    My Pine Conversion

    Wow! Beautiful Bike! I've always thought a wooden frame would make a very nice material for the main frame of a cruzbike. The Front triangle can remain an alloy but the main frame that supports the seat and rear wheel can be made of wood. When well engineered, wood can be very light, yet very...

    Higher gear, learn to spin or enjoy coasting?

    ... wish it was possible to ... wish it was possible to edit a post :-( ... I meant an 11 tooth sprocket. Generally I find it easy to maintain a higher cadence on my DF than on my MBB recumbent. But it has been getting better with time. So I believe with practice I can probably attain a...

    Higher gear, learn to spin or enjoy coasting?

    Adding an 11 tooth cog wouldn't hurt I think practising to ride at a high cadence generally even at 30Km/h will help you to maintain stable and clean spining even at the higher speeds. And I agree with Charles learning to ride hands free allows your legs to develop a cleaner spin without...

    Silvio 1.0 is still, an amazing machine. AndrewBaloga, I'am very happy you finally got a Silvio!! Congratulations! The first time I saw a high resolution picture of a silvio 1.0, I was amazed at the quality of the engineering. Still, an amazing machine. I still enjoy watching this early video...

    Vendetta is a climbing machine

    Dan,  ... If the other pedal Dan, ... If the other pedal arm is at the top of the downstroke where would your leg be? It would be on the top of the pedal arm because you're clipped in. You don't have a choice. If, as you say, you "pull it up on my clipless pedals" is that...

    Vendetta is a climbing machine

    Dan (aka psychling),  .... Dan (aka psychling), .... After the first downstroke the DF cyclist leans on the handlebars and lets the other pedal meet the other leg. I agree with you here. ..... From that point on the DF cyclist isn't lifting himself up against gravity. ... I...

    Vendetta is a climbing machine

    John, in my opinion, yes the John, in my opinion, yes the total power output used to move an equal size of mass up the hill is the same for both a recumbent and an upright. However, on the downward pedal stroke of an upright, the force applied on the pedal is a sum of the weight applied by the...

    Silvio 2.0 and 27 Degree Seat Angle

    First, I must say that First, I must say that personally, I love the new Silvio 2.0 and the new seat angle appeals to me. If I had the funds, this would be the bike for me. That said, I want to re-assure Lisa and others that, as Charles Plager put it, generally, it is easier to raise a...

    Vendetta 2.0 unboxing and build

    Wow! I didn't know that Wow! I didn't know that Velcro is strong enough to hold a seat pan in place even under load. Is there any nut and bolt somewhere to secure the the seat?

    My Vendettas

    Wow! Built with precision! Wow! Built with precision! Those hydroformed tubes look very light too! probably the new V is significantly lighter than the current one. What are the short pipes just beneath the main frame where the rear stays joins the bottom of the main downtube?

    new blog about new Silvio

    Charles, I see your point Charles, I see your point about 32 mm tires. But I think the main problem, which most people are overlooking here is the road bike components compatibility and specificially road bike caliper brake compatibility. John wants to enable road bike users to swap the...

    new blog about new Silvio

    Vadn1, Its interesting that Vadn1, Its interesting that with disk brake tabs now part of Silvio-2.0, you noted that you can fit more sizes of wheels from 700x28 (iso 622) to 26" (iso 559) or smaller wheels as long as the hub is disc brake compatible and the tire narrow enough to fit into...

    new blog about new Silvio

    thebean, I 'am not a thebean, I 'am not a designer, but I have some engineering background to my education. I also homebuilt my own bike by looking at the cruzbike design, mostly becuase I could not afford a cruzbike. I however follow this forum with interest, and maybe one day I will...

    new blog about new Silvio

    Silvio 2.0. Serious alround "Road" bike. Period. To answer the forum member called "thebean", about the 33 to 38 degees seat angle, you need not worry becuase the new silvio design means it's possible to adjust it, within some limitted range by using washers and extra padding. This is...

    Potential instability once pedalling

    Hello WilG, I'am by no means Hello WilG, I'am by no means an expert like John, but it seems to me that what you are experiencing is pedal-induced steer. If this is the case, then there is nothing wrong with your bike. This is an expected behaviour of the cruzbike and indeed any other bike...
