The eZee kits are well thought out and include a spacer washer, which helps the hub motor fit in bicycle dropouts fit for quick release. We now have an open 'C' spacer washer made up from 3/16" stainless that can provide this same functionality to our other hub motors that are installed on front forks which have a recessed cavity and 'lawyer lip' for quick release nuts. With the open 'C' shape, it is possible to slide this over axles that have wires and connectors coming out the end. As well, we have redesigned the torque arm plate slightly, increasing the thickness to 3/16" for greater strength.
