Bicycle accessories & small parts: lights, bells, racks, locks, tools, bottle cages, and more for your bike
In this category, you will find everything you need in accessories! We offer smaller components such as lighting or bells, but also racks, bottle cages, water bottles, locks, and especially special tools for singlespeed and fixed gear bikes. We provide a wide selection of accessories for your bike. If you are looking for bicycle accessories like lighting, we offer various systems from Knog, Busch & Müller, and Sigma. Most of our bike lights are USB rechargeable and easy to mount and dismount. Of course, we also have spare parts for your bicycle lighting in our range. For accessories like racks and front racks, we carry different systems from manufacturers such as Pelago and BLB, which we have good experience with. In particular, the Commuter Front Racks are especially reliable and high-quality luggage solutions. The racks from BLB offer an excellent price/performance ratio and a wider range of applications, making them an ideal addition to your bike. If you are looking for additional accessories like bike locks, we mainly offer U-locks from Kryptonite. These are especially secure and provide optimal theft protection. Almost all Kryptonite locks come with accessories such as a frame holder, making them very easy to attach to your bike. We also have a large selection of special bike paints from Spray.Bike, which allow you to paint your bike simply and individually. The paints from Spray.Bike are specifically developed for use on bicycles and accessories and are very easy to apply. To complement the paints, you will also find accessories like stickers from Reflective Berlin, which can give your bike or accessories a personal touch. These stickers are made in Berlin, look great, and also increase your safety on the road. We also carry other accessories such as bells. Our selection includes particularly small bells like the Knog Oi or 6KU Classic, as well as many models from the Japanese manufacturer Crane Bell, which has a long tradition. Indispensable workshop accessories with a special focus on tools for singlespeed and fixed gear bikes, such as chain whips or lockring tools, are also available in our range.
bicycle bells
In busy cities, there is a lot of hustle and bustle in traffic. As a cyclist, you should be especially attentive and anticipatory when riding here. A loud bell on your bicycle can be quite helpful in alerting less attentive road users to your presence. In addition to functioning brakes, reflectors, and at least a portable lighting device, bicycles must be equipped with "at least one loud-toned bell" according to the German StVZO to participate in public road traffic! At BIKE PUNK BERLIN, we offer a wide range of bicycle bells in various sizes, colors, shapes, and mounting options. We have bells that can be discreetly placed on the handlebars, as well as bicycle bells that make your bike a distinctive and stylish design feature. Make yourself heard on the road with a bell from our SHOP!
Bottle Cages
Anyone who bikes actively needs to stay properly hydrated. A bottle holder attached to the bike ensures the safe transport of your water bottle and quick access when needed. There are bottle mounts for every type of bike, for every purpose, and for (almost) every bottle type. They come with or without screws, with side access, made from aluminum, carbon, or plastic. With our range of bottle holders at BIKE PUNK, we make sure you have your water bottle quickly and securely within reach during every race, tour, or next adventure with your bike — because staying well-hydrated is essential for sustained performance, optimal results, and maximum concentration! We offer rigid bottle holders from brands like Tanaka, DEDA Elementi, Lezyne, Cinelli, and Genetic. Various colors and shapes allow you to perfectly match your bike’s geometry and your personal style!
