    Lower heart rate riding the V20

    I once read somewhere on the internet that a recumbent cycling position produces a relatively lower heart rate but a higher stroke volume for the same percieved effort compared to what the same individual would have exerted if on an upright bicycle. The reason being that there is a lower...

    Midsole cleat position

    My cleats are SPD and I placed them fully backwards but did not drill new holes. They are about 10 to 15 mm behind the ball of my foot. It's almost mid-foot considering the size of my shoe. I adjusted the boom to compensate for the shorter leg reach. My reasons to do this was an attempt to...

    Tweaking on my S40 done - for now!

    It applies to all bikes even uprights, unless it's used for very short distances. The difference with Cruzbike is the smaller user base and the lack of a widely tested and documented fit procedure. For the S40, it's all about that seat, padding and the neckrest. Especially the bottom/lowest...

    Sorry for the confusion, the washer shown in the picture above is not a BB cup washer but I think it is a dust cap washer. It came with the Shimano Sora triple Crankset and the included BB at purchase. First I don't own a Vendetta. I have an S40 and a homemade MBB copy of a cruzbike. The BB...

    T50 on YouTube: International Women's Day Populaire 107K

    Interesting .. I think it 's a question of age. 2 wheeled recumbents would appeal more to the younger/middle aged (40s and 50s) who still have good balance and want to maintian good cornering speeds and maneuverability on open roads. Unfortunately this demographic has strong competition from...

    Looks like I'm gonna be an S40 owner Friday!

    Yeah! I also added a piece of lumbar support from a piece of form that was included in the S40 box. Iam quite comfortable on it. I need the neck rest . Even just for that slight feeling of support. I got too used to it , I guess. However, I had to modify mine with a a piece of PVC that I cut...

    Looks like I'm gonna be an S40 owner Friday!

    For my S40 seat, I replaced the form pad inside the cover and used a yoga mat pad instead. To get the right shape, I traced over the original pad and cut it. I also wanted to make the padding thinner. I found the stock pad too thick for my weight. I felt like I was "floating". I then extended...

    Cruzbike S40 in Nairobi, Kenya!

    I don't have a trainer at the moment. May be later if I find a friend willing to loan me one . For now, it's repeated road tests and strava segments.
