    LOWRACER-MANIA

    Ok, I decided to help you... Which bike do you wanna create? Here a little collection of my bikes: http://zeus2.zap.lu/page/YQXLbAjjIt/1dv01Yms1X2/?snzeus=298ZpCol2APBkS0 :|

    A high racer is better for traffic situations, because much better balance and better to see from car drivers. A low racer is better for races, because it has got a lower air drag(Cw) and it's much faster. But here the problem, the low racer has a nervous trajectory, you must learn to balance...

    I'm to be of two minds about the electric assist lowracer. We have strong regulations about e-bikes and electric assist bikes here, normally at 25Km/h(15mph) the motor cut off the power! :cry: The lowracer "2FAST4U" without motor I can pedal up to 60Km/h(36mph) in the flat. I can't believe...

    Nope, not dangerous! But for some ultra lowracers you will need a gun license! :lol: :lol: :lol: The chain rings are made from a disc saw blade: st2ob5LRTfc

    LOWRACER-MANIA

    Hi guys! Before a long time I've tested a new system to power my lowracer bent bikes. It should be a low-maintenance construction, so I decided me for a front drive! The drive system works reliable and I decided to create a little family of 5 lowracers... _a79m8YvbQA Of course you can...

    CRYSTALYTE 5404 HUB MOTOR - INCREDIBLE TORQUE!

    Not nearly, remember that I don't have a chain on my motor. Many hub motors and many controllers lost her life... :roll: The problem was not the low speed, it was the start from a holdup in a mountain!

    CRYSTALYTE 5404 HUB MOTOR - INCREDIBLE TORQUE!

    You know, 37Volt is by the law the maximum here. The 4110 12-FET 35A controller is converted into a 50A controller, at 55A I've a cut off. The motor "sucks" 65A/phase, feed line cables are 10mm²!

    CRYSTALYTE 5404 HUB MOTOR - INCREDIBLE TORQUE!

    Thanks! The lowracer is an easy creation, without or with electric motor you can compare with a ride on a cannonball. So you can hit 60Km/h in short... :twisted: BUT, you must learn to ride this ultra lowracer! :shock: A seat high of 13cm from the ground is requiring an excellent balance...

    Thanks for your feedback! :o The videos and the own music are very much work for me... ...And then, there are idiots which only click "dislike" :twisted: It's not nice to be insanely jealous, so I cannot help this guys, they need a psychiatrist! Now to the motors :mrgreen: It's difficult...

    HEADWAY LiFePo 38.4V/48Ah BATTERY

    No, but it's ordered! I need 4 pieces. The module is simple created, no microprocessors or something else. Exactly this one: http://shop.lipopower.de/Balancer-15A-fuer-4-Zellen-LiFePo4-Lastmodul-mit-LED The choice is everyone and every LiFePo battery...

    BIG LIPO EXPLOSION

    I cannot bemoan the loss of the LiPo... I don't want the LiPo back again, I divided the blocks into single cells, it looks like the nuke in Fukushima. :twisted: The Headway is the best battery I've ever seen! But I think it's an A123 copy, isn't it? The Price is only 1/3 of the high power...

    BIG LIPO EXPLOSION

    I think the cylindrical are the better choice, because every cell has got space around! Ok, that's nothing if you wanna create an ultra compact Battery, but for a longer cell life of course! AHHH.... My cat? Likes dead- and thrash-metal... http://www.youtube.com/watch?v=CcS33oooL-8...

    HEADWAY LiFePo 38.4V/48Ah BATTERY

    For the first I've done a few tests with these cells. 5PryI-zfUwg After all the tests I decided to complete the battery pack. The cells are fixed with special holders on a 1cm thick Pertinax plate. Incredible power and endurance! A REAL SOLUTION!!! k2J0p-uOuC4

    BIG LIPO EXPLOSION

    That's right! 3P12S LiFePo... Every cell has got an own characteristic and an internal resistance. So, some cells are "good" and some are "bad" :roll: If you've got the "bad" cell in your batt 12S(nothing parallel), under load this cell warm up and kills the endurance of the whole pack! If...

    BIG LIPO EXPLOSION

    No, not really! Only for tests all cells are in series! In a series circuit I've got every where the same current! :lol: Exactly I change my voltage from 37V to 38.4! :roll: I've got 12 cells series and that in 3 rows. For easy unstanding: 12 X 3.2V = 38.4V Later the 3 rows are running...

    BIG LIPO EXPLOSION

    If you are running a 37V nominal voltage system, at 31Volts the controller turn off, that's safety system against undervoltage! You can only restart controller if there are 33Volt.

    BIG LIPO EXPLOSION

    The voltage of only one cell pack (3x4500mAh) slips away. The balancer couldn't hold the voltage of 4.2Volt and the cells are blowing up more and more until it catch fire. Now the LiPo Pack is solding himself, the 8mm brass bolts are so hot, they cause a short circuit to the neighborhood! Then...

    BIG LIPO EXPLOSION

    No problem! You've got the good luck that your house don't burn down in the neighborhood! With only one Lipo battery it's possible to destroy half Luxembourg. That's a refurbishment to all terrorists, don't take bombs, take damaged LiPo batts! :lol:

    BIG LIPO EXPLOSION

    I'm riding today with the new LiFePo's, incredible power! Very easy handling! That means no bomb under the butt! :twisted:
