    Hello, is there any news when the leaf will be available (Germany) and what it will cost? I already have the small carry freedom y-frame trailer. Are the wheels and axels the same, so I could use the wheels of the y-frame as replacements for the leaf-trailer? Regards, Jens

      Yes, Jens all compatible with Y-Small. We are having some problems getting the final production moving. But we had a long list of changes after the testing phase and the information we gathered at the Eurobike and Interbike trade shows. I am predicting January/February 2015. Thanks for your interest and for commenting here.

    Brilliant design, looking forward to its release. Please keep me, U.S. Posted.
    Could it be fitted to a Surly Big Dummy?
    Kind regards Les

      Hi Les,
      thanks for your comment. Will it fit on a big dummy? Thats a good question. It could work but i think the arm might be a little short. We will test this. Another option would be to fit it to the rack. We need to look into use with a long tail bike. i will come back to you on it.
      Thanks. Bob

    Would you have an update about the release date / price (roughly) of the Leaf. Will it be available in the UK ?

    • Bob - Reply

      June 5, 2015 at 15:03

      Hi Nicolas,
      i think the estimated first delivery time would be September. We still have a lot to do. It will be available in the UK through our distributor Extra UK. Final pricing will be coming very soon. So try and be patient. Sorry the news is not better, but we are working very hard right now on making this project work.

    Nice design and a serious contender to replace my Burley Travoy, but why didn’t you use angled wheels like they do on athletic wheelchairs? It provides a lot more stability for sharp cornering.

    It’s the one issue I struggle with when using the Travoy (which uses a similar design): when the inner wheel hits an obstacle (the curb, large stones or branches) on 90 degree turns it topples over, even at lower speeds.

    I guess your design with the larger wheels and lower point of gravity will be slightly more stable but when it hits a larger obstacle on sharp turns it will still topple over, angled wheels could solve that.

    Maybe an idea to test for V2?

      Yuri, this is what Carry freedom designer and mechanical wizard Nick Lobnitz wrote in reply to your comments:

      Hi Yuri

      Visually I’d love to use angled wheels, but there are a couple of problems with them that make them a bad idea for trailers.

      Firstly, the stability of a trailer (or wheel chair) depends on two things, how wide is the distance between where the trailers tyres touch the ground, combined with where the trailer hooks onto the bicycle. Angled wheels do make a slightly wider track, but so does making the axle beam slightly wider.

      Secondly, with angled wheels if the trailer is not hitched at exactly the right height the wheels will either toe in or toe out slightly. This will always mean one tyre is skidding sideways slightly, using your energy to destroy your tyres. The reality is that trailer brackets will never be at the correct height, so the tyres will always scrub.

      Lastly, angled wheels are really difficult to manufacture accurately. This adds to the expence of making the trailer and ultimately its cost in the shops, without offering any major benefit.

      Angled wheels are brilliant on high performance wheel chairs. High performance wheelchairs will often corner suddenly, the wheel angle helps the outside wheel resist the huge forces generated. Also on sports wheelchairs it keeps the top of the wheel tight against the users body making it easier to push, while widening the track width of the wheel chair, which aids stability. It also makes it less likely to flip onto your back when using a chair. And lastly it looks cool.

      ALL trailers that hook onto seatpost (or rack) are less stable and more vulnerable to bumps and corners than ALL trailers that hook onto a bikes axle. Having big wheels, and clever placement of the load shelf make a significant difference between the Leaf and the Travoy.

    hi bob

    What a fantastic design!

    however, i was confused that i need to use a solid wheel axle (non quick -release one) to connect with City, leaf or Y board?

    if so, i just wonder if any conversion / connector that deem fits to connect both the trailer and my quick release rear wheels?

    i am looking forward to having the real product asap :-)

      Hi Peter,
      no not true. The Y and the Y surf both work with solid axle (threaded) and with QR axle. In every box we have a washer to use with the QR axle. The LEAF is fixed to the seat post.
      Thanks for your comments. Best.

    In Oxford, electric bikes are becoming very popular with people carrying kids or pulling kiddy trailers.; when extra grunt is needed .
    Will the Leaf work?

      Hi Dave,
      yes, but the LEAF is not for kids. It’s only for cargo. It folds flat, carries 45 kg fits behind all types of bikes. Check the video on the “LEAF First look” post.

    Is there any more news on the leaf trailer? I am after a trailer that I can unhitch and use a a shopping trolley and this seems ideal. is it in production yet? Thanks.

    • Bob - Reply

      September 17, 2014 at 11:16

      Hi Sara,
      thanks for your question. We only have the prototype at the moment, but the response has been very good so that we can go into production very soon. We are anticipating the release date will be around Easter 2015. The trailer rides really well, as i found out on my trip to the Interbike Show in Las Vegas last week. I was carrying a big ice box on it ;>). Best regards. Bob
