LOWRACER HYBRID SPEEDBIKE -4-

[Peacemaker2027]

With proper design and some math, you can shave half the weight.

[Gansan88]

i like this power bike!

[Jeerka]

It look's evil :) .. like Darth Wader :) ... 

[ChrisLuxembourg]

@Jeerka Darth Vader!

[Jeerka]

@ChrisLuxembourg Sorry :) ... I am not star wars fan :) ... GREAT job btw :D :D

[ChrisLuxembourg]

@Jeerka YES MASTER!

[hussein2000s]

GOOD JOB DUDE WOWOW YOU SPEN 4754HOURS

[rockerojuan]

Wow how much did you spent on this?

[ChrisLuxembourg]

@rockerojuan It's was 4754hours of work.....

[sivrajinc]

@ChrisLuxembourg

I'll bet 20% of that time was spent changing the tyres.

[ProtosCrema]

it looks like an F-117 stealth ;)

[ChrisLuxembourg]

@ProtosCrema F-007 cycle-lane-fighter!

[HeatherSpoonheim]

I do hereby nominate this man as sexiest man on the planet.

[ChrisLuxembourg]

@HeatherSpoonheim Ohlala... Greetings from Luxembourg to Québec!

[terapode]

This was the most amazing thing I´v ever seen. It makes my inventions look like crap.

[ChrisLuxembourg]

@terapode Ola! I've looked in your page, NO VIDEOS! Show me what you wanna create, I will help you!

[DMagers]

Aren't you afraid that the whole thing would look like the last scenes of this video if you got caught out in a rain storm? Especially sitting on the power source :-). Keep up the good work...

[ChrisLuxembourg]

@DMagers No, it's something like a "ride on a canonball" (1943/Münchhausen)!

The power source is provided with fire breaks as usual in the engine room..... 

[54446fftf]

OMFG DUDE SO F@CKING AWSOME how long were u working on this

[ChrisLuxembourg]

@54446fftf Thanks, about 4years!

[54446fftf]

@ChrisLuxembourg nice :)

[ChrisLuxembourg]

Only 1 "dislikes", that's someone of the oil industry...

[JaleelJohanson62]

Very impressive! I like the steering camber that allows you to lean into a turn!

[ChrisLuxembourg]

@JaleelJohanson62 The leaning of the bike comes from the pivot(camber). The wheel camber I decided for a better road holding...

[Drumvain]

Great series, I would love to see this bike in motion. Keep up the excellent work!!

[canamm]

Nice work Chris. We tried the extreme wheel camber and those type brakes on our trike and neither worked very well. The camber ruined the tires in a hurry and the brakes were not very effective at all. We went with drum brakes which work OK, but a lot of folks are using disc, which seems to work the best. We moved camber up to 0 degrees and about 6 degrees caster, laser aligned it and now the steering is awesome.

[ChrisLuxembourg]

@canamm The wheel camber is nearly the maximum what I chose for the bike. Of course the camber ruin the tires, but I change every 1000Km the side. If you don't have a negative wheel camber, your tires are flat in the middle. Here you can turn and change like you want, the tire is definitive broken. I ride mostly with "Schwalbe" or "Continental" tires.

Brakes: I changed the system to hydraulic disc brake, because the 2 V-brakes are really overchallenged with 200Kg total weight....

[jayandersons]

@canamm very cool, ..

[kary1982v6]

when you go into mass production and need a logistics guy you be sure to give me a call.. these are insane!!

[ChrisLuxembourg]

@kary1982v6 I thought, it's an unicum! Ok, if you have the adequate pocket money.....

[FOXYKAT6]

It's beautiful Chris.... Some very impressive precision tooling also :)

You need to find some orders, and then an investor so that you can produce many vehicles for the public. You may be a world changer.

[ChrisLuxembourg]

@FOXYKAT6 Maybe..... But I'm sure the must people don't wanna pedal, they are to lazy! Conclusion, some things never change in the world!!!

[Tricyklist]

Chris, you are a genius. Don't be so modest. :-)

[ehnriko]

I really envy you Chris!... I can only dream of these stuff you are showing off... I love the design, the approach, the concept, the practical dynamics - everything! Plus the fact that you can actually play with your tools and stuff and put it into reality. 5 Stars!...

[ChrisLuxembourg]

@ehnriko Thanks! Envy, that's a bad shape! The workshop tools are buyable and the skills are learnable... Only the hybrid bike, here I needed a very long time. ...And always time=bucks

[TheLiquidKnight]

Would the brushless wheels make two or three wheel drive possible for your next off road hybrid recumbent?

