Carrera Crosscity Folding Electric Bike 2017 - Splitting Cracked Rims

[raleighnut]

Look into whether the back wheel (with the built in motor) can be rebuilt

It can, trust me it can. Whether you can find a shop with someone who can do it is the hard bit.

If Warlands can cram an Alfine into a deep section carbon rim for my Brompton then they can almost certainly rebuild a wheel onto a motor rim... they do do the Nano conversions too so they've built those kind of wheels before.

I've had exactly the same problem, my rear wheel split six days ago (from date of this post), almost exactly a year from when I purchased the bike from Cycle Republic.

I use it almost daily, I reckon maybe 9 to 10 miles a day and I'm almost always carrying stuff using from 1 to 3 panniers when I do the weekly big supermarket shop.

Cycle Republic opted to actually rebuild the wheel using a thicker rim and thicker spokes - dunno how much its going to cost me but I'll gladly pay because my other options are my cyclocross commuter with no pannier rack or my brother's 2010 Scott aspect mountain bike with a pannier fitted, no where near as fast or easy as the Carrera!

I think that such a rapid rim wear is pretty bad. I use wheels built by a top-notch builder on my full size bike and these wheels last until a rim is close to wearing off or an accident occurs. These wheels last 10y/20,000 miles or so before I decide that the rims are worn enough and I ride whole year, through snow, mud and salt. If you recalculate this to 20" wheels, it is still 7y/14,000+ miles.

If I may speculate, if a brake rubs against the wheel and you power the bike with your own effort, you will notice this and take action to fix the brake. Maybe if you use the electric power you are less likely to notice the problem. Was the unusual rim wear accompanied by an usual brake pad wear? Did you change the pads many times since you got the bike? Was there anything particular about the pad wear when you looked at them? What brand did you use for the pads?

I just got my Carerra Crosscity E back from Leeds Cycle Republic, they rebuilt the back wheel using a Halo T2 toughened BMX rim and special custom sized spokes to accommodate the hub motor. They also replaced the tyre and inner tube, total price: £82.30.

RE: Question about how long a bike wheel should last for before it splits

I decided to start cycling to work in July 2017. In that month I bought the 'Carrera Crosscity Folding Electric Bike 2017' from Cycle Republic.

It was all working fine until February 2019 (about 19 months later) when the back wheel split.

I phoned a Halford's store to ask how much a new wheel would cost, and they asked me if I had visited the store earlier to ask the same question, as some else had reported the exact same issue with the 'Carrera Crosscity Folding Electric Bike 2017' and they were aware that there was a backlog of orders for the back wheels for this particular model.

I ended up booking an appointment with Cycle Republic for repair, and they informed me that my only option was to buy a replacement back wheel, which was £150 (this is because it is an electric bike and the motor is built into the wheel).

When I collected the bike, and asked for the wheel with the split rim back, the nice chap who gave me my repaired bike back said he didn't know which one was mine because they had two wheels in the store with split rims from a 'Carrera Crosscity Folding Electric Bike 2017' as they had also carried out a replacement on another customer's bike that day.

At this point it seemed like the split might be more related to do with a poor built quality than my usage. My cycle commute is about 15 minutes, which I make everyday weekdays, apart from Dec/Jan.

Cycle Republic customer service has told me that they aren't aware of any issue with the 'Carrera Crosscity Folding Electric Bike 2017' and that the split rims occur with normal use, and are more likely to occur with electric bikes and bikes with 20" wheels.

Has anyone else had this issue with a split rim on a electric/20" wheel bike after 19 months? And/or would this be considered reasonable a wheel to only last 19 months?

YIKES - Looking at that picture I realised that yours was a lot worse than mine and I was carrying some pretty weighty stuff on my pannier rack on a weekly basis!

after enjoying 18 months of Carrera Crosscity Electric Bike, i got a splitting rim,

I took it to Halfords - Bordesley Green (Birmingham)- and had to pay £150/= to replace
the rear wheel, i was not given the option to replace the spit rim itself but rather the complete rear wheel.
now I have a spare rear wheel with an electric motor but also with a split rim,

I am hoping to replace the splitting rim, and was just wondering
how to procure a new rim which would fit with Carrera Crosscity Electric Bike.
now thanks to (VinylJEDI) posting, i know now that "Halo T2 20" BMX Rim 36h with CNC braking surface" would do the job.

I would post another update once I have replaced the spliting rim.

Kind Regards

Had the same problem and fixed it with the following

HALO T2 rim 36H CNC 20 inch rim £35
https://www.tredz.co.uk/.Halo-T2-20-BMX-Rim_102045.htm

Spoke wrech tool - spokes was size 13. most the tools cover 10-15 gauge.

View: https://www.amazon.co.uk/slp/spoke-key/7ec23pvtpgte3d3


Then the tools the removal the wheel

And voila job done, did take about 2 hours because of the wheel alignment.

Please youtube about removing the spokes and wheel alignment lots of videos on there. I had to watch about 10 videos until I was comfortable.

My Gtech is about ready for a new rear rim now (6 to 7,000 miles stop start commuting and never really cleaned!).

Will have to give it ago, I suppose for me that would be the benefit of disk brakes BUT it's over 4 years old and ridden through winter so not too shabby really.

Hi, could you tell me what length spokes you used as I'm doing the same conversion/wheel rims as you . Thanks. Cols.

 

[spy2134]

Hey

I used the same spokes from the original wheel

Sorry not a bike mechanic, so not sure the actual size of them

Let me know If you have any other questions I'll try help out.

It was a switch from 1 wheel to the other

Exact same thing happened to my carerra crosscity e. They tried to blame the brake pads and usage as well. But I get my bike checked regularly and a month prior to the rim splitting I had been given the all clear on the entire bike. They replaced the bike under the consumer rights act, but wouldn't pay for my injuries until I sued them under the consumer protection act. Apparently they don't run tests on all their bike rims that would identify micro fissures etc. Cutting costs. But that makes them liable.
