Ned Posted December 13, 2011 Share Posted December 13, 2011 Sup bitches! Badgers are going all green and shit! (waits to be kicked out of the gang) Just joking, we still love two smokes etc. Anywho, Me and Cam are building a 'secret' new years weapon for beach and camping ground 'racing' and we needed a test bed for the motor controller (as it'll be electric) so made me a starter motor bike tonight. so bike with friction drive starter motor. pushed the solenoid to 2mm from engaging and used that as the on/off switch for now. Will have a fully functional motor controller at some stage though. Simple bracket to hold the starter motor at the top even simpler one to hold it at the bottom. 7-RrZSXewLM Had a look with Cam just before and the theoretical max speed is 26KPH which is enough for some fun/take us to the bakery for lunch. watch.....this.....space..... xoxo Ned Quote Link to comment Share on other sites More sharing options...
rot808 Posted December 13, 2011 Share Posted December 13, 2011 yes, i will ride this, and yes, i will be drunk well done Quote Link to comment Share on other sites More sharing options...
KKtrips Posted December 13, 2011 Share Posted December 13, 2011 that isn't 10 cylinders Quote Link to comment Share on other sites More sharing options...
Ned Posted December 13, 2011 Author Share Posted December 13, 2011 haha, you may ride it, only if you are drunk and KK, i know 10 cyl bike will be built in the new year! don't you worry Quote Link to comment Share on other sites More sharing options...
phr34kr Posted December 13, 2011 Share Posted December 13, 2011 This is awesome. What sort of RPM do starter motors run at? Would it be possible to utilise the bikes gear shifting if it was chained to the front gear-set? Although i do love how awesomely simple the friction drive mounting worked out.

Ned Posted December 13, 2011 Author Share Posted December 13, 2011 You could if you setup a sprocket on the motor and used one of the front sprocket gears as your reduction drive and then used the normal rear gears and left the front one in the lowest mode. You should probably even change the front sprocket to another smaller one to get another reduction drive. Quote Link to comment Share on other sites More sharing options...
phr34kr Posted December 13, 2011 Share Posted December 13, 2011 Hmm actually i think i have somthing that would make my life even easier two of these http://www.andymark.com/product-p/am-0255.htm into one of these http://www.andymark.com/product-p/am-0145.htm controlled by two of these http://www.robotmarketplace.com/products/IFI-V884.html would only need to sort out mounting which should be simple and i would have a 7 speed ev bike need to see if i have a suitable bike lying around tomorrow.

Ned Posted December 13, 2011 Author Share Posted December 13, 2011 40 amp controller isn't much. We're building TWO 220A cont and 780A peak controller for our new years beast The car starter stall current is HUGE! couldn't even measure it on our current clamp meter, and that does to 250A+ haha. Draws 70A running without a load... but thats with the solenoid engaged as well which draws quite a bit. 120A controller; http://www.dealextreme.com/p/120a-bec-s ... otor-72655 Quote Link to comment Share on other sites More sharing options...
phr34kr Posted December 13, 2011 Share Posted December 13, 2011 i suppose not was aiming on using 2, thats 80amp continuous, although i have many more available (another 10 or so) i could just wire in parallel, i wonder how good those deal extreme motor controllers are? I at least know the victors are reliable and have proved their stuff in competatitve robotics working much harder than they should, as well as the fact they are available for me to use for free along with the motors and gearbox.

Ned Posted December 13, 2011 Author Share Posted December 13, 2011 Why? Shouldn't you just be happy i finally built a bike? edit; also, re-read the thing that says it's only a test bed for some motor controllers we're building Quote Link to comment Share on other sites More sharing options...
grunta Posted December 14, 2011 Share Posted December 14, 2011 i was so excited about seeing 10 2 strokes, then u delivered that!!! ouch! my face balls! u owe me 12 seconds of my life since i watched the video! Quote Link to comment Share on other sites More sharing options...
