Carrera Vulcan E-Spec - torque sensor problem (E21 error) 

rcfanaticdublin Good news - maybe try telling them it is a common failure and it should really be a warranty replacement. The new sensor is a much better design with the plastic guard which prevents more dirt ingress 👍

@@IceReef, I did mention our conversation to the rep...I think that's the reason he made the offer. don't worry...i did not mention who i got the information from.

No problem. I'd always advise keeping the battery and display unit indoors at all times. Always keep the plastic protector slid over the contacts when you remove the display unit.

I have a similar E42 fault, couldn't solve the fault, please assist

The hub motor anti rotation washer on my 3 year old Crossfire broke in two 2 years ago but I wedged it back in and it worked until recently. I ordered another from halfords and it has taken just less than a month to arrive, which is not bad because their suppliers were out of stock. The point I make though is that I called in after a couple of weeks and saw a different mechanic from the very helpful one I dealt with at first. He told me that they might not be able to get the part at all but I think changed his tune when told that this was a relatively expensive halfords own make bike (not e bike) and it was unacceptable to be told that they could not supply spare parts for a 3 year old bike which was unusable without the part. Be very firm and insist halfords obtain the part. My rotation washer does not appear to be available elsewhere, being 20mm diameter and grooved round the circumference. Tell them you will take it further and complain to the Chief Exec in writing if they do not get the part for you.

Hi, Where do I buy a new battery for this bike please?

Hi Jamie - thanks for your kind comment. I do now have a Facebook page for the channel - button link is at the top of the channel page. If you click that you can drop me an email directly. Alternatively, the link to my email is on the channel page as well. Let me know if you have any problems, but look forward to seeing you on the Facebook page.

i now realize the sensor on my first bike, was the old type early 2017 although purchased mid 18?, even though the bike was bought later than than ice reef, (his video was my inspiration for purchase,), then when everything failed and HELLfords gave me a new bike new bike ! now same anti rotation lugs failed as in the video same no parts , local Halfords say they have 42 tooth chain ring sensor from crossfire, or wait 6 months or more refuses to give me the sensor from his parts, say it will upset his stock i can have, fitted, i would have it on a temporary basis awaiting 38tooth as standard, but it's a take it or leave tit choice ,Halfords ,mmmm.pursuing refund ..

There is a guy selling a new one on Ebay as of today!

I have been waiting 6 months also to have my rear hub rebuilt but i am fortunate to have a spare Carrera Crossfire-E bike.like the channel so i subscribed 👍

Do u get an answer? U have to hold two buttons down on display for a few seconds and then it zero's.

They should be able to tell the issue immediately based on the error code being generated. If the screen is not working, it is often just a loose connection. I did another video on this very topic - should be in the link in the video description!

@@IceReef Thanks for your quick reply much appreciated, there have been further developments, when they were trying to fix the bike other random codes appeared, including 04 which is to do with lights - strange as the bike doesn't have any! They have replaced the controller, TS, and took apart the TS and ECU and found them to be full of a residue from a 'maintenance spray', they think it is the Muc off spray 94 (a bit like GT85) and advised not to use that near the bottom of the bike, just water. Going to test it today. Also to leave the battery abd controller in place covered with a rag when washing as that is a better water seal. Halfords do seem to have worked very hard to solve the problem.

It is quite buggy unfortunately. Many issues around the torque sensor and slightly loose fitment of battery against holster and the screen against the display holder. I would advise to strap down the battery with Velcro straps to the holster, and also tie down the display screen to the holder as tightly as you can as this can often be the cause of the errors.

@@IceReef Halfs gave me a new bike in the end let me keep the old battery, i going to change the gears as you did next,the cut out for me is after i work the bike hard,then power of descents, terrain does not seem to impact, i ride some level very rough tracks,thanks again i am becoming a Vulcan fan regardless ,.after your first vlog , big issue 5 display holder cracked ,that how hard i ride ,replacement 3 month or lots of improvisation.

Hi. I did get a replacement. I ordered it over the phone from Halfords and picked up a week later in store. I fitted it myself and it did sort out the issue.

Hamza Ahmad Good to know they replaced it without an issue. Unfortunately mine is second hand!

I think your best bet would be to ask for the replacement in an Halfords repair shop as they have contacts with suntour directly

@@mughal_gtown I've spoken to the dealer in the UK who, unfortunately, cannot sell to me direct, so am awaiting confirmation from Halfords if they have the part, and how much they are going to charge / rip me off for!

@@IceReef I had my torque sensor fail on my Carrera Crossfire E a month ago, and Halfords told me that a replacement wouldn't arrive until December! Richard Underwood at Powerbikes got me one within a couple of days for £30.99 including postage. Give him a call on 01387 270209 if you aren't sorted out yet.

