    I rode a Dynamic shaft drive

    I rode the Dynamic Sidekick 7 speed shaft drive folder for about 3 weeks. I bought it with a 30 day trial offer. The people at Dynamic are very good to deal with.
    I really liked having an internal gear hub, and being totally chain free by having a shaft drive was wonderful.
    So, why did I send it back? Mainly, it did not fit my long legs, without going beyond the seatpost min mark. I did not want to do that long term. The new model will have a one inch longer seattube, and so it should fit me, 6ft tall with long legs. I could have added a ButtBuddy to gain 2 inches, but I did not want to invest that in the 7 speed bike. I would only own one with the Nexus 8 speed hub. I needed a lot more low range, without giving up on the high range. The Nexus 8 speed will do that for me, (307% range instead of 244%). They did not have the 8 speed available at the time, and I did not know that the 7 speed would not work that well for me until I tried it.
    The bike also did not fold well, did not stay folded, and rarely stood up by itself. I used it as a "lay flat" by only folding the handlebar post, lowering the seat, and rolling it into the backseat of my car. If I get a new one when they become available in Oct, I might cut out the frame hinge, and weld the frame to make it a layflat. The folding is as bad as a cheap folder, nothing like a Bromptom or Dahon. Dynamic wanted to have Dahon make frames for them, but Dahon was not interested. Dynamic was receptive to my idea that they add a lighter layflat to their line. This bike was very heavy, 32 pounds.
    I may buy the Crosstown 8 instead from Dynamic. It is a full size, non folding road bike, but it is only 27 pounds, and has a wide gear inch range since it has 700C wheels. I would opt for the lower range drive, but you can read their gear inches and decide for yourself. If I add folding pedals, and remove the front wheel, I could fit it in my backseat as a layflat. I drive a very small 1991 Civic SI hatchback that I bought new and really like.
    I would definitely recommend a Dynamic bike to anyone who wanted a very clean and low maintianance bike. If you get the Sidekick, I would recommend upgrading to the 8 speed. You would have a bike that rode and maneuvered well with its 20" wheels, and can work well as a layflat, but remember it does not fold well.

    I'm a sucker for shaft drive, having had a broken motorcycle drive chain crack my crankcase on my Suzuki SV650, I've only ever had shafties since.

    It seems like a natural for bikes that aren't all about weight.

    Damn, I wish I had known about this bike before buying my Dahon. It even has the springy saddle...

    A couple other things: Dynamic's site says that it's only good for people with up to 34" inseams. Is this wrong or was it not there when you were researching?

    I have a '98 Civic hatchback, which is just starting to rust out on me now. (162k, 9 Chicago winters) Before that, I had an '85 CRX, (193k, 14 Chicago winters) which I also really liked.

    The new Si's have no torque at all, and don't feel very quick, especially for the money. We wound up going with a Matrix. Would've gotten the Yaris, but the wife didn't like it and it wasn't quite big enough for when we have kids.

    Also: What's the deal with changing flat tires on the rear wheel? Does the wheel come off and re-mount easily?

    The 34" inseam applies to the next shipment arriving in October. The new ones have a 15" seattube instead of the 14" of the old ones. I had one of the last one ones. They are sold out until October.

    Removing the rear wheel is about as quick and easy as any bike. Putting the rear wheel back on is actually quicker and easier.


    On the next new bike I get, I will be putting airfree foamfilled tires on, so I will only be messing with the wheels once. I have been using airfree tires for about 35 years now on my 700C wheels. I like things clean, simple, and maintanance free.
