    jonescg's NEW electric racebike BUILD thread!

    Motorsport of any type is not a mainstream sport. Motorcycle racing is fringe motorsport. And electric motorcycle racing is the fringe of the fringe of the fringe :D All fringe sports are competitor funded. Nothing will change that. If it wasn't for manufacturer involvement ASBK would be the...

    jonescg's NEW electric racebike BUILD thread!

    Some questions for jonescg and Ripperton: Where do you see electric motorcycle racing heading in Australia over the next 3 to 5 years? Are we likely to see electric only races? Or is the future going to be racing with ICE bikes? How many prototype electric race bikes are there currently in...

    Why can't we build this motor?

    Complicity means being involved in something illegal. Perhaps you meant complexity? Have you tried to buy an engine for your MP4-12C? I doubt you could buy one for $50k, let alone $5k. Yes an electric motor is and should be cheaper to make than an ICE, but that doesn't mean new technology...

    Why can't we build this motor?

    I don't understand why the EV community expects to be able to buy the latest technology for peanuts. If this was an ICE forum, would we be complaining about a McLaren engine costing $5k??

    First production fuel cell electric bike

    Sounds retarded. Let's make a bike that you have to buy fuel for, and I bet there will be limited sources of cartridge refills...captive market. No mention of range...because it is shit. The energy density of hydrogen is poor with every storage method invented so far and it's not likely to...

    12V A123 LiFePO4 w/ BMS car battery replacement?

    The voltage output of the alternator is designed to suit the original lead acid chemistry that was in the car.

    12V A123 LiFePO4 w/ BMS car battery replacement?

    Forget about trying to balance the cells while the car is running. Car batteries don't really go through charge/discharge cycles. The battery partially discharges at startup then is float charged while the engine is running. The battery may be required to supplement the alternator for short...

    jonescg's NEW electric racebike BUILD thread!

    The total volume of your radiator is 1.8 litres. I estimate it will hold about half that amount of water, say 1 litre. The coolant flow rate for the AFM-140 must be greater than 8 litres per minute. I'm not sure what your controller requires but if we assume it is at least 4 litres per minute...

    Where are you going to put the radiator and how big will it be? There is no room behind the front wheel and not much above it.

    12 kw rc motor

    OK I forgot this motor is a 4 turn-thousand, to use RC speak :) So with this motor there is no advantage to adding more turns, apart from saving on soldering and MOSFETs :) 600V+ Oh sorry I forgot this is a bicycle forum :) At 600V yes, at 170V no. What you are doing makes sense, and is an...

    12 kw rc motor

    Yes but the motor will make more torque at lower rpm, and require less gear reduction. More voltage and less current is never a bad way to go imho.

    12 kw rc motor

    I don't understand why this motor hasn't been rewound. If I read correctly it is 4 turns? What is there to lose by rewinding the motor? There is more than one way to skin a cat.

    Good thread on old generation RC Lipo cycle life

    The chemistry of a cell refers to the materials the electrodes are made from eg. LiFePO4, LiCoO2 etc.. The form factor of a cell is the physical packaging eg. pouch, prismatic, cylindrical etc.. The electrolyte substrate of a cell is the seperator material that holds the electrolyte eg. lipo...

    jonescg's NEW electric racebike BUILD thread!

    For a donor bike I think you are best off buying a complete running bike then selling the engine. The BEC (Bike Engined Car) guys are always looking for late model engines, especially 1000's. www.ozclubbies.com.au and www.racemagazine.com.au are probably the best way to get in touch with them. I...