Hello Hamza, Just wondering...how long have you had your bike and how many Mile's/klm's? before your problem with your bike.

Jase Roberts Hi - call up your local Halfords and ask them to order you in a torque sensor (they have it down as either a crank or speed sensor on their system). It is around £32

@@IceReef thanks for that

Your sensor wire has broken just connect them (Red,green,yellow and black)

Hi Hatim - you can generally get them from Halfords if you call their service department. Alternatively, I would prefer looking at Ebay as there are often one or two of the same style of battery available much cheaper

I haven't opened up the crank unit yet but intend to as it is probably filthy in there and could benefit from a clean with some contact cleaner

Hi - I think you will need to but the torque sensor unit. Ebay is your best option - try this listing here - www.ebay.co.uk/itm/133601950985

mark jakeway hi mate, just seen your comment, have you managed to order one of these sensors from Halfords then ? I’ve noticed your comment is 3 weeks old so quite recent. I have been trying for weeks and keep getting fobbed off telling me they cannot get me the part.

@@freeenergy2456 Hello, sadly since then I had a number of other errors, but Halfords can get them, in fact my local store has a number in stock now! So the full story it went back as above and they took three days as they kept getting error codes, the changed the LCD head unit as well as the sensor, and the staff there were great (Durham branch) but four days after getting it back it actually went again this time with error 42! This time when I took it back they just offered me a full refund straight away and I upgraded to a Raliegh ebike with a mid drive motor. A shame really as the Crossfire was a decent bike. Keep pestering them and take it higher.

mark jakeway thanks so much I will try and call today

That is good news that they will do it under warranty....ridiculous though that it is taking that long - must be to source the part, as the fitment of it took me 5 minutes!

@@IceReef , Thanks for your help buddy...Though I suspect that the email I sent to Suntour may have some thing to do with it😏

Don't buy it! I've had nothing but problems with this bike since new. I've spent more money on keeping this bike running than my motorbike.

@@tangerine0072000 I would say that it is only worth getting if you can find a second hand version for a good price - be looking at around 400 if you can find anything. Otherwise, as stated above, the system is trying to be too clever for it's own good, and is plagued by a few glitches and build quality problems.

Hi - if you look at the description underneath the video, the link is there... **LINK TO SUNTOUR HESC MANUAL** the-bionic-cyclist.co.uk/2017_bike_manual.pdf

rcfanaticdublin Hi - what appears to be the problem? Do you have an error code on the display panel which you can provide me with?

@@IceReef , Sorry my problem is a mechanical failure at the crank...the sensor plate has broken and is rotating with the chainring. I have been having occasional problem's with the bike switching off...no error code's. thank's for the promt reply.

rcfanaticdublin I managed to get the replacement torque sensor from Halfords - £30.99. They order it in and you can usually collect within a week. Straight replacement with three screws. I’ll show installation in another video. That should solve your problem - Halfords have it listed on their system as a crank sensor

@@IceReef , thank's again...i think there's a bit more damage on my machine. Oddly the sensor still work's...but the crank has developed some dragg when i try to back peddle.

You can try speaking to Suntour Europe via their website, but otherwise it will only be available from Halfords

Hi mate I’ve got exactly the same problem, they are telling me they cannot get the sensor so my bike is pretty useless now

@@freeenergy2456 Go to the Suntour website and contact their European office and ask about parts support. Explain the situation and they should be able to point you in the right direction

WeZ Did Halfords tell you what the specs of the new model would be? I’d only say it would be worthwhile if they include a bigger capacity battery and somehow increase the range as it isn’t great in everyday conditions.

WeZ In answer your your initial question, the best way to protect the sensor would ideally be to have metal lugs instead of plastic, but that would be a custom build with a bit of aluminium plate or something similar. The new sensor I just got from Halfords does have a new plastic dirt guard at the bottom which is much better than the original design

@@IceReef No I was only told a new model was on the way by a staff member.. Although, I've seen nothing on the net.

@@IceReef Thanks. At least it can be fixed. I was looking at the Riverside 500, but i'll stick with the Vulcan as there's more info available from persons like yourself.

@@IceReef Just got the new model. The battery is physically smaller, but rated at 417 watts (same I think). The motor is stronger, rated at 60 Nm. I'll only be using it 4 times a week, on my 30min Gym ride, so that i've done my cardio on the way. I'll also do a 1hr 30min ride on my off days. I'm not hardcore. So the battery is good for me. (i hope) I just need the help on the hills at the start of my rides. They are nasty... Wez
