Vanhulsteijn. Founded seven years ago as a design studio with the focus on interior design, the firm is now outputting this wonderfully shaped bike.“Herman van Hulsteijn built 2 years ago a prototype of this bike for personal use.” With more and more people asking for their own, Vanhulsteijn is now kicking them out for production. Check those curves. Big fan of the Grand Prix tires as well. Available as a two or three-speed.
