Kink 2025 Switch BMX Bike - Astro Red

The Kink Switch is specifically designed for riding street and an intermediate to high level bike. This bike features a Mission Pace sealed freecoaster hub, 4 piece Chromoly handlebars, Mission nylon pegs and shorter offset forks to make this one of the best street specific bmx bikes available.

What parts are on the Switch BMX bike?

The Kink Switch BMX bike features a 100% 4130 Chromoly frame making it both lighter and stronger than an equivalent frame made from High Tensile Steel frame. The forks are the Kink Trident which are 100% Chromoly and feature tapered legs and are connected with a Mission sealed integrated headset.

This 20" BMX bike has many high end components including a Mission Bond sealed rear cassette. This combined with the Mission Bond sealed Female front hub are both laced onto Mission Mylar double walled rims with 36 spokes. These are running on Kink Wake 2.45" wide tyres with a low profile wrap around tread that is ideal for street riding.

The Kink Ridge tubular BMX cranks are made from Chromoly and are 165mm long. These are shorter than the cranks on other bikes in the Kink BMX range, it's widely assumed that shorter cranks enable you to rotate the bike faster making spins into and out of grinds and other tricks feel easier. These have a 19mm diameter, 8 splined spindle and sealed Mid sized bottom bracket bearings ensuring your ride is maintenance free. Completing the drive chain is a Mission Locator 25 tooth aluminum sprocket and Kink Hemlock pedals.

Up top there's Kink Form flangeless grips on 9" rise Kink F900 4 piece Chromoly bars which are clamped to a Kink Bold HRD top load stem. The Mission Token brake lever connects to the Mission Cease V2 rear brake via a Mission L4 Linear cable to give you good stopping power.

The Kink Switch is fitted with a Kink Ericsson Stealth Pivotal seat and seat post. This is a premium seat made with a subtle perforated vinyl material.

What age is the Kink Switch 20 inch suitable for?

We would recommend this bike for riders that are 166cm/5'5" or taller. THis bike is suitable for adulst and based on UK height data this would also be suitable for a child the ages of 14 years and older. This is only an approximate guide and you may find riders that are slightly shorter or taller can competently ride this bike.

What type of BMX riding is the Kink Switch suitable for?

This Kink Switch BMX bike is designed specifically for street riding, however it will still perform well in other terrains such as ramps, dirt, concrete/wooden parks and pump tracks.

What else should you know before buying a Kink Switch BMX?

The Kink Switch BMX frame has removable brake mounts, this means if you're running it brakeless like many street riders do then you won't have brake lugs on the frame that could easily get caught on your clothing or shoes. This also gives the bike a cleaner aesthetic and if you decide to run brakes everything is included to fit both the front and rear brakes.

The Kink Switch is fitted with a freecoaster hub as opposed to a regular cassette style hub. If you're not familiar with a freecoaster hub it differs from a freecoaster in that when the bike is rolling backwards the cranks don't rotate backwards but rather remain stationary. This is the preferred style of hub of many of the world's top professional street riders as it makes a lot of backwards rolling tricks easier. It's also worth noting that when you pedal forwards you will notice a 'gap' where the cranks move before engaging the rear hub. If you haven't ridden a freecoaster hub before this gap may take some time to get used to.

This bike will require some assembly prior to riding which will include putting the handlebars in the stem, inserting the front wheel into the forks and the seat post into the frame. The minimum tools you will require are: 15mm spanner, 17mm deep socket (for the pegs), 5mm and 6mm Allen keys.
