    Expert Advice on a Used Quest 2.0?

    That would probably work fine. On my Quest V1 I just removed the original rack parts and used an MTB post mount rack. If I needed pannier attachments they would work the same way as what you've illustrated here.

    Expert Advice on a Used Quest 2.0?

    Hello, David, 1. This appears to be the accessory "heavy duty" rack, which replaced the seat support tube and the original, lighter-duty rack included with the original bike. The original rack was, ironically, equipped with pannier side supports. To retrofit, you'll need to find someone with...

    V1, Frozen or locked headset shock

    Hi David, It should be fine if it's stuck. Just like a non-suspended fork. Now if you need an incentive to buy a new Cruzbike, far be it from me to take that away from you... ;) Just joking. I get out over my skis sometimes trying to help people with the old bikes, of which I have many, and...

    V1, Frozen or locked headset shock

    David, I have to agree with everything Robert wrote here. If you look very carefully at the drawing photo, at the extreme bottom, upside down, in pencil, is written "folding bike". That's what these forks were originally designed for. The wear stresses would be different from those applied by...

    V1, Frozen or locked headset shock

    Oops, now I see this post is in the Sofrider section, not the Silvio section. Sorry about that. The Sofrider fork is a little different animal. There are 2 suspension fork shock springs inside the steerer tube, one on top of the other with a separating spacer between them. I have a drawing...

    V1, Frozen or locked headset shock

    David, Here are some photos of the shock section with the boot removed. We are looking at the fork from the back side. You can see the valve stem; the valve has been removed from the stem. You can also see the inner sliding section of the the fork; the diameter is smaller than the steerer...

    V1, Frozen or locked headset shock

    Hi David, I'll take a shot at answering your questions. The shock section of the Silvio 1.0 fork was made by a company called Kind Shock. The fork was built around that shock by a Chinese company, as I remember. Kind doesn't do retail, unless you can find them on Alibaba. The shock itself is...

    Electric boost for T50?

    T50e was developed and sold. Don't know if any are still available.

    T50 Cruzing: measuring driving resistances

    The role of measurement in innovation is always underappreciated. Your approach is systematic and thoughtful. Definitely qualifies as innovation!

    Anyone know what model this is?

    Looks like a V1 Sofrider. Seat height was +1 inch taller than the V2.x, and the wheelbase was shorter (shorter swing arm). It rode very well; easy to learn to ride. This was the beginning of Cruzbike's complete retail bicycles. You folks are still writing the rest of the story...

    CRUZBIKE Sigma

    Yeah, I have a LOT of experience with this bike. The production run was 15 bikes. It is indeed beautiful to look at. But after a LOT of work trying to rectify its handling and steering behavior, it beat me. It was hard to keep on a straight line, and the single u-joint steering caused a...

    Cruzbike v2/K

    Nice machine. This appears to have one of the later, non-suspension Cruzbike forks, which makes everything a lot easier. The challenge is that those are made largely of unobtainium these days. I have a few that I guard jealously. They are the key to the older bikes. Trying to get the OP...

    Cruzbike v2/K

    Hi, I'm sorry you're having difficulties I might have inspired. Lemme try to help. You're going through things I went through a lot building conversion bikes. As is visible in your photos, the triangle bracket, where it attaches to the fork dropouts, has three holes. These are also intended to...

    Cruzbike v2/K

    That' shouldn't be very difficult. The brake cable is probably long enough to cross over. If your brake pads are directional, you might need to swap them. The reason the axle slots in the triangle brackets that hold the wheel are long is to allow you to move the wheel fore-aft as needed to...
