire link and you get 30% more speed. Also has anyone tried the lcd switch buttons, toggling the buttons can some times enter into advanced settings. They all operate a bit different, a long press 10secs or so of 1 button or a combo of 2 can allow entry in to advanced settings. Or this set up may just be programmed not to allow any tinkering, is there a data cable tucked away at the controller end. Until someone is brave enough to delve deeper then the owners on here will never know.
April 25, 20178 yr The question being asked is how ? You say you can delimit it have you tried or is it just a mere sweeping statement, if the latter then your post is useless. Actually clever clogs he said 'can' it be delimited. I was merely stating a fact. I have a crossfire and see no reason to delimit. as I can cruise happily above the 15.5 mph. After 3 months of owning the bike, I would not jeapdise the warranty, I believe the deresrictions are done via the computer, but I won't messing or suggesting until my warranty is up.

April 25, 20178 yr The fish are biting again today . Merely stating a fact that it can be delimited !!!! Which as of yet no one who has one has come on here and said they have actually done it.
April 25, 20178 yr I'm hungry.... the thing is with these bikes from what I know, is that you have a 2 year warranty on the motor and battery. If you derestrict the bike and something happens to one of the above then you are out of pocket to the tune of £350 each item. I don't believe this bike has been on sale for 2 years as yet, and the recent upgrades on the relaunch model is only 5 months old. So de-restricting the bike is a bit premature in my opinion. The motor is capable of 400+ watts, but limited to 250. Sent from my SM-G920F using Tapatalk
April 25, 20178 yr Which dealer is that? The bike is only sold through halfords? Sent from my SM-G920F using Tapatalk

April 25, 20178 yr The motor is capable of 400+ watts, but limited to 250. Sent from my SM-G920F using Tapatalk Your hub is probably already giving more then 400w power, if you have a 15a controller @ 36v power output will be over 500w on full power. The 250w continuous rating is only to comply with the law and eapc regs other wise your controller would only be max rated for 7amps and wouldn't get you up a large speed hump. There is no harm having a go at derestricting to see if it is possible just to find the settings or process, then put it back to stock settings for piece of mind. Edited April 25, 20178 yr by Nealh

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.
April 25, 20178 yr 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.
April 25, 20178 yr 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.

April 27, 20178 yr I've read a few people say their Crossfire's cut out higher than 15.5mph, not much more just up to 16.8mph.
