Almost certainly, your bike is compatible with Mac Ride. But there are a few tricks to be aware of so you can order the right adapters if needed. And there are a few exceptions too. We also have a Mac Ride gallery so you can see just a few of the bikes from around the world in action with Mac Ride here! Any further questions, please reach out--- firstname.lastname@example.org.

1. WILL MAC RIDE FIT YOUR BIKE?
This guide explains how to check your steerer tube, your frame and your seat post for Mac Ride compatibility.
CAN I USE MAC RIDE WITH A CARBON FRAME?
Absolutely! Mac Ride mounts to the steerer tube and seat post and does not touch your frame:)
CAN I USE MAC RIDE WITH A DROPPER POST?
Absolutely! When mounting the rear clamp, be sure to go on to the base of the post, and not the part that drops.
CAN I USE MAC RIDE WITH A "NORMAL" SEAT POST (NO DROPPER)?
YES! Mac Ride simply clamps to the seat post itself. You can choose where to place the rear clamp to establish the right level of slope for the Mac Ride saddle for your child.
2. CHOOSING THE RIGHT FRONT MOUNT SPACER FOR YOUR BIKEThe size and type of your steerer tube will determine whether you can use the standard Mac Ride mounts or whether you need an adapter. Mac Ride comes with two front mount standard spacers, size 1 1/8". If you do not have a common bike, you will need to purchase different mounting spacers on our shop:
Check out the information below to help you determine what you need:

WHAT IS A STEERER TUBE?
Great question! It's the silver part of your bike, below, that goes down and connects to your forks.
You are looking to measure the diameter of the steerer tube at the portion that sticks out from your frame (where it says 1 1/8", below). This is the part where the Mac Ride front mount fits, so it is the part that counts!
WHAT IS A TAPERED STEERER TUBE?
Sometimes the spec on your bike will say 1 1/8" with a "tapered" steerer tube, and then give additional dimensions, which can be confusing. As long as it's 1 1/8" at the part above your frame, the rest doesn't matter for fitting Mac Ride. So don't be worried about "tapered".
WHAT IS A THREADED STEERER TUBE?
For bikes with quill stems, they go inside a threaded steerer tube. These bikes, some commuters and older bikes - will need a quill stem adapter, either 7/8" or 1". For North America, there is a sneaky way to check what size you need, with either a Canadian or US quarter:
ORDERING FRONT MOUNTS FROM MAC-RIDE.COM
The below mounts and adapters are available on our shop. If you have a standard steerer tube, and two 1 1/8" spacers are not enough, you can always order more!
See here for a guide to tubes that are not Mac Ride compatible
3. E-BIKE COMPATIBILITY
Mac Ride is brilliant for e-bikes! Unless your e-bike frame is very narrow, or your battery pack is at the back, you will need our e-bike adapter to go with your Mac Ride.
As e-bikes are so varied, check out this compatibility information before you make a purchase.
Decided you need an e-bike adapter to go with your Mac Ride, maybe some grips too:

SEAT POST DIAMETER FIXES
For thinner seat posts - You can DIY a rubber patch to thicken the post and make Mac Ride compatible with your bike's seat post.
For thicker seat posts (up to 34.9 mm) - Remove the domed nut from the end of the Mac Ride rear clamp hand screw. This will allow the clamp to open up to 34.9mm. The domed nut is only there to protect the rider's inner thigh from the potential sharp edge of the screw when clamped to very small diameter (27.2mm) seat posts. It serves no other purpose. As long as you don't need to go larger than 34.9mm, by removing the domed nut, there are no changes to the function of the clamp. A heads up-- the nut may be stiff to unscrew as there is a small amount of threadlock on the inside.
This fix is not suitable for seat posts that are larger than 34.9mm (although we do not know of any... at this time!)

6. UNIQUE SITUATIONSHere is a summary of some of the bikes where Mac Ride is not compatible:
WHAT STEERER TUBES ARE NOT COMPATIBLE WITH MAC RIDE?
- 1.5" - Threadless steerer tube - less common and being phased out - not compatible with Mac Ride (some Cannondale Leftys have this tube).
- Spacers that are not round, as is the case for example, with some Scott Genius and Scott Spark spacers (note in the image below that there is a flat edge; this is not compatible with Mac Ride's front mount).
