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--- info@mac-ride.com.

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.

Mac Ride LOVES Dropper Posts! But check your dropper post carefully to make sure there is room for the Mac Ride rear clamp to fit around your seat post. This KS Lev dropper, for example, has a mechanism at the side. Unless you have more than the recommended 20mm of space for the Mac Ride rear clamp, the mechanism/cable will interfere with your Mac Ride set up.

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 BIKE

The 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:

Standard Front Mounts | Giant Front Mounts | Quill Adapters | Knock Block Extra

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!

Standard Front Mounts | Giant Front Mounts | Quill Adapters | Knock Block Extra

DIFFERENT SHAPED SPACERS

Cone Shaped Spacers

Some bikes, like Rad Power models, have a cone shaped spacer under the stem. For Mac Ride to be compatible, you need to swap this spacer for a shorter cone shaped spacer to make room for the Mac Ride front mount. So far our customers have been able to find these shorter spacers at their local bike shop. Unfortunately, we do not sell them at Mac Ride. Read more about this solution here.

Cube Bikes - Hexagon Shaped Spacers

Some Cube bikes use hexagonal spacers. Because the inside of the spacers are still round and 1 1/8", these still work well with Mac Ride. The only trouble is the aesthetics...Mac Ride spacers are round, so they might not look pretty and tidy when stacked in a deck together. Functionally, everything is great. Read more about this solution and Cube bikes here.

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).
Some spacers that are not round with flat edges

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 one of our two e-bike adapters to go with your Mac Ride.

As e-bikes are so varied, we have two different sizes. Check out this compatibility information before you make a purchase.

Which E-Bike Adapter do you need?	Top Tube & Down Tube Width
Standard Width (no E-Bike Adapter)	68mm or less
Wide E-Bike Adapter	68-97mm
Extra Wide E-Bike Adapter	97-117mm

Decided you need an e-bike adapter to go with your Mac Ride? Perhaps you'd like some mini grips too! E-Bike Adapter | Mini Grips

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!)

5. BIKE MAKES AND MODELS - WILL THEY FIT?

MAC RIDE COMPATIBLE:

It is always a good idea to check your steerer tube, top tube, down tube and seat post but here are the bikes we have yet to see any compatibility issues with. Click on the link to see which models are already in use in the Mac Ride community.

Giant (special spacer available for bikes from 2011-2014)

Giant E-bikes**

Haibike E-bikes**

Specialized E-bikes (Levo)**

Stooge

Surly

Transition

Trek (lockring spacer available for bikes with Knock Block)

Yeti

YT Jeffsey

**Most E-bikes require an e-bike adapter

SPECIAL SITUATIONS:

Cannondale

usually a great fit
but not for 1.5" steerer tubes
for Lefty's you'll need this special part to be compatible

Trek

Usually a great fit
But if your bike has a Bontrager Knock Block, you'll need this lockring spacer to make it compatible with Mac Ride's front mount

Rad Power

Some Rad Power bikes have a cone shaped spacer
If your bike has a cone shaped spacer, you'll need to swap it out for a shorter one to make it compatible with Mac Ride's front mount

Scott

Many Scott bikes are great with Mac Ride
But some models, like the Scott Spark and Genius, have spacers that are not round. You'll need a Syncros Adapter to make it Mac Ride compatible

6. UNIQUE SITUATIONS

Some bikes a bit unique. The below might help:

IMPORTANT

If you are unsure whether Mac Ride is compatible with your bike, using the online specification sheet for your bike, you can try measuring with a ruler, or talk to your bike dealer or local bike shop. Feel free to email us with questions as well - info@mac-ride.com.
