Affected by the recall: the Hercules Rob Fold SL with a carbon rigid fork; pictured here is the Model 10.
​Please note: Hercules GmbH is recalling the Hercules Rob Fold SL e-bike models due to safety concerns regarding the carbon forks fitted. All models are affected; the manufacturer is offering a free replacement or a refund of the purchase price.

As the Hercules GmbH As recently announced, there are problems with the forks on the Rob Fold SL electric folding bike from the current model year. More specifically, with the carbon fibre ones. These can “fail under certain circumstances, which may result in a loss of steering control.” In other words: the forks can break – and you really don’t want to imagine what would happen then.

However, anyone who is dissatisfied with this option may also return the bikes, including the battery and charger, in exchange for a refund of the purchase price.

Sebastian Brust was born in 1979 and was originally socialised on his grandmother's folding bike, but has mainly been riding studded tyres since his fifth birthday. Loves all kinds of bikes - and merging with nature. Believes that disc brakes are much safer today than they were 15 years ago and thinks he has helped with his brake and pad tests. However, the trained vehicle technology engineer very much regrets that the bicycle industry is orientating itself on what he considers to be the wrong ideals of the car industry. At BIKE, he corrects, produces and organises digital content on the website.
