Power meters have grown in popularity with power-based training. When you use a power meter for indoor training and traditional cycling, you’ll be using the same device to measure power both in Onelap and out of the road. While Onelap works with all models that connect via ANT+ or Bluetooth Low Energy (BLE) using open standards, here’s a list of some of the more popular brands we support: BLE: P35, P35lite. We are not sure whether the devices of other brands can be connected successfully. You can have a try, but the connection results are subject to the actual connections. ANT+: This is supported by Onelap by default, and the connection results are subject to the actual effect.
