MAC RIDE Wide E-Bike Kit

The e-bike adapter kit you can use with a standard Mac Ride seat that increases the width of the Mac Ride stirrups to allow the seat to fit on a greater number of e-bikes.

The width of a Mac Ride seat's stirrups is 73 mm. To allow for wiggle room and to ensure the stirrups don't touch your frame, Mac Ride recommends a max top and down tube width of 68 mm or less. This fits almost all cruisers and mountain bikes. If your frame is 68 mm or wider, then you need an e-bike adapter.

With the E-Bike Adapter-Wide, the width grows from 73-102 mm, and the recommended width of your top tube and down tube grows from 68 mm to 97 mm or less.
