1. Which kids seats are compatible with Xtracycles other than the RFA?

For children 4 and under, we recommend Thule Yepp Maxi EasyFit seats for our bikes. The rack-mounted Thule Yepp Maxi EasyFit is the only seat that is compatible with all Xtracycles except the RFA. These seats can hold a child 9 months (with pediatrician approval) to 6 years old and 48.5 lbs. Notice the gray knob under the seat:

Thule Yepp Maxi

The Thule Yepp Maxi for bike seat posts will not work on any Xtracycle. Note that there is no grey knob under.


Thule Yepp Nexxt Maxi

The Thule Yepp Nexxt Maxi will also not work on any Xtracycle other than the RFA.


2. Which seats are compatible with the RFA?

The RFA is compatible with many rack-mounted seats including:

  • Hamax Caress (For children 1 year - 4 years old)
  • Burley Dash RM (For children 1 year - 4 years old)
  • Rear Thule Nexxt Maxi (For children 1 year - 4 years old)
  • Qibbel Air - rack mounted (For children 1 year - 4 years old)
  • Qibbel Junior. (For children 4 years+) 
  • Qibbel Rear Childseat - rack mounted (For children 1 year - 4 years old)

3. What about seats for children 4 years+ on Xtracycles other than the RFA?

Yepp previously produced the Yepp Junior EasyFit. This was a minimalist seat intended for children 4 years and up, up to 77 lb. This seat isn't made any longer, but it can still be found from various vendors online. Xtracycle riders do not commonly use this seat since the Hooptie or SnackBars are an excellent option for children 4 years old and up. 


4. Can my deck have a Yepp seat installed on it?

*The required Yepp adapter for this deck has been discontinued and is no longer available.

5. Do I need an adapter?

If you have an LT1 version 2 FlightDeck, no additional Yepp Adapters are needed as this was the only deck that did not require one. You will just want to make sure your deck is secure to the V-racks with 8 Superhooks.

If you have a SnapDeck, you cannot safely install a Yepp seat on this deck and no adapter will make it compatible. You will need to replace it with an LT1 v.2 FlightDeck and 8 Superhooks.

If you have an LT1 version 1 FlightDeck, the necessary adapter to install a Yepp on this deck is no longer available. You will need to replace it with an LT1 v.2 FlightDeck and 8 Superhooks.

If you have an LT2 FlightDeck, you need a front or rear Xtracycle Yepp Adapter.

If you have an RFA, no adapter is needed to install any of the seats compatible with the RFA.


6. Where on the deck should I install my Yepp seat?

The key to keeping a long tail cargo bike balanced is to center the weight by having the heaviest cargo and passengers sitting closest to the rider. For this reason, here are our recommendations for Yepp seat placement on the deck:

One child in a Yepp seat, no other children on the deck Install the Yepp seat in the front position, closest to the rider
One child in a Yepp seat, an older child or adult riding on the deck Install the Yepp seat in the rear position so the heavier passenger is closest to the rider
Two children in Yepp seats Have the heavier child ride in the Yepp seat closest to the rider

If you sometimes ride with just one child in a Yepp but might need to carry an older child or adult every now and again, we recommend having your deck able to have a Yepp seat moved into either the front or rear position. When that Yepp port is not in use, the hole and or adapter can be covered with a MagicCarpet and the deck will be comfortable enough to accommodate a passenger riding on top.


7. An important note about Yepp seats in the front position.  

You may have noticed that the FlightDeck is tapered, being wider in the front and tapering to be more narrow in the back. Because of the this, when the Yepp seat is installed in the front position, the fit is pretty tight and the seat is not as easy to slide onto the deck as it is in the rear position. When fully installed, the Yepp leg holds bow out ever so slightly. This is normal and how the seat fits in that position. This does not effect the functionality of your Yepp seat in any way. To more easily get the seat to install into the front position, we recommend sliding it over the deck further back on the deck. Then start slowly sliding it forward on the deck until you can fit it into the port or Yepp adapter.


8. What is the difference between the Thule Yepp Maxi EasyFit and the Yepp Maxi Easy Fit?

The Thule Yepp Maxi EasyFit and the Yepp Maxi EasyFit are the same seat, they only difference is what year they were made. Yepp use to be owned by the Dutch Company GMG B.V. In 2016, the Swedish based Thule Group (aka: Thule) added the word Thule and removed the word “EasyFit” from the seat title, but the seat is otherwise unchanged. Some online retailers still have pre-2016 seats for sale so they are still labeled at the Yepp Maxi EasyFit.  


9. Are any non-Yepp seats compatible with Xtracycles?

The Thule Yepp Maxi EasyFit is the only seat we're familiar with for all Xtracycles except the RFA.

There are various options of seats compatible with the RFA. See the list above.
