The Dutch print service Van Zijp Technology 3D Print Services sells a whole range of accessories and gadgets for a wide variety of electric bikes. The mudguard extensions, for example, are a big hit (since May 2025 also for the new Plastic mudguards as with the ST5 Pinion) but also horn covers, battery device wall mounts, a battery transporter for the luggage rack or various mobile adapters for the stem are on offer.



Another provider of add-ons and gadgets for the Stromer models is the Swiss company tekku.


The Dutch electricity trader also offers Mudguard extensions for €20.
