12-Hour UMCA record on Cruzbike Silvio recumbent bicycle

[ap0lmc]

I just wonder what a Tour De France rider can do on this bike and if it allowed in a Tour De France race.

congrats... very nice,, i love the bikes too

very good , impresionante performance , what is velocity promedio?

[yonifarfan1]

I'm interested to know what are the advantages of a traction system (such as Maria's bike) compared to the more typical propulsion systems found on most recumbents. Weight (shorter chain)?

[Cruzing08]

@yonifarfan1 The Cruzbike Silvio that Maria rode here uses the same drive system as a standard road bike, the key to its efficiency being containment in a small rigid tetrahedron, just like a road bike. Thus, not only is the chain shorter and lighter than on other recumbents, but there is less loss of power to chain idlers,chain guards, chain stretch, and frame flex. She can also use full size (700c) wheels. Most other recumbents can't.

[yonifarfan1]

@Cruzing08 Thanks for your detailed answer: the triangle formed by the steer wheel, the front wheel axis and the pedals is just like the back part of a normal bike. I guess that the driver can use his hands to "push" forward just like in a normal bike. I still have 2 qtions: if the front wheel and pedals moves with the steer wheel, does it make this bent harder to drive? How does such a FWD bent behaves uphill?

[Cruzing08]

@yonifarfan1 Learning to ride any recumbent for the first time is easy for some and difficult for others. Once you learn, it is easy to ride. Cruzbike hill climbing is faster with use of leverage from upper body just like a road bike.

The level or endurance this woman has displayed is superhuman, Kudos Ms.Parker.

Marvelous athelete.

congrats on your achievment & no food for so long time another great achievment.

Holy snapping a**holes, you are absolutely awesome!!!!!! Unfortunately there seem to be no Cruzbike dealers in Western Pennsylvania. Great bike, great ride, great lady! Way to go Maria..congratulations!!

[GTA4Peace]

OMG ! so good ! you are really good bicycle driver ! verry well ! Continue more ! I SAY ! at Gunniess record you MUST BE

[LibertaerUeberAlles]

Those are some nice Cruzbikes!

[MrBillblake123]

That was great! Bravo!!! Hats off to you. Cheers

[sbeer6er]

I was waiting for the wreck, you can't ride twelve hours without something incredible happening.

[Menokokoro]

my dad is getting one of these bikes its going to be awesome

[Trajkociklista]

What's with the constant moving of the whole upper body ? Isn't that tiring on long distances ?

[Yousignhere]

Great job! You are amazing! I want one of these bikes!

[BaganJermal]

Congratulation Maria Parker! I envy you.

[martingrau98]

Did she change out the bike or the wheelset during the day? And does that affect the record attempt? just wondering.

[Cruzing08]

She changed bikes once, at about mile 125, after she fell. The bike had minor damage and you can see see in the video where Maria got scraped up. She was more comfortable on the second bike, without the wheel covers. Changing bikes is allowed by UMCA rules.

ok, maybe not a beast, but a high performance machine...nevertheless D-bomb

[wbh003]

this woman is an absolute beast! And I'm proud to call her my friend : )

[BBhpv]

Congratulations on your effort ! You could easily add lots of miles with a more aero recumbent.

[Cruzing08]

I'm sure you are correct. The Silvio is not designed for time trials, but rather for comfortable and fast commuting or touring, hence the more upright backrest angle and air shock suspension. We are testing a time trial version of the Silvio now, and it should be significant;y faster.

[2204ROB]

Amazing effort! 6 minutes of video doesn't do it (or Maria) justice.
