We do not sell ByK Bikes direct online on our website however you may have purchased a bike from one of our many retailers and require assembly instructions. ByK Bikes are boxed 85% assembled. The final assembly required includes the installation of the handlebars, front wheel, pedals and saddle, adjusting the brakes and tuning the gears. Please note that we do recommend you take your ByK to a bike shop to have it built and/or repaired by a qualified bicycle mechanic. Damage caused by incorrect assembly is not covered by your warranty. Please contact us at with any questions regarding assembly of your ByK Bike.


At ByK Bikes we want to make sure you love your ByK as much as we love do so we will do everything in our power to make sure you are a happy ByK customer. If you’re experiencing an issue with your ByK, we want to assist you in resolving that issue. Please always contact the authorised ByK distributor or retail store where you originally purchased your ByK Bike as they are going to be best able to support you physically and in a quick time frame.