[ChrisLuxembourg]

@TheLiquidKnight Yes, of course! Maybe I pimp out my 6-Wheeler(6x2) into an 6x6 wheel drive! The application possibilities are nearly unlimited, the hub motor is into the wheel. A clever created electric car has got 2 trunk floors, it don't have an engine bay and the flat battery is under the car! I send you something.....

[TheLiquidKnight]

Nice change of direction. I would have swaped chain for belt drive first though. ;-)

[ChrisLuxembourg]

@TheLiquidKnight That's my idea too, but what about if I don't have chain??? So never a chain and the gearbox can be broken! You see, it's possible without a chain on the forced wheel.....

[TheLiquidKnight]

@ChrisLuxembourg Fewer moving parts, less weight; more reliability. Using pedal power to charge cells adds a lot of weight. The consept I had back at school rigged the generator direct to the wheel so as you pedal faster more power goes to the wheel so it would be the same effect as a convensional bike, pedal faster to go faster. At the time the technology wasn't available but I may dust off my old designs and get my grinder out. :-)

[ChrisLuxembourg]

@TheLiquidKnight The problem is not the alternator-battery-motor-combi­nation, the cockpit an the frame are the heaviest parts. With the assistance the mountains are really a facility, I turn always my 65rpm on the crank and the gears only shifted with a button!

But if I wanna recharge the battery only with my pedal alternator I need about 9hours. Here you can see that my human muscle power is limited to 120Watt constant! Other energy sources are the 32W solar roof and the recouperation...

[TheLiquidKnight]

@ChrisLuxembourg Dam those laws of thermodynamics! :-)

[ChrisLuxembourg]

@TheLiquidKnight There's no escape! :o)

[cyraje]

Nice jub dude ...keep going

[ChrisLuxembourg]

@cyraje Keep going??? It's finished! I'm creating now the over next bike...

[cyraje]

@ChrisLuxembourg This is exactly what I meant .... or even developed a little

[ChrisLuxembourg]

@cyraje Highly developed for a bike...

[hybridm0j0]

Hey Chris, what's with the motor attached to the pedals? Did you end up using it as a serial hybrid?

[ChrisLuxembourg]

@hybridm0j0

I ride with that "pedal motor"!!! I'm the charger! It's a geared 24VDC motor, it reaches a voltage of 50VDC with 90 crank rpm. Ok, but I don't wanna ride with 90rpm, my ideal is about 60 up to 70rpm. I calculated & tested: The big chain ring has got 72T and the little 13T. With 60 rpm I reaches a power of about 3AMPs at 40VOLTs=120WATTs. The regulation here: Pedaling=riding. If you don't pedal, the assistance don't work!

[Jer0mmel]

My God, that's quite a project !!!

Will you upload some clips of "the thing" on the road?

[ChrisLuxembourg]

@Jer0mmel

Of course, but later, I'm collecting video material!

[lgalicki]

Holy crap, man! That's an amazing job! Oh, those poor tires... :D

[ChrisLuxembourg]

@lgalicki

Thanks, No broken tires, No business... BUT "normally" it doesn't smoke, so I can ride 1000s of Kilometers with a tire!

[d3nny89]

can i have  the plan's ,too? that's amzing...RESPECT!

[ChrisLuxembourg]

@d3nny89

SORRY AGAIN, PLANS DOESN'T EXISTS!!! ...OR SHOULD I RECREATE A DETAILED PLAN OF 6000PAGES NOW?? WATCH THE VIDEOS #1 - #4, THERE YOU CAN SEE MORE!

[ChrisLuxembourg]

@d3nny89

Dov'è l'inghippo? Volere è potere....

[d3nny89]

can i have  the plan's ,too? that's amzing...RESPECT!

[ChrisLuxembourg]

@d3nny89

Sorry, plans doesn't exists. That was a project from the last 4years...

[superbro950]

Wow thats amazing...you should sell plans....at least more detailed than your videos....so other people can make this...thats glorious and you have my respect

[ChrisLuxembourg]

@superbro950

A plan doesn't exits. I'd create the lowracer hybrid trike in about 4years..... I send you another project that's of course very easy to recreate, the "Lowracer Supersonic"

[dynafeel]

You made a perfect electric car! :O

[ChrisLuxembourg]

@dynafeel

I must pedal and of course it's a bicycle(trike)! The different, I don't need an assurance, I don't need to pay vehicle tax and I don't need a technical control board.....

