You can make a diverse range - from traditional, classical to new snazzy bikes. Follow the step by step illustrated manual in constructing each model. Once a model is done spin off to have fun with play-rides.
Follow this up by dismantling the bike on your work table - to build up the next fabulous model.
Having completed all the 5 models feel free to give flair to your design skills by creating your very own model from a scratch.
