Stoked in getting a feature in Pipeburn last week with the Concept Z. I'll have some footage up soon. https://www.pipeburn.com/high-voltage-flat-tracker-concept-z-by-ed-motorcycles/

Having a fairly basic understanding of the workings of the brushless DC hub motor I'm curious as to why all currently available Hub motors have poor power to weight when compared to mid drive motors (Emrax, Zero, motenergy etc) ?? Is it simply the fact that development has not occurred in the...

Update of what I have now labeled the Concept Z. Pictures are of the bike on display at the recent Aussie EV Expo at Sydney Olympic Park. I will upload more pictures to the thread with time. Instagram users can jump on to the Ed Motorcycles profile to find a few more build pictures...

Cheers mate. Current design has Air flow channeled from underside of battery box up along front side of motor. I'll dig out some more pics of frame build and CNC work over coming week. Thanks mate. I have been considering using 18650 (25r) cells in a 28s24p layout but I'll throw you an email...

Update after some slow progression on my bike build. Motor is now mounted and battery box mock up complete. A little more fabrication work and it will be ready for battery.

This drive train setup is what Zero is running in the 2017 SR. Zero states 52kw peak and 775 amp. I'll start with a 5.4:1 gear ratio so should get decent acceleration with around 850nm delivered to the rear wheel...

Quick update. 2017 75-7R motor coupled with a Sevcon Gen 4.5 size 6 has been ordered and should arrive mid to late Nov. :D

Hi Dean, I'm down in Valentine on lake Macquarie. Hopefully bike will progress quite alot between now and Christmas. I'm currently held up awaiting parts. Cheers Toby

Cheers Chris, Hopefully in the coming months the bike will be ready for fittment of one of your batteries. ☺️

About two years from when the idea of building an electric flat tracker style street bike first started to now and I finally having a rolling bike to show. Frame and swingarm has been designed from ground up and will suit either an Emrax 228 or zero 75-7 motor and around 5 kWh of lipo.

Hi guys, I received a response from emsiso regarding possible control issues of the emrax LV. Although response was brief I was informed that the 228 LV emrax motor paired with the emsiso emdrive 500 controller was being run in the E- raw bike built by essence motorcycles with no reported...

Hi Luke, I'm looking to put the 228 LV into a bike build. I'm guessing by your response and knowledge of electric motors that running the Liquid cooled version would be a wise choice in a motorbike. I was keen to avoid the extra complication water cooling brings into the design and build but I'm...

Cheers Chris This is just the info I'm after.

Hi Guys, I'm chasing some real world data of the power (kw) output required for cruising at around 100km/h on a elmoto. I understand this figure is going to be somewhat broad with different size bikes, aerodynamics, motor efficiency etc but some figures including bike type and setup etc would...

Hi Scott, Good to hear you are obtaining good results with the Emrax motors. Is the Uni documenting the build online via blog etc? Would be great to see the project. What voltage are you running? Cheers