[MoeBrownNZ]

thats awsome!

[ChrisLuxembourg]

@MoeBrownNZ

Thanks!

[Arjanatricx]

yesyes, well artistry; show some running please, thx...

[ChrisLuxembourg]

@Arjanatricx

Ok, akkoord! Maar allereerst moet ik een paar video's verzamelen.....

[Pixouf]

Niiiiiiiice video !

[ChrisLuxembourg]

@Pixouf

THAAAAAAANX!

[Guds777]

KILLER..

[ChrisLuxembourg]

@Guds777

My job is the contrary....

[teknomage2012]

well done, congrats on an equally cool rig.

[frontlicker]

Love to see some footage of you flying by in the LowRacer Hybrid. Your wide angle mounted shots don't give a clear view of your recumbent in action. A couple panning shots and maybe a tracking shot with a car trying to keep up and some info on how fast your trike goes would be fun to know.

[TheWingflyer]

What's the efficiency of that pedal generator?

[ChrisLuxembourg]

@TheWingflyer

Maximum! If I cause a short circuit, I cannot pedal it.....

[Signmacula]

Nice good on the upgrade! But the ending concerns me that you might eventually put a jet on this thing! Do you have regenative breaking? Hubmotors is half way there....Great work all the same! So when you make it big, where do I send my resume?

[ChrisLuxembourg]

@Signmacula

Thanks! Yes I've got a break recouperation. But the recouperation "raped" the battery and the motor!

I'm trying out a new LiPO battery with 20 Kokam cells and a lot of SuperCaps, so I've got 37V/27Ah/65C.

Well, I think I couldn't make it big, only for the price of the battery you got a new small car... Maybe in the next 10years the price of LiPOs are going down, but today it's HiTec!

[aquapulsefuel]

If you put some Kevlar at the back and some at the sides you will be bullet proof. Haha

[aquapulsefuel]

You need some lighting bolt decals on the side tom break up the black a little . I love this machine but please be carful of the road surface at speeds of over 20km. Very unforgiving on my recumbent and it appears that you vision is restricted direct in front of you. I maybe wrong here but I would hate for you to get out of shape. Good work. Can't wait to see more footage of you on a road.

[ChrisLuxembourg]

@aquapulsefuel

Don't worry about it!

Did you really thought I have forgotten all these safety precautions???

That's my job! In front there's a hidden 6cm thick Kevlar bumper bar and over me a double rollover bar. The bike has got a double frame and the window panes are unbreakable! I also invested much savety in lights with an official approval number and Scotch 3M reflectors.....

[Tybone7]

Lets see it in action.

[ChrisLuxembourg]

@Tybone7

Olala... At first I must collect a lot of video material!

[amidesign]

Excellent ...

You have thinking that the camber angle increases rolling resistance

I read for the PAC -car II : the rolling resistance increases from 0° to -4°. Then, remains

stable as the camber angle increase from -4° to -9°

[ChrisLuxembourg]

@amidesign

Yes I know, I only can drive the special tyre "Schwalbe Marathon plus 20 x 1.35" Also a flat tyre on that 100Kg bike is a disaster! But the steering works great and the roadholding is encredible!!! The only thing I wanna change are the front brakes. I am trying the Magura Gustav-M with a 210mm disc, because the recouperation of the motor doesn't work until a stop!

[charlie1der]

Looks great!

[ChrisLuxembourg]

@charlie1der

Thanks!

[karch76]

that's a mean machine!!! You rock!

[ChrisLuxembourg]

@karch76

Thanks!

[dazzerre]

Ist jetzt doch verdammt viel Elektrik drinn.

Bitte mach auch noch mal ein Video von der Fahrt, wenn du Zeit hast, aus veschiedenen Perspektiven.

PS. Deine Reifen Rechnung will ich nich haben ^^

[ChrisLuxembourg]

@dazzerre

Viel Elektrik, es geht gerade noch so. Zur Steuerung wurden 120meter 0.75mm² Doppellitze verarbeitet. Alle Hochstromleitungen so kurz wie möglich und in 6mm²&10mm².

PS.: Mein Reifenhändler muss auch leben.....

[dazzerre]

HA 1. WIe immer super Arbeit !!!

[ChrisLuxembourg]

@dazzerre

Nun ja, hat ja auch 3Jahre gedauert! Gute Arbeit braucht einfach seine Zeit.....
