Mac Ride

$14.00 USD

Size

Mac Ride is great for cruising. If you cycle on a "cruiser" style bike, or perhaps an an older bike, you'll need an adapter for your stem, so that the Mac Ride front mount spacer fits properly. That's the "quill stem adapter".

There are two sizes of Quill Stem Adapter and it is very important to know what you need. They are not interchangeable.

7/8" or 22.2mm.
1" or 25.4mm.

Sometimes the size is marked on the shaft of the stem, inside the steerer tube, but not always. If you have calipers, you can determine the size you need (the measurement is the diameter).

If you are not sure what size adapter your bike needs, if you are in North America, you can use the "quarter test" pictured here. Otherwise, please check with your bike shop.

Exactly what I needed

I have an older cruiser that required the quill stem in order to install the Mac Ride. Worked great and allowed for easy installation of the Mac Ride.

Works very well

I have an old Miele road bike converted as a commuter. This quill stem adapter worked perfectly and my kids and I enjoy the ride tremendously.

The MacRide team helped me adapt for my bike's quill stem

the MacRide team was willing to review my bike's specs to ensure the MacRide would work for my ebike. They quickly noted that my bike had a quill stem (which I hadn't even noticed until they brought it up). They sent me a link to the correct adapter to help me ensure I didn't purchase the wrong part. Thank you!

Perfect!

I REALLY wanted this bike seat, so I changed my handle bars and shifters to make it so. And SO glad I did. This fit perfect and now I can switch it out between my mountain bike and my commuter. And my husband can put it on his as well. So easy, and so much freakin fun. My three yo loves the MacRide and pretends to be on a space ship. Our first ride was 6 miles and he never once asked to stop!

Perfect for my city bike
