Brompton bikes has issued a recall of three year's worth of bikes, stretching from May 2014 through to April 2017.
According to the folding bikes company, the recall is because of a higher than expected rate of failure in the third party FAG bottom bracket cartridge BB66.
According to the video posted on the brand's website, the amount of failure isn't incredibly high, but high enough to force the brand to act.
To this end, Brompton says the failure is only one in every 5000 but encourages all owners to voluntarily return their bikes for the replacement fitting free of charge.
The brand makes clear that the part and the bikes meet international safety standards, but Brompton doesn't feel comfortable not acting.
