Will the Yepp Maxi Fit on Your Bike?

By Annette 2 years agoNo Comments

Will the rear mounted bike seat – The Yepp Maxi – be a solution for you and your family?

Rear child bike seats are a very versatile design and are compatible with a wide range of bike types.  However, they can not be attached to full suspension mountain bikes.

The Yepp Maxi has two options for mounting to your bike.

Frame Mount to your bike frame – the part of your frame called the seat post tube.

Carrier Mount via a rear carrier.

Is the FRAME Mounted Seat the right solution for YOU?

The Yepp Maxi Frame Mounted seat requires an attachment clamp to be mounted onto the seat post tube of your bike. Please watch the video.

The frame size of your bike to be 51cm or more. To measure the size of your bike frame place your tape measure between the centre of the crank, up to the top of your seat tube (do not measure any of your seat post).  See photo below for guidance. This frame size ensures that the centre of gravity of the child seat is not more than 10cm behind your rear wheel axle. This will prevent your bike from rearing up/tipping backwards with the weight of your child.

Measure your frame size from the top of the seat tube to the middle of your crank

You also need at least 12.5cm of clear space on your seat post tube for the clamp to attach onto and a tube that has a diameter between 28-40mm.  Ideally this space should be near the middle of your tube as the attachment needs to clear your rear wheel by 4cm or more.

Yepp reccommends you need a bike with a wheel size 26- 28 inches – this along with a frame size of 51cm or more will give you the required wheel clearance of 4cm from the top of your wheel to the bottom of the child seat.  

Note: 29inch wheels will not allow enough clearance for a frame mount rear bike seat.
