LEED's 250 Watt motorized bike kit includes zip-ties to secure all e-bike cabling. Cobra Cable Guides are an excellent upgrade to keep the cabling organized on the frame.
Zip-ties work well, but in order to remove them it requires a sharp object such as scissors that must fit between the frame and the zip-tie. This could scratch an expensive bicycle frame. For this reason, we recommend the Cobra Cable Guides if you intend to ever remove the motor bike kit.
