Several years ago a guy in Manitoba invented zip tie cruise control. He would have his bike at full speed and rely on the cutouts. I asked if a zip tie is less Hee Haw than duct tape. Then he disappeared. When I want to slow I stop pedaling. I recently installed two sets of hydro upgrades from mechanical. I first sent the customers to the local eBike store to get a quote on Maguras: $740. Without cutouts I was able to do it for $85 in parts and $150 labor through frame for quads.
