Recall of DublinBikes electric battery packs due to overheating

— 396 users renting battery packs warned not to use or recharge them.
— Half of 1,600 DublinBikes have ‘hybrid’ electric function. 

Electric battery packs for DublinBikes, launched just three months ago, have been recalled due to overheating incidents in France.

JCDecaux, the advertising company which runs DublinBikes for Dublin City Council, said that there has been three overheating when charging incidents in Lyon.

The ‘hybrid’ battery system includes electric bicycles mixed in with the fleet of non-electric DublinBikes, and, users who wanted use the electric assistance, had to order their own personalised battery pack and pay extra per year.

When launched, it was noted as a strange setup as users would have to charge the batteries at home. Home charging was where the issues happened, JCDecaux has confirmed.

JCDecaux said: “Further to an issue arising in three individual electric bike batteries in Lyon a decision has been taken by JCDecaux to recall all electric bike batteries for the three existing schemes in Dublin, Lyon and Brussels. The three battery incidents in Lyon involved battery overheating during the charging process.”

“The identified risk is overheating which causes the battery circuit board to short circuit. The estimated incident occurrence rate is 0.003 per thousand. As user safety is our top priority, we have stopped distributing batteries to new subscribers and are asking e-dublinbikes users to stop using or recharging their batteries and we are recalling the 396 batteries currently rented in Dublin,” the company said.

JCDecaux said: “As soon as the battery manufacturer has inspected and made the necessary technical and firmware updates so that they can be independently certified to EU standards, the batteries will be returned to users. e-dublinbikes subscribers will be contacted by call centre staff to explain the returns procedure”

It added: “JCDecaux apologises for the inconvenience to e-dublinbikes subscribers and assures them that our staff are doing everything possible to restore the e-dublinbikes service as quickly and efficiently as possible.” is reader-funded journalism. That means it's funded by readers like you.

Subscription drive update: reached its target of 270 subscribers by the end of August -- thank you to all who have helped! Our new target is to have 300 subscribers by the end of 2022 -- originally this was hoped to be exceeded by the first year of running the site full time (end of October).

If you can help push above 300 subscribers, please subscribe today for €5 or more. If you have already done so -- thank you!

Please remember, every month there's a natural drop-off in subscriptions due to people getting new cards, cards stolen, Revolut not topped up etc.

*** is a reader-funded journalism publication. Effectively it's an online newspaper covering news and analyses of cycling and related issues, including cycle route designs, legal changes, and pollical and cultural issues.

There are examples, big and small, which show that the reader-funded or listener-funding model can work to support journalism -- from the Dublin Inquirer and The Guardian to many podcasts. To make it work for, it just needs enough people like you to believe!

Monthly subscriptions will give's journalism a dependable base of support. But please don't take free access for granted. Last year had an average of 15,800 readers per month and we know our readers include people who cycle and those who don't, politicians, officials and campaigners.

I know only a small percentage of readers will see the value of keeping this open enough to subscribe, that's the reality of the reader-funded model. But more support is needed to keep this show on the road.

The funding drive was started in November 2021 and, as of the start of June 2022, 250 readers have kindly become monthly subscribers -- thank you very much to all that have!

But currently, it's only around 1.6% of readers who subscribe. So, if you can, please join them and subscribe today via

  1. thankfully only a minor setback it was always a strange system the way it was done and like anything else some batteries can simply fail.At least they have come out in the open about it.

  2. The new bikes are much heavier & tougher to cycle than the older ones despite having 7 gears as opposed to 3 on the older models. It seems to me they’ve gambled on a bigger uptake of electric bikes than they’ve achieved. They’re a tough cycle without the batteries especially for an aul fella like me.
