Thoughts on Carrera Crossfire-E

[LeighPing]

However it looks like in future if I have to get a new tube then it's up to Halfords for them to remove the rear wheel for the job to be done.

It was a bit of a mission, but I managed to change tubes and tyres without totally removing the motored wheel. Undo the wheel-nuts and slip them both in past the nut on whichever side is easiest. Then you can feed it onto the rim.

Take pics before you start. Then you'll know what goes where, when you reassemble it.

Thanks for that bit of advise but I am not sure if the wire going to the rear wheel will be long enough but I will try it and see.

Do you know what size of tools I need to untighten the nuts on the rear wheel?

Unless unattached, my wire is very short too, just enough to lift it out a bit and squeeze a tyre past it. I just grabbed spanners from my toolbox until one fitted. Good luck and don't forget the pics.

Whilst you are at it, change the rear tyre for a Schwalbe Marathon Plus tyre - it will reduce the likelihood of having to fix a puncture out on the road.

I decided to replace both tyres after my rear wheel puncture - I was lucky in that it was a slow puncture and I had enough CO2 to get me home - but no way I could have fixed it at the road side.

15mm Spanner needed for rear nuts IIRC (or was it 14?).

You also need some snips to cut off old cable ties and new cable ties to replace the ones you snip off.

Bugger I had no assist when leaving work tonight in the rain. There is a new rubbing noise coming from the crank area, sounds like something has come loose. Will investigate tomorrow once its light.

UPDATE
Nothing obvious wrong, took the plastic battery thing apart covering the electronics, all wires seem good. Panel comes on, the walking assist works. All the screws were loose inside though, the 2 holding the battery prongs on was especially loose, so that maybe accounts for the cutouts.
I suspect the torque sensor & am dropping it into halfords tomorrow. I dont hold out much hope to be honest.

Having been in discussions with Halfords customer services, my Crossfire-e is going to be sent off to the "Manufacturers" for testing and fault finding. It has now cut out on me 9 times in two months.
I'm going to be without it for "2-3 weeks" - no courtesy bike will be supplied.
I will update the thread once I have an update.

Just found that Halfords are now selling the official spare battery and charger for the crossfire-e, £350 for the battery and £36 for the charger...all we need now is a 10% flash sale and pickup from store present your British Cycling membership for another 10%, that'll bring the battery down to an acceptable £270

Charger isnt too bad, battery is dear though, but I guess thats too be expected. Personally I think the existing battery will outlast the rest of the bike!
It seems impossible to buy hesc suntour bits anywhere, google shows up absolutely nothing which I find a real concern to be at the mercy of halfords.

Hello, I've just ordered my Crossfire-e from Halfords after reading this topic, thanks for all the info I just wondered if the new control panel can be changed to mph.

 

[redcup1999]

Yes. Just press and hold the "i" key for around 6 seconds to toggle between KMH and MPH.

Enjoy the bike when it arrives!

Hesc bits? Suntour tend to do standard components that are upgraded from eBay.

That battery is a bargain compared to replaced Bosch ones.

Well I got my faulty bike back from halfords today, they had it 3 weeks or so whilst it was sent away. It looks like the rear hub motor has been swapped out and also the front chainring/sensor.
I cant fault them really as I didnt have any proof of purchase, although a failed motor at 1000km isnt great. Fingers crossed it doesnt pack up again.

Sorry to jump in on this but would this bike be any good for towing 2 small children in a trailer up a fairly steep hill? Have posted my own thread but thought I might get a quick answer here

 

[Jack.Mackenzie]

I absolutley love this bike to bits, but recently I have noticed a strange jolt happening when I am in 8th gear, it happens every few revolutions, I have inspected the derailleur, the rear wheel and crank but cannot gind anythinh adrift.

Has anyone else had this issue or even a sinilar issue with another bike?

Check the chain. 8th is a tight bend.

 

[Ultrafunkula]

Ditto the chain, it maybe that the rear cassette being new with it being tight bend the chain catching the tooth profile now and again, it may settle as it wears. Check alignment of derailleur very precisicely it'll only need a slight amount off to be able to lift the chain up the tooth before load comes on and drops it back down.

Most likely rear derailleur adjustment. I wouldn't trust Halfords to get that right. have a look at the various Youtube videos of how to do it.

 

[Warwick]

It could also be a couple of links in the chain stuck together. Try wiggling every link joint and see if any are fused. If they are and it's not too bad, apply oil and leave a while and then try again.

This only happens in the higher gears where the chain has to complete a smaller circle to get round the cogs.

I get the same on my Crossfire-e, just in 8th gear. I need to look closely at the derailleur to check alignment.

On a different note, I've been trouble free since getting the bike last August until 2 weeks ago, snapped a spoke on the rear wheel just inside the spoke nipple. Replaced it, and then on Saturday, snapped 2 more withing an hour whilst out on a ride (both snapped just inside the nipple as before)...any ideas why ? I've been just running the lowest assistance (25%) at the time of it breaking. For info these are 13g spokes with 4mm nipples (tillercycles.co.uk)
