INTRODUCTION
Congratulations on your purchase of this BH ILynx. Enjoy your BH bike!
For over a century, BH has been synonymous with bicycles, cycling, sportsmanship and the will to improve. Many children have taken their first hesitant turns of the pedals with BH and many legendary cyclists built their reputations on our bicycles. The industrial activity of BH (Beistegui Hermanos) began in 1909, in the arms manufacturing town of Eibar (Guipúzcoa, Spain) thanks to the talent and entrepreneurial spirit of three brothers: Cosme, Domingo and Juan Beistegui Albistegui. The company, which initially manufactured weapons, took a radical change of direction after the First World War and set out to provide a fast, comfortable and affordable means of transport for the residents of Eibar. The result was some very lightweight, agile and reliable bicycles. This was the birth of one of the current cycling icons and one of the strongest and most successful brands. From that moment onwards and as a result of their technological advances and commitment to the sport, sporting triumphs and the numerous innovations that BH has brought to the cycling world have ensued.
This manual is designed to help you with the functions and maintenance of your BH ILynx pedal-assist bicycle.
