Hi All. I wanted to let you know that yesterday was the first time I tried CYC Photon. In short, for me it exceeds all expectations. We went for a few laps in Tihany (52 km), mountains, valleys, asphalt, dirt road, grass. With very steep climbs. The whole system provides an amazing experience. On flat terrain, you can reach a speed of 45-50 km/h either by rolling or using the throttle, all this with a 38T gear in the front, 11T in the rear. I think 60-65km/h can be easily reached with the 50T factory gear. The torque sensor is incredibly sensitive, it is possible to maneuver perfectly and sophisticatedly on steep dirt roads and through roots. We went up such steep dirt roads and asphalt roads without any problems that I didn't dare to dream about it. I also monitored the engine temperature, it stayed around 30 degrees on average, it went up to 40 degrees when under heavy load, on a very steep road or when using the throttle. That's a long way from 80 degrees. As far as I know, the engine would shut down above 80 degrees. So I think it can be loaded a lot. For me, 38T gears are the golden mean, I don't think I'd want to drive over 45km/h, it's already an experience, we passed factory bikes with Bosch or Panasonic motors as if they were standing still. It's seriously fun. This also ensures very good climbing ability even on the ground. Many times I didn't even use the two largest rear cogs, 37T and 46T. There is plenty of power and torque to pull you up in critical situations on steep dirt roads. With large rear gears, it is a dream to maneuver on a steep dirt road, between roots. We drove 52 km, approx. 20% capacity is still left from the battery (840wh battery). I think the system can do about 65 km in very demanding mountain and valley conditions, going up several peaks, sometimes even using the throttle. On flat terrain, I think it's probably 100km or more. I think this is absolutely one of the best engines on the market right now. Thanks
