A surprisingly capable bike. An E-MTB with the weight of an MTB, only 16.3kg! Take the best Trail platform to date, the Spark 900, top it off with 130mm of travel, add a completely silent and powerful electric assistance.
Taking inspiration from the Spark, the objective was a riding position that feels just like a regular bike. We wanted the ability to descend like a trail bike without sacrificing anything when you need to put the hammer down, and a trail bike that can fly up the hill to do it all again on the next descent.
If you prefer a more aggressive ride, the head angle of the Lumen can be easily adjusted through one of 3 positions. The geometry chart is based around the head angle of 65.5 degrees. Our adjustable headset cups allow for a steeper or slacker angle by .6 degrees in either direction.
